I have a Residential Refrigerator and am total depressed. I chose the residential because i thought it was more efficient and it is on 120 volt.
I found the refrigerator and inverter draw about 20 amp per hour from your battery. There for letting it run for 24 hours is about 480 amps. My two 12 volt batteries are rated at 110 amps each so 220 amps. The rule I have used is only drawing liquid batteries down by 50% to prevent damage to their life. Therefor 5 hours is max with no other items drawing amperage. That is not the case because there are other draws.

So I say NO you can not run it overnight to cool it down on battery.

I do have a battery monitor so my numbers are not guesses.

Best of luck and safe travels.
