Just one battery?

[Governor Dinwiddie]

Based on what you said, that is probably the minimum you'll need. Bigger is always better. A pair of 200 Ah LiFePo batteries will be fine too.

Myself, I find that I can get by a lot of times with just a window fan on many nights. The air conditioner is going to be your biggest power hog.

I was giving ballpark back of envelope figures to get you thinking. Talk with some local folks and get their input.
