Hey,
I have a friend who wants to put in a solar powered backup in case his power goes out so he can run his well. I was thinking of putting in enough batteries to start and run the thing (at 21 volts and 9.8 max amps), and am wondering what kind of set up would be most cost effective? I was thinking a few solar panels (4 panels for around 800 watts) and then just running a charge controller and a battery bank that would tie directly into the pump's electric system. I would also put in a DC disconnect and mounting brackets for all of the batteries to be at spec for NEIS, but is there anything else anyone can think of that I would need to make it work? The panels would charge the batteries as needed all day, and because the pump doesn't stay on all the time I am hoping the battery life will do for this application. Any advice would be greatly appreciated. Thanks in advance!
