No external break switch is therefore required,unless specified by local country laws (exampleFrance). The solar modules are connected to theinverter via plug-in connectors.In order to conveniently display the yields and productiondata of your photovoltaic system, the inverter hasan integrated web server, see chapter 8.6.1.The PIKO solar inverter is a powerful and transformerlessstring inverter. It converts direct current generatedby the photovoltaic modules into symmetrical, singlephasealternating current and supplies it to the publicpower grid. Power generation independent of thepublic grid (island operation) is not possible.01/2013 | 10229868 | Operating manual for PIKO inverter 3.0 9

7 Unit and system description125643Fig. 5: System illustration of a grid-connected photovoltaic system1 PV string 12 Inverters3 Electronic DC switch4 AC mains cable5 Single-phase AC line circuit breaker6 Feed meterInputsThe 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 upon theconfiguration of the solar system.The strings are connected to the inverter with plug-inconnectors.Always note the specifications on the type plate!Internal consumptionThe PIKO inverters are designed in such a way that thegenerated power can be used internally either entirelyor in part.Control signalExternal load relayPhotovoltaic moduleInverterProductionmeterFeedmeterConsumptionmeterJumper switchGridNote: An external load relay must be installed betweeninverters and devices. No devices may be connecteddirectly to the inverter!You can find the description for the electrical connectionin section “Connect switch output (S0/Al OUT)” onpage 26.You can find the description of the S0 output configurationfor the control of internal consumption in section“Setting the switch output function” on page 31.Active 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". This means thatcurrent and voltage are synchronous. Both reach thezero point and the peak value at the same time.Consumer devicesFig. 6: Possible configuration for internal consumptionThe switch output is a potential-free NO switch and candeal with a max. load of 100 mA.1001/2013 | 10229868 | Operating manual for PIKO inverter 3.0

7 Unit and system descriptionReactive 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 usualelectricity meters. However, like the active power, itdoes draw from the power grid. The reactive powercurrent is "out-of-phase". That means that power andvoltage reach the zero point and the peak value atdifferent times.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 displacement factor cos can be set withthe parameterisation software PARAKO in order todefine the magnitude of the reactive power.You can acquire the software from 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.Active power control with a ripple control signalreceiverThe active power of the PIKO inverter can be controlleddirectly by the energy supply company via a ripplecontrol signal receiver (1). With this technology, thegenerated power can be regulated at four levels(see Fig.7).10 %100 %60 %30 %EVUFig. 7: Active power control with a ripple control signalreceiverNote: For all PIKO inverters, the ripple control signalreceiver can be directly connected without anadditional device (see section “Connecting a ripplecontrol receiver for active power control” on page 27).The regulating function is activated in the web server ofthe inverter (option "Function of analogue inputs: activepower control").01/2013 | 10229868 | Operating manual for PIKO inverter 3.0 11

8 InstallationFixed limitation of the feed-in power to 70% of thePV outputShould the active power control not be realisable with aripple control signal receiver, the feed-in power is thengenerally to be reduced to 70% of the PV generatoroutput according to the Renewable Energies Act 2012(EEG 2012).The reduction is carried out with the parameterisationsoftware PARAKO.Provision of reactive powerAs of a system apparent power of 3.68 kVA, the energyprovider must release a part of the generated power asreactive power.With the parameterisation software PARAKO, thereactive power can be specified as follows:cos A value for cos is prescribedcos (P)An active power curve is prescribedTable 5: Reactive power control with PARAKOIn addition, the displacement factor cos can beremote-controlled through a ripple control signalreceiver. Configuration to this purpose is also to becarried out with PARAKO.Regulating of unbalanced loads:In order that the power grid remains stable, it mustbe evenly loaded. Single-phase feed-in results in anuneven load (unbalanced load) in the grid.The maximum permitted unbalanced load measuredbetween the phases is 4.6 kVA.Note: When several PIKO 3.0 inverters are used, theinverters must be operated at different phases.You can get further information on this from our servicehotline (+49 (0)761 477 44 - 222).8 InstallationDANGERRisk of death due to electrical shock!When performing any work on the inverter and feedcables:• De-energise the AC and DC sides of the device,see chapter 9.4 ‹Switching the inverteroff/decommissioning›.• Secure the voltage supply from being unintentionallyswitched back on.• Wait at least five minutes until the capacitors of theinverter have discharged.• Check the device and cables to make certain thatthey are voltage-free.• Prior to installation, check whether the local mainsgrid and the power output of the photovoltaicmodules are compatible with the technical data ofthe inverter. Observe the type plate.• Observe the specified sequence of installationtasks: Install the inverter first, then connect it to theelectricity supply.• Observe all national regulations in the country ofuse as well as the connection and safety regulationsof the local energy supplier.• Pay attention to careful and correct installation: Nodirt, no foreign bodies and no moisture may enterthe inverter.1201/2013 | 10229868 | Operating manual for PIKO inverter 3.0

8 Installation• Switch off the current distributor and secure thevoltage supply from being unintentionally switchedback on. Ensure that the current distributor is deenergised.• Lay the mains cable from the inverter to the currentdistributor.• WARNING! Risk of fire due to overcurrent andheating of the mains cable. Note the cable crosssectionsand the information about the line circuitbreaker. Install a line circuit breaker 16 A into themains cable between the inverter and the feedmeter to secure it against overcurrent.• Do not switch on the voltage yet.8.4 Earth connection (only for France)For connection in France, the inverter must be earthedas shown in the following illustration.8.5 Connecting the DC side3 NmFig. 15: Earth connection (only for France)The number of strings to be connected depends on theconfiguration of the photovoltaic system.The cross-section of the DC cables should be as largeas possible, a maximum of 4 mm² for flexible cablesand 6 mm² for rigid cables. We recommend using tinplatedcables. If non-tin-plated cables are used, thecopper strands may oxidise as a result of which thetransition resistance of the crimp connections will betoo high.The delivery package of the inverter includes plug-inconnectors from Multi-Contact (type MC4).During assembly, always observe the latestspecifications from the manufacturer of the plug-inconnectors, e.g. regarding required special tools,permissible tightening torques etc.Further information is available, for example, online atwww.multi-contact.com.Installing the plugs onto the DC cablesDANGERRisk of death due to electrical shock!The PV lines may be live when the PV field is irradiated.• Ensure that the DC switch is set to O (OFF).The plug-in connectors may be plugged in anddisconnected in this position only.• Eliminate any existing earth faults or short circuitsin the strings.• Remove 6–7.5 mm of insulation from the DCcables. Be careful not to cut any individualconductors.• Crimp the DC cables according to therecommendations of the plug-in connectors'manufacturer.• Lead the crimped contacts from behind into theplug or socket insulation until they engage.Make sure to use the correct counterparts forthe plug-in connector couplings on the inverter.Observe the polarity of the cables.• Pull gently on the cable in order to check whetherthe metal part has engaged.• Check that assembly has been carried out inaccordance with the recommendations of theplug-in connectors' manufacturer.• Hand-tighten the cable connections.

8 Installation8.6.1 Connecting to the web server ofthe inverter• Connect the inverter with a computer as describedin chapter 8.6.• Set the Ethernet interface (TCP/IP protocol) of thecomputer so that the IP address automaticallyobtains the DNS server address. To alter thissetting, administrator access rights may berequired.• Start your Internet browser and enter the letter Sand the serial number of the inverter in the addressbar, for example http://S12345FD323456➜ The log-in window opens.• Enter user name and password. The factorydefaults for user name and password are set asfollows:• Confirm the entries by clicking on "OK".➜User name: pvserverPassword: pvwrThe main page of the inverter is displayed.Overview of the communications interfacesIn terms of communication options, four differentsituations are taken into account.1. Inverter configuration.2. Direct retrieval of the current yield/output valuesand/or saved log data.3. Transfer of the yield/output data to an Internet solarportal.4. Remote retrieval of the current yield/output valuesand/or saved log data.Situation 1: Configuring the inverterAll settings relating to communication, for example,activation of data transfer to a solar portal, can beselected directly via the display or the integrated webserver. In order to access the web server for configuration,you require a computer that is connected to theinverter either directly or via the network.The inverter is equipped with two Ethernet interfaces(RJ45 sockets) for this purpose. The computer mustalso be equipped with this type of interface. The operatingsystem is irrelevant, as the web server is called upvia an Internet browser (e.g. Mozilla Firefox, MicrosoftInternet Explorer).You can then connect the inverter and computer eithera) directly via an Ethernet cable (see illustration 21) orb) via a local network (switch/hub/router and Ethernetcable, see figure 22).Version a) is the best option when no switch isavailable.Version b) is the best option when a local network isalready available. Several inverters can also beconnected in the network (figure 20).Fig. 19: Main page of the web server1801/2013 | 10229868 | Operating manual for PIKO inverter 3.0

The units are cabled asdescribed under situation 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 23).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.123412Fig. 21: Connecting inverter and computer withEthernet cable1 Inverters2 Ethernet/crossover cable3 Computer (for configuration or data retrieval)35Fig. 23: Connecting inverters via the RS485 andretrieving performance data via Ethernet1 Inverters2 Additional inverters, max. 200 depending on cable length3 RS485 connection4 Ethernet/crossover cable5 Switch/hub6 Computer6123 4Fig. 22: Connecting inverter and computer withEthernet cables and switch1 Inverters2 Ethernet/crossover cable3 Switch/hub4 Computer (for configuration or data retrieval)01/2013 | 10229868 | Operating manual for PIKO inverter 3.0 19

8 InstallationSituation 3: Data transfer to a solar portalThe inverter can send yield data to an Internet solarportal at regular intervals.To do so,a) the inverter must be connected to a DSL router orto a network with Internet accessorb) 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 the building and you already have aDSL connection, you can use the available connectionfor transfer.In the case of data transfer via DSL, a max. of300 inverters can be networked.Note: If the inverters are connected to the Internet byDSL router in the local network, both direct retrieval ofthe log data as well as transfer of the log data of allconnected inverters is possible through a solar portal.Version b)To transfer the data to a solar portal with a modem, firstconnect the inverter via the Ethernet/crossover cable.You will only need one modem: the inverter with themodem then assumes the function of a router for theother inverters.Version b) with an analogue modem requires theinverter to be connected to a separate analoguetelephone connection or an analogue extension of atelecommunications system. 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 willrequire a SIM card from a mobile phone provider. Theremust also be adequate wireless reception at the pointof installation.Make sure that the APN (access point name) is setcorrectly. To do this, use the "Settings" page in the"GSM-Link" configuration tool (see section InstallingGSM modem).You will find a detailed description on our website.The reception quality is also affected by the weather.We recommend testing the reception with a normalmobile telephone for a few days prior to installationto ensure that adequate reception is possible despitediffering weather conditions.Note that the antenna position depends on themaximum cable length of the GSM antenna of 8 m!The number of inverters that can be connected to anetwork is principally only limited by the available IPaddresses. In practice, a maximum of 30 inverterscan be networked when transferring data via GSMor analogue modem.1523WWWFig. 24: 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/crossover cable4 Computer (for configuration and, if applicable, directretrieval)5 Telephone connection box or mobile communicationsantenna (depending on the modem being used)Note: For installations with several (max. 30) inverters,you will only need one modem.4ATTENTIONInadequate reception quality, e.g. in areas with weaknetwork coverage, can lead to connection problemsand to the GSM modem dialling into the grid toooften. Depending on the price model of the GSMcontract, this can result in increased costs.2001/2013 | 10229868 | Operating manual for PIKO inverter 3.0

8 InstallationSituation 4: Remote retrieval of yield dataYou can also connect to the inverter remotely insteadof through 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 25).Setting up a port forwarding and a DynDNS servicecan't 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.
