4SPG Series Solar Pump

Solar water supply system consists of solar generating systems,photovoltaic water pump controller system and pump .Solar arrays are in series-parallel of solar modules, absorbing solar radiation energy and converting it into electricity to supply power for the entire system .Photovoltaic  water pump controller regulates the running system, turning instable DC of solar array into stable DC to drive DC pump , and regulates the output current in accordance with sunlight intensty to achieve maximum power point tracking (MPPT),maximizing the use of solar energy .

Solar submersible pump ,immersed into the water ,connects motor with pump directly . It consists of submersible pump ,motor ,water pipe ,cable ,protection devices ,solar panel and etc . Solar panels convert light into electrical energy , connecting to dedicated low-voltage solar pump. It is convenient ,practical and simple.The solar pump pumps works automatically in the sun ,while itpumps continuously by power device with little sunshine. It is suitbable for irrigation, gardening ,fountains,family,pastoral grasslands , the work station, high altitude mountain in remote sunny areas without electricity supply ,and rivers, reservoirs ,canals and other water pumping projects used in mining ,farming ,agriculture ,construction and etc .

1. Permanent magnet brushless motor ,combined with controller,reaches the max efficency 85%, achieve 20-25%than the traditional AC one .

2. High-performance wear-resistant electric pump , introduced from the advanced foreign technology , is equipped with water immersion style stainless steel submersible motor of the current international advanced technology in power part ,pollution-free to water ,up to 40 meters  deep .
