Excellent performance pumping rainwater to irrigate 100 square metres of vegetable beds using solar power, delivering better than expected flow rate at low power consumption (8 amps, 12 volts, 12 L/min) with good pressure switching. However it's important to match the pressure/flow characteristics of the pump and delivery system to avoid on/off cycling.
