I have solar panel problem?
I have two 80 watt mono crystalline panels in fixed position of approx 20 degrees incline from horizontal and facing south. I have removed the charge controllers and hard wired straight on to two 90amp batteries. They will not keep my 12v fridge going, it needs approx 20 amps per day. They never get the batteries above 11.8v. No load voltage is 20v ish short circuit currant 3.8amp in good sunlight no flow back so diodes seem to be working. Nearly new batteries. What do i check next? cheers Andre
i think you should check whole circuit!
