Hey Amos.
It could be a multitude of things depending on what type of
pump motor it uses. Even if you get it fixed it’s still got 10yr parts in it
elsewhere that will have to probably be replaced soon too. Have you looked into
the Grundfos SQF series? They are really nice, run off AC or DC but are kind of
limited to their flow rate at the range I think the best you could get would be
12 gpm. That way he could run the pump during the day off solar direct and then
switch it over to AC for evening pumping and cut down usage on his house system.

Subject: [RE-wrenches] Fwd: Well Pump Sizing
I have an off-grid customer who is having problems with his 10 year+ old 1/2hp
well pump. It is running and running at 900watts constant and hardly building
pressure and even caused the 250amp breaker on his single VFX3524 inverter to
trip. He is running the pump at 240V off a x240 transformer and thinking he
might need to replace the pump and might want to go with a larger 3/4hp pump
for better performance and more future capacity. Does anyone have experience
running 3/4hp pumps on this setup? The pump is approx. 200’ down in the well.
