You can't run it for long.....unless you have submarine batteries.

Not true. We run the inverter all night on 4 golf cart batteries, $55
each at Sam's Club, typical life 3 years, about 600 charge/discharge
cycles at 30 to 50% average discharge, average load 10 to 20 amps.

How long can you run a submarine on 4 golf cart batteries?
