The usual wire I see running to most pumps is #10
UF cable. A 450 foot run might create too much
voltage drop. Maybe a buck boost transformer would help.

Hi Bob; I checked the connections for corrosion,
and the wire size looks like "the usual" for up
here in this area, it's only about 100 feet and
the usual well depth around here is 350 ft.
Running stouter wire might be an option to
consider...but that's a lot of digging. I'm just
hoping VSD might be a quick and dirty solution.

Don't know about the variable speed but are the
wires feeding the pump large enough for the distance?
Sounds like it might be voltage starved because
of a high resistance / bad connection or a long
wire run and the need for a larger wire ?
Just a thought,

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.Â
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?
Thanks;Â
