That's what I do, works fine, 3/4 hp compressor, 4 hours per day, 9
amps AC, 90 amps DC.

That seems odd - my 1/2 motor, a Leeson, is rated at 1/2 Hp, with a 39
Amp draw. It normally uses no more than 30 Amps. Scaling up, I would
expect yours to be 60 Amps or less.

I'm going through an inverter in DC mode, probably losing something
there. The compressor itself is AC only.
