Wrenches,
Has anyone powered a Grundfos SQ or SQE series soft-start AC
submersible pump from a modified square wave inverter?
I need to run a 1/2 hp 115V AC sub on a 1990-era Heart EMS 2800-12.
The customer likes his equipment so I'm not encouraging an inverter
upgrad
Hi Wrenches,
I was short one SW 275 Protect module on an install and substituted a SW
275 mono expecting that i could swap it out, but SolarWorld has not been
running those for a long time, so...
Does anyone have a SW 275 Protect module (or larger wattage) on the shelf?
Thanks,
Kris

The classic 150 with a 100 amp breaker tripping. Solution was to swap out
the charge controller and breaker. No more problems, sent them both back
to midnite and they both tested fine. New controller and breaker are
working fine. Never did find what was causing the issue just found a
solution.
All –
I’ve had some off-list responses to my post below that I wanted to share.
Specifically, I was speaking about standard grid-tied inverters when I
mentioned that their neutrals may not count as current carrying. I just
confirmed this with SMA, for example.
Off grid or stand alone inverter
In addition to what is stated below, my understanding is that neutrals in
many commonly used inverter output circuits are not current carrying
conductors either. You’ll have to check with your inverter manufacturer to
be certain, however.
Best,
