Understanding Power
I've been reading up on power needs and uses, but things aren't quite clear. For starters I'm looking at the Keystone Passport 2920 BH. From what I read not all A/Cs run on DC power. How does o...

eith the proper sized inverter, running an A/C could be done using a generator to recharge during the day. It seems a bank of 4 (unknown output batteries) aren't up to the task for long enough.
I am one of the few on here who runs a/c on batteries - but only occasionally. I have 8- 80a AGMs, a 4kw inverter, 835w solar. It's a 48v system. Why 48v? Because when I tried running air at 12 or even 24v, things started heating up. Cables, connections, batteries. Yes, everything was sized properly, but the high amperage draw eventually made heat. 48v seems to work fine.
I can run my air for about an hour before the batteries start to sag, even at full solar.
You beat me to it. 8 won't be enough.
