Features

  • Solar pump inverter adopts advanced MPPT control technology, real-time detection of solar panels power voltage, tracking the highest voltage and current, efficiency is as high as 98%.
  • It can enter automatically to sleep mode when the intensity of sunlight is weak, as well as can exit the sleep mode when the intensity of sunlight is becoming strong.
  • Automatic sleep when on high-water level and automatic restart when on low-water level to realize automatic control through water level.
  • Multiple power supply design, power input can be solar energy photovoltaic DC power supply (DC 260~350V, DC 450~750V), can also be single phase or three phase AC power, simple wiring.
  • Smart operation, water level detection and operation panel to prevent overflow, dry pumping.
  • Protect itself in trouble and improve the reliability of whole system.
  • The bypass- AC source which runs automatically when the sun is Not sufficient or absent.

solar pump inverter wiring application

Tips: Suggestions on how to build solar pump system
1. Installation of solar panels: The installation position should be no shade or obstruction all year round, and there is sufficient direct sunlight. The installation angle with the ground can be determined by reference to the local latitude to ensure that the solar panels receives the max. amount of illumination.
2. Selection of solar water pump inverter: Manufacturers with good product quality should be selected. Solar variable frequency drive with high tracking accuracy and conversion efficiency should be chosen. Tracking accuracy and conversion efficiency will directly affect the pumping effect.
3. Antifreeze: When installing in high and cold areas, the antifreeze treatment of the pipeline system should be done. It is necessary to bury the pipeline below the freezing line. In winter, the water cannot be stored in the pipeline. Otherwise, the pipeline may be broken due to icing.
