We drilled a well on a hill top, and had to go down 500ft to
get 3-5gpm. The static level is about 100ft. below the
The PV system is 3Kw, but there is only one inverter (no 240
A DC deep submersible pump runs about $1500. A 1/2 HP
Gould (for example) will cost a few hundred dollars and run on 110V - BUT the
system will still require a large holding tank and a 1/4 or 1/2HP DC pump (??)
to pressurize the house.
OR, I can use a 3/4 to 1 HP Gould pump with a step-up
transformer (to produce 230volt) and a BIG storage tank (should I have a
concern about the load on the inverter??).
What is the BEST way to handle this?
