Are you using a smallish solar panel to charge that lot ??

yes 150 watt folding panel , when they're flat (never happens hardly) i piggy back 2

Cool, that's 12.5Amps per hour on a good day, divided by 3, So that's a nice amount to keep them topped up.

The down side to having big banks of batteries like those monsters I was going to buy adds up to 920A/h which means I would have to buy a 100 Amp charger just to charge them at the 10% rate of charge,

I was going to buy the 100w portable folding panel but the cost of it was only about $13.61c cheaper than buying 3 X 60w panels so that's why I bought the 3 60's because for the extra 13 bucks I got another 80 watts of power, :inlove: :Y:

The down side is If I add a 4th one they will only supply 20A/h and my battery bank is 345, which leaves me about 14.5 amps short. :(

You're confused about voltage RR, I've been doing this the last day and a half. :argh:

Just took out the 12 old 2 volt 1000 ah batteries and replaced them with 24 x 2 volt 550 ah batteries.

24 volt system, 2 banks of 12 x 2 volt 550 ah batteries for the house power.

Now I just have to let the solar charge them fully tomorrow before I turn the system back on.

Cheers
