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.
