Main Features:

●Permanent magnet DC brushless synchronous motor which is save energy and high efficiency (improved by 15%-20%), so it can also help to reduce the consumption of solar panels

●The whole pump is made by Stainless steel, including the pump casing, shaft, impeller, outlet, oil cylinder, etc.

●By using Japanese brand NSK bearing to make sure the long using life.

●By using alloy mechanical seal to make Longer working life and high reliability.

●The wire winding is made by automatic winding machine using centralized winding technology, to improve the motor efficiency.

●High-precision, strictly controlling the dimension precision and smoothness which is also very important to make a good quality pump.

● Intelligent water shortage and full water protection.

●DC Controller:

   (1) Waterproof grade: IP65.

   (2) Ambient temperature: -15℃ to 60℃.

   (3) MPPT function, the solar power utilization rate is higher.

   (4) 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.

   (5) LED displays the power, voltage, current, speed etc working condition and error code.

   (6) 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.

   (7) Automatically start and stop working.

   (8) Water proof and leak-proof: Double seal effect.

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

   (10) High voltage/Low voltage/Over-current/High temperature protection.

●2 years warranty.
