On or off Grid AC/DC submersible well pumps

Check it out! these are new and very cool! My friend has one pumping from 550 feet on just 6 -85 watt Solar Panels. Submersible Solar pumps were never able to pump from that deep until now.

Grundfos company is now producing one that will pay for it's self and the panels in about 3 years or less. Panels and Etc. can be purchased cheaper elsewhere on the net so I am going to stick to the pump.

The pump runs on 30V-300V DC or 90-240V AC though the same wires! This is very cool! The computer on the surface communicates with the electronics in the pump also through these very same wires.

The unit is hooked to both AC and your DC panels (Wired in series) at the surface and is all automatic and can be set for however you want it to run, DC primary or AC primary, Or switched when needed.

I am going to install one on my well very soon. I am going to of course make it Solar primary so that I can save on my grid bill. If you have a well this is definitely worth checking out! Download the 2009 Brochure for all the details!

Has anyone seen Simple Pump?

I was checking out a product from Simplepump.com. They make a motor adapter with a solar panel and the product runs around $1,700.00 or so. I think they can pump under pressure up to 330-350 feet.

Something like that is nice if you have a shallow well. Ours sits at 180 feet for the pump and our static level is around 130-140 I believe. I think if I did that I would have it pump to a tank and then use a small booster pump to go for pressure.

My 2 cents.

Thank you for the timely information

We recently acquired a house and land that borders our "farm". One of the great things about this place is that it already has a good well, and the previous owner had run water lines over to our side of the road. Each of our homes has one water faucet that comes from the well. The bad part is that it is running off electric from the newly acquired home. I want each house to have it's own faucet for garden and animal watering, and of course in emergencies where we might lose our rural water. But I don't want the occupiers of the new house to foot the bill of course. I had been wondering about doing it this way, or with 12 volt batteries hooked up to a charger. Thank you for the information.

This has been a long time coming Dale

Out here in the desert this has been a long time coming. All the wells are pretty deep here. A life long friend and rancher has been pumping for his stock with solar for awhile now.

But not with a submersible, he has a jack pump sitting on top of a traditional sucker rod system like the old windmills have. He runs the jack pump with a 1.5 HP 24 volt motor powered by solar panels.

The only issue with this set up is that the "leathers" down in the pump wear out and the well has to be pulled quite often to replace them. So a submersible like this one is the cure because it would last for years and years without having to be pulled.

Good luck and glad I could help Sir!

If I disappear from a discussion please forgive me. My 24-7 business requires me to split mid-sentence to serve them. I am not ducking out, I will be back later to catch up.

Products with engineering specs.

Where did you find this Paul?

Lol, I looked for more details but could not find them my friend. Seriously, my friend Danny is pulling from 550 feet with one. I will have to get the model number from him to compare.

I have to ask? did my contact offend you Paul? Or did you not get it? I really need to know man because it has been bothering me.

I googled.

My current pump is 3/4 HP in a 103 ft well. I get 9gpm with 110VAC. I went looking to do some comparing.

I've been under the weather. I got behind, I have 4 emails and a snail mail package to send, someday soon.

I find forum responses easy, but personal responses are usually considered and hopefully thoughtful.

No worries my friend. I don't recall that you ever offended me. And I never intended to offend you.
