<p>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.</p>

look at a 3 phase pump with vfd/soft start control and
eliminate the start surge. <br>

on 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.<br>
