alright, my neighbor has a commercial grade cooler, a delfield 4448N-18M in his trailer. is it possible to power it off of DC power up to 10 hours with a large enough inverter and multple batteries? and if so, how? if not, any other ideas besides a gas powered generator if the trailer has to be stand alone?
thanks in advance, i am just so not good with electrical issues

the draw is 8.11kwh daily

I would honestly say that you need a generator.
You would probably need at least a 3000w inverter and like 6 large capacity marine batteries to run it for that long.

8.11 kWh per day (24 hours) equals out to 337W of power draw, well within the capabilities of a reasonably small inverter (say perhaps a 450W inverter).
Still, that works out to about 28.1 amps of draw at 12 volts, meaning you would need 674.4 amp-hours of battery storage to run it for 24 hours, or about 6-8 large deep-cycle batteries. Given the price of batteries of that size, you might be better off looking at a generator in the 1kW area, since they are pretty cheap.

Seems like it may be a bit low for the oveall power requirements since the motor appears to be a 1/5 HP drawing 7.2 amps at standard AC voltage under maximum load. So I calculate you need to have a capacity of 115v x 7.2a = 828 Watts to operate the unit at startup. The power requirements may go down to the 8.11kw per day once the interior has reached a static temp.
Here's the spec sheet for those that are interested:

Aside from setting up a portable wind turbine, you're not likely to be able to bring enough batteries to power that machine for long.
A generator is unfortunately likely to be your best bet.
