ADVANTAGE OF DC SOLAR PUMP

1.Permanent magnet DC brushless synchronous motor:The efficiency is improved by 15% -  20%;Save energy;Reduce the consumption of solar panels.
2.304 S/S pump shaft.
3.Brass or stainless steel outlet/connector/oil cylinder.
4.Japanese NSK bearing:prolong the working life.
5.LED display shows various data such as power,voltage,current,speed and error code etc.
6.Alloy mechanical seal:Longer working life and high reliability.
7.Motor coil is made by automatic  winding machine with centralized winding technology,motor efficiency is much improved.
8.Intelligent water shortage protection:The pump stops working automatically when there is no water in the well,and automatically start working 30 minutes later.
9.Controller:
(1)Waterproof grade:IP65
(2)Ambient temperature:-15ºC~60ºC
(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.
(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)Waterproof 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
10.2 years warranty.
