  • 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: Why are there fewer solar pump inverter failures in low temperature weather?
1. Winter light is usually not good, solar pump inverter output power is low, solar VFD is running at low load, so the possibility of failure is low.
2. The ambient temperature is low, solar pump inverter operates at low temperature, the reliability of electronic components increases, so it is not easy to malfunction.
Low temperature will not affect the operation of the solar pump inverter. Most components can withstand low temperatures of -25 °C. Moreover, once the inverter is running, when the power component has a current, the temperature will rise and the operating temperature will be greater than the ambient temperature.
Most of the solar pump inverter faults are due to heat, so the inverter should be installed in the place where ventilation and heat dissipation. If you want to have a long life of the inverter, try to choose a inverter with higher power.
