Surface Solar Water Pump for Irrigation – 500W
This DC Surface Solar Pump is designed to convert sunlight into electrical energy through solar panels, which is then transmitted to the solar pump controller. The controller stabilizes the voltage and supplies power to drive the pump’s motor. Optional backup batteries can be connected to store excess energy for use when sunlight is insufficient. A water level detector or sensor is also included to prevent the pump from running dry and automatically turn it off when a tank is full.
**Applications:**
1. Agricultural irrigation
2. Drinking and living water supply
3. Garden irrigation
4. Fountains
**Features:**
1. Improved efficiency by 25% using permanent magnet, direct current, brushless, and sensorless motor technology.
2. Double plastic packaging for rotor and stator, with motor insulation ≥300MΩ, significantly enhancing motor safety.
3. High-tech products utilizing MPPT and DSP chip technology.
4. 100% copper wire and cold-rolled silicon steel sheets.
5. Stainless steel 304 and 316 shafts, motor body, and screws.
