  • 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 applicationTips: How to choose inverter for PV off-grid system?

If it is only used for pumping water, and a water tower can be built, it is recommended to use a solar pump inverter, which can save costs. For example, if a 2 horsepower water pump is used with an ordinary inverter, it needs an off-grid inverter of more than 5 kW to drive it, and also a battery of more than 200 AH is required. But if you choose a solar pump inverter, only 2kW power capacity is required.
