Ok had a 12 volt system in the old house. We tore it down, now going to a 24 volt system. Have 1360 watts(24v) flex panels for the roof, and about 800 watts(12v) from the old system. Went to a Outback charger, and a Magnum Inverter. The old system had 10 golf cart batteries, for about 1000 amp hours. So with it being 24 volt now, do I need to have 2000 amp hours? 1000? or 500? I would think I would need less batteries, not more but not sure! Been so long since I was on here last, had to create a new account! LOL Thanks for any advice and help folks!
