Dear Mac,
For a non-battery, PV-direct system, you will need to shop for an appropriate
AC pump, and an AC pump controller, AKA "pump inverter". 3-phase is ideal for
this because it's better for this variable-speed application. However, this
power level, you probably will have to settle for 1-ph. There is only one
controller I know that can handle 1-ph motors. But there are some limitations,
so I suggest that you call the company:

Ask for Nikola. He is very familiar with applications like this, and very
helpful (and funny).
Yours!
Windy
