Name: Solar Water Pump 40M Deep Well Solar Power Submersible Pump Steel Machine 24V Model: SKU796617 Specifications: Material: Stainless Steel Color: Silver Power: 500W Voltage: 24V MPPT Voltage: 18V - 45V Open Circuit Voltage: 44V Working Voltage: 35V Max Flow Rate: 3m?/H Rated Flow Rate: 2m?/H H-Max: 50m Rated Lift: 35m Suitable Work Lift: 0-35m Protection Level: IP68 Working Principle: Screw Pump Electric Motor: Permanent Magnet Brushless DC Motor Water Inlet: 89mm / 3.50''(appr.) Water Outlet: 32mm / 1.26''(appr.) Pump Diameter: 89mm / 3.50''(appr.) Pump Length: 54cm / 21.26''(appr.) Wiring Length: 1m / 39.37''(appr.) Features BrandNewandhighquality. * High precision, corrosion resistance, long service life. * Built-in MPPT controller to make full use of solar energy. * Wide working voltage: 18v-45v, the best working voltage is about 36v. * The water pump can connect directly to the solar panel in the sunlight without connecting the battery. * Suitable for hand mining, agriculture, construction, aquaculture and high-rise water supply and more. Overvoltage Protection / Undervoltage Protection: The pump automatically stops working when the voltage is too high or too low; Then every 10 minutes, when the voltage is restored to 18v-45v, the pump starts automatically and starts again. Attention: * Do not use the pump over max lift. * Pumps must be submerged in water. * The water pump cannot work long without water. * The positive and negative lead of the water pump should be connected correctly. * Cable requirements: when the length of cable is greater than 30 meters, it is recommended to use 6 square or 10 square pure copper cables. * Water requirement: please do not select diameter of less than 25 mm pipe connecting pumps, pipe blockage is forbidden, bending, such as forced reduce pipe outlet diameter, otherwise it will cause the pump working current too high, motor damage.
