Doubtful that your 1000w inverter will be enough to power the AC through the locked rotor draw of the compressor. If it could, the 430w would drain a single battery very fast, that is a 40 amp draw. Assuming you have a 80AH starting battery, you would be dead in less than an hour or two. It's also doubtful that the alternator would work in this situation since it would be maxed out and won't last when asked to do that.
"locked rotor draw of the compressor"??? i'm not sure what you are saying? i have run the a/c unit off my 1000w xantrex inverter tied to four 6v golf cart batteries with no problem.
yes, it would drain the starter battery very quickly, which is why i would only run it while driving.
indeed,the alternator is my concern. but why wouldn't a 100 amp charging system be able to handle the ~40 amp draw, especially if i wasn't running headlights?
