The inverters convert DC current generatedby the photovoltaic modules into symmetric,single-phase (PIKO 3.0/3.6) or 3-phase (PIKO4.2/5.5/7.0/8.3/10.1) AC current and feeds this into thepublic mains grid. Power generation independent of thepublic grid (“island operation”) is not possible.Through three-phase technology, PIKO4.2/5.5/7.0/8.3/10.1 combine the stability anddurability of large central inverters with the flexibilityand high efficiency of transformer-less string inverters.The single-phase inverters PIKO 3.0/3.6 use the modernand fail-safe phase-shifting procedure to monitorthe grid.To improve efficiency, PIKO 4.2/5.5/7.0/8.3/10.1 useonly one or two phases with a limited power input (lessthan 10 percent of the rated power) for feeding currentinto the grid. The device selects the phase on a randombasis each time.The PIKO inverters are fitted with an integrated DC loadbreak switch. No external break switch is thereforerequired, unless specified by local country laws (exampleFrance). The solar modules are connected to theinverter via plug-in connectors.The PIKO inverters are available in various output sizes(see table 22, page 63) and offer you maximum flexibilityin configuring your solar energy system. This isachieved through a broad DC input voltage range,independent MPP regulators for each input, which enablethe connection of solar modules in various combinations(alignment, inclination, quantity, type). In orderto conveniently display the yields and production dataof your photovoltaic system, the inverter has an integratedweb server, see chapter 7.2.1.Note: The inverter is available in two series:small series: PIKO 3.0/3.6/4.2/5.5large series: PIKO 7.0/8.3/10.1The small series is equipped with the communicationboard I and the large series with the communicationboard II. The series have different displays (see Fig. 3and Fig. 4).Fig. 3: Display PIKO 3.0/3.6/4.2/5.5 (with communicationboard I)Fig. 4: Display PIKO 7.0/8.3/10.1 (with communicationboard II)Installation and Operating Manual for PIKO Solar Inverter 9

5 Unit and system descriptionArc recognitionArcs can occur in a PV system. These arcs can causedamage. The inverters PIKO 7.0 AD/8.3 AD/10.1 AD areequipped with arc recognitionArc typesThere are two kinds of arcs:— Serial arcs— Parallel arcsSerial arcs occur on damaged DC lines or at loose contactpoints. These arcs occur more often in PV systemsthan parallel arcs.Parallel arcs can occur between the plus and minuspole of the system or at individual sub-generators. Arcsare dangerous. For one thing they destroy the componentsupon which they occur and high temperaturescan also trigger a fire in the PV system.The arc recognition monitors the PV system for arcs. Itdetermines the string in which an arc is occurring. Thearc recognition differentiates between serial or parallelarcs. In the event of a serial arc, the inverter shuts offthe relevant string. This extinguishes the arc. A parallelarc is issued as an error message.Malfunction “Arc”When an arc occurs, the message “Malfunction arc”appears in the display. The red LED is permanently lit,the yellow LED blinks in a 5-second rhythm and a signaltone is heard. The inverter switches off the relevantstring.After 30 seconds, the inverter attempts to switch onthe relevant string again. When the inverter recognisesan arc four times within a period of 30 minutes, it shutsoff the defective string entirely.The arc recognition can be deactivated with the communicationboard II menu (default “On”). The occurringmalfunctions are recorded in the inverter.Acknowledge malfunctionThe DC break switch must be switched off and onagain in order to acknowledge the error message. Theinverter then starts normally. When an arc occurs again,the inverter behaves as previously described.Because it is not technically possible for an inverter todelete a parallel arc, this is only shown as a message inthe display. The signal tone also sounds and the redLED lights up. The message disappears in the displayonce the error message is acknowledged.Note: The entire installation of the PV system should bechecked for damage after each “Arc” malfunction.Inform your installer where appropriate.Note: In rare individual cases, false alarms can occurthat can be extinguished outside of the PV system.Causes for such false alarms can include, for example,transformer stations or large energy consumers.IMPORTANT: Under certain circumstances (e. g. withfeed cables > 60m), arcs cannot be registered. This iswhy regular maintenance of the PV system is essential.Regular inspection of the installation must be carriedout despite arc recognition!10Installation and Operating Manual for PIKO Solar Inverter

5 Unit and system description1367542Fig. 5: System illustration of a grid-connected photovoltaic system1 PV string 12 PV string 2 and 3 (optional)3 Inverter4 Electronic DC load break switchInputsThe PIKO operates using the so-called string principle:In this system, a limited number of solar modules(depending on the desired power output while consideringthe maximum permissible input voltage) are connectedin series as a string, which is then connected tothe inverter. The number of strings depends on theconfiguration of the solar energy system.The strings are connected to the inverter via plug-inconnectors.Depending on the unit type, one, two or three separatelycontrollable inputs are available. Inputs one andtwo can sometimes be connected in parallel in order toallow a higher input current (see table 3, page 18). ForPIKO 5.5, parallel connection is not possible.You can obtain the highest yields through the maximumpermissible input voltage. This is achieved by using thesmallest possible number of inputs with identicalpower. An example: For the installation of 48 solarmodules, it is better to use two inputs with 24 moduleseach rather than three inputs with 16 modules each.Be sure to always observe the specifications on thetype plate!5 AC mains cable6 Single-phase or 3-phase AC line circuit breaker(for layout, see table 2, page 18)7 Feed meterInternal consumptionAll PIKO inverters are designed in such a way that thegenerated power can be used internally in part orentirely.Control signalExternal load relayPhotovoltaic moduleInverterProductionmeterFeedmeterConsumptionmeterJumper switchConsumer devicesGridFig. 6: Possible configuration for internal consumptionThe switch output is a potential-free NO switch and candeal with a max. load of 100 mA.Note: An external load relay must be installed betweeninverters and devices.

5 Unit and system descriptionActive power and reactive power controlThe termsThere are three types of electrical power in the mainsgrid:— Active power (W)— Reactive power (Var)— Apparent power (VA)Active powerActive power is that electrical power that is convertedby an ohmic device. Ohmic devices are devices with nocoil and capacitors (e.g. heat radiators, electric stoves,light bulbs). The active power is registered by the usualelectricity meters. This means that only the activepower is calculated or paid for.The active power current is “in phase”. That means thatpower and voltage are synchronous. Both reach thezero point and the peak value at the same time.Reactive powerReactive power is that electrical power that is convertedby inductive and capacitive devices. Inductivedevices are coils. Capacitive devices are capacitors.These devices require electrical energy in order to buildup the magnetic or electrical field. This power isreferred to as reactive power. Devices with motors andcapacitors (e.g. washing machine) draw reactive powerfrom the grid.The reactive power is not registered by the usual electricitymeters. However, like the active power, it doesdraw from the power grid. The reactive power current is“out-of-phase”. That means that power and voltagereach the zero point and the peak value at differenttimes.The phase shift caused by inductive and capacitivedevices reduces the stability of the power grid andmust be compensated. The compensation of reactivepower requires electrical power. This required energymust be provided by the electricity producers at nocharge.Apparent powerApparent power is the total power, consisting of realand reactive power. The calculation of electrical powertakes place through the geometrical addition with theangular functions (cos, sin and tan).Displacement factor cosThe size of the real, reactive and apparent power canbe determined with the displacement factor cos. Thesmaller the cos factor is, the less the active powerand therefore the greater the reactive power.Note: (The cos displacement factors are set with theparameterisation software PARAKO and the size of thereactive power is defined in this way.You can acquire the software from the support.VDE application rule (VDE-AR-N 4105) andRenewable Energies Act (EEG) 2012New application rules for PV systems have applied inGermany since 1 January 2012. The VDE applicationrules (VDE-AR-N 4105) and the Renewable EnergiesAct (EEG) are compulsory. The PIKO inverters satisfythe currently required standards and guidelines.Note: Should the PV system not fulfil the RenewableEnergies Act (EEG) 2012, the grid operator can reducethe feed-in tariff or dispense with it entirely.The following points are relevant when implementingthe new application rules:— Frequency-dependent active power control— Active power control with a ripple control signalreceiver— Fixed limitation of the feed-in power to 70% of thePV output— Provision of reactive power— Regulating of unbalanced loadsFrequency-dependent active power controlTo date inverters are to be immediately disconnectedfrom the grid when they exceed the upper frequencylimit of 50.2 Hz. Grid stability can be negativelyimpacted by the abrupt switching off of large generationsystems. Hence the need for an active powerreduction solution in the event of overfrequency.This means that inverters need not be disconnectedfrom the grid when exceeding 50.2 Hz, but instead thatthe active power must be reduced. This active power isthen reduced by 40% per Hz. When the frequencyreaches 51.5 Hz, the inverter must be immediatelyseparated from the grid.12Installation and Operating Manual for PIKO Solar Inverter

5 Unit and system descriptionActive power control with a ripple control signalreceiverThe active power of the PIKO inverter can be controlleddirectly by the energy supply company via a ripple controlsignal receiver. With this technology, the generatedpower can be regulated at four levels (see Fig.7).100 %EVURegulating of unbalanced loads:In order that the power grid remains stable, it must beevenly loaded. Single-phase feed-in results in an unevenload (unbalanced load) in the grid.The maximum permitted unbalanced load measuredbetween the phases is 4.6 kVA.Note: This rule only needs to be observed when usingthe single-phase PIKO inverter. Only one PIKO 3.0 oronly PIKO 3.6 may be connected to a phase.You can get further information on this from our servicehotline (+49 (0)761 477 44 - 222).0 %60 %30 %Fig. 7: Active power control with a ripple control signalreceiverNote: For all PIKO inverters, the ripple control signalreceiver can be directly connected without an additionaldevice (see section “Connecting a ripple controlreceiver for active power control” on page 39).

Inverter configuration.2. Direct retrieval of the current yield value and/orsaved log data.3. Transferring the yield data to an solar portal.4. Remote retrieval of the current yield value and/orsaved log data.Situation 1: Configuring the inverterAll communication settings, for example, activation ofdata transfer to a solar portal, are made via the integratedweb server. To access the configuration on theweb server, you will need a computer, which must beconnected to the inverter.The inverter is equipped with an Ethernet interface(RJ45 socket) for this purpose. The computer mustalso be equipped with this type of interface. The operatingsystem is irrelevant. An Internet browser must beinstalled on the computer.You can then connect the inverter and computer eithera) via a local network (switch and Ethernet cable,see figure 24), orb) directly via a so-called crossover cable (see figure 25).Version a) is the best option when a local network isalready available. Several inverters can also be connectedin the network (figure 26).Version b) is the best option when no switch is available.Installation and Operating Manual for PIKO Solar Inverter 21

6 InstallationNote: Ethernet cables (“network cables”) are standardconnection cables commonly used for computer networks.These cables are suitable for most applicationsand available from computer specialty traders.A crossover cable is a special type of Ethernet cable forwhich the plugs are occupied differently. In this way twodevices can be directly connected to one another withouta switch or hub being necessary.You only require a crossover cable when you wish toconnect the inverter directly to a computer, meaningwithout a switch/hub (Fig. 25).1Fig. 24: Connecting inverter and computer withEthernet cables and switch1 Inverter2 Ethernet cable3 Switch/hub4 Computer (for configuration or data retrieval)123 41234 5Fig. 26: Multiple inverters in the network1 Inverter2 Additional inverters3 Ethernet cable4 Switch/hub5 Computer (for configuration or data retrieval)Situation 2: Direct retrieval of the yield dataThe retrieval of the current yield data as well as thestored inverter log data is also only possible using acomputer. The units are cabled as described undersituation 1.Alternatively, you can connect the inverters to eachother via the RS485 interface and then only need toconnect one of the inverters via Ethernet (figure 27).With this type of connection, the web server of theinverter connected via the Ethernet also displays thecurrent output data of the other inverters. However, theweb server and the stored log data are only availablefor the inverter connected via Ethernet.23Fig. 25: Connecting inverter and computer withcrossover cable1 Inverter2 Crossover cable3 Computer (for configuration or data retrieval)12345Fig. 27: Connecting inverters via the RS485 andretrieving performance data via Ethernet1 Inverter2 Additional inverters, max. 200 depending on cable length3 RS485 connection4 Crossover cable5 ComputerSituation 3: Data transfer to a solar portalThe inverter can send yield data to an Internet solarportal at regular intervals.22Installation and Operating Manual for PIKO Solar Inverter

6 InstallationTo do so,a) the inverter must be connected to a DSL router orto a network with Internet access orb) the inverter must have an integrated analoguemodem or wireless modem (GSM, available asan accessory).Version a) requires a DSL connection. If your inverter islocated close to where you already have a DSL connection,you can use the available connection for transmission.Note: If the inverters are connected to the Internet byDSL router in the local network, both direct retrieval ofthe log data as well as transmission of the log data of allconnected inverters is possible through a solar portal.Version b) with an analogue modem requires theinverter to be connected to a separate analogue telephoneconnection or an analogue extension of a telecommunicationssystem. This requires a telephoneconnection close by. The inverter must be connectedto the telephone connection at all times.For version b) with a wireless modem, you will require aSIM data card from a mobile phone provider. Theremust also be adequate wireless reception at the pointof installation.Make sure that the access point name is set correctly.To do this, use the “GSM-Link” configuration tool (seesection Installing GSM modem).A detailed description can be found on our website andthe CD provided.Note: Inadequate reception quality, for example, inareas with weak network coverage, can lead to connectionproblems and to the GSM modem dialling intothe grid too often. Depending upon the price model ofthe GSM contract, this can result in increased costs.The reception quality also depends upon weather conditions.We recommend testing the reception with anormal mobile telephone for a few days prior to installationto ensure that adequate reception is possibledespite differing weather conditions.Ensure that the antenna cable length does not exceed8 m!Note: For installations with several inverters, you willonly need one modem.Version b) with one or two invertersIf you have two inverters, you can connect them bothwith a crossover cable and equip one of the two with amodem. There is then no need for a switch or hub. Theadditional connection to a computer or a DSL router isnot an option in this case.1 2 3 4Fig. 28: Connecting two inverters with a crossovercable, transferring data via modem1 Inverter (without modem)2 Inverter with an integrated modem (analogue or GSM)3 Crossover cable4 Telephone connection box or mobile communicationsantenna (depending on the modem being used)Version b) with two or more invertersTo transfer data from several inverters to a solar portalvia modem, first connect the inverter to a switch/hubvia an Ethernet cable. You will only need one modem:the inverter with the modem then assumes the functionof a router for the other inverters.The number of network connectable inverters is in principleonly limited by the available IP addresses. In practice,for data transfers via GSM or analogue modem, amax. of 30 inverters can be networked, for data transfersvia DSL, a max. of 300 inverters can be networked.16234 5WWWWWWFig. 29: Connecting several inverters through theEthernet and transferring data via modem1 Inverter with an integrated modem (analogue or GSM)2 Additional inverters (without a modem), max. 293 Ethernet cable4 Switch/hub5 Computer (for configuration and, if applicable, directretrieval)6 Telephone connection box or mobile communicationsantenna (depending on the modem being used)Installation and Operating Manual for PIKO Solar Inverter 23

6 InstallationSituation 4: Remote retrieval of yield dataYou can also connect to the inverter remotely instead ofthrough a local network. This may possibly involveadditional connection costs.Similar to situation 3, the inverter must eithera) be connected to a DSL router orb) have a modem (analogue or GSM) installed.Version a) Inverter with DSL connection to theInternetTo ensure the inverter can actually be accessed via theInternet, several requirements must be met.— The inverter must have a fixed IP address in thelocal network.— Port forwarding must be configured to the inverterIP address in the router.— The router must be assigned a fixed IP address bythe Internet provider or you must register the routerwith a DynDNS service to connect the dynamicrouter IP address with a fixed name.The inverter can then be accessed over the Internetunder the domain name provided by the DynDNSservice, and you can connect to the inverter withany Internet browser (see figure 30).Setting up a port forwarding and a DynDNS service cannot be illustrated in detail here due to the vast numberof different devices and services available.Note: DynDNS services can also be found under thedesignation “Dynamic DNS” and “DNS-Host-Service”.In order that the router can be reached under theselected domain name, it informs the DynDNS serviceof each IP address change. Many of the available routersoffer such a function, but a router generally onlysupports certain DynDNS services.With some router manufacturers the function for portforwarding is called “Virtual Server” or similar.For further information see the operating instructions ofthe router.Fig. 30: Retrieving log data: Inverter connected to theInternet via DSL1 Inverter2 DSL router3 Internet4 Computer5 Internet-compatible mobile phone with browser functionVersion b) with an integrated modemAn inverter connected to the telephone network by ananalogue modem can only be contacted by a computerwhen the computer establishes the connection viaan analogue telephone connection or via the analogueconnection of a telecommunications system (dial-inconnection, see figure 31).1 221WWWFig. 31: Retrieving log data: Inverter connected to atelephone network1 Inverter with integrated analogue modem2 Telephone socket3 Telephone network4 Computer with modem334245Dialling in with a computer and analogue telephoneconnection does not function reliably for an inverterwith GSM modem.

The units are cabled as described undersituation 1.Alternatively, you can connect the inverters to eachother via the RS485 interface and then only need toconnect one of the inverters via Ethernet (figure 43).With this type of connection, the web server of theinverter connected via the Ethernet also displays thecurrent output data of the other inverters. However, theweb server and the stored log data are only availablefor the inverter connected via Ethernet.11 Inverter2 Additional inverters, max. 200 depending on cable length3 RS485 connection4 Ethernet/crossover cable5 ComputerSituation 3: Data transfer to a solar portalThe inverter can send yield data to an Internet solarportal at regular intervals.To do so,23243 4Fig. 43: Connecting inverters via the RS485 andretrieving performance data via Etherneta) the inverter must be connected to a DSL router orto a network with Internet access or5b) the inverter must have an integrated analoguemodem or wireless modem (GSM, available asan accessory).Version a) requires a DSL connection. If your inverter islocated close to where you already have a DSL connection,you can use the available connection for transmission.Note: If the inverters are connected to the Internet byDSL router in the local network, both direct retrieval ofthe log data as well as transmission of the log data of allconnected inverters is possible through a solar portal.Version b) with an analogue modem requires theinverter to be connected to a separate analogue telephoneconnection or an analogue extension of a telecommunicationssystem. This requires a telephoneconnection close by. The inverter must be connectedto the telephone connection at all times.For version b) with a wireless modem, you will require aSIM data card from a mobile phone provider. Theremust also be adequate wireless reception at the pointof installation.Make sure that the access point name is set correctly.To do this, use the “Settings” page (seesection Installing GSM modem) via the “GSM-Link”configuration tool.You will find a detailed description on our website.Note: Inadequate reception quality, for example, inareas with weak network coverage, can lead to connectionproblems and to the GSM modem dialling intothe grid too often. Depending upon the price model ofthe GSM contract, this can result in increased costs.The reception quality also depends upon weather conditions.We recommend testing the reception with anormal mobile telephone for a few days prior to installationto ensure that adequate reception is possibledespite differing weather conditions.Note that the antenna position depends on themaximum cable length of the GSM antenna of 8 m!Note: For installations with several (max. 30) inverters,you will only need one modem.Version b)To transfer the data of several inverters to a solar portalwith a modem, first connect the inverter with the Ethernet-crossovercable. You will only need one modem:the inverter with the modem then assumes the functionof a router for the other inverters.The number of network connectable inverters is in principleonly limited by the available IP addresses. In practice,for data transfers via GSM or analogue modem, amax. of 30 inverters can be networked, for data transfersvia DSL, a max. of 300 inverters can be networked.Installation and Operating Manual for PIKO Solar Inverter 29

This may possibly involveadditional connection costs.Similar to situation 3, the inverter must eithera) be connected to a DSL router orb) have a modem (analogue or GSM) installed.Version a) Inverter with DSL connection to theInternetTo ensure the inverter can actually be accessed via theInternet, several requirements must be met.— The inverter must have a fixed IP address in thelocal network.— Port forwarding must be configured to the inverterIP address in the router.— The router must be assigned a fixed IP address bythe Internet provider or you must register the routerwith a DynDNS service to connect the dynamicrouter IP address with a fixed name.The inverter can then be accessed over the Internetunder the domain name provided by the DynDNSservice, and you can connect to the inverter withany Internet browser (see figure 45).Setting up a port forwarding and a DynDNS service cannot be illustrated in detail here due to the vast numberof different devices and services available.Note: DynDNS services can also be found under thedesignation “Dynamic DNS” and “DNS-Host-Service”.In order that the router can be reached under theselected domain name, it informs the DynDNS serviceof each IP address change. Many of the available routersoffer such a function, but a router generally onlysupports certain DynDNS services.With some router manufacturers the function for portforwarding is called “Virtual Server” or similar.For further information see the operating instructions ofthe router.30Installation and Operating Manual for PIKO Solar Inverter
