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 99%.
* 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, 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.
