[RE-wrenches] Compressor motor/SW+5548

Air compressors have a high surge current and the SW5548 doesn't handle
surges that well.  I'm surprised you even got the compressor to run.  Adding
more capacitance for the startup might help.

Hello
I've got an SW+5548 that will barley start my air compressor. Once it does
run it shows 17 Amps on the inverters loads meter. During start up it reads
60+ amps. 
Do you think better capacitors would help the situation?
BTW I've never ran the compressor off grid prior. 
I even tried #8 from the Breaker to the pressure switch, about 9ft, with no
benefit. The compressor will only start with the tank completely empty.
