Good day @Modina
I have a client that I have connected a 1.5kw 3phase river pump, going through a 3 phase rectifier, I am getting a fluctuating voltage between 310V and 330V. I have connected the pump to a Growatt axpert 5kw inverter with a high voltage mppt. The inverter sees the power coming in, but only takes about a 100w from the motor. Is there anything I might have missed?
