High Head, High Flow Pump Solutions – We are now proud to offer SunPumps drives that can run any three-phase, 380vac or 230vac motor directly from a solar array. These drives will operate pumps up to 75 horsepower anytime there is sufficient sunshine. With today’s solar module pricing, solar water pumping has become very affordable. These pumps are made in Arizona by SunPumps, one of the world’s best solar pumping companies. For a rough calculation of the necessary solar array, assume 1.2kW per motor horsepower or less.
