Couldn't start a 1/2HP well pump of 115V/10.8A (Max)/8.3A (running). Using 400aH batteries and 2/0 AWG cable. Overloads instantly when pump starts.

You could get a soft start or variable frequency drive to fix this. We've used them in industry for over 30 years just for this situation. A 1/2to 1 hp drive can probably be gotten for $100 on ebay.

Same problem. Well man told me to buy a Grundfos low start load pump. Haven't tried it but pretty sure the startup load is too high which the Grundfos may solve.

I would recommend at least 4 BIG batteries all directly wired to the inverter. Also the "start" load seems a bit light (10.8A), that's a capacitor start motor, and I bet it's drawing close to 2000 watts, and if there is a weak link in using an inverter, it's that batteries are not good at providing a Lot of power for an instant. I had a similar issue, and after re-wiring my battery bank to supply 4 wires to the inverter, the problem was resolved. (I have a bank of 10 Very large deep cycle batteries) The inverter will shut down, if the voltage drops below 10.5 Volts. So another thing I would do is only try this, when the batteries are fully charged. (12.8 volts or higher) Good luck. I would recommend at least 4 BIG batteries all directly wired to the inverter.

I did the same thing. Charged the battery reading 13v but the pump has a red light and then a green light but it never goes on. I thought this pump would work great but it has given me a lot of problems.

I've read that you need an pump of at least 1hp or 1-1/2hp. My mine is a 1hp and it's working.

Yes. I ran my 3/4hp well pump and other high-draw tools without a problem. This generator is fantastic- starts every time and runs like a champ.

That depends on what voltage the pump is running at. It could handle 40 amp at 110, but it would require pulling 110 off each leg of the 220. If it draws 40 at 220 it will pop the breaker all the time on start up. You've got a pretty big pump if the latter is the case and you should probably go to a diesel genset.

From what I have read about this subject is that you should use a deep cycle acid battery as suggested for the watchdog BW 4000. Other batteries are probably not compatible with the "electronics" of the pump

Being a 1hp pump, the current draw is 6.5 amps. Make sure wiring should handle it. I would advise using a GFI outlet on it for shock protection should the motor windings short out (very rarely happens). That's the Engineer in me worrying about things. Good luck!

Most well pumps are 240 volt. You stated "deep water" which would indicated a need for a higher hp pump. Usually any pump over 1/3hp will be a 240v pump. These generators are 120v only!

Since I forgot what the voltage was on my pump, I hooked it up to a variable transformer and it ran on a variety of voltages, including 6v and 12v. Of course, it ran faster at 12 volts...

I have the Hayward Super Pump. Not sure of the HP it was dark when I got home tonight. I'll check it and let your know.
2207847
It should but I would find out the starting surge wattage of your pump first. I know a 1.5HP starting needs about 6000+ starting wattage which is too much for this as it's only a 4400 starting and 3400 running. However, if yours is only a 1/2HP, you might be okay. Check it out first.

I am not an electrician but a 1600 watt inverter will power an 800 watt item, how fast it will drain your batteries I have no idea. What may be of concern is your startup watts for the pump. Some name plates on pumps will give you the starting amps. I believe the formula is Watts = Amps Times volts. So if your startup watts for the pump are more than the startup watts of the inverter you may have a problem. I think this inverter was rated 2000 or 2500 startup watts. That's the best my limited knowledge can give you.

Not too sure, I imagine that if you had a separate way of switching the pump to low/high the timer would run it at either voltage.

My suggestion is to fill the pump pit with water, and see if it kicks on and off. Run a hose to the well and see it go thru the cycle about 3 times.

I returned this product because it did not meet my needs. As I recall it ran on regular 120V and didn't overheat. It just didn't inflate my pool toys for whatever reason.

About 1.8-2.2 amps @ 12V 600 gph pump. The bigger questions is for how long? Mine lasted a whopping 30 days before burning out. I would recommend a Rule or Attwood pump instead. I have some 17 year old 2000gph Rules that work just peachy and I use an Attwood Auto 800 in my shower sump which gets used almost daily. The Attwood can be cleaned easier in hair/fouling applications.

I just tried 2 18350s witch were both about 4v so that would bump it up to 8v. It came on then dimmed out. Prolly has circut protect and won't allow above a certain volt or amp. Not sure witch but I would have to say it probably won't run on CR123a.
