I've read this link, but still had some questions:
Small off-grid cabin.
2800 gal. water storage container (above ground and 3 feet away from the cabin)
80 gallon (30 gallon water capacity with bladder) pre-pressurized tank
As it stands I'm using an AC flotec pump (1/2hp - 115v - 9.4A). I'm still in the construction phase (and don't have solar installed yet) so I power the AC pump with a 5k generator. This is plenty for the pump with a surge of 3300.
Eventually, I plan to use a DC pump with my system. The DC pump only has to pull water from 4 feet away into a pressure tank that is two feet away. The water is already stored above ground which should be easier on the DC pump because it doesn't have to draw from a well. I would like to have water pressure of 45-50 lbs.
Based on my specs, I was hoping for a recommendation on a DC pump with a built-in pressure switch that will fill my pressure tank to 45-50lbs and run off of a 12v battery bank (recharged by 1000k of PV). Hopefully something moderately priced. Sureflo?
Lastly, I would still like to keep the AC pump in line for emergencies. Can I have two pumps in line? Anyone else have a set up like this, with two pump types (AC & DC) in the same line?
