My rig has twin a/c and draw about 30 amp while running. Founds lots of 48-66 volt/4000watt ranged invertors for decent prices. At 60 volts the amps are way low around 66 ish which is 12ish per battery which sounds good to me. With 500 ah can probaly get 2-4 hours runn time on a/c?? Depending on how hot it is? Might be crazy, but i could grab a small 2000 honda gen and use that to charge each of the 5 batteries individually with dedicated chargers. The intial cost of getting five decent 10 amp chargers is about 400$ bucks but all well, it is what it is. My main goal was to have some type of ability to have a/c at night while camping at state camp grounds that do not have electric. Thaanks !!
