Tayfun from TurkeyVeikong 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! -
Cristian from ChileIt’s very good! LCD options make it much easier to use. That’s the strong point, easy of use. And robust. Great PC software.

Brahim assad from SyriaVEIKONG 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
380V 11KW 15KW 18.5KW Variable Frequency Inverters For AC Motor
1. Deceleration over excitation function
Accurate thermal simulation platform software ensures the reliability of thermal simulation.
Each VFD500 inverter has undergone thermal simulation testing, and only the physical prototype is developed within the scope of the thermal simulation safety design requirements. After the actual test, the thermal simulation results are very close to the physical test results. In the limit test state, the thermal simulation can replace the actual load simulation and an additional layer of scientific thermal test.
2. Powerful Torque Characteristics
Powerful torque at 0 Hz, without sensors or feedback devices. Until recently, sensorless control has been out of reach for synchronous motors.
VFD500 series provides powerful starting torque algorithm without relying on pole sensors or motor feedback.
High-performance current vector control achieves powerful starting torque with an induction motor.

3. Common question when using VFD500 series
1. What issues should be paid attention to when selecting inverters for equipment?
When choosing a frequency converter, the following aspects are mainly considered:
1. Whether the inverter has been used in the equipment before, whether it is often fault protection during the previous use, if there are frequent over current and overload faults,
In the follow-up selection, it is necessary to choose a larger power inverter
2. The voltage, current, power, speed of the motor, equipment reduction ratio, control requirements and other issues must be matched;
3. Load characteristics: Whether the equipment is an impact type load or a lifting type load, when selecting an inverter for these two types of loads, it is necessary to choose a larger level power inverter
4. When installing on-site, choose the wire way of inverter input, high ambient temperature, and high altitude to choose a higher level power inverter, whether install the cabinets, install transformers for incoming and outgoing lines, etc.
