DC solar water pump adopts high- efficiency permanent magnet brushless motor, which is directly powered by solar photovoltaic array. The controller performs sine wave start commutation, automatically adjusts the output voltage and current of photovoltaic components to achieve the highest operating efficiency of the pump, and adopts automatic control technology. , The voltage is higher or lower than the normal operation requirements of the pump, that is, the circuit is cut off to protect the safety of the pump, thereby extending the service life of the pump and the controller.
1.Under-voltage protection: to protect the battery, the ordinary controller directly uses the battery power. When the battery low voltage is still consuming the battery power, the service life of the battery is greatly reduced. During the use of the controller, the battery capacity will be lower than the rated value. Control the pump to stop running and protect the battery.
2.Overvoltage protection: If the working voltage is exceeded, the controller cuts off the power supply and stops working.
3.Water shortage protection: The controller detects the water shortages for 3 minutes and then controls the water pump to stop working to protect the water pump.
4.Automatic overload protection: The controller will automatically stop working after 2 minutes of overload
5.Automatic card machine protection: The controller will run in reverse when it encounters a card machine, and the card machine will be cancelled and restarted.
6.Automatic high temperature protection: The controller automatically recognizes abnormal high temperature and automatically protects
