Yes I read that also. Its because the higher voltages allow for smaller parts. I found a 5k btu Marine 12v system that draws 45 amps 12 v dc. The compressor will cycle so its not a constant voltage. The goal is to do this as cheaply and easily as possible. I'm thinking of running a test. Put a 5k btu a/c in the trunk blowing into the cabin via the seat folded down. Running on my small generator. This would tell if its feasible. I'm pretty confident it would be enough. The next question would be where or how to find a 12 volt compressor that would work well with the current hard parts in the car. Mainly the condensing coil and evaporator coil. My current a/c is horrible. How many HP does it take to make 45 amps?
