Deryk's point is a REAL important one.....

Huck the best advise I can give you is to learn to love your Maxi or Fantastic Fan.

To run AC, I would get at least 1000W of solar. At current prices, that would be expensive. A tracking array might also be a good, if expensive, idea. Size matters as well. A figure I have read is that you can expect good solar cells, under ideal conditions to make about 10 W / square foot. For 1000 W, that would be a 10' x 10' tracking array. Where do you pack that?

The prices are coming down for solar, and they are getting more efficient. So your idea is not wrong, just early. Give it a few more years.

Simple answer to the original question;

Batteries wired in parallel you add the ah rating.
Batteries wired in series the ah rating stays the same and you add the voltage.

ie; two 6v batteries in series give you 12v but the ah stays the same
or two 12v batteries wired in parallel stay at 12v but the ah is added.

Don't forget you can only use half of the amp hours listed, or risk ruining the battery. Look into marine A/C units, Mermaid come to mind. Mucho dinero, but built for 12V.

Sad to say, as I would love for all this to work with solar but this is a situation where a good generator is called for. It will be expensive for a nice quiet one but no more than all the batteries, wire, controller, panels, invertor, etc., etc. to try and make solar work. And you will have a nice gen-set for other uses like storm outages and such.

Yup Tim a generator is in your future. I have a 9000 BTU AC on my SD and my Honda 2000 runs it great. Only running half throttle max during the AC cycling on and off. One plus is that it will do that for 8 hrs 15 minutes on a full fuel load.

My problem is the Hatteras NPS campgrounds have a 9 pm curfew for generators.

I haven't seen the efficiency of energy conversion from 12VDC stored to 120VAC through the inverter required to make the A/C work. Nor the costs for that size inverter. In the end a generator will be cheaper for such a recurring load.

If you can't plug in and if genny is subject to curfew, your best bet is a couple of fans. A vent fan drawing hot air out and pulling cooler air through the windows, plus maybe another fan blowing directly on you. Can't blame you for exploring your idea, though.
