Maximum Power Point Tracking Solar Pump Controller With CE Certification
Solar pumping system, is constituted by solar module array, combiner box, liquid level switch,solar pump etc. It aims at providing solutions for the region that suffers water shortage, no power supply or uncertain power supply.
The NK112 solar controller is a speed-adjustable motor driver designed for any three-phase asynchronous motor in accordance with the IEC standard. The NK112 solar water pump system converts the high-voltage direct current of the solar cell array into alternating current, and drives a standard three-phase asynchronous motor to supply water in remote areas. When the solar energy is insufficient, the controller can switch to the standby single-phase or three-phase AC power supply manually, such as a generator. The controller provides fault detection, motor soft start and speed control.
The NK112 solar water pump controller has the function of plug and play, and is convenient to install. NK112 solar water pump controller high standard, high reliability products . Under weak light conditions, the controller will do its best to drive the water pump to lift the water and, if the light continues to be weak, the controller will decrease the pump speed to protect the system's components from damage and shut down only in extreme cases . When the abnormal condition disappears, the controller will re-drive the water pump to operate.
