Using Power Inverter to Run Air Con?

I've you're camping where the humidity is low, (it's only 5% here today), you can use one of these.

Turbokool Evaporative Cooler

It runs on 12v. I use a monster one to cool my house. Works very well and economically.

Possible, but not practical.

To make 2000 Watts with DC takes 10+ times the Amps as AC. You would need a 12V DC source capable of producing 160 Amps continuous. That's assuming the conversion is 100% efficient, which it isn't. Try more like 180-200 Amps.

That's the full output of two "heavy duty" automotive alternators, and you can't run an automotive alternator at its full "rated" output for extended periods or it will melt down. You'd have to rig up 3-4 alternators in your tow rig.

Sounds like you want the AC running while you travel? Why? Are you so fragile in constitution that you can't put up with it being a little stuffy in the camper for an hour or so after you arrive somewhere?

It's going to take you some time to set up, so why not plug in and fire off the AC as soon as you're parked, then do your setup routine? By the time you're deployed and ready to sit down and relax in some nice cool AC, it will be ready for you.

Every thread I have read on this subject would indicate that it's possible but not very practical.

Best to use a sine wave inverter and you will need a couple dozen botteries for a decent run time.
Better to just run the generator or enjoy the heat with some cool water.
