I-DC Fuse isetyenziswa ikakhulu kwibhokisi yokudibanisa ye-DC kwiinkqubo ze-solar PV.Xa iphaneli ye-PV okanye i-inverter ibangele ukugqithiswa okanye isiphaluka esifutshane, sihamba ngokukhawuleza, ukukhusela iiphaneli ze-PV, i-fuse ye-DC isetyenziselwa ukukhusela ezinye iindawo zombane kwisekethe ye-DC, xa i-overload okanye isiphaluka esifutshane.
