some super quick math.
lets assume your AC draws 10a at 120v, and runs for 4 hours. That's 10a x 120v x 4h = 4800Wh.
In batteries, figure each 6v golf cart style battery has roughly 100ah x 6v to give in normal usage, that's 600Wh. You'd need 8 6v batteries (at ~65# each, so 520 pounds of lead) to get up to 4800Wh.
Seems totally doable! :B
Wow. THAT I didn't know. I don't think I'm friendlier to the idea of hauling over 500 lbs of lead and I shudder to think of how many solar panels mounted on the roof. I think my poor van would wind up looking like a rolling science experiment.
I'll keep looking for alternatives. For now, I'll stick to a fantastic fan in the roof and a propane genny.
Thanks, everybody for the answers!
