On or off Grid AC/DC submersible well pumpsSubmitted by ATruepatriot on Sun, 09/15/2013 - 15:16
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!
