4 Solare Datensysteme SolarLog 400e
Foreword<br />
The SolarLog 400e is a newly designed device which provides the system operator with<br />
complete data recording and an extremely flexible data editing and formatting.<br />
The SolarLog 400e offers excellent functionality - for local use only and in case of a desired<br />
connection to the Internet for remote queries - with easy handling and without extra<br />
charge.<br />
One special feature is that the SolarLog 400e cooperates with various inverter providers<br />
independently <strong>fr</strong>om the manufacturer. The aim is to support as many inverters as possible<br />
in order to permit operators a uniform platform for data evaluation and analysis.<br />
Contrary to other competitor data logger products the SolarLog 400e reads out the system<br />
data directly <strong>fr</strong>om the inverter which facilitates the immediate detection of system failures.<br />
The SolarLog 400e is a slightly modified version of the previous model SolarLog 400 into which<br />
hardware and software enhancements have systematically been included with a special<br />
focus on an improved and easier installation.<br />
The SolarLog 400e has been developed starting <strong>fr</strong>om application in practice and is<br />
continuously improved. Upgrading with updates is possible at any time. Thus, in the future,<br />
you will be able to benefit of new functions.<br />
The handling via an internet browser - independent of the operating system used - is<br />
unique and future-proof. You will still be able to operate the SolarLog 400e with „Windows<br />
2015“.<br />
We wish you successful operation and many sunny and “yielding” days.<br />
SolarLog 400e Solare Datensysteme 5
Scope of supply<br />
The SolarLog 400e will be delivered with the following components:<br />
1. SolarLog 400e – central (host) device<br />
2. Connector-type power supply unit 12 Volt<br />
3. Manual<br />
4. Data cable for connection to the first inverter. An adequate data cable for the<br />
respective inverter will be supplied.<br />
The SolarLog for Fronius comprises two data cables and a terminal plug.<br />
The SolarLog for Kyocera comprises one data cable and a terminal plug.<br />
5. Drilling jig for wall mounting<br />
For the PC or network connection you will need an additional network cable (RJ45-CAT5<br />
or CAT6) of the required length.<br />
Furthermore, you will need adequate cables for wiring the inverters among each other.<br />
<strong>Installation</strong> <strong>instructions</strong><br />
Note: Please carefully read the following <strong>instructions</strong> before connecting the SolarLog 400e to<br />
the inverter or to a PC.<br />
<strong>Installation</strong> of the SolarLog 400e includes the following steps:<br />
1. Connection to the PC and/or network<br />
2. Connection to the inverter<br />
Please strictly adhere to the order of actions described in the following.<br />
6 Solare Datensysteme SolarLog 400e
Connection to the PC / Network<br />
The SolarLog 400e is equipped with a standard Ethernet-RJ45 network port which can be<br />
connected with any commercial network cable. Speeds of 10Mbit and 100Mbit are<br />
supported.<br />
In general, any PC network technology may be used to connect the SolarLog 400e . The<br />
following technologies are available:<br />
1. Direct cable connection<br />
2. Connection via a network router<br />
3. Connection via mains (Power line)<br />
4. Connection via radio network (Wlan / GSM)<br />
The <strong>instructions</strong> described in the following refer to the operating system Microsoft<br />
Windows, versions 98/ME/NT/2000/2003/XP/Vista.<br />
The network configuration has been divided into the following steps:<br />
Step 1 – Determine your own network address<br />
Step 2 – Connect SolarLog with network cable<br />
Step 3 – Configure the SolarLog network address<br />
After these 3 steps the SolarLog network configuration is completed.<br />
Step 1 – Determine your own network address<br />
If you already know the network address (IP address) of your PC, you may directly<br />
continue with step 2.<br />
Each and any appliance connected to a network has got its own network address. This<br />
address must never be used twice, i.e. allocated to a second device.<br />
In order to determine the network address of your own PC, please proceed as follows.<br />
Open command prompt (also called DOS window) on your Windows PC. Then enter:<br />
ipconfig [Enter button]<br />
The following screen appears<br />
Ethernet adapter "LAN-connection":<br />
Connection-specific DNS suffix:<br />
IP address. . . . . . . . . . . . : 10.31.1.1<br />
Subnet mask. . . . . . . . . . . : 255.255.255.0<br />
Standard gateway . . . . . . . . . : 10.31.1.254<br />
As you can see <strong>fr</strong>om the example, the IP address (network address) is „10.31.1.1“. This is<br />
your PC address.<br />
Please make a note of all 3 indications, i.e. IP address, subnet screen and standard<br />
gateway as they are required for further configuration.<br />
Important note: In the following description we will always refer to this example address.<br />
Of course you will have to replace this address by your own accordingly.<br />
SolarLog 400e Solare Datensysteme 7
Step 2 – Connect network cable<br />
Now connect the SolarLog 400e via an Ethernet-RJ45 network connector cable with the<br />
network card at your PC or, if available, with your network router.<br />
Please note that you will have to use a so-called “crossover” (twisted) network cable if you<br />
want to directly connect the SolarLog 400e to your PC.<br />
Tip: If you have available a crossover network cable, you should use it to directly connect<br />
the SolarLog 400e to your PC, if possible, for the initial configuration. This applies especially<br />
in case you intend to do the networking via power plug.<br />
As soon as the SolarLog 400e has been allocated a fix IP address, the final network<br />
configuration may be set up. This step-by-step procedure is recommended to allow quick<br />
troubleshooting.<br />
Step 3 – Configure the IP address<br />
In the next step, the SolarLog 400e will have to be configured with a network address (=IP<br />
address) .<br />
The “delivery” address is<br />
192.168.178.49<br />
This (default) setting will already match if you use the “Fritz Fon” device of AVM company<br />
as internet router. Meanwhile this device is offered quite often in connection with DSL flat<br />
rates at an advantageous price and offers an excellent price/performance ratio. In this<br />
case you will not have to configure the IP address but you can immediately go to the next<br />
chapter „Connection to the inverter“.<br />
However, in all other cases, as your PC network differs <strong>fr</strong>om this address, the IP address<br />
of the SolarLog 400 will have to be set to an unallocated address of your PC network.<br />
This is quite easily done with the SolarLog 400e as we have integrated a special mode for<br />
network detection in this device: the network search mode.<br />
Before switching on the SolarLog please hold the multi-function key (see as well page<br />
71) pressed with a sharp object. Now switch on the SolarLog and wait for about 20<br />
seconds - keeping the key pressed - until the status1-LED starts flashing. Now you can let<br />
go. By several times pressing the key you jump to the respective next mode. Thus, pay<br />
attention that only status1 flashes. (The other modes are explained on page 71). Now<br />
again press the key for about 5 seconds until the flashing stops. Now status1 is lighted.<br />
The SolarLog 400e now is in the network search mode, “listening” to any arriving data<br />
packets in order to determine the local network area. To facilitate the search, shut your PC<br />
down and reboot it again. During restart your PC sends data packets which tell the<br />
SolarLog the currently valid network area.<br />
As soon as the SolarLog is able to determine the network area, status1 will go to “off” and<br />
the SolarLog reboots - this time with a changed network address.<br />
8 Solare Datensysteme SolarLog 400e
The SolarLog has now converted independently (in our example) to the network address<br />
10.31.1.49<br />
and is now accessible with this network address.<br />
Note: The network search mode automatically determines the first three figures of a<br />
network address and then always allocates “49“ (fixed) as the fourth figure. In some rare<br />
cases this may lead to a double allocation with other network appliances which are also<br />
configured to „49“. Please make sure that the “49“ address is not allocated already in your<br />
network - at least as long as you have not switched the SolarLog manually to another<br />
address.<br />
If you don’t have available an internet router the network configuration is now complete<br />
and you can continue with section „Connection to the inverter“.<br />
Otherwise you will now have to save the network address of your internet router in the<br />
SolarLog network configuration.<br />
Start your internet browser now and enter the following in the address bar:<br />
[ip-address of SolarLog 400e ]/lan<br />
10.31.1.49/lan<br />
The configuration dialogue of the SolarLog 400e will open:<br />
At “Gateway“ now enter the network address which you have written down in step 1 of the<br />
configuration at “standard gateway.<br />
Generally, the input field “Subnet mask“ may remain unchanged, however, here as well<br />
you should enter the same sequence of numbers which you have written down in step 1.<br />
SolarLog 400e Solare Datensysteme 9
Of course you may now allocate a different network (IP) address to the SolarLog which<br />
differs <strong>fr</strong>om “49“. However, unless necessary, we recommend not to change anything.<br />
Now press the “Save” button and the network configuration is completed. All network<br />
settings will become effective only after restart of the SolarLog.<br />
Note:<br />
Unless the inverters have been detected and/or configured, the dialogues under System<br />
Supervision and Diagnosis cannot yet be used.<br />
10 Solare Datensysteme SolarLog 400e
Connection to the inverter<br />
Please take care that there is not yet any power supply to the SolarLog 400e , i.e. that it is<br />
switched off.<br />
The SolarLog 400e is designed for operation independently of the manufacturer which means<br />
that inverters of different manufacturers may be connected.<br />
Continue with the description valid for you.<br />
SMA – SunnyBoy/SunnyMiniCentral with RS485-PiggyBack<br />
Important note: Never open the casing of the inverter when it is energized/live. It is<br />
imperative to respect the advice and <strong>instructions</strong> of the SMA manual.<br />
Please stick to the following work order when installing the SolarLog 400e with the inverters:<br />
1. De-energize the inverters or wait for the evening<br />
2. Carry out all the cabling and installation work, however – do not yet connect the<br />
SolarLog 400e<br />
3. Connect the inverters to the mains supply and wait until all inverters are feeding in<br />
4. Connect the SolarLog 400e<br />
Before you can connect the SolarLog 400e to the inverter, a RS485 interface PCB, a socalled<br />
„PiggyBack“ needs to be mounted.<br />
For the use in SMA inverters two different PiggyBacks are suitable:<br />
− RS485-PiggyBack of Solare Datensysteme company (art. n°220020)<br />
− RS485-PiggyBack of SMA company (SMA art. n° 485PB-NR)<br />
Both PiggyBack types can be integrated without any restriction in all SMA inverters of the<br />
type „SunnyBoy“ or „Sunny Mini Central“, however, they have got different cabling.<br />
<strong>Installation</strong> of PiggyBack Solare Datensysteme<br />
The integration of the interface card and the cabling of the inverters is described in detail<br />
on page 66.<br />
<strong>Installation</strong> of PiggyBack-SMA<br />
The integration is described quite in detail in the SMA manual which is enclosed to the<br />
interface board. Cabling among the inverters is described on page “6 of 8“ under “Cabling<br />
of a SB / SWR via RS485 to a PC“. Connect the individual inverters, as described in the<br />
SMA manual, with a shielded 3-pole data cable.<br />
Then set the jumper A at the PiggyBack of the last inverter as described on pages “5 of 8“<br />
and “6 of 8“ in the SMA manual.<br />
You may connect the SolarLog with the first inverter either with the data cable enclosed or<br />
with your own cable.<br />
Pull the vacant conductors through the cable opening of the inverter and connect<br />

Brown(4) 7<br />
Caution! Only connect the SolarLog 400e to the power supply when all inverters are feeding<br />
in. Otherwise the system won’t detect all inverters.<br />
Now the SolarLog 400e reads the configuration data <strong>fr</strong>om the inverters. This process takes a<br />
couple of minutes depending on the number of inverters. During this period the status-<br />
LED-1 is off and status-LED-2 flashes. The recording of data will then start immediately.<br />
(In case not all inverters have been detected, the detection process can be restarted via<br />
the SolarLog menu item „Identify new inverters“– see page 55)<br />
Sunways – NT with RS485 interface<br />
Important note: Never open the casing of the inverter when it is energized/live. It is<br />
imperative to respect the advice and <strong>instructions</strong> of the Sunways manual.<br />
Pay attention that each Sunways NT inverter must be configured with a different internal<br />
address. The factory setting is always address 1. The Sunways manual describes how to<br />
configure the addresses which can be done via the operating display of the inverter. It is<br />
recommended to determine the addresses successively starting <strong>fr</strong>om 1, i. e. 1, 2, 3 and so<br />
on.<br />
Please stick to the following work order when installing the SolarLog 400e with the inverters:<br />
1. De-energize the inverters or wait for the evening<br />
2. Carry out all the cabling and installation work, however – do not yet connect the<br />
SolarLog 400e with the green terminal-strip plug<br />
3. Connect the inverters to the mains supply and wait until all inverters are feeding in<br />
4. Connect the SolarLog 400e<br />

Now connect the individual inverters with each other via the RS485 terminal strips using<br />
shielded 2-pole data cables as described in the Sunways manual. The RS485 each are<br />
executed as double connectors which allow to continue the cabling.<br />
You may connect the SolarLog with the first inverter either with the data cable enclosed or<br />
with your own cable.<br />

The jumper JP400e must be placed at the inverter farest <strong>fr</strong>om the SolarLog, all other<br />
inverters must not be placed with this jumper.<br />
Note: Only plug in the green terminal-strip plug to the SolarLog 400e once all inverters are in<br />
operation. Otherwise the system won’t detect all inverters.<br />
Now the SolarLog 400e identifies all inverters in turn. This process will take some minutes.<br />
During this period, the status LED 1 is off and status LED 2 flashes. Then the data<br />
recording will start immediately.<br />
(In case not all inverters have been detected, the detection process can be restarted via<br />
the SolarLog menu item „Identify new inverters“– see page 55)<br />
Kaco – Powador / PVI-BluePlanet with RS485 interface<br />
Important note: Never open the casing of the inverter when it is energized/live. It is<br />
imperative to respect the advice and <strong>instructions</strong> of the Kaco manual.<br />
Powador<br />
All Powador models are delivered ex works with an integrated RS485 interface. However,<br />
the interface will have to be activated via the operating display. In addition, you will have to<br />
allocate a unique communication address to each inverter. It is recommended to<br />
determine the addresses successively starting with 1, i.e. 1, 2, 3 and so on. This setting as<br />
well is done via the operating display. Please follow the <strong>instructions</strong> given in the Kaco<br />
manual.<br />
SolarLog 400e Solare Datensysteme 13
PVI-BluePlanet<br />
The PVI-BluePlanet models were delivered until approx. mid of 2005 and either equipped<br />
ex works with an optional RS232 or RS485. For the operation with the SolarLog 400e the<br />
RS485 option is compulsory. Retrofitting of the interface is possible via Kaco company.<br />
Please ask your installer or directly contact Kaco.<br />
You will have to allocate a unique communication address to each inverter. The allocation<br />
is done via a DIP switch inside the inverter. Please follow the <strong>instructions</strong> given in the<br />
Kaco manual. It is recommended to determine the addresses successively starting with 0,<br />
i.e. 0, 1, 2 and so on.<br />
Note: If there is no DIP switch on the control PCB then this PVI-BluePlanet inverter is<br />
equipped with the RS232 version.<br />
Cabling/wiring<br />
The individual inverters are cabled via terminal strips inside the device.<br />
Please stick to the following work order when installing the SolarLog 400e with the inverters:<br />
1. De-energize the inverters or wait for the evening (However, the input via the<br />
display must be executed during the day in case of the Powador models.)<br />
2. Carry out all the cabling and installation work, however – do not yet connect the<br />
SolarLog 400e with the green terminal-strip plug<br />
3. Connect the inverters to the mains supply and wait until all inverters are feeding in<br />
4. Connect the SolarLog 400e<br />
Terminal strip – Powador models:<br />

14 Solare Datensysteme SolarLog 400e
Now connect the individual inverters with each other via the RS485 terminal strips using<br />
shielded 2-pole data cables as described in the Kaco manual. The RS485 each are<br />
executed as double connections which allow to continue with the cabling. To do so,<br />
connect the terminal A to the terminal A of the next inverter respectively and proceed<br />
correspondingly with terminals B.<br />
You may connect the SolarLog with the first inverter either with the data cable enclosed or<br />
with your own cable.<br />
Pull the vacant conductors through the cable opening of the inverter and connect<br />
SolarLog to terminal strip in the inverter<br />
White (1) B<br />
Brown(4) A<br />
In addition, a terminal resistor of 330Ohm (attached to inverter) must be placed at the<br />
terminal strip of the inverter farest <strong>fr</strong>om the SolarLog. The terminal resistor connects the<br />
<strong>fr</strong>ee terminal A with terminal B.<br />
Note: If the cable lengths are quite short, you may possibly do without terminal resistor.<br />
Note: Only plug in the green terminal-strip plug to the SolarLog 400e once all inverters are in<br />
operation. Otherwise the system won’t detect all inverters.<br />
Now the SolarLog 400e identifies all inverters in turn. This process will take some minutes.<br />
During this period, the status LED 1 is off and status LED 2 flashes. Then the data<br />
recording will start immediately.<br />
(In case not all inverters have been detected, the detection process can be restarted via<br />
the SolarLog menu item „Identify new inverters“– see page 559)<br />
SolarMax – Serie C and E with RS485 interface<br />
Important note: Never open the casing of the inverter when it is energized/live. It is<br />
imperative to respect the advice and <strong>instructions</strong> of the SolarMax manual.<br />
C-Series<br />
With all C-series models the RS485 interface is already integrated ex works. You will have<br />
to allocate a unique communication address to each inverter. It is recommended to<br />
allocate the addresses successively starting with 1, i.e. 1, 2, 3 and so on. This setting is<br />
also done via the operating display. Please follow the <strong>instructions</strong> given in the SolarMax<br />
manual.<br />
E-series<br />
The E-series models are not equipped with a communication interface in their standard<br />
version. Thus they need to be retrofitted with an appropriate interface prior to connecting<br />
them to the SolarLog.<br />
Please follow the installation <strong>instructions</strong> attached to that interface. Especially consider the<br />
correct setting of the RS485/RS232 jumper and of the terminal resistor on the interface<br />
card (see manual for interface card).<br />

on. This setting as well is done at the operating display. Please follow the <strong>instructions</strong><br />
given in the SolarMax manual.<br />
Cabling<br />
The individual inverters are cabled with each other using conventional network cables<br />
equipped with an RJ45 plug.<br />
Please stick to the following work order when installing the SolarLog 400e with the inverters:<br />
SolarMax C series:<br />
1. Cabling may be done at any time because it is not necessary to open the inverters.<br />
2. Carry out the entire cabling and installation – however, do not yet connect the<br />
SolarLog 400e to the green terminal strip plugs of the enclosed data cable<br />
3. Connect the SolarLog 400e as soon as all inverters are feeding in<br />
SolarMax E series:<br />
1. De-energize the inverters or wait for the evening (However, the input via the<br />
display required to set the communication address must be executed during the day.)<br />
2. Carry out all the cabling and installation work, however – do not yet connect the<br />
SolarLog 400e with the green terminal-strip plug<br />
5. Connect the inverters to the mains supply and wait until all inverters are feeding in<br />
6. Connect the SolarLog 400e<br />
Connect all SolarMax inverters with each other via conventional network cables.<br />
SolarMax C series:<br />
On the bottom of the device you will find the two RJ45 jacks for system communication.<br />
Plug in one of the cable plugs in any jack of the first inverter. Take the other plug of the<br />
cable and plug it in any connector of the second inverter. In the same way connect the<br />
inverter n° 2 with inverter n° 3 etc.<br />
The RJ45 plug of the enclosed data cable of the SolarLog is then plugged to the vacant<br />
connector of the last inverter.<br />
SolarMax E series:<br />
As the RJ45 connector jacks are inside the inverter at the interface card, the network<br />
cables must be fed through the cable bushing at the bottom of the device. Except for the<br />
first inverter, always two cables are passed through the bushing: One cable <strong>fr</strong>om the<br />
previous inverter and one cable to the next inverter or to the SolarLog. Plug the cable of<br />
the previous inverter to the left jack with the inscription „RS-485 in“ and the cable to the<br />
next inverter to the right jack with the inscription „RS-485 out“.<br />
Now plug the data cable with the RJ45 plug (enclosed to the SolarLog) into the last<br />
inverter..<br />
Note: Only insert the green terminal block plug to the SolarLog 400e if all inverters are<br />
operating. Otherwise the system won’t detect all inverters<br />
16 Solare Datensysteme SolarLog 400e
Now the SolarLog 400e identifies all inverters in turn. This process will take some minutes.<br />
During this period, the status LED 1 is off and status LED 2 flashes. Then the data<br />
recording will start immediately.<br />
(In case not all inverters have been detected, the detection process can be restarted via<br />
the SolarLog menu item „Identify new inverters“– see page 559)<br />
Fronius – IG15-60 with ComCard<br />
Important note: Never open the casing of the inverter when it is energized/live. It is<br />
imperative to respect the advice and <strong>instructions</strong> of the Fronius manual.<br />
Please stick to the following work order when installing the SolarLog 400e with the inverters:<br />
5. De-energize the inverters or wait for the evening<br />
6. Carry out all the cabling and installation work, however – do not yet connect the<br />
SolarLog 400e<br />
7. Connect the inverters to the mains supply and wait until all inverters are feeding in<br />
8. Connect the SolarLog 400e<br />
Before connecting the SolarLog 400e to the inverter, an interface PCB - a so called<br />
„ComCard“ - needs to be installed.<br />
<strong>Installation</strong> Fronius-ComCard<br />
The ComCard may optionally already be installed ex works or may be retrofitted as<br />
„ComCard retrofit“.<br />
Note: The inverter must be opened for the installation work. Please absolutely follow the<br />
prescriptions given in the Fronius-IG manual of your inverter!<br />
The installation of the ComCard is described in great detail in the inverter manual, please<br />
follow all <strong>instructions</strong>.<br />
We recommend leaving vacant one connector place between the installed ENS card and<br />
the ComCard.<br />
Communication address<br />
You will have to allocate a unique communication address to each inverter. We<br />
recommend allocating the addresses successively starting with 1, i.e. 1, 2, 3 and so on.<br />
This setting is carried out at the operating display.. Please follow the <strong>instructions</strong> given in<br />
the Fronius manual, chapter “Operating concept“, section “Setup menu“.<br />
Cabling<br />
The individual inverters are cabled with each other with conventional network cables<br />
equipped with an RJ45 plug..<br />
Each ComCard has got two RJ45 jacks marked with “IN“ and “OUT“ respectively. It is key<br />
to observe the correct cabling order as otherwise there will not be any data exchange.<br />
Caution! The SolarLog is as well equipped with a RJ45 jack. By no means this jack must<br />
be connected to the RJ45 socket of the inverters. This could destroy the SolarLog!<br />

RS485 interface<br />
For data monitoring with the SolarLog an RS485 interface is required. As of 02/2007 this<br />
interface has already been factory-mounted in all inverters. Previously delivered models<br />
were either equipped with RS485 or with a wireless interface. However, you cannot use<br />
the wireless interface for the SolarLog. In this case the RS485 interface needs to be<br />
retrofitted by your qualified solar installer.<br />
No further settings at the inverter display are required.<br />
Cabling<br />
The individual inverters are cabled with each other with conventional network cables<br />
equipped with an RJ45 connector. The two RJ45 jacks are at the right side in the lateral<br />
cover panel which can be screwed off. Please consider the <strong>instructions</strong> given in the<br />
Kyocera manual.<br />
On the bottom of the device you will find the two RJ45 jacks for system communication.<br />
Plug in one of the cable plugs in any jack of the first inverter. Take the other plug of the<br />
cable and plug it in any connector of the second inverter. In the same way connect the<br />
inverter n° 2 with inverter n° 3 etc.<br />
Insert the RJ45 connector of the data cable enclosed to the SolarLog to the still vacant<br />
jack of the first inverter. Insert the enclosed terminal connector into the vacant jack of the<br />
last inverter.<br />
Note: Only insert the green terminal block plug to the SolarLog 400e if all inverters are<br />
operating. Otherwise the system won’t detect all inverters<br />
Now the SolarLog 400e identifies all inverters in turn. This process will take some minutes.<br />

Power-One/Aurora with RS485 interface<br />
Important note: Never open the casing of the inverter when it is energized/live. It is<br />
imperative to respect the advice and <strong>instructions</strong> of the Power-One manual.<br />
All Power-One inverters are equipped with an RS485 interface ex works. In addition, a<br />
unique communication address must be allocated to each inverter. We recommend to<br />
allocate the addresses successively starting with 2 (not 1!), i.e. 2, 3, 4 etc. This setting as<br />
well is done at the operation display. Please follow the <strong>instructions</strong> given in the Power-<br />
One/Aurora manual.<br />
SolarLog 400e Solare Datensysteme 19
Cabling<br />
Cabling of the individual inverters is done via terminal strips inside the device. In case of<br />
the indoor/outdoor models, there are sometimes integrated different interfaces. In the<br />
following we will go into details about the cabling with RS485.<br />
Please stick to the following work order when installing the SolarLog 400e with the inverters:<br />
1. De-energize the inverters or wait for the evening (However, the input via the<br />
display must be executed during the day.)<br />
2. Carry out all the cabling and installation work, however – do not yet connect the<br />
SolarLog 400e with the green terminal-strip plug<br />
Connect the inverters to the mains supply and wait until all inverters are feeding in<br />
Connect the SolarLog 400e<br />
Terminal strip – Outdoor models:<br />
As described in the inverter manual, connect the individual inverters with each other via<br />
the RS485 terminal strips using a screened 3-pole data cable. Connect terminal “+T/R“<br />
with terminal “+T/R“ of the following inverter respectively and the terminals “-T/R“ and<br />
“RTN“ correspondingly.<br />
For the connection of the SolarLog with the first inverter you may either use the data cable<br />
enclosed or your own cable.<br />
Pull the vacant conductors through the cable opening of the inverter and connect<br />

In addition, the terminal resistor must be placed at the inverter farest <strong>fr</strong>om the SolarLog. To<br />
do so, the small switch must be turned to position “ON“.<br />
Note: Only insert the green terminal block plug to the SolarLog 400e if all inverters are<br />
operating. Otherwise the system won’t detect all inverters<br />

Mitsubishi with RS485 interface<br />
Important note: Never open the casing of the inverter when it is energized/live. It is<br />
imperative to respect the advice and <strong>instructions</strong> of the Mitsubishi manual.<br />
All Mitsubishi inverters are factory-equipped with the RS485 interface. In addition, a unique<br />
communication address must be allocated to each inverter. We recommend to allocate the<br />
addresses successively starting with 1, i.e. 1, 2, 3 and so on. This setting is carried out at<br />
the operating display. Please follow the <strong>instructions</strong> given in the Mitsubishi manual.<br />
(Address number 1 is preset at all Mitsubishi inverters).<br />
Cabling<br />
Cabling of the individual inverters is done using conventional phone cables equipped with<br />
an RJ11 connector which is always of the 6-pole type. Normally however, only the 4 centre<br />
pins are used which is totally sufficient. The important thing is that the 4 (or 6) pins are<br />
looped through 1 to 1.<br />
The two RJ11 jacks are on the bottom left inside the inverter. For installation it is<br />
necessary to screw off the <strong>fr</strong>ont panel of the inverter. Please observe the <strong>instructions</strong> given<br />
in the Mitsubishi manual.<br />
Now connect all inverters with each other using the RJ11 cables.<br />
Insert the cable connector in any one jack of the first inverter. Insert the other connector of<br />
the cable into any one jack of the second inverter. Proceed in the same way to connect the<br />
inverter n° 2 with inverter n° 3 etc.<br />
Insert the data cable with the RJ11 connector enclosed to the SolarLog to the still vacant<br />
jack of the first inverter.<br />
Note: Only insert the green terminal block plug to the SolarLog 400e if all inverters are<br />
operating. Otherwise the system won’t detect all inverters<br />
Now the SolarLog 400e identifies all inverters in turn. This process will take some minutes.<br />

There are various options to visualise the yield data. The data may be displayed in a fullscreen<br />
view or alternatively in a small view especially developed for PDAs. Furthermore,<br />
all data may be transferred to an Internet homepage allowing remote enquiries.<br />
In each view you will have the choice between daily, monthly and annual overview, partly<br />
this choice is available in a general overview on all years which have been saved.<br />
There is always the option to select previous periods (e. g. day before or previous month)<br />
via the respective arrow symbols “Forward“/“Back“.<br />

This standard view will open in a separate window and contains<br />
− daily overview<br />

Daily overview<br />
The programme always starts with the current date of the day in daily view. With the arrow<br />
symbols top left you may select various days in retrospective.<br />
The daily yield curve is composed of averaged 5 minute values.<br />
24 Solare Datensysteme SolarLog 400e
Depending on the number of connected inverters (max. 20) the respective number of<br />
inverter symbols will appear. The symbol at the very left stands for all inverters, the<br />
symbols right of it stand for an individual inverter respectively. The symbol’s colours solely<br />
serve to distinguish the single inverters. Each symbol may be selected separately and it is<br />
possible to combine several or all with each other. A symbol with a „tick“ means that the<br />
yield information of the desired inverter is displayed. If only one single inverter is ticked,<br />
this inverter is shown with all available string information. Of course this will only work if<br />
this inverter is a multi-string model.<br />
The yield curve of all inverters as a whole or of only one single inverter is shown as a<br />
yellow area. Secondary information, i.e. information about individual inverters or on single<br />
strings, is shown in coloured lines.<br />
The Y-scale results automatically <strong>fr</strong>om the inverters selected and is determined based on<br />
the maximum performance <strong>fr</strong>om the inverter configuration.<br />
Via the control buttons on the right you may have shown additional information, if needed.<br />
Yield: Here, the yield line is shown. It indicates the current accumulated daily total. In<br />
addition, a green line exhibits the targeted daily total.<br />
Udc: Shows the generator voltage. In order to display the voltage of the individual<br />
strings only 1 inverter must be selected.<br />
kWp: This allows to switch the scale on the left <strong>fr</strong>om “output in Watt“ to “output in<br />
kW/kWp“, i.e. the output value of a string and/or inverter is divided by the<br />
connected generator output. Thus, all curves become comparable as to their<br />
specific output and the output/performance can be visually checked. Strings with<br />
the same module orientation and the same slope must “overlap”, i.e. be lying upon<br />
each other. If not, we most often find there a shading, however, it may as well<br />
indicate an installation fault, e.g. the connection of a module has been “forgotten”<br />
or has been connected to a wrong string. Decreasing module outputs may be<br />
detected, too.<br />
°C: Here, the internal inverter temperature is displayed. Especially with devices<br />
equipped with a fan it is possible to indirectly determine whether the fan still works<br />
correctly and discharges the hot air to the outside. Please take into account that<br />
inverters are designed for high internal temperatures. The temperature is only<br />
displayed with inverters delivering the respective measuring value (e. g. not with<br />
SMA and Fronius).<br />
The table below the graph always displays the current values on the left side. On the right<br />

Diagnosis<br />
The main task of the SolarLog 400e is the early detection of system problems. Apart <strong>fr</strong>om the<br />
automatic alarm messages via e-mail and SMS, the SolarLog 400e offers the additional<br />
diagnosis features under this menue item. This features are available at any time.<br />
Event Log<br />
The SolarLog 400e individually monitors and analyses each and any inverter connected. This<br />
implies as well the permanent readout of the internal status and error codes. These codes<br />
may differ <strong>fr</strong>om one inverter to the other; they are explained in the inverter manuals.<br />
Note SMA-codes: The designations shown in the SolarLog are always original SMA-<br />
designations. The major part of them is explained in the SMA inverter manual.<br />
Each change in status and error codes will be exactly logged in the event log. It records as<br />
well the off-line periods, i.e. the periods during which the inverter is switched off.<br />
We recommend to regularly check the event log for irregularities.<br />
Possible irregularities :<br />
− power mains disconnection during the day<br />
− <strong>fr</strong>equent derating of an inverter. In this case, the inverter steps down (derates) the fedin<br />
power due to overload or excessive operating temperatures.<br />
However, it is absolutely normal to find the status repetitively changing in the morning or in<br />
the evening, i.e. when the inverter leaves its „night phase” or again enters into the switchoff<br />
phase.<br />
The event log is prepared in form of a table which always shows all current records. The<br />
log offers a capacity of 400 events.<br />
34 Solare Datensysteme SolarLog 400e
Degradation<br />
In the course of the years, the solar modules „age“, i.e. their yield gradually decreases<br />
even with the same solar radiation available.<br />
The module manufacturers grant output warranties normally they guarantee rated outputs<br />
of 80% for 20 to 25 years. However, how to compare and evaluate the module output over<br />
the course of the years? As a matter of fact, every year offers different climatic conditions<br />
and is hardly comparable to another.<br />
Here the SolarLog 400e offers a statistical evaluation of each individual year based on the<br />
daily records.<br />
It calculates the average daily maximum value for each year.<br />
This average value is calculated <strong>fr</strong>om the actual maximum values corrected by a statistical<br />
approximation to filter extreme peaks.<br />
The comparison of the calculated maximum values provides an indication on the system<br />
performance. Of course data comparison requires a sufficient number of data records per<br />
year as well as identical system technology and components. The days in spring and<br />
summer are especially important for the comparison because here we will get the<br />
maximum yields.<br />

Configuration<br />
The configuration serves to optimally match the SolarLog 400e to your demands and<br />
requirements.<br />
The SolarLog 400e has got two operating modes:<br />
1. Online mode – The inverter delivers data (day operation)<br />
2. Offline mode – The inverter does not deliver any data (night operation)<br />
During online operation, i. e. during the day, the configuration dialogues are blocked.<br />
Configuration is only possible in the offline mode which may be manually activated in the<br />
main menu, if need be. In this case the SolarLog will be in the offline mode for about 5<br />
minutes and then it will automatically switch back to online mode.<br />
If you call a configuration dialogue, this offline period will be prolonged by another 5<br />
minutes.<br />
Basic Configuration<br />
The basic configuration comprises the major settings. These settings normally do to<br />
operate the device without an Internet connection.<br />
LAN - Settings<br />
SolarLog 400e Solare Datensysteme 37
We have already dealt with the network settings in the chapter „<strong>Installation</strong> Instructions“,<br />
the settings executed according to these <strong>instructions</strong> do not require any change under<br />
normal conditions.<br />
However, a modification will always be necessary if the network addresses are changed to<br />
other areas. Please remember to convert the SolarLog 400e in due time to the new network<br />
address.<br />
Internet access<br />
Please adjust here how the SolarLog 400e is connected to the Internet.<br />
Inverter<br />
In this dialogue you can save all data relevant to the inverters. With SMA/Kyocera devices,<br />
the appliance designation and the serial number are automatically read out. For the<br />
inverters of other manufacturers the communication address will be shown.<br />
Please check that all inverters have been correctly recognized. Every inverter is uniquely<br />
identified by its serial number.<br />
The inverters are always indicated sorted according to the serial number or the<br />
communication address. With a classification according to the serial number (SMA) the<br />
inverter position may be changed to another number by using the field “new number”. This<br />
38 Solare Datensysteme SolarLog 400e
allows to easily set the desired inverter order. However, the order will have to be fixed<br />
immediately after the inverter recognition.<br />
Installed Generator Power<br />
This is the module output in Wp connected to the inverter. The overall output (power) is<br />
calculated based on the module output x number of modules (in total at the single inverter,<br />
not the overall system).<br />
Pac Correction factor<br />
When comparing the power yield indicated by the inverter with the values indicated by a<br />
calibrated current meter, we will find a deviation. Either the inverter indication is too high or<br />
too low. In order to at least roughly compensate for this inaccuracy, it is possible to define<br />
here a correction factor.<br />
SolarLog 400e Solare Datensysteme 39
Internally all yield data are always saved without any correction factor. This factor is only<br />
applied at the moment of data output. Thus it is always possible to adjust this factor at a<br />
later date.<br />
The formula to calculate the correction factor is:<br />
yield current meter / yield inverter * 1000<br />
If the inverter is not equipped with a display, a correction factor of 1000 will have to be kept<br />
first at to be able to determine a factor after about one week.<br />
Initial nominal output<br />
Please indicate here the nominal inverter output. You will find these data in the operating<br />
manual of your inverter. It is used for later diagnosis calculations and is not important now.<br />
Identification<br />
Short description of the inverter, in case of Non-Multi-String-Inverters may be the position<br />
of the connected modules.<br />
Supervision<br />
An important function of the SolarLog 400e is the monitoring of the single inverters, their<br />
strings and the connected modules. Malfunctions may be indicated via e-mail and SMS.<br />
The following will be monitored and detected:<br />
− inverter failure<br />
− power or output decrease of a module field<br />
The monitoring is based on the permanent output comparison of all inverters including the<br />
individual strings in case of Multi-String-Inverters. In case the target output deviates <strong>fr</strong>om<br />
the actual output (taking into account a defined tolerance) then the system may trigger a<br />
fault message after a selectable delay.<br />
Every connected string is assigned to a module field. The module fields are divided<br />
according to same solar module type, module inclination and orientation. If, within one<br />
system, all modules are of the same type with the same orientation, then only a single<br />
module field will be defined, for example “1”. Non-assigned (vacant) strings must be<br />
switched off with “0”. In case of different orientations additional module fields must be<br />
defined.<br />
In the ideal case, each field is made up of at least two individual strings monitoring each<br />
other.<br />
Example:<br />
A system with 23.6 kWp is divided into 3xSMA SB5000TL, 2xSMA SB2500, thereof 18<br />
kWp with 30° inclination on the roof of a barn, 20° SE-deviation and on an adjacent garage<br />
5 kWp floor-mounted 32° inclination, 0° south deviation.<br />

Garage 1.SB2500 2500 2<br />
Garage 2.SB2500 2500 2<br />
All connected strings can be monitored by each other, the strings belonging to module field<br />
1 through several strings, and for module field 2 both strings reciprocally.<br />
If the output of the single module decreases, the string output will decrease as well with<br />
still the same radiation, this decrease will be detected and reported.<br />
This output or power comparison is always reliable – even in case of clouds. However, it is<br />
important that there is no shadowing on the modules. Therefore, in configuration, it is<br />
possible to define a monitoring period during which any shadowing can be reliably ruled<br />
out. Considering that the power measuring inside the inverter becomes rather inexact<br />
below a defined threshold value, you may as well fix a minimum percentage below which<br />
monitoring will be suspended.<br />
Unfortunately there may as well be fault reports or messages when the modules are<br />
covered by snow. These messages or report result <strong>fr</strong>om the output comparison and occur<br />
in case of partial coverage or failure messages due to the complete snow cover which<br />
causes the inverter not to switch on at all.<br />
There are two possible procedures to minimize this problem:<br />
1. The minimum percentage at which output monitoring will start should be as high as<br />
possible, for example 30 %. With a generator power of 4500 Wp the monitoring will<br />
start only at 1350 W. However, the power of the unshadowed modules is reduced<br />
by partially shaded modules such that we rarely or never achieve the required 1350<br />
W. In this case the problem of partial covering has been solved.<br />
2. The system will always produce failure messages, if the inverter does not work / is<br />
not online, during the period of time set as unshadowed. The system assumes that<br />
there is a defect. Thus, a complete snow cover would be indicated as well as a<br />
failure. To solve this problem, the system contains an indicator for snow covering. If<br />
this indicator has been activated, there won’t be any failure message if all inverters<br />
are off line. It may happen that all installed inverters are defective ( for example in<br />
case of a lightning stroke ). However, this is rather unlikely. If the indicator is<br />
activated, the system will assume that the inverters do not work because the<br />
modules are completely covered by snow. In addition, this indicator depends on the<br />
actual date: it will be taken into account only <strong>fr</strong>om the beginning of November till the<br />
SolarLog 400e Solare Datensysteme 41
end of April. Apart <strong>fr</strong>om this period, i.e. in spring, summer and autumn, the indicator<br />
is automatically deactivated. The monitoring will work then as usual and will report<br />
as well the complete failure of all inverters.<br />
The duration of the error or failure indicates how long a failure or error must permanently<br />
exist to be recognized as “error” by the system. The minimum error duration is 5 minutes.<br />
However, a longer period should be selected.<br />
To avoid an excessive reporting of the occuring failures or errors it is possible to define a<br />
maximum number of messages per day.<br />
Graph Scaling<br />
In the normal case it is not necessary to change these settings because the SolarLog<br />
automatically calculates the values when the generator power is entered. However, you<br />
can adapt these values to your own requirements.<br />
For each period (value of the day, the month, the year, total) you can enter the maximum<br />
value to be reached in kW (except for day).<br />
Forecast<br />
The forecast serves to get an idea whether the system will reach the desired annual yield<br />
or not already in the course of the current year.<br />
For this purpose each month will be allocated a percentage by share calculated based on<br />
the German yield statistic of the past few years.<br />
42 Solare Datensysteme SolarLog 400e
Of course we never know exactly how the summer will be and whether a month will be<br />
completely „corrupted“. However, the annual forecast is normally rather precise and<br />
reliable already in September.<br />
The SolarLog 400e calculates the target value always accumulated to the exact day. Thus, it<br />
will not request the entire monthly target yield already at the beginning of the month but<br />
only the already past days of the month including the current day. In the forecast the<br />
SolarLog includes as well the yields reached in the previous years and thus is able to allow<br />
for local weather (for example: biggest amount of snow in December).<br />

Enter here the desired annual target value in kWh/kWp.<br />
Monthly Shares<br />
The monthly shares must reach a total of 100 %. If not, you can adapt the values to the<br />
local conditions. However, it is normally not necessary to change here anything.<br />
Graph<br />
SolarLog 400e Solare Datensysteme 43
The graph view is determined by the scaling of the X- and Y-axis.<br />
On the X- axis you will find the course in time, on the Y- axis you will find the measured<br />
value.<br />
For the day view it is necessary to define the start and the end of the day for every month<br />
in order to prevent that the data start or end will be lost in the graph.<br />
Advice: The SolarLog 400e operates independently of this configuration and it gathers the<br />
data as soon as the inverter provides them and it stops as soon as the inverter switches to<br />
night shut-down.<br />
Thus, the two top input lines are always assigned to start of the day and the two data lines<br />
at the bottom are always assigned to end of the day.<br />
Normally no modification is required here.<br />
Expert Mode<br />
Under „configuration expert“ you will find in particular those functions related to the<br />

The following email providers, among others, offer this service: „T-Online“, „Arcor“ and<br />
„GMX“.<br />
„Earning in subject heading“ (earning = yield) indicates that the SMS text is in addition<br />
written into the subject heading. In case of emails received some email providers send out<br />

Export serves to regularly transfer the yield data to a homepage and thus to be able to<br />
present the system including the online data in the internet.<br />
Modify the examples given and enteri your own data.<br />
Under „FTP server“ you will normally enter the name of the homepage.<br />
„Login“ and „Password“ are the login data to the homepage.<br />
It will only be necessary to make an entry under „directory“ if the SolarLog homepage is<br />
not assumed to be directly shown in the main directory on your homepage. Otherwise, this<br />
field may stay blank.<br />
The update interval determines how often the SolarLog 400e transfers the data. It will always<br />
copy all the 5-minutes-data not yet sent out even if the interval is by far longer, for example<br />
an hour. Depending on the internet tariff you can choose here indirectly the desired<br />
transmission volume. To give you a reference, it is assumed that a maximum of about 10<br />
Kbyte will be transferred with each transmission, this is not very much.<br />
If you want to “feed” the SolarLog homepage via this export, please select the „SolarLog“<br />
data format. As an alternative or as well in addition you can choose the data export in the<br />
CSV format. In this case the files will be exported to the homepage in a format which is<br />
Excel readable. There you can use the data for additional evaluations, if need be. The<br />
export is done in the morning and in the evening (at the switching between online/offline)<br />
for all the saved data. In addition the 5-minutes-data are always saved with the date of the<br />
day, thus there will be set-up an archive containing already very old data which have been<br />
overwritten in the SolarLog 400e (-> circular buffer).<br />
Advice: The data transmission will not be realised immediately after the configuration, it<br />
may take about up to 12 hours to transfer all the data. The reason is that older data with a<br />
higher volume are only transferred when the inverter switches on and off (online/offline).<br />
To speed up this prodedure, just shortly switch on and off the SolarLog. After about 10<br />
minutes the data transmission will be executed.<br />
In case of problems with data transmission, you can check in the fields „last transmission“<br />
and „status“ when the SolarLog 400e last tried to copy data.<br />
Possible status codes:<br />
1 – FTP-Server not found. Please check correct spelling<br />
2 – FTP-Server connected but no availability message received<br />
3 – Wrong user name<br />
4 – Wrong password or password not accepted<br />
5 – Unable to switch to the desired directory<br />
6 – Impossible to send file<br />
7 – Error at logout<br />
8 – IP address cannot be identified<br />
You can test the data sent out directly during configuration with the button „start test<br />
transmission“. Before doing so, please save the modified settings.<br />
Those who do not have an internet access via router, i.e. the SolarLog 400e is not equipped<br />
with an internet access, may as well export the data manually (in the CSV format) to the<br />
hard disk.<br />

Backup - automatic<br />
Here a regular data backup on any homepage may be configured per FTP log. The<br />
backup includes all statistical data. As each transmission includes larger data volumes (>1<br />
Mbyte) the automatic backup must not be activated in case of analogous and mobile radio<br />
transmissions.<br />
Backup - manual<br />
If there is no access to the internet the backup may as well be realised manually. In this<br />
case a file will be saved directly in an optional directory on the PC.<br />
It is as well possible to reimport an old backup. This may becöme necessary for example<br />
in case of a software update.<br />
Correction of data<br />
Under this item it is possible to always correct the day total or enter it anew at a later date<br />
for each and any day.<br />
You will always have to enter the date as an 8-digit entry, i.e. two digits for the day, two for<br />
the month and two for the year – separated by a decimal point.<br />
The day value is entered in Wh, it must correspond to the current meter reading, i.e.<br />
correspond to the actual day value.<br />
Data import of old daily data<br />
It is as well possible to import the initial inventory of manually recorded daily data into the<br />
SolarLog 400e . This will always make sense if you intend to collect a large amount of data<br />
retroactively which will take too long with the function “correction of data”.<br />
The file must be composed of individual text lines in which a date of the day and the daily<br />
yield value „Wh“ must be separated by semicolon.<br />
Example:<br />
01.04.06;136435<br />
02.04.06;128219<br />
etc.<br />
Advice: Here, the year may be indicated as a 4-digit date.<br />
In case of a data import the available data storage is completely deleted before the daily<br />
data are imported. Therefore the data import should be realised immediately after the<br />
SolarLog start-up.<br />
The overall value of the day is divided on prorata basis according to the configured inverter<br />
output. Please keep in mind that the total of the configured inverter output corresponds to<br />
the value of the system overall output in configuration/basis dialogue. If not, the SolarLog<br />
will display deviating daily values after the data import.<br />
Please enter the current meter reading. The daily value will be corrected accordingly via<br />
the correction factor. In case the correction factor is not known at the beginning the value<br />
should be set to 1000.<br />
SolarLog 400e Solare Datensysteme 53
Data import will only be possible if all inverters have been correctly recognized and set up.<br />
Advice: Please check whether the data format meets the aforesaid requirements. To do<br />
so, start the programme „wordpad“ available under each and every Windows installation.<br />
Then you open the legacy data file to check the data format. At the beginning and at the<br />
end of the line there must not be any apostrophe. You may as well immediately correct the<br />
data file with Wordpad and then save it.<br />
System<br />
54 Solare Datensysteme SolarLog 400e
The „system data“ are all data stored by you in the configuration. Therefore we<br />
recommend a backup of system data each time you change the configuration.<br />
After a firmware update it is possible that all data have been initialised anew, i.e. they have<br />
been deleted. In this case your first task will be to import the system backup after the<br />
firmware update.<br />
If the inverter configuration at the system has been modified, for example a defective<br />
inverter has been replaced, you will have to inform the SolarLog and “introduce” it to this<br />
new device. To do so, use the function „Inverter scan/ New identify“. (You can call this<br />
function as well with the multi function key, see page 67.)<br />
In case of the SMA inverter, this function must always be used in case of replaced or new<br />
inverters!<br />
With inverters of other manufacturers the following applies: In case of a replacement, the<br />
communication address of the replacing device should always correspond to the address<br />
of the old device, then the new identification won’t be necessary. In case of an additional<br />
inverter the new identification will have to be started here as well.<br />
Via the item „reset to factory settings“ you can reset the SolarLog to its delivery state.<br />
(This function may as well be activated with the multi-function key, see page 71.)<br />
However, the network settings will not be reset, this is to say the IP address will remain<br />
unchanged.<br />
All configuration data, all the data already gathered and the inverter configuration will be<br />
deleted. As a result the SolarLog will try again to identify the inverters. This will be<br />
necessary if<br />
1. Not all inverters have been recognized at the initial installation<br />
2. If there have been subsequent changes in the inverter configuration. The system<br />
especially does not automatically identify additional inverters. This identification will<br />
only be done after the reset to factory settings.<br />
Attention! The SMA inverters are internally provided with their own independent<br />
configuration and own address. Thus every replaced inverter will have to be<br />
identified anew via an inverter identification and then adopted in the system. On the<br />
other hand, the inverters of Sunways, SolarMax, Fronius und Kaco have got a fix<br />
address allocation. The replacing devices must just be set to the address of the old<br />
device.<br />
Once the old data backup has been reimported, the system will automatically<br />
allocate the data of the former device to the replaceming device.<br />
Advice: Before a reset to factory settings we recommend to do a system and data backup.<br />
With both backups you will be able to provide the SolarLog 400e with the old settings and<br />
data if need be.<br />
The current serial number is the number permanently allocated to the SolarLog which can<br />
not be modified at all.<br />
The storing or backup interval is automatically preset based of the number of identified<br />
inverters. The SolarLog detects new measuring data every 15 seconds, these data are<br />
saved as an average in the fixed interval. If the interval is changed <strong>fr</strong>om 5 to 10 minutes,<br />
the number of minute values will double, thus the number of day curves will double as well.<br />
The larger this interval is the less detailed will be the graph.<br />
SolarLog 400e Solare Datensysteme 55
If a homepage is used for the graphic supervision (visualisation) you can set the 5 minutes<br />
interval as well with large-scale systems because the day curves will be stored for an<br />
unlimited period of time on the homepage.<br />
Date / Time<br />
The SolarLog400e is equipped with an integrated real-time clock operating for a long<br />
period of time (100 days) even in case of power failure or separation <strong>fr</strong>om the mains.<br />
If the system is connected to the internet, the clock will be readjusted every day. Thus it<br />
will never be necessary to manually adjust it. However, if a wrong date or time is indicated,<br />
it can be easily corrected or set anew. You just have to enter the desired day and time.<br />
Example: The entry for the 28.2.2007 5:31 p.m. would be: 28.02.07 17:31:00<br />
Automatic switching to summer time: thus it is not necessary to adjust it manually.<br />
Allow configuration only in your own LAN<br />
This item is only important in case of an existing internet access. Then you should tick this<br />
item in order to deny undesired access <strong>fr</strong>om the internet.<br />
Additional Password Request<br />
To deny undesired access to the configuration area you may save a password. This<br />
password will be requested at the first access to the configuration area. The SolarLog then<br />
releases the reading and modification within the configuration area. 5 minutes after the last<br />
configuration access the access will be blocked again. Then a new login in this area will be<br />
necessary.<br />
To change the password it is always necessary to enter the old password as a safety<br />
function. At the moment of delivery and after a reset to factory settings, there is no<br />
password stored in the system. In this case you do not have to enter anything under old<br />
password.<br />
56 Solare Datensysteme SolarLog 400e
Update<br />
Under this item the SolarLog 400e software may be updated.<br />
Thus it is always possible to incorporate new functions in the system or to eliminate errors.<br />
Before an update it is absolutely mandatory to make a system data and data backup.<br />
Depending on the update, a new organisation of the internal data structures may become<br />
necessary, as a result all data will be deleted.<br />
Therefore it is absolutely mandatory to save all data before!!<br />
You can call the latest updates at the internet site<br />

Homepage<br />
The SolarLog 400e offers another interesting function: The possibility to store the system<br />
data in the internet. Thus the remote query of each and any internet connection is possible<br />
and you may even present the system to your <strong>fr</strong>iends or to interested parties via this<br />
function.<br />
The homepage supervision (visualisation) is completely independent of your SolarLog 400e .<br />
Thus, you don’t need any leased line etc. and you are independent of each and any<br />
access portal.<br />
The only prerequisite is that you have got a homepage. This is an area in the internet<br />
which is available to you at your discretion. Normally the internet provider makes available<br />
the homepage <strong>fr</strong>ee of charge. Several <strong>fr</strong>ee-of-charge suppliers make available a<br />
homepage upon logon (for example: www.arcor.de )<br />
An additional prerequisite is that the homepage data can be send via FTP log.<br />
The content of the homepage, i.e. the individual pages and graphs are available under<br />
www.solare-datensysteme.de/firmware. You have just to copy the files to the homepage<br />
without any modification.<br />
Then you will just have to configure the SolarLog 400e correspondingly to ensure that the<br />
device knows whereto regularly transfer the data.<br />
To summarize the prerequisites: You just need the following to set up a SolarLoghomepage:<br />
1. a homepage<br />
2. Writting via FTP log on the homepage must be possible<br />
3. the files for the homepage<br />
4. configuration at SolarLog 400e (export)<br />
You may of course use your own system screen. To do so, you just have to replace the file<br />
„solaranlage.jpg“ by your own picture.<br />
As soon as the homepage works correctly, the „online banner“ will be automatically<br />
available. This is a small graph with brief information on the system and indication of the<br />
daily yield. The daily yield is automatically updated depending on the set up transfer<br />
interval in the dialogue „export“<br />
This banner maybe linked upon discretion in other homepages as an information. You will<br />
find the html-code in the homepage file „i<strong>fr</strong>ame.html:<br />

After the logon we will send you the access data (login) via email. You can enter these<br />
data in the SolarLog -configuration correspondingly.<br />
In this case all above-mentioned steps via FTP-programme etc. won’t be necessary. The<br />
entire homepage is already pre-configured and absolutely <strong>fr</strong>ee of charge.<br />
In addition, SMS messaging in case of problems with the system is possible. In this case<br />
we will charge you with a minor amount of money.<br />

<strong>Installation</strong> Special-RS485-PiggyBack for SMA-WR<br />
The special PiggyBack is a simple RS485 interface converter without controller and<br />
without its own "intelligence". Thanks to its simple and solid structure we can rule out any<br />
inverter disturbance. Provided that it is correctly installed in conformity with the installation<br />
prescription the technical data and features of the inverter will remain unchanged.<br />
The special PiggyBack is to be operated exclusively in combination with the SolarLog 400e .<br />
The special RS485-PiggyBacks are compatible with the inverter types<br />
− SB-SunnyBoy<br />
− SMC-SunnyMiniCentral<br />
− SWR (as of year of manufacture: 2001). Sometimes it is necessary to remove the<br />
display to insert the PiggyBack. However, the problem of available space exists as well<br />
with the original SMA-PiggyBacks.<br />
Please check the accessory for completeness:<br />
1 piece installation insulation hose for data cable<br />
1 piece Jumper<br />
1 piece screwing/bush . WR-PG 16 (M22)<br />
1 piece flat blade distributor<br />
Important Advice for <strong>Installation</strong><br />
The inverters must be opened to insert the PiggyBack interface boards. Only qualified staff<br />
will be authorized to do this work. In this respect please observe the <strong>instructions</strong> of the<br />
inverter manual.<br />
<strong>Installation</strong><br />
Before executing work at the inverter the supply voltage must be cut. First disconnect the<br />
inverter <strong>fr</strong>om the AC line then <strong>fr</strong>om the DC line. Then wait 30 minutes till all the parts alive<br />
have become discharged.<br />
Please keep in mind that there are sensitive electronic components inside the inverter and<br />
on the interface board, these components may be damaged and destroyed by electrostatic<br />
discharge.<br />

First place the PiggyBack onto the control board in the inverter. Take care that the<br />
inscription „bottom“ is readable on the board down left (see 2nd picture below).<br />

Step 2<br />
Now the individual inverters must be wired one to the other. This is done with a 4-core<br />
shielded data cable (for example 25m ring, Solare Datensysteme-Article no. 220014).<br />
Now connect all 4 contacts (2,3,5,7) of the terminal strip of inverter 1 to inverter 2 and then<br />
to inverter 3 and so on till you have connected all inverters.<br />
Terminal<br />
strip<br />
contacts<br />
2,3,5,7<br />
In case of older SMA inverters of the type SWR there may be available the 10-pole<br />
terminal strip. Connect here as well the contacts 2,3,5 and 7, the other contacts will stay<br />
unoccupied.<br />
Attention: The data cable must be led through the silicone installation bushings inside the<br />
inverter.<br />
SolarLog 400e Solare Datensysteme 65
Step 3<br />
Now you must place a terminal resistor at the last inverter. Place the jumper to the lowest<br />
position:<br />
The center and the top position must remain bare!<br />
Step 4<br />
Place jumper<br />
(right at the<br />
bottom)<br />
You will now have to wire the first inverter to the SolarLog. To do so, you may either use<br />
the data cable attached or your own cable.<br />
Pass the bare conductors through the cable opening of the inverter and then connect<br />
SolarLog Terminal strip in the inverter<br />
White (1) 2<br />
Yellow(2) 3<br />
Green (3) 5<br />
Brown(4) 7<br />
You have now finished the hardware installation. Please close the inverter and take it<br />
again into operation.<br />
Attention! Only connect the SolarLog 400e to the main supply when all inverters feed in,<br />
otherwise the system won’t identify all inverters.<br />
Now the SolarLog 400e reads the configuration data <strong>fr</strong>om the inverters. This process will take<br />
some minutes depending on the number of inverters connected. During this period, the<br />
status LED 1 is off and status LED 2 flashes. Then the data recording will start<br />
immediately.<br />
(In case not all inverters have been identified, the identification process can be restarted<br />
via the SolarLog menue item „Inverter scan/ New identify“ – see page 59)<br />
66 Solare Datensysteme SolarLog 400e
Multifunction Key<br />
The multifunction key is especially necessary to install the SolarLog. It is not required for<br />
the actual operation. To prevent wrong handling it is in countersunk and can only be<br />
operated by means of a sharp object.<br />
You can select 3 modi by this key:<br />
1. Network search mode<br />
2. New identification of inverters<br />
3. Reset to factory settings<br />
The search mode for the network is especially important for the first installation of the<br />
SolarLog. It is explained on page 7.<br />
The new identification of inverters is a helpful function in case you add new inverters to an<br />
already existing system or in case you have to replace defective inverters. Of course it is<br />
possible to call up this function via a dialogue, however, during hardware installation it is<br />
often better to directly start the new identification without the help of the PC.<br />
Reset to factory settings is often the only possibility to access to the SolarLog after a<br />
wrong and erroneous configuration. With this function the data storage and the<br />
configuration storage will be initialised anew. However, this does not reset the network<br />
address! This is to say if the SolarLog cannot be accessed in the network it won’t be<br />
necessary to do the reset to factory settings but to use the network search mode to set the<br />
address a new.<br />
Procede as follows to select the individual modes:<br />
1. First of all switch off the SolarLog, then keep the key pressed with a sharp object.<br />
2. Now switch on the SolarLog. Still keep the key pressed. At the beginning status 1<br />
and 2 are off, then status 1 and 2 will shortly flash together. Still keep the key<br />
pressed till only status 1 flashes.<br />
3. You have now entered the installation mode. By shortly pressing the key you will<br />
now move to the next mode:<br />
Mode 1 – LED 1 flashes<br />
Mode 2 – LED 2 flashes<br />
Mode 3 – LED 1 and 2 flash<br />
4. Once you have selected the desired mode you press the key again for about 5<br />
seconds till the LEDs stop flashing. Now the respective mode has been started.<br />
Mode 1 – The network area is searched. Once found, the LED 1 extinguishes and<br />
the SolarLog will restart.<br />
Mode 2 – Inverter identification is started.<br />
Mode 3 – Reset to factory settings of the SolarLog.<br />
To drop out of the installation mode you will have to cut the SolarLog <strong>fr</strong>om the electric<br />
supply for several seconds.<br />

Useful Software<br />
In the internet you will find a lot of useful software which will ease your daily work with the<br />
computer. We have prepared a list of programmes which are especially helpful when<br />
working with the SolarLog. You may use the indicated programmes <strong>fr</strong>ee of charge.<br />
Printing<br />
The SolarLog print out is activated via the internet browser print function: However, we<br />
recommend to use the following useful print programme which may be downloaded <strong>fr</strong>ee of<br />
charge under http://www.hardcopy.de because especially the graphs are not always<br />
printed completely or not at all depending on the browser used.<br />
This programme will be linked as a small symbol top right in every Window screen and<br />
with a simple mouse click you can print out the current screen content (screenshot) on a<br />
standard printer.<br />
To get a print out in the landscape format adjust it as follows:<br />
Programme configuration: „settings / options / alignment“ option „print out landscape“,<br />
„on“.<br />
