I can find little on hooking up all my hooptie fleet to my 12v solar bank to keep the batteries topped off, especially during the winter. I have battery tenders now but would like to maintain them off the 12v side of the system. Any precautions or no no's to know? or can I just run jumpers off the system to the vehicles and they will float charge with the rest of the bank once charged? There has to be a way!
