Kwi-DC-coupled setup, i-solar array idibanisa ngqo kwibhanki yebhetri ngokusebenzisa umlawuli wentlawulo. Olu lungelelwaniso luqhelekile kwiinkqubo ezingaphandle kwegridi kodwa lunokulungiselelwa ukuseta okubotshwe kwigridi kusetyenziswa isiguquli somtya we-volt angama-600.
Isilawuli sentlawulo ye-600V sisebenzela ukubuyisela kwakhona iisistim eziboshwe ngegridi kunye neebhetri kwaye zinokudityaniswa nawo nawaphi na amaziko ethu ombane afakwe ngaphambili angenawo umlawuli wentlawulo. Ifakwe phakathi koluhlu olukhoyo lwePV kunye negridi-ebotshwe inverter, ebonisa iswitshi yesandla yokuguqula phakathi kwegridi-tie kunye ne-off-grid modes. Nangona kunjalo, ayinakucwangciswa, ifuna ukutshintsha ngokomzimba ukuze kuqalise ukutshaja ibhetri.
Ngelixa isiguquli esekwe ebhetrini sisenokwenza ngokuzimeleyo izixhobo zombane eziyimfuneko, uluhlu lwePV aluyi kuhlawulisa iibhetri de isitshixo sisebenze ngesandla. Oku kufuna ubukho bendawo ukuze uqalise ukutshaja ngelanga, njengoko ukulibala ukwenza oko kunokukhokelela ekukhutshweni kweebhetri ezingenakho ukutshaja ngelanga.
IiPros ze-DC Coupling ziquka ukuhambelana noluhlu olubanzi lwee-inverters ze-off-grid kunye nobukhulu bebhanki yebhetri xa kuthelekiswa nokudibanisa kwe-AC. Nangona kunjalo, ukuthembela kwayo kutshintshiselwano lwezandla kuthetha ukuba kufuneka ubekhona ukuze uqalise ukutshaja i-PV, ukuba kusilele apho inkqubo yakho iya kubonelela ngamandla okugcina kodwa ngaphandle kokuzaliswa kwakhona kwelanga.
