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.

It adopts DSP as the core control unit to realize high - speed high - performance control.
◆ Speed control: no PG vector control, PG vector control, V/F control.
◆ The low frequency 0.25Hz and 180% torque output are realized under the non - inductive vector.
◆ The simple PLC function can achieve up to 16 speed control.
◆ The multi-lingual humanized display menu, highlight OLED and display 3 sets of state parameters.
◆ The "one key flying shuttle" keyboard can fly freely.
◆ Optimized air duct design and advanced thermal management technology.
◆ The design of reliable insulation structure ensures the safety of the inverter.
◆ The fully isolated RS485 communication module can be selected to communicate with the upper computer.
◆ We will strengthen the coating and adapt to all kinds of harsh environment.
◆ Relying on EMC design standard and unique software algorithm, the inverter can minimize the pollution of power supply.
