I've got a deep well pump variable frequency drive/inverter that can accept DC solar or AC inputs. It's powering a 1.5 hp three phase pump/motor that takes 200V at 6.8A (58 Hz).
(this is the inverter): https://solarsovereign.com/products/growatt-2-2kw-3hp-solar-pump-inverter-l-water-pump-inverter-grid-assisted-spi-2200tl2-hv
It's operating via solar as expected, but I need to run it from my generator sometimes (cloudy days etc.). The inverter has European style AC input (three wires -- line, neutral, ground). I have a Nema 14-30 cord coming out of the generator (10000W). I cut of the end and capped off the neutral (white) wire. Red is going to line, black to neutral, ground to ground.
The AC output is not what I'm expecting. The frequency ramps up to 50 Hz and stops. Output voltage stops at 155V, amperage at 4.2A. Pump doesn't start obviously.
What am I missing here? It this European "appliance" getting confused by the AC input wiring?
