I am puzzled about a solar system that I installed to run a 400’ water well for my duck impoundment. It will start easily and run for about 1 hour and then shut off. The error code reads “low battery.”
It is a 48 volt system using four VMAX tank SLR125 AGM 12V batteries in series (each is 125 mAh). There are 6 solar panels set up as two series of three panels, each series generating 135 volts. They run through a Midnight Solar charge controller.
The pump is 2 hp; I understand it should consume about 13.5 amps to run. Information on the Internet indicates a 2 hp pump takes 7500W to start and 3750W to run.
I calculate that the system should be generating about 5000 watts.
Am I missing something?
