70m Head 1.5m3/h Flow DC Solar Pump With Controller For Irrigation More Protection
Solar pumping system serves to provide water in remote applications where electrical grid power is either unreliable or unavailable. BLDC solar pump controller can direct use the DC power from PV array, and drive the brushless DC pumps. In sunny days, the pumping system can continuously pump water. There is no need of batteries of other energy storage devices. It is recommended to pump water to a reservoir for storage.
A float switch can be installed in the water tower to control the pump operation. And install a low-level probe in well to detect the well water so that pump will stop when there is no water.
Protection features
Electronic monitoring gives the controller the capability to monitor the system and automatically shut down in the event of:
1. Dry well conditions-- with low level switch
2. Bound pump-- with auto-reversing torque
3. High voltage surge
4. Low input voltage
5. Open motor circuit
6. Short circuit
7. Over heat
This controller provides motor overload protection by preventing motor current from exceeding rating current and by limiting the duty cycle in the event of low water level. This controller does not provide over temperature sensing of the motor.
