    Have heard that before, but these were the measurements I took a couple years ago when the system ran off-grid. Just coincidence perhaps?

    P.S. Running the capacitive load of the lights on the same circuit as the inductive load of the pumps pulled the PF up closer to one just as you would expect. Lights & pumps were more efficient that just running pumps or just running the lights.

      I am confused now.
      Is this calculation in bold for a 24 volt system?

      Please clarify, thank you.

        If you are refer to Mapmaker's corrected figure in BOLD, Yes it is base on 24 volts. I think is over kill for a 157watts load. I would just get 1500 watts Panels and 500 amps hour batteries at 24 volts system and a backup Generator for cloudy/rainy days.
