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.

solar pump inverter wiring application

Tips: The motor does not rotate after the solar pump inverter is running
Check if there is a balanced three phase output between the pump motor U, V, W.
If there is a balanced 3-phase output, the motor circuit or its own damage, or the motor is blocked due to mechanical reasons.
If there is output but the three phases are not balanced, it should be damaged by the solar pump inverter's drive board or the output module.
If there is no output voltage, the drive board or output module may be damaged.
