Well pumps and SWs revisited [RE-wrenches]

[Ezra Auerbach, DragonSun Consulting]

I recently installed a SQ 1/2 hp two wire and it starts flawlessly on
the VFX inverter I am currently running. Really does not have any surge
to speak of starts at low current and ramps up.  Lovely thing.

Hi Ken,

If you are looking for a pump answer then go with a Grundfos SQ pump.
They come in 240 and have no surge, therefor they work great especailly
with those 5548's.
