    VEIKONG VFD500 output frequency is stable when the others are fluctuating. Also output current is less than others, that’s why output frequency is higher too which can save more energy.

* 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.
