If you have 240 VAC look at the Pentair wild AC pumps I have one at 20 GPM and
am a believer. Tapers on - soft start, varies the volts & amperage with flow
and tapers the amperage down as it reaches a full expansion tank.
Even better my local well pump installer sells & services it so I do not have
to! Getting a little smarter as I get older.

Subject: [RE-wrenches] Pump power
Wrenchers,
We're upgrading an off-grid water system. Dynamic head while
pumping at 20 GPM is 150 ft from water level to wellhead and then its 85 ft
vertical to storage tank so 235 ft total head to open discharge. We would like
to get most of that 20 GPM, we need to know if there is personal experience
with starting a 1.5 or 2 HP, 240 vac, 2 wire submersible pump against that kind
of head with an Outback Flex
Power2 (2 X VFXR3648A-01 inverters).
The FP2 will also be powering standard off-grid loads. There is
plenty of battery behind the inverters. If a soft-start solution is required,
some specifics would be great. Grundfos doesn't seem to have an option for
these requirements, solar-direct is not an option at this location.
Thanks,
Bill
