Product Description

Description : 
Introducing the 4ESS MPPT Control NSK Bearing Solar DC Deep Well Water Pump, a revolutionary solution for efficient water extraction from deep wells using renewable solar energy. This advanced pump is designed to deliver maximum performance with minimal environmental impact, making it an ideal choice for off-grid and eco-friendly applications.

ADVANTAGE OF DC SOLAR PUMP : 
1.Permanent magnet DC brushless synchronous motor : The efficiency is increased by 15%- 20%, saving energy consumption.
2.The whole 304 stainless steel rotor shaft avoids the risk of shaft breakage.
3.Stainless steel outlet/connector/oil cylinder, with better corrosion resistance.
4.Japanese NSK bearing,longer working life.
5.Double bearing structure at the bottom of rotor, using angular contact bearing, can withstand greater axial pressure.
6.Silicon carbide-impregnated graphite mechanical seal, long service life and reliable operation.
7.180°C high temperature resistant copper wire, insulation class F.
8.Cold rolled 600 silicon steel sheet stator and rotor.
9.The magnet is made of 40SH aluminum iron boron, with a temperature resistance of 150°C.
10.304 S/S pump shaft.
11.DC Controller :
(1)Waterproof grade : IP65
(2)Wide open circuit voltage range
(3)Ambient temperature : -15°C-60°C
(4)MPPT function, the solar power utilization rate is higher.
(5)LED displays the power, voltage, current, speed etc working condition.
(6)lt can automatically adjust the speed for operation according to the sunlight power, and can also manually adjust the speed for operation according to the actual demand.
(7)Automatic startup and shutdown, without personnel on duty.
(8)Soft start : No impulse current, protect the pump motor.
(9)Over-voltage/undervoltage/over-current/phase loss/short circuit/water shortage/high-temperature protection etc
12.2 years warranty.
