4 Inch Stainless Steel AC DC Solar Power Submersible Screw Impeller Borehole Pump

/Product Description/  /Advantages/  ·Permanent magnet DC brushless synchronous motor: The efficiency is improved by 15%-20%; Save energy; Reduce the consumption of solar panels.·304 S/S pump shaft.·S/S outlet/connector/oil cylinder.·Double bearing motor base can work under more axial pressure.·Alloy mechanical seal; Longer working life and high reliability.·Motor coil is made by automatic winding machine with centralized winding technology, motor efficiency is much improved.·Intelligent water shortage protection: The pump stops working automatically when there is no water in the well, and automatically start working 30 minutes later.  ·Waterproof grade: IP65·VOC range:24V controller: 18V-50V36V controller: 30V-96V48V controller: 30V-96V72V controller: 50V-150V96V controller: 60V-180V110V controller: 60V-180V·Ambient temperature: -15°C~60°C·Max. input current: 15A·Automatically start and stop working.·Water proof and leak-proof: Double seal effect.·MPPT function, the solar power utilization rate is higher.·Soft start: No impulse current, protect the pump motor.·High voltage/Low voltage/Over-current High temperature protection·LED displays the power, voltage, current speed etc working condition·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·Automatic charging function: Guarantee the pump normaly working, meanwhile charge the battery; And when there is no sunshine, the battery can make the pump continuously working.·Spare parts free of charge/Controller Advantages/  (1) MPPT function, the highest solar utilization rate(2) The 24V/48V/72V/110V controller has an automatic charging function to ensure that the solar pump is charged while charging the battery; in the absence of sunlight, the battery can keep the solar pump working continuously.(3) Digital display of power, voltage, current, speed and other working conditions.(4) Frequency conversion function: It can automatically convert the frequency according to the sunlight power, and can also manually adjust the speed operation according the actual needs.(5) Automatic power on and off.(6) Waterproof and sealed: double sealing effect.(7) High temperature resistance: up to 85°C high temperature.(8) Soft start: no inrush current, protect the pump motor.(9) High/Low voltage protection, overcurrent/overload protection, stator coil never burns./How to choose the correct solar water pump?/  Head Calculate 1. Distance of 'B+C+D/10' if have a water tank 2. Distance of 'B' if without water tank Flow Calculate:How much water per hour or per day do you want? Selecting the solar pump model that meets your requirements against the pump model number table.   /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
