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.Intelligent water shortage protection: The pump stops working automatically when there is no water in the well, and automatically start working 30 minutes later.
3.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.
The first 2inch brushless solar water pump manufacturer, small volume, excellent performance.
