Kunezinhlobo ezimbalwa zezixhumi ze-PV ezitholakalayo namuhla.Lezi zixhumi zitholakala kumamojula amahle nebi futhi zisetshenziselwa ukuxhuma amamojula abe yizintambo zochungechunge.Izixhumi ze-PV nazo zisetshenziselwa ukwakha i-DC home-run to the inverter.Kuzinhlelo ezisebenzisa izilungiseleli ze-DC noma ama-microinverters, izixhumi ze-PV zisetshenziselwa ukuxhuma imojuli kudivayisi yeleveli yemojuli.
Ukugcina ukuthobelana kwekhodi kubalulekile ukuthi izixhumi ze-PV zilinganiselwe nge-UL ukuze zinqamuke.Eminyakeni yamuva nje, lokhu bekudinga ukucatshangelwa kusengaphambili njengoba iningi lamamojula avela efekthri anezixhumi ezivamile ezifana ne-Staubli MC4 noma i-Amphenol.Ushintsho luyeza.Namuhla abakhiqizi abaningi bamamojula baphendukele kuzixhumi ezijwayelekile ze-PV.Ngaphezu kwalokho, ezinye izihlanganisi zezintambo namabhokisi ezintambo ze-inverter DC manje anikezwa ekucushweni okunezintambo zangaphambili nezixhumi ze-PV esezivele zikhona.Nakuba lezi zixhumi zihlangene ngokugcwele nazoI-MC4futhiI-AmphenolOzakwethu be-H4, ezimweni eziningi inyunyana phakathi kwalezi zixhumi AKUKHO ukuxhumana okulinganiselwe nge-UL.Abahloli abaningi sebeqalile ukuqaphela lokhu kushayisana okuphoqa osonkontileka ukuthi bathole isisombululo.
Izixhumi ze-PV ezakhayo kanye nemodeli zivame ukufakwa ohlwini kumamojula wedatha yamashidi.Uma ubona “i-MC4 iyahambisana” kusho ukuthi cishe usebenzelana nesixhumi esijwayelekile
Ukugcina uxhumano lwe-PV olulinganiselwe ngekhodi nge-UL unezinketho ezimbalwa.Uma isistimu isebenzisa isiguquli sezintambo esijwayelekile ikhambi elilula kakhulu ku-conundrum yesixhumi ukuthenga izixhumi ezengeziwe (noma iziswebhu ezinezintambo zangaphambili) ukuze zifane nezixhumi ezitholakala kumamojula.Umphathi we-akhawunti yakho angakusiza ekuboneni nasekutholeni lezi zixhumi.Lezi zixhumi ezengeziwe zizosetshenziselwa ukugcina uxhumano olulinganiselwe nge-UL ekugijimeni kwakho kwasekhaya kwe-DC.
Uma ukhetha ungathengi izixhumi ezengeziwe ze-PV ezejwayelekile abanye abakhiqizi bazohlinzeka ngesengezo sewaranti esivumela ukususwa kwezixhumi zefekthri ze-PV.Izixhumi ozikhethayo zingase zibecrimpedkumamojula iziswebhu.Uma ukhetha leli su imikhondo kuphela ekunqanyulweni kweyunithi yezinhlamvu ezingadinga ukushintshwa.
