Starcraft split AC

Is there a way for me to run the AC system of my Starcraft split AC running from bus engine to my battery bank? Thanks a lot.

Is it a belt driven system?

Yes. It's belt driven. Thanks.

Then it needs the engine to drive it. You can't run it off your batteries. It would need some type of motor or engine to turn it.

I don't know a whole lot about electric motors, but I would have to think it needs at least 12-15 hp at a certain rpm to spin that compressor. It's possible to do that, and relocate the system, but I am not sure how it would work. It would require purging the system, routing to ac lines to the new location, mounting a motor and the AC compressor(s). I also think you are looking at a 220 ac motor. It is worth research though.

If you do the math you will find that 15hp motor consuming almost 12kw of power. Figure something around a 20kw inverter to handle the startup draw.

Now figure out what size battery bank you will need to support that load.

OTR A/C systems on a bus are huge compared to what you need when you are parked. Likely 50-60k Btu compared to the 12k Btu roof air or mini split.

Battery powered A/C is a tall order. I am considering installing close to 1800 watts of solar on my 40' Bluebird to accommodate a small mini split while parked in warm sunny weather.

Now if I had the system and the money, a small diesel pony motor could handle the load. Simple set up with an Arduino if temp reaches x energize a starter solenoid, when temp reaches y energize a fuel cutoff solenoid.

Yes I am considering to install a 2 cylinder petter / onan diesel. Why on / off,... just modulate the rpm so that it cools enough, ;less noise a well.

Will low rpm affect the compressor? That would be my reasoning.
