Advantages of the Water Pump

• Permanent magnet DC brushless synchronous motor: the efficiency is increased by 15%-20%, saving energy consumption and reducing the consumption of solar panels.

• The entire 304 stainless steel rotor shaft avoids the risk of shaft breakage.

• 304 stainless steel or copper outlet, connection, cylinder.

• Japanese brand NSK bearing, longer working life.

• Double bearing structure at the bottom of the rotor, using angular contact bearings, can withstand greater axial pressure.

• Silicon carbide to impregnated graphite mechanical seal: longer working life and high reliability

• The enameled wire adopts 180 ℃ high temperature resistant copper wires, and the insulation grade is F.

• Cold-rolled 600 silicon steel sheet stator and rotor.

• The magnet is made of 40SH aluminum iron boron material, with a temperature resistance of 150 ℃.

Advantages of the Pump Controller

• Waterproof grade: IP65

• Wide open circuit voltage range

• Ambient temperature: -15℃~60℃

• Maximum input current: 17A

• MPPT function, the solar power utilization rate is higher

• LED displays the power, voltage, current, speed and other working conditions

• Automatically adjust the speed according to the power of sunlight, or manually change the speed according to the actual demand

• Automatically start and stop working, no need for personnel to operate

• Soft start: no impulse current, protect the pump motor

• Protection functions such as overvoltage/undervoltage/overcurrent/phase loss/short circuit/water shortage/high temperature protection
