Difful Solar Surface Booster Water Pump Brushless with Controller 750W/1HP 1500W/2HP 2200W/3HP

The direct current generated by the solar panels runs the pumps directly, eliminating the need for expensive batteries, grid connections or generators. Large flow, often used to pump water from rivers and lakes for irrigation.

Advantages of Difful Surface Solar Pump

• Permanent magnet DC brushless synchronous motor: the efficiency is increased by 15%-20%; Save energy; Reduce the consumption of solar panels.
• The whole 304 stainless steel rotor shaft avoids the risk of broken shaft.
• Copper impeller.
• Japanese brand NSK bearing: longer working life and high reliability.
• Alloy mechanical seal: longer working life and high reliability.
• Enameled wire adopts 180°C high temperature resistant copper wire, insulation class F.
• Cold-rolled 600 silicon steel sheet stator and rotor.
• The magnet is made of 40SH aluminum iron boron material, and the temperature resistance can reach 150 ℃.
• Intelligent water shortage protection: When there is no water in the well, the program will automatically stop and start automatically after 30 minutes.

Advantages of The Difful 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.
