The system consists of a solar array, a permanent magnet pump and a permanent magnet solar pumping inverter. This system is based on the design philosophy that it is easier to store water than electricity. The pump, driven by a brushless DC motor, can draw water from deep wells, rivers or lakes to fill storage tanks or reservoirs, or can be directly connected to an irrigation system.
 
There is a 24 month warranty with this solar pump.
