Hmm, The SQF and SQ series pumps are soft start!

The Grundfos 16SQF-10 will give you 12 to 13 gpm at 230 feet. But that
is working at the upper edge of this pump's lift rating. Not sure that
meets your definition of most of the 20 gpm.
The maximum output current, 50 A, of the inverter system equals the
locked rotor amps of a 2 HP motor.
Hi Bill
I would not recommend the Sqflex as it does have that gpm/height possibility
but would recommend the Grundfos SQ.
The 22SQ15-220 will do what you want.
1.5hp, soft start, 240vac, way less expensive, uses a bit more 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
