Yadda ake ƙara batura zuwa tsarin hasken rana mai ɗaure grid-DC Coupling

A cikin saitin da aka haɗa DC, tsarin hasken rana yana haɗa kai tsaye zuwa bankin baturi ta hanyar mai sarrafa caji. Wannan ƙayyadaddun ƙayyadaddun tsarin tsarin kashe-grid ne amma kuma ana iya daidaita shi don saitin grid ɗin da aka ɗaure ta amfani da inverter 600-volt.

Mai sarrafa cajin 600V yana aiki don sake fasalin tsarin da aka ɗaure grid tare da batura kuma ana iya haɗa shi tare da kowace cibiyoyin wutar lantarki da aka riga aka yi amfani da su waɗanda ba su da mai sarrafa caji.
