[RE-wrenches] Well pump with Sol-Ark

[William Bryce]

For high surge and unbalanced splitphase loads, you can’t beat a Midnite
Solar Rosie Inverter.  It uses Sic FET’s and is rock solid. I have an early
unit and it’s starts my 5hp compressor and still runs other loads without a
flicker.

Runs loads that even my Schneider XW+ would not.  Why complicate the
installs with a VFD? Just install an inverter that can do what you need it
to do?
