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 200 ~ 350V, DC 350~750V), 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.

solar pump inverter wiring application

Tips: Angle of inclination of solar panel
The solar panels need to absorb sunlight at the best angle, so that they can really play the role of improving the photoelectric conversion efficiency. Under different seasons, geographical locations and sunshine conditions, the optimal angleof inclination of solar panel will also have great changes, so the angleof inclination of the solar panels should be actively adjusted according to changes in seasons, latitude and longitude and sunshine hours. The fixed inclination angle should be chosen as the angle of inclination based on the maximum power generation in the whole year.
