I have this same situation with my off grid well, I have a grundfos sqf5-2
and the yield wound up being .25 gpm. Originally I ran it on 2- Astronergy
235 and made a timing system using a sprinkler timer and a midnite kid
controller it was tough to control the production as the power varied and
was limited to daylight hours. I ran ac power to the control box and now
use a simple AC wall (pump draw is 400 watts) timer that up to seven daily
cycles and control the pump times calculated on the recapture rate of the
well which varies with the water table. I also use inline water gauges to
help determine the amount of water I can pump per cycle because the amount
drops so much in the summer. I went with the controlled time method over
restriction as it was going to have to be extreme in my situation, there is
a product out there I read about the dole valve that can regulate the
production to 1GPM http://www.pumpsandwells.com/mm5/PDFs/Dole%20Valves.pdf
without messing with the power directly.
