From YouTube:
Designed and installed a 2 phase water pumping solution that pumps 1500 gallons a day with solar direct, no batteries, to fill a cistern and then gravity feed 3 stock tanks. Then one 12v battery is used to supply 4.5 gallons/minute at 55 psi to the home using the cistern as it’s source. The battery is maintained by a 135 watt solar module and charge controller.
