  1. DC Brushless Permanent-magnetic synchronous motor for solar powered submersible dc water pump to get high speed and high efficiency.
  2. NSK bearing with alloy mechanical seal, offering the longer working life.
  3. MPPT function offers higher utilization rate of solar energy.
  4. Water proof and leak proof based on double water seal.
  5. Intelligent water shortage protection: the pump stops working automatically when there is no water in the well, and automatically starts working 30 minutes later.
  6. Featured function: MPPT function, Soft start function, Dry running protection, Adjustable speed function, Error wiring protection, Over/ under-voltage protection, Overload protection, Over-current protection, phase-loss protection, High working temperature protection.



Waterproof grade: IP65

Max. input current:15A

MPPT function, the solar power utilization rate is higher.

Automatic charging function: Guarantee the pump normally working, meanwhile charge the battery; And when there is no sunshine, the battery can make the pump continuously working.

LED displays the power, voltage, current, speed etc working condition.

Frequency conversion function: It can automatically run with frequency conversion according to the solar power and user also can change the speed of pump manually. Automatically start and stop working.

Water proof and leak-proof: Double seal effect.

Soft start: No impulse current, protect the pump motor.

High voltage/Low voltage/Over-current/High temperature protection.
