Really we should say what the In-Rush current is, but like myself most people will not have a DMM that can record that information. Recently bought a meter that can, and ran all over the shop just to see what a chop saw, a metal cutting skillsaw, compressor and a welder would peak at. Some were very high in-rush loads.Folks responding with their pump situation might want to say how deep their pump is. The load is much greater starting with a few 100 feet of water column than without...

Well is 300' deep, 35' to bedrock per the online water well records I found for my house but I'm not sure where the pump is hanging.My SRNE ASF 10kw handles my 1hp deep well pump no problem, I clamped it at ~40a per leg.
Unfortunately the ASF split phase parallel version is not available yet. The SRNE HYP can be paralleled with the current version.
My TP6048 also handled the well pump.
I sure you know that the condition of the start capacitor can have a big effect on the starting current. I've replaced mine a few times over the years....and with 200A available, no issue when the inverter calls for 114A.
I went through this same issue for starting some pretty large stationary equipment, 2-5Hp induction motors. As long as the inverters could pull 200A each then starting motors was a non-issue.
I have an AIMS 12 volt 4000 watt LF inverter and 3 200ah lead acid batteries. It starts my 3/4 hp well pump without issue. But it has a 20 amp breaker so a 6000 watt with a 30 amp breaker would be better with a 1 hp. My pump is a 2 wire at 160 foot depth. It's not a solar inverter though.I am looking for a single 240v split phase solar inverter in the 6000w range that is expandable like the eg4 6000xp. The question is “will it start a 2 wire 240v 1hp motor“. Or a different unit that will work. Needs to have a very low idle current draw.
I have a 2 wire - 240vac - 1hp deep well submersible pump.
all measurements were taken from the breaker panel.
voltage 239 volts
Inrush current is 22.85 amps
max running current is 10.53 amps
normal running amps is 8.79 amps
Will, it would be nice if you could test different inverters on starting a 1 hp well pump. There are a lot of people who have wells and starting a induction load can tap out a lot of inverters. It would make a great video. Thanks for all your help!
I would hope so for the cost. Most decent sized inverter will run that well pump.My Deye (Sol Ark) runs my wellpump without any hickups ^^.
Makes me want to do another test:edit: ran some water, when the pump clicked on the In-rush was 15.6A on my 120v pump.
And 5.8A running steady a few seconds after starting.
Not high tech, but I installed a 30 amp 230 volt plug inline on mine. I just unplug it and plug in a 10 gauge extension cord either to my inverter or to my generator. It has worked good for years.This is probably a dumb question but how are you guys accessing the pump wiring? I'm building out a home battery backup plan - system.
Trying to sort out all the options, but getting water out of the ground with battery power is probably the biggest hurdle.
During Sandy we were out for a week. I was able to back feed our 6kw generator into the house panel (via detached garage panel) to power various loads and the water pump when needed. Didn't access the pump wires directly but thinking I'll need to since I am not going to deliver 240 V to the panel from batteries, for short 2–5 day outages (which is my target)
For my well pump, and a few other critical items, I installed a Reliance Critical Loads panel - I went with the 306 (30A with 6 separate breakers) - this lets me choose between utility or off grid to power the well pump (plus my furnace fan, fridge, few freezers, kitchen and bathroom lights and one kitchen plug - where She makes her tea in the mornings)This is probably a dumb question but how are you guys accessing the pump wiring?
