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: Polycrystalline silicon solar panel vs. monocrystalline silicon solar panel
Photoelectric conversion efficiency:
The conversion efficiency of monocrystalline silicon is 17%-25%, and the conversion efficiency of polycrystalline silicon is about 16%, but the price of monocrystalline silicon is higher than polycrystalline silicon.
The difference between monocrystalline silicon and polycrystalline silicon:
The surface of the monocrystalline silicon is black, and the surface of the polycrystalline silicon is blue or colored.
monocrystalline silicon receives light in one direction, and polysilicon receives light in multiple directions.
At the same power capacity, the area of the polysilicon plate is 1.1 times larger than that of the single crystal silicon.
