I have customers that have Magnum 4024 running well pumps on the far side of a transformer with no problem. It helps to put the transformer between the pressure switch and the pump, that way the transformer isn't sucking power all the time. I am not sure if any of them are 1 hp pumps, I just don't remember, but some of them were 20 years ago so I will claim senility.
I am assuming that he has enough battery bank to handle the pump? Why such a large pump, is the well extremely deep or a lot of water loads at the same time and he needs the flow? I generally install a much larger pressure tank to keep the pump from frequently cycling and all seems to go well. We are lucky in this area that we don't generally have to go real deep to get water. The SW series are still rebuild able, last fall we had to have 2 redone.

If my current fix doesn't solve the problem, I have suggested having the unit fixed, which I think still happens on these puppies. I have also suggested replacing it with either an Outback 3524 or a Magnum MS 4024. He is now running a 1 HP Submersible pump ala autoformer along with the usual array of house loads. The issue is the inverter accepting and then rejecting the generator power, which I have been watching recent comments here regarding this issue. I have not thoroughly checked out pump wiring (was apparently already done by the well/pump guy, whom is reputable), but have checked the output of the Kohler 8.5 genny and Hz and voltage appear stable with and without load. So far I've gone the route of programming in a few less amps on the "battery charging" and "AC2 IN" functions. The inverter seems to be happy with new settings, this new programming was just done a few hours ago. So this may be a more generic question for those with more experience than I: Are both the OB and Magnum inverters considered equally capable of replacing the Trace? I guess I'm thinking mainly of that pump, but are there other considerations?
