Ngokusethwa kwe-DC-coupled, i-solar array ixhuma ngqo ebhange lebhethri ngesilawuli sokushaja. Lokhu kulungiselelwa kuvamile kumasistimu angaphandle kwegridi kodwa kungashintshwa ukuze kusethwe igridi kusetshenziswa inverter yeyunithi yezinhlamvu engu-600-volt.
Isilawuli sokushaja esingu-600V sisebenzela ukubuyisela kabusha amasistimu aboshwe ngegridi ngamabhethri futhi singahlanganiswa nanoma yiziphi izikhungo zethu zamandla anezintambo zangaphambili ezingenaso isilawuli sokushaja. Ifakwe phakathi kwamalungu afanayo akhona e-PV kanye ne-inverter eboshwe ngegridi, efaka iswishi eyenziwa ngesandla ukuze iguqule phakathi kwamamodi e-grid-tie kanye ne-off-grid. Kodwa-ke, ayinakho ukuhleleka, idinga ukushintshwa ngokomzimba ukuze kuqaliswe ukushajwa kwebhethri.
Nakuba isiguquli esisekelwe kubhethri sisengakwazi ukuzenzela amandla izinto zikagesi ezibalulekile, uhlelo lwe-PV ngeke lushaje amabhethri kuze kube yilapho inkinobho yenziwe isebenze mathupha. Lokhu kudinga ukuba khona kwendawo ukuze kuqale ukushajwa kwelanga, njengoba ukukhohlwa ukwenza kanjalo kungase kuphumele ekukhanyisweni kwamabhethri angenawo amandla okushajwa yilanga.
Izinzuzo ze-DC Coupling zihlanganisa ukuhambisana nohlu olubanzi lwama-inverter angaphandle kwegridi nosayizi basebhange bebhethri uma kuqhathaniswa nokuhlanganisa i-AC. Kodwa-ke, ukuthembela kwayo ekushintsheni kokudlulisa okwenziwa ngesandla kusho ukuthi kufanele utholakale ukuze uqalise ukushaja i-PV, uma kungenjalo uhlelo lwakho lusazohlinzeka ngamandla ayisipele kodwa ngaphandle kokugcwalisa ilanga.
