Generator run time ?

[Camerons]

Hi all. Could anyone offer some guidance on how long generator will run with just charging as the load. from looking at the onan specs it looks like burn rate of .4g/hr and 15 gal in the tank so should run for 37.5 hrs sound right ?

The tank can only be filled up to 77% full, so theoretically you might get up to 28 hours run time. In practice it will be less.

Thanks appreciate the input

Mine could run w/ the rear A/C on for about 18-20 hours depending on temperature outside.
