[RE-wrenches] Compressor motor/SW+5548

[Dan Fink]

Does your air compressor have an unloader valve, or can you install one?
That should do the trick, sounds like you are just running into the regular
high surge current demand.
Off the grid, compressors are in about the same nasty league as old well
pumps as far as surge demand.
