The batteries are Deka 9C12s. They're 12V each and 229AH. Golf cart batteries are 6V and in the 225AH range. 2 of the 9C12s are equivalent to 4 golf car batteries. They're 130lbs each and not cheap.
The inverter is Portawattz1000. It's a modified sine wave inverter. Not all that good. I barely used it.
The charger is a Xantrex (company name may have changed) TrueCharge40+
The battery monitor is a Link10.
I don't have a wiring diagram anywhere. But if you're in any way unsure about your ability to work with 120V systems, have someone else do this for you. Also, read your charger and inverter install documentation very carefully with respect to wiring.
I'm actually selling this popup right now. Mice got into it and chewed up spots in the brand new canvas. So I'm selling it on craigslist and getting something else and storing it elsewhere.
