I was thinking during the after dinner walk:
maybe you could use something that did mppt on a solar array, put that power into
a large capacitor or small SLA bank, then a 3 phase inverter to drive the pump.
Only run the pump when enough solar power is present.
I need a tame 3 phase fractional HP induction motor.
Ebay? gumtree? There are two available at work but we reopen there
on 12 Jan and I can't wait that long.
