    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!

    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.

* Automatic control with water level.Entering sleeping mode at high-water level and automatically restart at low-water level.
* Automatic control with sunlight.Entering sleeping mode with weak sunlight and automatically exits the sleeping mode when the sunlight is becoming stronger.

4. Protection: Over voltage,overload,over heat,dry-run motor protection.

5. Remote monitoring: RS485 communication port is available for pump controller or computer connection.

6. LCD display: Convenient to understand the working state of the frequency inverter VFD and the devices,and to set the parameters when necessary.



1. GPRS (support 2g/3g/4g internet)
It supplies water volume monitoring and operation of inverter from anywhere at anytim
It’s convenient to visit real time and historical data via web or Android APP anytime and anywhere.
This easy-to-use platform makes monitoring of solar pump systems simple and convenient,
far reducing operate time and monitoring costs as well.

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.
