Alright. A simple switch will do the trick. Thanks again. Will post a closing note when get the pump installed.

Well crapola. I couldn't find a 115vac SQ series pump on their website. Thanks for the info on this one. Outback Power did get back to me: "Looking at the specs of this water pump (the Grundfos 5S05-13 4-inch 3-wire), it should work with the inverter you currently have. The only thing I worry...

I may be looking at the wrong material (SQ Pump Lit), but from what I can tell, the SQ and SQE pumps require 200-240 V - 10 %/+ 6 %, 50/60 Hz. My existing inverter only makes 115vac. I'm hoping for a solution that doesn't require a step-up transformer or another inverter. If you know of a...

Thanks Mr. VA Well Driller. Good to hear your positive experience with the Grundfos 3-inch pumps. The short answer to your question is yes. I checked power to the submersible cable leads at the CU200 on both solar PV power (77vdc) and house power (115vac). I pulled the pump, cut the cable at...

Thank you very much Cary for the great info. You're a national treasure, or at least a forum one. I'll verify with Outback that the inverter, PV panels, and battery bank will support that Grundfos pump. If I understand the Grundfos literature, the associated pump MS 402 will draw 42.5A AC at...

Ah, thanks Reach. I was fixated on the two-wire solution to keep from having to change out the existing cable, but drawing less power especially at start up, should be a prime consideration.

Greetings Forum! My Grundfos Model 3 SQF-2 pump (part of their SQFlex system with CU200 controller and provided PV panels) has failed and am considering replacing the pump with a 115vac single phase pump of 1/2 HP or less. I pulled the pump, know that the cable is good, and that the pump...
