Our 1 hp submersible well pump runs @ 240VAC, about 8-9 amps.
Starting load is some unknown multiple of the 8A run.
When the utility fails, we run on the 21kw Perkins Diesel genset, starts the well pump fine.
(However, the new heat pump scroll compressor really zapped the genset for the start, I put a soft start kit on the compressor, fixed the startup load for the heat pump)
Now I am installing a small (7kw) solar power system, would like to know if it is possible to install a Teco Westinghouse VFD (or similar) on the well pump, so as to ramp up the starting load gradually.
Not sure if the VFD would go in front of or behind the well pump control box.
Guessing after (between the control box and the pump), so that the control box sees a normal waveform.
Or is there a better way to reduce the instantaneous overload on the solar inverter when the well pump starts? What do you think?
