Introduction Withthisdeviceyouhaveacquiredasolarinverterforconnectionofphotovoltaicsystemstothe grid.ThisEuropeansolarinvertercanbeusedinandisapprovedforthefollowingcountries: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, whichenablethehighestlevelsofefficiency. Thesolarinverterincludesmonitoringunits,suchasanti-islandingprotection.Thefunctionofthe anti-islandingprotection(automaticisolationpointforin-plantgenerationsystems)stipulatescom- pliance with the specifications of DIN VDE 0126-1-1, EN 50438, ENEL G.L. 12/2008, RD 1663, andcompliancewiththedirectivesforparalleloperationofpowergenerationplantsonlow-voltage gridofyourlocalutilitycompanies.Thesearedeclaredbycertificates(CECertification-see§12). -
