Esteemed Wrenches; I have a client in a very remote mountain location who is having trouble with his inverter starting his well pump when battery state of charge is below 75%. 24v system, Magnum inverter.
It's a 2-wire pump, unknown age, model, horsepower, or well depth. It has always given him trouble, that's why he upgraded to 24v, and the situation is better, but not ideal yet. I don't think adding a hard start capacitor would help as there should be one inside the pump itself, though I suppose it could be blown. Because of the distance and the rough road, it would be super expensive for a well company to come up there, pull the old pump and set a new, modern soft-start one. Has anyone here had any experience with retrofitting variable speed drive units to an unknown pump? If so, what models have you tried and what do you prefer?
