Solar Pump drives are meant to drive water pumps : water pumps are particularly well suited for Solar aplication. Since the output of water can vary – afterall a water tank can be used as a buffer between the water requirement and the pump output, Solar VFDs can run the pump motors at different speeds depending on the Solar power availability and the pump output varies through the day. However the same VFD is proposed to be used to run other motors in a farm like Chara Cutting machines . ( Universal Pump Controllers) . These machines may have different starting torque requirements, and characteristics of the load. Amberroot provided an additional output filter to run these machines – typically driven by 3 Phase AC induction motors.
