3 Introduction
Withthisdeviceyouhaveacquiredasolarinverterforthemainsconnectionofphotovoltaicsys-
tems.Thissolarinverterischaracterizedbyitsadvancedhousingdesignandstate-of-the-artradio
frequencytechnology,whichenablethehighestlevelsofefciency.
Thesolarinverterincludesseriesmonitoringunits,suchasanti-islandingprotection,displayand
RS485(EIA485)interface.
Theinverterisusableindoorsandoutdoors.ItfulllsthedirectivesoftheVDEW(UnionofGerman
ElectricalPowerStations)forparalleloperationofpowergenerationplantsonlow-voltagenetwork
ofregionalelectricalutilitycompanies.
Thefunctionoftheanti-islandingprotection(automaticisolationpointforin-plantgenerationsys-
tems)stipulatescompliancewiththespecicationsofDINVDE0126-1-1andcompliancewiththe
low-voltageguideline.ThesearedeclaredthroughtheattachedGS-InnovacharacterandtheCE
mark(seepage60,section12).
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.

Thecontentofrenewableenergywithrespecttooverallpowerconsumptionworldwideisincreas-
ingannuallybyapprox.25%.Thereasonforthisrisecanbeprimarilyattributedtotheconstantly
increasingdemandforpower,theincreasinginterestinenvironmentallyfriendlytechnologies,as
wellastheincreasingcostsofnon-renewableenergy.
Bytheuseofrenewableenergysources,theearth‘satmospherecanbeenormouslyrelievedof
increasesinCO
2
andotherharmfulgaseswhichresultfrompowergeneration.
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mains.
ThankstoefcientMPPtracking,maximumcapacityutilizationofthesolarenergyplantisensured
evenincaseofamistyandcloudedoversky.
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.
