KE300A-01 Solar Pump Inverter Series

KE300A-01 series solar pump inverter adopts MPPT (Maximum Power Point Tracking) and excellent motor drive technology to maximize the power output from solar panels. KE300A-01 inverters are compatible with both AC and DC input, and the AC output can be used for various kinds of normal AC pumps. When the solar power is not available, or the sunshine is not strong enough to drive the pump, the inverter could be automatically switched to single-phase or three-phase AC input power, such as generator, grid power.
