So i am doing an upgrade to my cabin in terms of solar/inverter/batteries etc
Currently, my deep well pump runs off my generator which is a PIA
Ideally I would like to run this off a new inverter
Currently looking at the EG4 6000XP, split phase 120/240V inverter (seems to get pretty good reviews across the board)
My pump is;
Goulds 10HS05422C 4" Submersible Water Well Pump, 10 GPM, 1/2 HP, 230 V, 2 Wire
I am not going to be at the cabin now for several months, so cant confirm the Surge rating of the pump
Pump specs are shown
Can you confirm from this info if the 6000XP would be able to cope or do i need the Surge rating?
Thanks

Quoting: zorro do i need the Surge rating?
I have a question for you. Do you have an official surge rating from the mfg or are you going to take reading with a meter of some kind? If you are metering, my understanding is that most meters cannot react fast enough with accuracy to measure a surge reading for something like a well pump. AFAIK, there are surge meters that have a special inrush, or surge setting, but they are not run-of-the-mill meters.
It would seem that inverter should have enough capacity to start and run a 240 VAC pump, but that is an assumption from specs.

I cant seem to find a surge rating anywhere?
From what I can understand, this unit here will provide that info, but I wont be able to get to the cabin now for 4+ months unfortunately
I have seen a few Youtube videos of guys using it to identify this exact issue

According to Pumpproducts the LRA on that motor is 16A.
LRA is the maximum amount of current the pump will draw when the rotor is "stalled" (from a dead stop). So 16A at 230V is 3680W.

Thanks for the info
So 3680w may be an issue
The inverter is 6000w but that is split across 2 x MPPT’s
However, it does have a max surge of 11000w for 5 seconds………..which may be enough?
So maybe I need to speak to the inverter company to see what they say as I am not too clear on that point
Thanks again - appreciated

Head pressure really matters too. You may need the static water level spec of your well when calling them.
Are there other inverters you looked at? I though most of the better ones had a surge 2x the rating for at least 30sec?
When I do my battery/inverter upgrade il be going from a 12v/1200w inverter to a 48v/3kw. I'm going to be useing a victron multiplus 2. You can parallel two to make 240v. I dont currently have a well so want to leave room in my system for one.
