5000w Inverter For Roof A/C

Recommended Posts

Has anyone tried a good 5000w inverter to power a roof ac while traveling down the road?

Would it be too much strain on the alternator or the batteries?

Just curious. :)

The answer is that to use the setup you are suggesting will never work. While a 2000 watt inverter would easily run one rooftop ac, 2000 watts divided by 120 volts equals 16.666+ amps output. But the draw against a 12 volt system

will be roughly 14 times the 16.66 = 233.24 amps just to run the ac continuous . Still too many amps against a normal 12 volt system.

Only way would be to use a 24 volt system complete with it's own 24 volt alternator and of course the inverter will need to be 24 volts, then the amp draw will still be about 115 amps against the 24 volt system.

So as said above, run your generator to keep cool, or have a pocket full of money.
