    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!

    It’s very good! LCD options make it much easier to use. That’s the strong point, easy of use. And robust. Great PC software.

    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.

1.Brief introduction of Veikong in China


Shenzhen Veikong Electric CO.,Ltd. is a professional VFD manufacturer in China for more than 20 years. We have strong R&D groups and excellent technicians for better technical support and software upgrading. Besides, we can provide you 18 months warranty, once there is anything wrong during this period, we will solve it as soon as possible. Further more, we support OEM service like what we do for your usual clients, we can provide you not only the OEM logo, but also some different parameter language or special function like our textile frequency is the special function for textile machines. 

If you want to develop your market and gain more benefit, cooperate with us and get all of it!



2.We have rigorous and complete production flow and testing devices to make sure the quality.


As we know that the process control is very important during the process of manufacturing, and then I will share with you some info abt this.
