I have mounted a small 5000 BTU air conditoner on the cab of my tractor, powered by a 2000 watt inverter. The inverter would shut down after about 90 minutes, which was better than nothing. After about 45 days of use, the inverter quit altogether.

I think i have a 75 amp alternator and I do have two 135 Amp hours marine batteries (270 AH Total). I can run approx 90 minutes before AC shuts off. Can wait an hour and go another 90 minutes or so with air.

The inverter quit working entirely, and I'm thinking about getting a new one. What might be the weak link in my set-up? What do you recommend? What size inverter and alternator do i need?

The NEC does not cover wiring in vehicles. And this appears to be a DIY post.
