    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.

Drive design & features

 

1. Even more compact

 

VEIKONG continues to make applications even smaller by combining the compact designed drive with the light, efficient design of a synchronous motor.

 

Use Side-by-Side installation for an even more compact setup.

 

Finless models available

 

2. Independent duct design

 

Independent air duct design, effectively preventing dust entering inverter, causing short-circuit and other faults and improving reliability

 

Use bigger air volume and long life cooling fan effectively reduces the internal temperature rise of the inverter and ensures reliable and stable operation of inverter.

 

3. Perfect protection system

 

Designed for 10 years of maintenance-free operation.

 

Cooling fan, capacitors, relays, and IGBTs have been carefully selected and designed for a life expectancy up to ten years
