    Can I use 1 phase from a 3 phase inverter to drive a single phase pump?

    I have an array with a DC to AC 3 phase inverter (no batteries) driving a well pump. This is only used a couple times a week.

    I want to use it to drive two single phase pumps, one is 1.1kw, the other is .35kw.

    The 3 phase motor is 4kw.

    I will not be running the 3 phase and single phase at the same time.


    Is it ok to draw on a single phase out of the controller to power the single phase pumps?

      I have no idea how that would work. Split phase inverters like my XW6048, only allow so much load imbalance on each phase. See if you can find a Imbalance spec for your inverter
