3 Introduction
Withthisdeviceyouhaveacquiredasolarinverterforconnectionofphotovoltaicsystemstothe
grid.ThisEuropeansolarinvertercanbeusedinandisapprovedforthefollowingcountries:Ger-
many, France, Spain, Italy, Portugal, Greece, Czech Republic and Belgium. The solar inverter
ischaracterizedbyitsadvancedhousingdesignandstate-of-the-arthigh-frequencytechnology,
whichenablethehighestlevelsofefciency.
Thesolarinverterincludesmonitoringunits,suchasanti-islandingprotection.Thefunctionofthe
anti-islandingprotection(automaticisolationpointforin-plantgenerationsystems)stipulatescom-
pliancewiththespecicationsofDINVDE0126-1-1,EN50438,ENELG.L.12/2008,RD1663,
andcompliancewiththedirectivesforparalleloperationofpowergenerationplantsonlow-voltage
gridofyourlocalutilitycompanies.Thesearedeclaredbycerticates(CECertication-see§12).
Theinverterisusableindoorsandoutdoors(IP65).
Inthefollowingtechnicaldescription,theprecisefunctionsareexplainedtotheinstaller,aswell
astheuser,whicharerequiredfortheinstallation,operationalstart-upandhandlingofthesolar
inverter.
4 System
Thesolarinverterconvertsdirectcurrentfromthesolarcellsintoalternatingcurrent.Thisenables
youtofeedyourself-producedsolarenergyintothepublicgrid.
ThankstoefcientMPPtracking,maximumcapacityutilizationofthesolarenergyplantisensured
eveninthecaseofcloudyskyconditions.
ThestringconceptmeansthatPVmodulesarealwaysconnectedinseries(inastring)and/orthat
stringswiththesamevoltageareconnectedinparalleltothesolarinverterwiththeaimofsigni-
cantlyreducingthephotovoltaicsystem’scablingrequirements.
Thefactthatthemodulesareconnectedinstringsalsomeansthatthephotovoltaicsystemcanbe
perfectlymatchedtothesolarinverter’sinputvoltagerange.
4.1 Data evaluation and communication
Theintegrateddatadisplay,processingandcommunicationofthedeviceenableseasyoperationof
thesolarinverter.Monitoringoftheoperationalstatusandsignalingofoperationalfailuresareca-
pableofbeingcalledupoverthedevicedisplay.Thedatainterfaceenablesthedownloadingofdata
whichcanbeevaluatedwithaPCsystemandguaranteescontinuousrecordingofoperatingdata.
Thebestwayofaccessingthisfunctionalityisviatheavailableaccessories(e.g.WEB´log);com-
prehensiveandseamlesssolarinvertermonitoringisensured.
Thedataread-outovertheintegratedinterfaceandthedisplayispossibleonlyinsolaroperation.

4.2 Technical structure of the solar inverter
AgalvanicalisolationofthesolarinverterfromthegridisachievedthroughaDC/ACconverterwith
anintegratedhigh-frequencytransformer.Thephotovoltaicvoltageisadjustedsothatthemaximum
poweroutputofthePVmodulesisalsoachievedwithvaryingsolarirradiationlevelsandtempera-
tures(MPP-Tracking).
TheMPPrangeofthesolarinverterisbetween150Vand450V.ThisfacilitatestheuseofPV
modulesbyavarietyofmanufacturers.Measuresmustbetakentoensurethatthemaximumopen-
circuitvoltageof540VDCisneverexceeded.Pleasenotethatthemaximumopen-circuitvoltage
will occur at the lowest temperatures anticipated. You will nd more detailed information about
temperaturedependencyinthedatasheetofthePVmodules.Thedevice’spowerconsumptionis
kepttoaminimum.
Thehigh-qualityaluminumcasingcorrespondstoprotectionclassIP65(water-jet-proofanddust-
proof)andisprotectedagainstweatheringprocessesbysurfacerenement.Thecoolingcharac-
teristicproleisdesignedsothatoperationoftheinverterispossiblewithambienttemperatures
from-25°Cto+70°C.
Acoolingcharacteristicproleisusedfortheremovalofthepowerdissipationcausedthroughthe
voltage conversion.An internal temperature control protects the device against excessive tem-
peraturesintheinteriorofthesolarinverter.Incaseofhighambienttemperatures,themaximum
transferablepowerislimited.
Thesolarinverteriscontrolledbymicrocontrollers,whichalsoimplementinterfacecommunication
andthemonitoringofvaluesandmessagesonthedisplay.
Twoindependentandredundantmicrocontrollerscontrolthemonitoringofthegrid,whichiscon-
sistentwiththefeed-indirectivesofyourlocalutilitycompanyandDINVDE0126-1-1,EN50438,
ENELG.L.12/2008andRD1663(anti-islandingprotection).Thisenablesaninstallationofthesolar
inverterinthein-houseelectricalgrid.
OperatorprotectionrequirementsaremetbyelectricallyisolatingthegridfromthePVmodule.The
electricalisolationbetweenthegridandthePVmoduleisequivalenttobasicinsulation.Maximum
operatorprotectionisensuredbyreinforcedisolationbetweenthegrid,PVmodulesandaccessible
interfaces(displayandRS485interface).Relevantstandardsconcerningelectromagneticcompat-
ibility(EMC)andsafetyarefullled.
Thesolarinverterisfunctionalinon-gridoperationexclusively.Anautomatedisolationpoint,which
isapprovedbyacerticationagency,guaranteessecuredisconnectionincaseofcircuitisolationor
interruptionsinpowersupplyandavoidsisolatedoperation.
Thedisconnectionequipmentallowsforautomaticisolationforin-plantgenerationsystemsofnomi-
nalpower≤4.6kVA,withsingle-phaseparallelfeed-inthroughthesolarinverterintothepublicgrid.
