    Veikong solar pump inverter is really in very good quality and we also prepared some promotional products for exhibition. We are going to make new orders soon. Last year there was only one local agent and this year, there are more than 8. Some of them only sell Veikong!

    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.

Product Description

3 Phase MPPT 99% Solar Pump Inverter chinese manufacturer high performance

VEIKONG is solar pump inverter, industrial vfd, soft starter manufacturer. 


Product Details and 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.

Technical Questions and solutions


1. How to achieve Automatic start after stop?

If it is controlled by keyboard no need to set any parameter. If you want to control by external switch

As the default control mode is keypad control, First set P00.06=1 and use a wire or switch to connect com and DI1,When the switch is closed, the drive run, when the switch is open, the drive stop


2. How to use a float in the water tank to stop the pump if the tank is full?

If your float signal is digital signal Use float switch to short DI 1 and com and P00.06=1


3. How to design solar PV water pump system?
Key point: the rated VOC and VMP and power of the PV Array need to match the input range of the inverter. If needed, we will provide technical support online.
