Foreword 

The SolarLog 400e is a newly designed device which provides the system operator with 

complete data recording and an extremely flexible data editing and formatting. 

The SolarLog 400e offers excellent functionality - for local use only and in case of a desired 

connection to the Internet for remote queries - with easy handling and without extra 

charge. 

One special feature is that the SolarLog 400e cooperates with various inverter providers 

independently from the manufacturer. The aim is to support as many inverters as possible 

in order to permit operators a uniform platform for data evaluation and analysis. 

Contrary to other competitor data logger products the SolarLog 400e reads out the system 

data directly from the inverter which facilitates the immediate detection of system failures. 

The SolarLog 400e is a slightly modified version of the previous model SolarLog 400 into which 

hardware and software enhancements have systematically been included with a special 

focus on an improved and easier installation. 

The SolarLog 400e has been developed starting from application in practice and is 

continuously improved. Upgrading with updates is possible at any time. Thus, in the future, 

you will be able to benefit of new functions. 

The handling via an internet browser - independent of the operating system used - is 

unique and future-proof. You will still be able to operate the SolarLog 400e with „Windows 

2015“. 

We wish you successful operation and many sunny and “yielding” days. 


Scope of supply 

The SolarLog 400e will be delivered with the following components: 

1. SolarLog 400e – central (host) device 

2. Connector-type power supply unit 12 Volt 

3. Manual 

4. Data cable for connection to the first inverter. An adequate data cable for the 

respective inverter will be supplied. 

The SolarLog for Fronius comprises two data cables and a terminal plug. 

The SolarLog for Kyocera comprises one data cable and a terminal plug. 

5. Drilling jig for wall mounting 

For the PC or network connection you will need an additional network cable (RJ45-CAT5 

or CAT6) of the required length. 

Furthermore, you will need adequate cables for wiring the inverters among each other. 

Installation instructions 

Note: Please carefully read the following instructions before connecting the SolarLog 400e to 

the inverter or to a PC. 

Installation of the SolarLog 400e includes the following steps: 

1. Connection to the PC and/or network 

2. Connection to the inverter 

Please strictly adhere to the order of actions described in the following. 


Connection to the PC / Network 

The SolarLog 400e is equipped with a standard Ethernet-RJ45 network port which can be 

connected with any commercial network cable. Speeds of 10Mbit and 100Mbit are 

supported. 

In general, any PC network technology may be used to connect the SolarLog 400e . The 

following technologies are available: 

1. Direct cable connection 

2. Connection via a network router 

3. Connection via mains (Power line) 

4. Connection via radio network (Wlan / GSM) 

The instructions described in the following refer to the operating system Microsoft 

Windows, versions 98/ME/NT/2000/2003/XP/Vista. 

The network configuration has been divided into the following steps: 

Step 1 – Determine your own network address 

Step 2 – Connect SolarLog with network cable 

Step 3 – Configure the SolarLog network address 

After these 3 steps the SolarLog network configuration is completed. 

Step 1 – Determine your own network address 

If you already know the network address (IP address) of your PC, you may directly 

continue with step 2. 

Each and any appliance connected to a network has got its own network address. This 

address must never be used twice, i.e. allocated to a second device. 

In order to determine the network address of your own PC, please proceed as follows. 

Open command prompt (also called DOS window) on your Windows PC. Then enter: 

ipconfig [Enter button] 

The following screen appears 

Ethernet adapter "LAN-connection": 

Connection-specific DNS suffix: 

IP address. . . . . . . . . . . . : 10.31.1.1 

Subnet mask. . . . . . . . . . . : 255.255.255.0 

Standard gateway . . . . . . . . . : 10.31.1.254 

As you can see from the example, the IP address (network address) is „10.31.1.1“. This is 

your PC address. 

Please make a note of all 3 indications, i.e. IP address, subnet screen and standard 

gateway as they are required for further configuration. 

Important note: In the following description we will always refer to this example address. 

Of course you will have to replace this address by your own accordingly. 


Step 2 – Connect network cable 

Now connect the SolarLog 400e via an Ethernet-RJ45 network connector cable with the 

network card at your PC or, if available, with your network router. 

Please note that you will have to use a so-called “crossover” (twisted) network cable if you 

want to directly connect the SolarLog 400e to your PC. 

Tip: If you have available a crossover network cable, you should use it to directly connect 

the SolarLog 400e to your PC, if possible, for the initial configuration. This applies especially 

in case you intend to do the networking via power plug. 

As soon as the SolarLog 400e has been allocated a fix IP address, the final network 

configuration may be set up. This step-by-step procedure is recommended to allow quick 

troubleshooting. 

Step 3 – Configure the IP address 

In the next step, the SolarLog 400e will have to be configured with a network address (=IP 

address) . 

The “delivery” address is 

192.168.178.49 

This (default) setting will already match if you use the “Fritz Fon” device of AVM company 

as internet router. Meanwhile this device is offered quite often in connection with DSL flat 

rates at an advantageous price and offers an excellent price/performance ratio. In this 

case you will not have to configure the IP address but you can immediately go to the next 

chapter „Connection to the inverter“. 

However, in all other cases, as your PC network differs from this address, the IP address 

of the SolarLog 400 will have to be set to an unallocated address of your PC network. 

This is quite easily done with the SolarLog 400e as we have integrated a special mode for 

network detection in this device: the network search mode. 

Before switching on the SolarLog please hold the multi-function key (see as well page 

71) pressed with a sharp object. Now switch on the SolarLog and wait for about 20 

seconds - keeping the key pressed - until the status1-LED starts flashing. Now you can let 

go. By several times pressing the key you jump to the respective next mode. Thus, pay 

attention that only status1 flashes. (The other modes are explained on page 71). Now 

again press the key for about 5 seconds until the flashing stops. Now status1 is lighted. 

The SolarLog 400e now is in the network search mode, “listening” to any arriving data 

packets in order to determine the local network area. To facilitate the search, shut your PC 

down and reboot it again. During restart your PC sends data packets which tell the 

SolarLog the currently valid network area. 

As soon as the SolarLog is able to determine the network area, status1 will go to “off” and 

the SolarLog reboots - this time with a changed network address. 


The SolarLog has now converted independently (in our example) to the network address 

10.31.1.49 

and is now accessible with this network address. 

Note: The network search mode automatically determines the first three figures of a 

network address and then always allocates “49“ (fixed) as the fourth figure. In some rare 

cases this may lead to a double allocation with other network appliances which are also 

configured to „49“. Please make sure that the “49“ address is not allocated already in your 

network - at least as long as you have not switched the SolarLog manually to another 

address. 

If you don’t have available an internet router the network configuration is now complete 

and you can continue with section „Connection to the inverter“. 

Otherwise you will now have to save the network address of your internet router in the 

SolarLog network configuration. 

Start your internet browser now and enter the following in the address bar: 

[ip-address of SolarLog 400e ]/lan 

10.31.1.49/lan 

The configuration dialogue of the SolarLog 400e will open: 

At “Gateway“ now enter the network address which you have written down in step 1 of the 

configuration at “standard gateway. 

Generally, the input field “Subnet mask“ may remain unchanged, however, here as well 

you should enter the same sequence of numbers which you have written down in step 1. 


Of course you may now allocate a different network (IP) address to the SolarLog which 

differs from “49“. However, unless necessary, we recommend not to change anything. 

Now press the “Save” button and the network configuration is completed. All network 

settings will become effective only after restart of the SolarLog. 

Note: 

Unless the inverters have been detected and/or configured, the dialogues under System 

Supervision and Diagnosis cannot yet be used. 


Connection to the inverter 

Please take care that there is not yet any power supply to the SolarLog 400e , i.e. that it is 

switched off. 

The SolarLog 400e is designed for operation independently of the manufacturer which means 

that inverters of different manufacturers may be connected. 

Continue with the description valid for you. 

SMA – SunnyBoy/SunnyMiniCentral with RS485-PiggyBack 

Important note: Never open the casing of the inverter when it is energized/live. It is 

imperative to respect the advice and instructions of the SMA manual. 

Please stick to the following work order when installing the SolarLog 400e with the inverters: 

1. De-energize the inverters or wait for the evening 

2. Carry out all the cabling and installation work, however – do not yet connect the 

SolarLog 400e 

3. Connect the inverters to the mains supply and wait until all inverters are feeding in 

4. Connect the SolarLog 400e 

Before you can connect the SolarLog 400e to the inverter, a RS485 interface PCB, a socalled 

„PiggyBack“ needs to be mounted. 

For the use in SMA inverters two different PiggyBacks are suitable: 

− RS485-PiggyBack of Solare Datensysteme company (art. n°220020) 

− RS485-PiggyBack of SMA company (SMA art. n° 485PB-NR) 

Both PiggyBack types can be integrated without any restriction in all SMA inverters of the 

type „SunnyBoy“ or „Sunny Mini Central“, however, they have got different cabling. 

Installation of PiggyBack Solare Datensysteme 

The integration of the interface card and the cabling of the inverters is described in detail 

on page 66. 

Installation of PiggyBack-SMA 

The integration is described quite in detail in the SMA manual which is enclosed to the 

interface board. Cabling among the inverters is described on page “6 of 8“ under “Cabling 

of a SB / SWR via RS485 to a PC“. Connect the individual inverters, as described in the 

SMA manual, with a shielded 3-pole data cable. 

Then set the jumper A at the PiggyBack of the last inverter as described on pages “5 of 8“ 

and “6 of 8“ in the SMA manual. 

You may connect the SolarLog with the first inverter either with the data cable enclosed or 

with your own cable. 

Pull the vacant conductors through the cable opening of the inverter and connect

Brown(4) 7 

Caution! Only connect the SolarLog 400e to the power supply when all inverters are feeding 

in. Otherwise the system won’t detect all inverters. 

Now the SolarLog 400e reads the configuration data from the inverters. This process takes a 

couple of minutes depending on the number of inverters. During this period the status- 

LED-1 is off and status-LED-2 flashes. The recording of data will then start immediately. 

(In case not all inverters have been detected, the detection process can be restarted via 

the SolarLog menu item „Identify new inverters“– see page 55) 

Sunways – NT with RS485 interface 


imperative to respect the advice and instructions of the Sunways manual. 

Pay attention that each Sunways NT inverter must be configured with a different internal 

address. The factory setting is always address 1. The Sunways manual describes how to 

configure the addresses which can be done via the operating display of the inverter. It is 

recommended to determine the addresses successively starting from 1, i. e. 1, 2, 3 and so 

on.

Terminal strip 750V – models: 

Terminal strip 850V – models: 


Now connect the individual inverters with each other via the RS485 terminal strips using 

shielded 2-pole data cables as described in the Sunways manual. The RS485 each are 

executed as double connectors which allow to continue the cabling.

White (1) RS485+ 

Brown(4) RS485- 

The jumper JP400e must be placed at the inverter farest from the SolarLog, all other 

inverters must not be placed with this jumper. 

Note: Only plug in the green terminal-strip plug to the SolarLog 400e once all inverters are in 

operation. Otherwise the system won’t detect all inverters. 

Now the SolarLog 400e identifies all inverters in turn. This process will take some minutes. 

During this period, the status LED 1 is off and status LED 2 flashes. Then the data 

recording will start immediately. 



Kaco – Powador / PVI-BluePlanet with RS485 interface 


imperative to respect the advice and instructions of the Kaco manual. 

Powador 

All Powador models are delivered ex works with an integrated RS485 interface. However, 

the interface will have to be activated via the operating display. In addition, you will have to 

allocate a unique communication address to each inverter. It is recommended to 

determine the addresses successively starting with 1, i.e. 1, 2, 3 and so on. This setting as 

well is done via the operating display. Please follow the instructions given in the Kaco 

manual. 


PVI-BluePlanet 

The PVI-BluePlanet models were delivered until approx. mid of 2005 and either equipped 

ex works with an optional RS232 or RS485. For the operation with the SolarLog 400e the 

RS485 option is compulsory. Retrofitting of the interface is possible via Kaco company. 

Please ask your installer or directly contact Kaco. 

You will have to allocate a unique communication address to each inverter. The allocation 

is done via a DIP switch inside the inverter. Please follow the instructions given in the 

Kaco manual. It is recommended to determine the addresses successively starting with 0, 

i.e. 0, 1, 2 and so on. 

Note: If there is no DIP switch on the control PCB then this PVI-BluePlanet inverter is 

equipped with the RS232 version. 

Cabling/wiring 

The individual inverters are cabled via terminal strips inside the device. 


1. De-energize the inverters or wait for the evening (However, the input via the 

display must be executed during the day in case of the Powador models.) 





Terminal strip – Powador models: 

Terminal strip – PVI-BluePlanet models: 


Now connect the individual inverters with each other via the RS485 terminal strips using 

shielded 2-pole data cables as described in the Kaco manual. The RS485 each are 

executed as double connections which allow to continue with the cabling. To do so, 

connect the terminal A to the terminal A of the next inverter respectively and proceed 

correspondingly with terminals B. 




SolarLog to terminal strip in the inverter 

White (1) B 

Brown(4) A 

In addition, a terminal resistor of 330Ohm (attached to inverter) must be placed at the 

terminal strip of the inverter farest from the SolarLog. The terminal resistor connects the 

free terminal A with terminal B. 

Note: If the cable lengths are quite short, you may possibly do without terminal resistor. 

Note: Only plug in the green terminal-strip plug to the SolarLog 400e once all inverters are in 

operation. Otherwise the system won’t detect all inverters. 






SolarMax – Serie C and E with RS485 interface 


imperative to respect the advice and instructions of the SolarMax manual. 

C-Series 

With all C-series models the RS485 interface is already integrated ex works. You will have 

to allocate a unique communication address to each inverter. It is recommended to 

allocate the addresses successively starting with 1, i.e. 1, 2, 3 and so on. This setting is 

also done via the operating display. Please follow the instructions given in the SolarMax 

manual. 

E-series 

The E-series models are not equipped with a communication interface in their standard 

version. Thus they need to be retrofitted with an appropriate interface prior to connecting 

them to the SolarLog. 

Please follow the installation instructions attached to that interface. Especially consider the 

correct setting of the RS485/RS232 jumper and of the terminal resistor on the interface 

card (see manual for interface card). 


You will have to allocate a unique communication address to each inverter. It is 

recommended to determine the addresses successively starting with 1, i.e. 1, 2, 3 and so 

on. This setting as well is done at the operating display. Please follow the instructions 

given in the SolarMax manual. 

Cabling 

The individual inverters are cabled with each other using conventional network cables 

equipped with an RJ45 plug. 


SolarMax C series: 

1. Cabling may be done at any time because it is not necessary to open the inverters. 

2. Carry out the entire cabling and installation – however, do not yet connect the 

SolarLog 400e to the green terminal strip plugs of the enclosed data cable 

3. Connect the SolarLog 400e as soon as all inverters are feeding in 

SolarMax E series: 


display required to set the communication address must be executed during the day.) 





Connect all SolarMax inverters with each other via conventional network cables. 

SolarMax C series: 

On the bottom of the device you will find the two RJ45 jacks for system communication. 

Plug in one of the cable plugs in any jack of the first inverter. Take the other plug of the 

cable and plug it in any connector of the second inverter. In the same way connect the 

inverter n° 2 with inverter n° 3 etc. 

The RJ45 plug of the enclosed data cable of the SolarLog is then plugged to the vacant 

connector of the last inverter. 

SolarMax E series: 

As the RJ45 connector jacks are inside the inverter at the interface card, the network 

cables must be fed through the cable bushing at the bottom of the device. Except for the 

first inverter, always two cables are passed through the bushing: One cable from the 

previous inverter and one cable to the next inverter or to the SolarLog. Plug the cable of 

the previous inverter to the left jack with the inscription „RS-485 in“ and the cable to the 

next inverter to the right jack with the inscription „RS-485 out“. 

Now plug the data cable with the RJ45 plug (enclosed to the SolarLog) into the last 

inverter.. 

Note: Only insert the green terminal block plug to the SolarLog 400e if all inverters are 

operating. Otherwise the system won’t detect all inverters 







Fronius – IG15-60 with ComCard 


imperative to respect the advice and instructions of the Fronius manual. 




SolarLog 400e 



Before connecting the SolarLog 400e to the inverter, an interface PCB - a so called 

„ComCard“ - needs to be installed. 

Installation Fronius-ComCard 

The ComCard may optionally already be installed ex works or may be retrofitted as 

„ComCard retrofit“. 

Note: The inverter must be opened for the installation work. Please absolutely follow the 

prescriptions given in the Fronius-IG manual of your inverter! 

The installation of the ComCard is described in great detail in the inverter manual, please 

follow all instructions. 

We recommend leaving vacant one connector place between the installed ENS card and 

the ComCard. 

Communication address 

You will have to allocate a unique communication address to each inverter. We 

recommend allocating the addresses successively starting with 1, i.e. 1, 2, 3 and so on. 

This setting is carried out at the operating display.. Please follow the instructions given in 

the Fronius manual, chapter “Operating concept“, section “Setup menu“. 

Cabling 

The individual inverters are cabled with each other with conventional network cables 

equipped with an RJ45 plug.. 

Each ComCard has got two RJ45 jacks marked with “IN“ and “OUT“ respectively. It is key 

to observe the correct cabling order as otherwise there will not be any data exchange. 

Caution! The SolarLog is as well equipped with a RJ45 jack. By no means this jack must 

be connected to the RJ45 socket of the inverters. This could destroy the SolarLog! 


Now cable the SolarLog, the interface converter and the inverters according to the 

following diagram:

respectively, etc. 

6. Insert the terminal connector into the OUT jack of the last inverter. 

7. Connect the converter with the small enclosed connector type power supply unit. 

Caution! Only insert the 9-pole data cable into the SolarLog if all inverters feed in. 

Otherwise the system won’t detect all inverters. 

Note: LED-E at the SolarLog indicates the communication status. As soon as all cables 

are correctly inserted and all inverters are active, the red LED switches off.

RS485 interface 

For data monitoring with the SolarLog an RS485 interface is required. As of 02/2007 this 

interface has already been factory-mounted in all inverters. Previously delivered models 

were either equipped with RS485 or with a wireless interface. However, you cannot use 

the wireless interface for the SolarLog. In this case the RS485 interface needs to be 

retrofitted by your qualified solar installer. 

No further settings at the inverter display are required. 

Cabling 

The individual inverters are cabled with each other with conventional network cables 

equipped with an RJ45 connector. The two RJ45 jacks are at the right side in the lateral 

cover panel which can be screwed off. Please consider the instructions given in the

On the bottom of the device you will find the two RJ45 jacks for system communication. 

Plug in one of the cable plugs in any jack of the first inverter. Take the other plug of the 

cable and plug it in any connector of the second inverter. In the same way connect the

Power-One/Aurora with RS485 interface 


imperative to respect the advice and instructions of the Power-One manual. 

All Power-One inverters are equipped with an RS485 interface ex works. In addition, a 

unique communication address must be allocated to each inverter. We recommend to 

allocate the addresses successively starting with 2 (not 1!), i.e. 2, 3, 4 etc. This setting as 

well is done at the operation display. Please follow the instructions given in the Power- 

One/Aurora manual. 


Cabling 

Cabling of the individual inverters is done via terminal strips inside the device. In case of 

the indoor/outdoor models, there are sometimes integrated different interfaces. In the 

following we will go into details about the cabling with RS485. 



display must be executed during the day.) 



Connect the inverters to the mains supply and wait until all inverters are feeding in 

Connect the SolarLog 400e 

Terminal strip – Outdoor models: 

As described in the inverter manual, connect the individual inverters with each other via 

the RS485 terminal strips using a screened 3-pole data cable. Connect terminal “+T/R“ 

with terminal “+T/R“ of the following inverter respectively and the terminals “-T/R“ and 

“RTN“ correspondingly. 

For the connection of the SolarLog with the first inverter you may either use the data cable 

enclosed or your own cable. 



White (1) +T/R 

Brown(4) -T/R 

Green (3) RTN 

In addition, the terminal resistor must be placed at the inverter farest from the SolarLog. To 

do so, the small switch must be turned to position “ON“. 









Mitsubishi with RS485 interface 


imperative to respect the advice and instructions of the Mitsubishi manual. 

All Mitsubishi inverters are factory-equipped with the RS485 interface. In addition, a unique 

communication address must be allocated to each inverter. We recommend to allocate the 

addresses successively starting with 1, i.e. 1, 2, 3 and so on. This setting is carried out at 

the operating display. Please follow the instructions given in the Mitsubishi manual. 

(Address number 1 is preset at all Mitsubishi inverters). 

Cabling 

Cabling of the individual inverters is done using conventional phone cables equipped with 

an RJ11 connector which is always of the 6-pole type. Normally however, only the 4 centre 

pins are used which is totally sufficient. The important thing is that the 4 (or 6) pins are 

looped through 1 to 1. 

The two RJ11 jacks are on the bottom left inside the inverter. For installation it is 

necessary to screw off the front panel of the inverter. Please observe the instructions given 

in the Mitsubishi manual. 

Now connect all inverters with each other using the RJ11 cables. 

Insert the cable connector in any one jack of the first inverter. Insert the other connector of 

the cable into any one jack of the second inverter. Proceed in the same way to connect the 


Insert the data cable with the RJ11 connector enclosed to the SolarLog to the still vacant 

jack of the first inverter.

System supervision 

There are various options to visualise the yield data. The data may be displayed in a fullscreen 

view or alternatively in a small view especially developed for PDAs. Furthermore, 

all data may be transferred to an Internet homepage allowing remote enquiries. 

In each view you will have the choice between daily, monthly and annual overview, partly 

this choice is available in a general overview on all years which have been saved. 

There is always the option to select previous periods (e. g. day before or previous month) 

via the respective arrow symbols “Forward“/“Back“. 

Supervision PC 

This standard view will open in a separate window and contains 

− daily overview 

− monthly overview 

− annual overview 

− general overview 

Daily overview 

The programme always starts with the current date of the day in daily view. With the arrow 

symbols top left you may select various days in retrospective. 

The daily yield curve is composed of averaged 5 minute values. 


Depending on the number of connected inverters (max. 20) the respective number of 

inverter symbols will appear. The symbol at the very left stands for all inverters, the 

symbols right of it stand for an individual inverter respectively. The symbol’s colours solely 

serve to distinguish the single inverters. Each symbol may be selected separately and it is 

possible to combine several or all with each other. A symbol with a „tick“ means that the 

yield information of the desired inverter is displayed. If only one single inverter is ticked, 

this inverter is shown with all available string information. Of course this will only work if 

this inverter is a multi-string model. 

The yield curve of all inverters as a whole or of only one single inverter is shown as a 

yellow area. Secondary information, i.e. information about individual inverters or on single 

strings, is shown in coloured lines. 

The Y-scale results automatically from the inverters selected and is determined based on 

the maximum performance from the inverter configuration. 

Via the control buttons on the right you may have shown additional information, if needed. 

Yield: Here, the yield line is shown. It indicates the current accumulated daily total. In 

addition, a green line exhibits the targeted daily total. 

Udc: Shows the generator voltage. In order to display the voltage of the individual 

strings only 1 inverter must be selected. 

kWp: This allows to switch the scale on the left from “output in Watt“ to “output in 

kW/kWp“, i.e. the output value of a string and/or inverter is divided by the 

connected generator output. Thus, all curves become comparable as to their 

specific output and the output/performance can be visually checked. Strings with 

the same module orientation and the same slope must “overlap”, i.e. be lying upon 

each other. If not, we most often find there a shading, however, it may as well 

indicate an installation fault, e.g. the connection of a module has been “forgotten” 

or has been connected to a wrong string. Decreasing module outputs may be 

detected, too. 

°C: Here, the internal inverter temperature is displayed. Especially with devices 

equipped with a fan it is possible to indirectly determine whether the fan still works 

correctly and discharges the hot air to the outside. Please take into account that 

inverters are designed for high internal temperatures. The temperature is only 

displayed with inverters delivering the respective measuring value (e. g. not with 

SMA and Fronius). 

The table below the graph always displays the current values on the left side. On the right 

side, however, the values specific of the day are shown: 

Designation Unit Description 

Power input Pac W Currently fed-in power P at AC voltage end 

Generator power Pdc W Currently fed in power P at DC voltage end (=Solar 

generator). In case only one single multi-string inverter is 

selected, the individual strings are shown separately 

Inverter efficiency η % The current efficiency 'eta' derived from generator power 

and power input. The manufacturer’s indications as to 

the efficiency of the inverter can be checked here. 

Status / Error Status code and - depending on the inverter – 

failure/error code. The shown codes depend on the 

manufacturer and must be looked up in the respective 

inverter manual. 

Identical status messages will always be summarised. If

all inverters are in Mpp mode, “Mpp“ is displayed. If, 

however, one inverter is in the derating mode, the 

following would be displayed: “2xMpp, 1xDerating“ 

Daily yield Euro Total of the day multiplied with the feed-in 

reimbursement. 

Daily yield, specific kWhp Total of the day divided by the system size. This value is 

very good for comparison with other systems. 

Maximum value W Maximum output value within one day. 

Target kWh The SolarLog 400e keeps forecast statistics which 

prescribes a certain target value for each month. The 

monthly target here is converted into a daily target and 

then displayed. If the target value is reached or 

exceeded by the actual daily yield, then the forecasted 

output has been met. 

Actual % The actual value shows the percentage ratio between 

daily actual yield and daily target yield. 

*Only the selected inverters are totalled and/or displayed. 

Monthly overview 


The operating corresponds to the daily view. Via the menu items on the left you can select 

other periods, via the arrow symbols you can scroll always one month ahead or back. With 

the inverter symbols you can display the daily yields on a pro rata basis as a bar chart. 

The individual daily yields are shown as total sums in a bar chart. If you click to an 

individual bar, the programme returns to the daily view of the respective day. Depending 

on whether the current (momentary) values of this day are still in the memory, the curve of 

the course of the day is displayed. 

The green line shows the target yield of the day. 

The table below the diagram shows the current (momentary) values on the left side. On 

the right side, however, the values specific of the month are shown:

Target kWh The SolarLog 400e keeps forecast statistics which 

prescribes a certain target value for each month. If this 

target value is reached or exceeded by the actual 

monthly yield, then the forecasted output has been met. 

Please note that the monthly target value is calculated 

on a pro-rata basis using the exact days. On the first day 

of the month, the monthly target is = monthly target/n° of 

days per month 

Actual % The actual value shows the percentage ratio between 

monthly actual yield and monthly target yield.

Annual overview 

The operating corresponds to the monthly view. Via the menu items on the left you can 

select other periods, via the arrow symbols you can scroll always one year ahead or back. 

The individual monthly yields are shown as total sums in a bar chart. The green line shows 

the requested target yield of the month. 

If you click to an individual bar, the programme returns to the monthly view of the 

respective date. The system offers daily dates of the past three years.

Target kWh This configuration allows to fix a desired annual target 

which is then displayed here. In the current year a target 

value is shown up to the current day date 

(„accumulated“). 

Actual % The actual value in percent shows the ratio between 

annual actual yield and annual target yield. 

It may well be that the actual value already exceeds 

100% although the current year is not yet over. This is to 

say that the amount in brackets has already been 

reached even in case only daily yields will be generated 

which are in the debit range. In the aforesaid example, 

the annual forecast is 992 kWhPeak even if November 

and December only show average values.

Supervision Palm / PocketPC 

This view has been especially designed to be displayed on the small screens of portable 

PDAs and to suitability in the living space. 

Resolution is 320x320 pixels. 

The view is compatible with Palm OS5 and higher as well as with PocketPC-2003/2005 

using the open-source programme “Minimo“ or the browser “Opera“ (recommended). 

Note: The PDA presentation and design has been successfully tested, among others, with 

“Palm Tungsten C“ and „HP HX4700“ (PocketPC) 


On the PC, however, this view is an alternative as well as this window can “run” along one 

side of the screen frame and is automatically updated every 60 seconds. Thus, you can 

always monitor your system. 

Daily view 

The accumulated daily output curve of all inverters is presented in averaged 5-minute 

values. The PDA view does not show any string data. To do so, you will have to call up the

Diagnosis 

The main task of the SolarLog 400e is the early detection of system problems. Apart from the 

automatic alarm messages via e-mail and SMS, the SolarLog 400e offers the additional 

diagnosis features under this menue item. This features are available at any time. 

Event Log 

The SolarLog 400e individually monitors and analyses each and any inverter connected. This 

implies as well the permanent readout of the internal status and error codes. These codes 

may differ from one inverter to the other; they are explained in the inverter manuals. 

Note SMA-codes: The designations shown in the SolarLog are always original SMA- 

designations. The major part of them is explained in the SMA inverter manual. 

Each change in status and error codes will be exactly logged in the event log. It records as 

well the off-line periods, i.e. the periods during which the inverter is switched off. 

We recommend to regularly check the event log for irregularities. 

Possible irregularities : 

− power mains disconnection during the day 

− frequent derating of an inverter. In this case, the inverter steps down (derates) the fedin 

power due to overload or excessive operating temperatures. 

However, it is absolutely normal to find the status repetitively changing in the morning or in 

the evening, i.e. when the inverter leaves its „night phase” or again enters into the switchoff 

phase. 

The event log is prepared in form of a table which always shows all current records. The 

log offers a capacity of 400 events. 


Degradation 

In the course of the years, the solar modules „age“, i.e. their yield gradually decreases 

even with the same solar radiation available. 

The module manufacturers grant output warranties normally they guarantee rated outputs 

of 80% for 20 to 25 years. However, how to compare and evaluate the module output over 

the course of the years? As a matter of fact, every year offers different climatic conditions 

and is hardly comparable to another. 

Here the SolarLog 400e offers a statistical evaluation of each individual year based on the 

daily records. 

It calculates the average daily maximum value for each year. 

This average value is calculated from the actual maximum values corrected by a statistical 

approximation to filter extreme peaks. 

The comparison of the calculated maximum values provides an indication on the system 

performance. Of course data comparison requires a sufficient number of data records per 

year as well as identical system technology and components. The days in spring and 

summer are especially important for the comparison because here we will get the 

maximum yields. 



Configuration 

The configuration serves to optimally match the SolarLog 400e to your demands and 

requirements. 

The SolarLog 400e has got two operating modes: 

1. Online mode – The inverter delivers data (day operation) 

2. Offline mode – The inverter does not deliver any data (night operation) 

During online operation, i. e. during the day, the configuration dialogues are blocked. 

Configuration is only possible in the offline mode which may be manually activated in the 

main menu, if need be. In this case the SolarLog will be in the offline mode for about 5 

minutes and then it will automatically switch back to online mode. 

If you call a configuration dialogue, this offline period will be prolonged by another 5 

minutes. 

Basic Configuration 

The basic configuration comprises the major settings. These settings normally do to 

operate the device without an Internet connection. 

LAN - Settings 


We have already dealt with the network settings in the chapter „Installation Instructions“, 

the settings executed according to these instructions do not require any change under 

normal conditions. 

However, a modification will always be necessary if the network addresses are changed to 

other areas. Please remember to convert the SolarLog 400e in due time to the new network 

address. 

Internet access 

Please adjust here how the SolarLog 400e is connected to the Internet. 

Inverter 

In this dialogue you can save all data relevant to the inverters. With SMA/Kyocera devices, 

the appliance designation and the serial number are automatically read out. For the 

inverters of other manufacturers the communication address will be shown. 

Please check that all inverters have been correctly recognized. Every inverter is uniquely 

identified by its serial number. 

The inverters are always indicated sorted according to the serial number or the 

communication address. With a classification according to the serial number (SMA) the 

inverter position may be changed to another number by using the field “new number”. This 


allows to easily set the desired inverter order. However, the order will have to be fixed 

immediately after the inverter recognition. 

Installed Generator Power 

This is the module output in Wp connected to the inverter. The overall output (power) is 

calculated based on the module output x number of modules (in total at the single inverter, 

not the overall system). 

Pac Correction factor 

When comparing the power yield indicated by the inverter with the values indicated by a 

calibrated current meter, we will find a deviation. Either the inverter indication is too high or 

too low. In order to at least roughly compensate for this inaccuracy, it is possible to define 

here a correction factor. 


Internally all yield data are always saved without any correction factor. This factor is only 

applied at the moment of data output. Thus it is always possible to adjust this factor at a 

later date. 

The formula to calculate the correction factor is: 

yield current meter / yield inverter * 1000 

If the inverter is not equipped with a display, a correction factor of 1000 will have to be kept 

first at to be able to determine a factor after about one week. 

Initial nominal output 

Please indicate here the nominal inverter output. You will find these data in the operating 

manual of your inverter. It is used for later diagnosis calculations and is not important now. 

Identification 

Short description of the inverter, in case of Non-Multi-String-Inverters may be the position 

of the connected modules. 

Supervision 

An important function of the SolarLog 400e is the monitoring of the single inverters, their 

strings and the connected modules. Malfunctions may be indicated via e-mail and SMS. 

The following will be monitored and detected: 

− inverter failure 

− power or output decrease of a module field 

The monitoring is based on the permanent output comparison of all inverters including the 

individual strings in case of Multi-String-Inverters. In case the target output deviates from 

the actual output (taking into account a defined tolerance) then the system may trigger a 

fault message after a selectable delay. 

Every connected string is assigned to a module field. The module fields are divided 

according to same solar module type, module inclination and orientation. If, within one 

system, all modules are of the same type with the same orientation, then only a single 

module field will be defined, for example “1”. Non-assigned (vacant) strings must be 

switched off with “0”. In case of different orientations additional module fields must be 

defined. 

In the ideal case, each field is made up of at least two individual strings monitoring each 

other. 

Example: 

A system with 23.6 kWp is divided into 3xSMA SB5000TL, 2xSMA SB2500, thereof 18 

kWp with 30° inclination on the roof of a barn, 20° SE-deviation and on an adjacent garage 

5 kWp floor-mounted 32° inclination, 0° south deviation. 


Location Inverter String Output Module field 

Barn 1.SB5000TL 2000 1 

Barn 1.SB5000TL 2000 1 

Barn 1.SB5000TL 2200 1 

Barn 2.SB5000TL 2000 1 

Barn 2.SB5000TL 2000 1 

Barn 2.SB5000TL 2200 1 

Barn 3.SB5000TL 2000 1 

Barn 3.SB5000TL 2000 1 

Barn 3.SB5000TL 2200 1 

Garage 1.SB2500 2500 2 

Garage 2.SB2500 2500 2 

All connected strings can be monitored by each other, the strings belonging to module field 

1 through several strings, and for module field 2 both strings reciprocally. 

If the output of the single module decreases, the string output will decrease as well with 

still the same radiation, this decrease will be detected and reported. 

This output or power comparison is always reliable – even in case of clouds. However, it is 

important that there is no shadowing on the modules. Therefore, in configuration, it is 

possible to define a monitoring period during which any shadowing can be reliably ruled 

out. Considering that the power measuring inside the inverter becomes rather inexact 

below a defined threshold value, you may as well fix a minimum percentage below which 

monitoring will be suspended. 

Unfortunately there may as well be fault reports or messages when the modules are 

covered by snow. These messages or report result from the output comparison and occur 

in case of partial coverage or failure messages due to the complete snow cover which 

causes the inverter not to switch on at all. 

There are two possible procedures to minimize this problem: 

1. The minimum percentage at which output monitoring will start should be as high as 

possible, for example 30 %. With a generator power of 4500 Wp the monitoring will 

start only at 1350 W. However, the power of the unshadowed modules is reduced 

by partially shaded modules such that we rarely or never achieve the required 1350 

W. In this case the problem of partial covering has been solved. 

2. The system will always produce failure messages, if the inverter does not work / is 

not online, during the period of time set as unshadowed. The system assumes that 

there is a defect. Thus, a complete snow cover would be indicated as well as a 

failure. To solve this problem, the system contains an indicator for snow covering. If 

this indicator has been activated, there won’t be any failure message if all inverters 

are off line. It may happen that all installed inverters are defective ( for example in 

case of a lightning stroke ). However, this is rather unlikely. If the indicator is 

activated, the system will assume that the inverters do not work because the 

modules are completely covered by snow. In addition, this indicator depends on the 

actual date: it will be taken into account only from the beginning of November till the 


end of April. Apart from this period, i.e. in spring, summer and autumn, the indicator 

is automatically deactivated. The monitoring will work then as usual and will report 

as well the complete failure of all inverters. 

The duration of the error or failure indicates how long a failure or error must permanently 

exist to be recognized as “error” by the system. The minimum error duration is 5 minutes. 

However, a longer period should be selected. 

To avoid an excessive reporting of the occuring failures or errors it is possible to define a 

maximum number of messages per day. 

Graph Scaling 

In the normal case it is not necessary to change these settings because the SolarLog 

automatically calculates the values when the generator power is entered. However, you 

can adapt these values to your own requirements. 

For each period (value of the day, the month, the year, total) you can enter the maximum 

value to be reached in kW (except for day). 

Forecast 

The forecast serves to get an idea whether the system will reach the desired annual yield 

or not already in the course of the current year. 

For this purpose each month will be allocated a percentage by share calculated based on 

the German yield statistic of the past few years. 


Of course we never know exactly how the summer will be and whether a month will be 

completely „corrupted“. However, the annual forecast is normally rather precise and 

reliable already in September. 

The SolarLog 400e calculates the target value always accumulated to the exact day. Thus, it 

will not request the entire monthly target yield already at the beginning of the month but 

only the already past days of the month including the current day. In the forecast the 

SolarLog includes as well the yields reached in the previous years and thus is able to allow 

for local weather (for example: biggest amount of snow in December). 

Installation size 

Please indicate the installation size in WattPeak. 

Feed-in tariff 

Please enter here the feed-in tariff valid for you. With this factor the yield will be calculated 

in Euro in the supervision mode. 

Annual target value 

Enter here the desired annual target value in kWh/kWp. 

Monthly Shares 

The monthly shares must reach a total of 100 %. If not, you can adapt the values to the 

local conditions. However, it is normally not necessary to change here anything. 

Graph 


The graph view is determined by the scaling of the X- and Y-axis. 

On the X- axis you will find the course in time, on the Y- axis you will find the measured 

value. 

For the day view it is necessary to define the start and the end of the day for every month 

in order to prevent that the data start or end will be lost in the graph. 

Advice: The SolarLog 400e operates independently of this configuration and it gathers the 

data as soon as the inverter provides them and it stops as soon as the inverter switches to 

night shut-down. 

Thus, the two top input lines are always assigned to start of the day and the two data lines 

at the bottom are always assigned to end of the day. 

Normally no modification is required here. 

Expert Mode 

Under „configuration expert“ you will find in particular those functions related to the 

internet. Thus, if the SolarLog 400e is not connected via an Internet router, you may skip this 

configuration item. 

However, we recommend to connect the SolarLog to the internet to ensure at least the 

automatic messaging via Email/SMS. The hardware cost expenditure for an analogous 

router will be less than 100 EUR. It is possible to use an analogous router as well with 


ISDN telephone systems because these systems always offer as well an analogous 

telephone extension. There will only be log-on fees in case of a failure. These costs will be 

for example with www.arcor.de about 1 Cent per minute, without any contractual 

obligation. 


Internet 

Via this dialogue, configuration of the data contained in the homepage view is possible. In 

addition, it is possible to customize the online banner with text at your discretion. 

For more information see chapter „Homepage“ 


Email 

In the SolarLog 400e there is an email programme which allows to send messages in defined 

situations upon request. These messages are: 

− overview daily yield 

− inverter malfunctions 

− inverter failure 

− deviation of target outputs 

On the one hand, the settings contained in this dialogue serve as a basic configuration for 

the general sending of emails, and on the other hand, they serve as a configuration of 

whether and when the daily yield shall be sent out as an information. 

Even if you do not wish to have the daily yields sent out as an information, it will be 

necessary to save here the email server data and to get for example mails on error / failure 

messages. 

You will find the „SMTP-Server“, „login“ und „password“ in the documentation of your 

internet / email provider. 

Advice: You can request free of charge a homepage and email address under 

www.solarlog-home.de. As soon as the connection is cleared, you will get an instruction 

for setting up the login details. 


If you use your own email server, then „email from“ and „email to“ will be identical, i.e. your 

own email address. 

„Last transmission“ and „status“ indicate, when the SolarLog 400e last tried to send an email. 

Possible status codes: 

1 – Timeout, no „Connect“ to SMTP-Server possible. Is this the right serveraddress? 

2 – Invalid email-address, the „@“ is missing 

3 – Authorisation log is not supported by SMTP-Server SolarLog 400e supports 

AUTH-PLAIN and AUTH-LOGIN) 

4 – Login or password not accepted 

5 – Email may be sent out, but log not correctly closed 

You can test the sending out of emails directly during the configuration with the button 

„start test transmission“. Before doing so, please save the modified settings. 

SMS 


The SMS messaging is done in two steps. First of all, an email is sent to an email provider, 

offering a SMS service. Through a keyword written in the subject line the provider 

recognizes that this email shall be transmitted as an SMS to a designated number. 

The following email providers, among others, offer this service: „T-Online“, „Arcor“ and 

„GMX“. 

„Earning in subject heading“ (earning = yield) indicates that the SMS text is in addition 

written into the subject heading. In case of emails received some email providers send out 

free of charge an SMS with de subject headline for information. This will already do to get 

an idea of the system at convenient cost. 

For further configuration, see „email“. 

The configuration will be extremely easy if you use the SMS service of www.solarloghome.de. 

You can test the SMS messaging directly during the configuration by using the button 

„start test transmission“. Before doing so please save the modified settings. 

Export 


Export serves to regularly transfer the yield data to a homepage and thus to be able to 

present the system including the online data in the internet. 

Modify the examples given and enteri your own data. 

Under „FTP server“ you will normally enter the name of the homepage. 

„Login“ and „Password“ are the login data to the homepage. 

It will only be necessary to make an entry under „directory“ if the SolarLog homepage is 

not assumed to be directly shown in the main directory on your homepage. Otherwise, this 

field may stay blank. 

The update interval determines how often the SolarLog 400e transfers the data. It will always 

copy all the 5-minutes-data not yet sent out even if the interval is by far longer, for example 

an hour. Depending on the internet tariff you can choose here indirectly the desired 

transmission volume. To give you a reference, it is assumed that a maximum of about 10 

Kbyte will be transferred with each transmission, this is not very much. 

If you want to “feed” the SolarLog homepage via this export, please select the „SolarLog“ 

data format. As an alternative or as well in addition you can choose the data export in the 

CSV format. In this case the files will be exported to the homepage in a format which is 

Excel readable. There you can use the data for additional evaluations, if need be. The 

export is done in the morning and in the evening (at the switching between online/offline) 

for all the saved data. In addition the 5-minutes-data are always saved with the date of the 

day, thus there will be set-up an archive containing already very old data which have been 

overwritten in the SolarLog 400e (-> circular buffer). 

Advice: The data transmission will not be realised immediately after the configuration, it 

may take about up to 12 hours to transfer all the data. The reason is that older data with a 

higher volume are only transferred when the inverter switches on and off (online/offline). 

To speed up this prodedure, just shortly switch on and off the SolarLog. After about 10 

minutes the data transmission will be executed. 

In case of problems with data transmission, you can check in the fields „last transmission“ 

and „status“ when the SolarLog 400e last tried to copy data. 

Possible status codes: 

1 – FTP-Server not found. Please check correct spelling 

2 – FTP-Server connected but no availability message received 

3 – Wrong user name 

4 – Wrong password or password not accepted 

5 – Unable to switch to the desired directory 

6 – Impossible to send file 

7 – Error at logout 

8 – IP address cannot be identified 

You can test the data sent out directly during configuration with the button „start test 

transmission“. Before doing so, please save the modified settings. 

Those who do not have an internet access via router, i.e. the SolarLog 400e is not equipped 

with an internet access, may as well export the data manually (in the CSV format) to the 

hard disk. 

Configuration will be very easy if you use the free of charge service under www.solarloghome.de. 


Malfunction 

With a certain status or error code, the SolarLog 400e can trigger a message via email or 

SMS. 

Via this dialogue you are free to set up as of which error duration a message shall be sent 

out for the status/error codes at your discretion. In addition, you can set the maximum 

number of messages to be sent out. This is to prevent that the system permanently sends 

out SMS due to minor system problems. 


It depends on the inverter type which status and error codes are available. In the inverter 

manual you will find information on which status and error codes are relevant for automatic 

messaging. As a default setting all error codes will be indicated (suitable for SMA). 

Status and error codes of the SolarMax inverter 

The field from 1 to 31 concerns error messages. 

The area from 32 to 49 concerns status messages. 

Internal 

The „Internal Configuration“ contains the items backup, system data import from the initial 

inventory and update of the SolarLog 400e software. 

Backup 


Backup - automatic 

Here a regular data backup on any homepage may be configured per FTP log. The 

backup includes all statistical data. As each transmission includes larger data volumes (>1 

Mbyte) the automatic backup must not be activated in case of analogous and mobile radio 

transmissions. 

Backup - manual 

If there is no access to the internet the backup may as well be realised manually. In this 

case a file will be saved directly in an optional directory on the PC. 

It is as well possible to reimport an old backup. This may becöme necessary for example 

in case of a software update. 

Correction of data 

Under this item it is possible to always correct the day total or enter it anew at a later date 

for each and any day. 

You will always have to enter the date as an 8-digit entry, i.e. two digits for the day, two for 

the month and two for the year – separated by a decimal point. 

The day value is entered in Wh, it must correspond to the current meter reading, i.e. 

correspond to the actual day value. 

Data import of old daily data 

It is as well possible to import the initial inventory of manually recorded daily data into the 

SolarLog 400e . This will always make sense if you intend to collect a large amount of data 

retroactively which will take too long with the function “correction of data”. 

The file must be composed of individual text lines in which a date of the day and the daily 

yield value „Wh“ must be separated by semicolon. 

Example: 

01.04.06;136435 

02.04.06;128219 

etc. 

Advice: Here, the year may be indicated as a 4-digit date. 

In case of a data import the available data storage is completely deleted before the daily 

data are imported. Therefore the data import should be realised immediately after the 

SolarLog start-up. 

The overall value of the day is divided on prorata basis according to the configured inverter 

output. Please keep in mind that the total of the configured inverter output corresponds to 

the value of the system overall output in configuration/basis dialogue. If not, the SolarLog 

will display deviating daily values after the data import. 

Please enter the current meter reading. The daily value will be corrected accordingly via 

the correction factor. In case the correction factor is not known at the beginning the value 

should be set to 1000. 


Data import will only be possible if all inverters have been correctly recognized and set up. 

Advice: Please check whether the data format meets the aforesaid requirements. To do 

so, start the programme „wordpad“ available under each and every Windows installation. 

Then you open the legacy data file to check the data format. At the beginning and at the 

end of the line there must not be any apostrophe. You may as well immediately correct the 

data file with Wordpad and then save it. 

System 


The „system data“ are all data stored by you in the configuration. Therefore we 

recommend a backup of system data each time you change the configuration. 

After a firmware update it is possible that all data have been initialised anew, i.e. they have 

been deleted. In this case your first task will be to import the system backup after the 

firmware update. 

If the inverter configuration at the system has been modified, for example a defective 

inverter has been replaced, you will have to inform the SolarLog and “introduce” it to this 

new device. To do so, use the function „Inverter scan/ New identify“. (You can call this 

function as well with the multi function key, see page 67.) 

In case of the SMA inverter, this function must always be used in case of replaced or new 

inverters! 

With inverters of other manufacturers the following applies: In case of a replacement, the 

communication address of the replacing device should always correspond to the address 

of the old device, then the new identification won’t be necessary. In case of an additional 

inverter the new identification will have to be started here as well. 

Via the item „reset to factory settings“ you can reset the SolarLog to its delivery state. 

(This function may as well be activated with the multi-function key, see page 71.) 

However, the network settings will not be reset, this is to say the IP address will remain 

unchanged. 

All configuration data, all the data already gathered and the inverter configuration will be 

deleted. As a result the SolarLog will try again to identify the inverters. This will be 

necessary if 

1. Not all inverters have been recognized at the initial installation 

2. If there have been subsequent changes in the inverter configuration. The system 

especially does not automatically identify additional inverters. This identification will 

only be done after the reset to factory settings. 

Attention! The SMA inverters are internally provided with their own independent 

configuration and own address. Thus every replaced inverter will have to be 

identified anew via an inverter identification and then adopted in the system. On the 

other hand, the inverters of Sunways, SolarMax, Fronius und Kaco have got a fix 

address allocation. The replacing devices must just be set to the address of the old 

device. 

Once the old data backup has been reimported, the system will automatically 

allocate the data of the former device to the replaceming device. 

Advice: Before a reset to factory settings we recommend to do a system and data backup. 

With both backups you will be able to provide the SolarLog 400e with the old settings and 

data if need be. 

The current serial number is the number permanently allocated to the SolarLog which can 

not be modified at all. 

The storing or backup interval is automatically preset based of the number of identified 

inverters. The SolarLog detects new measuring data every 15 seconds, these data are 

saved as an average in the fixed interval. If the interval is changed from 5 to 10 minutes, 

the number of minute values will double, thus the number of day curves will double as well. 

The larger this interval is the less detailed will be the graph. 


If a homepage is used for the graphic supervision (visualisation) you can set the 5 minutes 

interval as well with large-scale systems because the day curves will be stored for an 

unlimited period of time on the homepage. 

Date / Time 

The SolarLog400e is equipped with an integrated real-time clock operating for a long 

period of time (100 days) even in case of power failure or separation from the mains. 

If the system is connected to the internet, the clock will be readjusted every day. Thus it 

will never be necessary to manually adjust it. However, if a wrong date or time is indicated, 

it can be easily corrected or set anew. You just have to enter the desired day and time. 

Example: The entry for the 28.2.2007 5:31 p.m. would be: 28.02.07 17:31:00 

Automatic switching to summer time: thus it is not necessary to adjust it manually. 

Allow configuration only in your own LAN 

This item is only important in case of an existing internet access. Then you should tick this 

item in order to deny undesired access from the internet. 

Additional Password Request 

To deny undesired access to the configuration area you may save a password. This 

password will be requested at the first access to the configuration area. The SolarLog then 

releases the reading and modification within the configuration area. 5 minutes after the last 

configuration access the access will be blocked again. Then a new login in this area will be 

necessary. 

To change the password it is always necessary to enter the old password as a safety 

function. At the moment of delivery and after a reset to factory settings, there is no 

password stored in the system. In this case you do not have to enter anything under old 

password. 


Update 

Under this item the SolarLog 400e software may be updated. 

Thus it is always possible to incorporate new functions in the system or to eliminate errors. 

Before an update it is absolutely mandatory to make a system data and data backup. 

Depending on the update, a new organisation of the internal data structures may become 

necessary, as a result all data will be deleted. 

Therefore it is absolutely mandatory to save all data before!! 

You can call the latest updates at the internet site 

www.solare-datensysteme.de/firmware 


Homepage 

The SolarLog 400e offers another interesting function: The possibility to store the system 

data in the internet. Thus the remote query of each and any internet connection is possible 

and you may even present the system to your friends or to interested parties via this 

function. 

The homepage supervision (visualisation) is completely independent of your SolarLog 400e . 

Thus, you don’t need any leased line etc. and you are independent of each and any 

access portal. 

The only prerequisite is that you have got a homepage. This is an area in the internet 

which is available to you at your discretion. Normally the internet provider makes available 

the homepage free of charge. Several free-of-charge suppliers make available a 

homepage upon logon (for example: www.arcor.de ) 

An additional prerequisite is that the homepage data can be send via FTP log. 

The content of the homepage, i.e. the individual pages and graphs are available under 

www.solare-datensysteme.de/firmware. You have just to copy the files to the homepage 

without any modification. 

Then you will just have to configure the SolarLog 400e correspondingly to ensure that the 

device knows whereto regularly transfer the data. 

To summarize the prerequisites: You just need the following to set up a SolarLoghomepage: 

1. a homepage 

2. Writting via FTP log on the homepage must be possible 

3. the files for the homepage 

4. configuration at SolarLog 400e (export) 

You may of course use your own system screen. To do so, you just have to replace the file 

„solaranlage.jpg“ by your own picture. 

As soon as the homepage works correctly, the „online banner“ will be automatically 

available. This is a small graph with brief information on the system and indication of the 

daily yield. The daily yield is automatically updated depending on the set up transfer 

interval in the dialogue „export“ 

This banner maybe linked upon discretion in other homepages as an information. You will 

find the html-code in the homepage file „iframe.html: 

 

Ihr Browser kann leider keine eingebetteten Frames anzeigen: 


Sie können die eingebettete Seite über den folgenden Verweis 

aufrufen: Banner 

 

Of course you will have to modify the address after „http://“ to your own homepage. 

We would be glad to link your system to our homepage under „www.solaredatensysteme.de“ 

at „reference systems“. 

Free-of-charge Homepage 

If you do not have your own web space, Solare Datensysteme GmbH will make available a 

free of charge homepage including email messaging under www.solarlog-home.de. 

After the logon we will send you the access data (login) via email. You can enter these 

data in the SolarLog -configuration correspondingly. 

In this case all above-mentioned steps via FTP-programme etc. won’t be necessary. The 

entire homepage is already pre-configured and absolutely free of charge. 

In addition, SMS messaging in case of problems with the system is possible. In this case 

we will charge you with a minor amount of money. 


Automatic Messages 

An important item of the SolarLog 400e is the automatic messaging via email or SMS. The 

following messages are available: 

1. Failure message inverter 

2. Fault message from output monitoring 

3. Fault message from the status/error code monitoring 

4. Yield overview 

Depending on whether the message is sent via email or SMS, the text content will be 

different. This results from the text limitation to 160 characters in case of SMS messaging. 

In the following you will find some examples of the message types:

Installation Special-RS485-PiggyBack for SMA-WR 

The special PiggyBack is a simple RS485 interface converter without controller and 

without its own "intelligence". Thanks to its simple and solid structure we can rule out any 

inverter disturbance. Provided that it is correctly installed in conformity with the installation 

prescription the technical data and features of the inverter will remain unchanged. 

The special PiggyBack is to be operated exclusively in combination with the SolarLog 400e . 

The special RS485-PiggyBacks are compatible with the inverter types 

− SB-SunnyBoy 

− SMC-SunnyMiniCentral 

− SWR (as of year of manufacture: 2001). Sometimes it is necessary to remove the 

display to insert the PiggyBack. However, the problem of available space exists as well 

with the original SMA-PiggyBacks. 

Please check the accessory for completeness: 

1 piece installation insulation hose for data cable 

1 piece Jumper 

1 piece screwing/bush . WR-PG 16 (M22) 

1 piece flat blade distributor 

Important Advice for Installation 

The inverters must be opened to insert the PiggyBack interface boards. Only qualified staff 

will be authorized to do this work. In this respect please observe the instructions of the 


Installation 

Before executing work at the inverter the supply voltage must be cut. First disconnect the 

inverter from the AC line then from the DC line. Then wait 30 minutes till all the parts alive 

have become discharged. 

Please keep in mind that there are sensitive electronic components inside the inverter and 

on the interface board, these components may be damaged and destroyed by electrostatic 

discharge.

Step 1 

First place the PiggyBack onto the control board in the inverter. Take care that the 

inscription „bottom“ is readable on the board down left (see 2nd picture below). 

Advice: The lower pin strip must be mounted left aligned. 

(1) Control board without PiggyBack

Step 2 

Now the individual inverters must be wired one to the other. This is done with a 4-core 

shielded data cable (for example 25m ring, Solare Datensysteme-Article no. 220014). 

Now connect all 4 contacts (2,3,5,7) of the terminal strip of inverter 1 to inverter 2 and then 

to inverter 3 and so on till you have connected all inverters.

2,3,5,7 

In case of older SMA inverters of the type SWR there may be available the 10-pole 

terminal strip. Connect here as well the contacts 2,3,5 and 7, the other contacts will stay 

unoccupied. 

Attention: The data cable must be led through the silicone installation bushings inside the 

inverter. 


Step 3 

Now you must place a terminal resistor at the last inverter. Place the jumper to the lowest 

position: 

The center and the top position must remain bare! 

Step 4 

Place jumper 

(right at the 

bottom) 

You will now have to wire the first inverter to the SolarLog. To do so, you may either use 

the data cable attached or your own cable. 

Pass the bare conductors through the cable opening of the inverter and then connect 


White (1) 2 

Yellow(2) 3 

Green (3) 5 

Brown(4) 7 

You have now finished the hardware installation. Please close the inverter and take it 

again into operation. 

Attention! Only connect the SolarLog 400e to the main supply when all inverters feed in, 

otherwise the system won’t identify all inverters. 

Now the SolarLog 400e reads the configuration data from the inverters. This process will take 

some minutes depending on the number of inverters connected. During this period, the 

status LED 1 is off and status LED 2 flashes. Then the data recording will start 

immediately. 

(In case not all inverters have been identified, the identification process can be restarted 

via the SolarLog menue item „Inverter scan/ New identify“ – see page 59) 


Multifunction Key 

The multifunction key is especially necessary to install the SolarLog. It is not required for 

the actual operation. To prevent wrong handling it is in countersunk and can only be 

operated by means of a sharp object. 

You can select 3 modi by this key: 

1. Network search mode 

2. New identification of inverters 

3. Reset to factory settings 

The search mode for the network is especially important for the first installation of the 

SolarLog. It is explained on page 7. 

The new identification of inverters is a helpful function in case you add new inverters to an 

already existing system or in case you have to replace defective inverters. Of course it is 

possible to call up this function via a dialogue, however, during hardware installation it is 

often better to directly start the new identification without the help of the PC. 

Reset to factory settings is often the only possibility to access to the SolarLog after a 

wrong and erroneous configuration. With this function the data storage and the 

configuration storage will be initialised anew. However, this does not reset the network 

address! This is to say if the SolarLog cannot be accessed in the network it won’t be 

necessary to do the reset to factory settings but to use the network search mode to set the 

address a new. 

Procede as follows to select the individual modes: 

1. First of all switch off the SolarLog, then keep the key pressed with a sharp object. 

2. Now switch on the SolarLog. Still keep the key pressed. At the beginning status 1 

and 2 are off, then status 1 and 2 will shortly flash together. Still keep the key 

pressed till only status 1 flashes. 

3. You have now entered the installation mode. By shortly pressing the key you will 

now move to the next mode: 

Mode 1 – LED 1 flashes 

Mode 2 – LED 2 flashes 

Mode 3 – LED 1 and 2 flash 

4. Once you have selected the desired mode you press the key again for about 5 

seconds till the LEDs stop flashing. Now the respective mode has been started. 

Mode 1 – The network area is searched. Once found, the LED 1 extinguishes and 

the SolarLog will restart. 

Mode 2 – Inverter identification is started. 

Mode 3 – Reset to factory settings of the SolarLog. 

To drop out of the installation mode you will have to cut the SolarLog from the electric 

supply for several seconds. 


Useful Software 

In the internet you will find a lot of useful software which will ease your daily work with the 

computer. We have prepared a list of programmes which are especially helpful when 

working with the SolarLog. You may use the indicated programmes free of charge. 

Printing 

The SolarLog print out is activated via the internet browser print function: However, we 

recommend to use the following useful print programme which may be downloaded free of 

charge under http://www.hardcopy.de because especially the graphs are not always 

printed completely or not at all depending on the browser used. 

This programme will be linked as a small symbol top right in every Window screen and 

with a simple mouse click you can print out the current screen content (screenshot) on a 

standard printer. 

To get a print out in the landscape format adjust it as follows: 

Programme configuration: „settings / options / alignment“ option „print out landscape“, 

„on“.
