Interesting the variation in experiences. Most of my jobs are off-grid
these days which almost always means a (reliable) well pump need. I'd
entertain the idea of 3-phase with VFD but that's quite a bit more
initial expense for this customer and possible higher long term costs
with the VFD equipment? Once again, the value of being transformer
based (unlike the Sol-Ark) for surge.

Hi Bill,
I have yet to have an issue with the Sol Ark 12K and water pumps. We
have numerous off-grid installations with 3/4 HP well pumps with no
issues. I tend to find that compressors and inductive motor loads like
chop saws are often an issue.
Hope this helps,
Chris

I’d look at a 3 phase pump with vfd/soft start control and
eliminate the start surge.

recommendation for the largest 240V submersible well pump the
Sol-Ark 12KW inverter can start/run. Assume 500 watt load prior
to starting the pump, static level of water in well is 75 feet,
system psi when it starts is 40.
