2 inch mini 24 volt 48v submersible dc solar water pump

Our pump can be connect with AC and solar together.When switch is on, solar power drive pump first and when solar is not enough,AC will supply the rest power. Automatic switch between solar and AC, so no need of manuals. Or you can choose either solar or AC

Advantages and features

1.Permanent magnet brushless synchronous motor: The efficiency is improved by 15%-20%; Save energy; Reduce the consumption of solar panels.

2.321 S/S motor shaft; 321 S/S pump shaft.

3.304 S/S impeller; 304 S/S oil cylinder.

4.Japanese NSK bearing.

5.Alloy mechanical seal: Longer working life and high reliability.

6.Intelligent water shortage protection: The pump stops working automatically when there is no water in the well, and automatically start working 30 minutes later.

7.Controller:
(1)MPPT function, the solar power utilization rate is higher.
(2)Automatic charging function for battery (12V/24V/48V/96V controller): Guarantee the pump normally working, meanwhile charge the battery; And when there is no sunshine, the battery can make the pump continuously working.
(3)LED displays the power, voltage, current, speed etc working condition.
(4)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.
(5)Automatically start and stop working.
(6)Water proof and leak-proof: Double seal effect
(7)Excellent thermostability: Withstand 85℃ high temperature
(8)Soft start: No impulse current, protect the pump motor
(9)High voltage/Low voltage protection, Over-current/Over-load protection, the winding won’t be burned.

8.The first 2inch brushless solar water pump manufacturer, small volume, excellent performance.

9.High synchronous motor power density, the weight and volume of the same power pump is smaller than other factory, it is easy to take.

10.3 years warranty.
