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 (optional).
  • Protect itself in trouble and improve the reliability of whole system.

solar pump inverter wiring application

Tips: Advantages of solar pump inverter
1. Water storage instead of electricity storage, no battery device, direct drive water pumping, high reliability of the device, and greatly reduce construction and maintenance costs.
2. The output voltage is optimized by sinusoidal PWM control.
3. Multiple operating modes and MPPT control modes are available.
4. The speed adjustment range of the pump can be set freely according to the actual system conditions.
5. Optional upper and lower water level detection and control circuit.
