    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.

Trial run(How to start solar pump inverter)
Make sure all cables connections of solar panel and pump motor correct and no
need to set any parameter, if you want to set parameter, you can do as follows.
Step 1: (Keypad control):Set motor parameter P11.02- P11.06 as per motor pump name
plate If dry run protection is required, measure the unload protection current(see details in
user manual chapter for dry run function) If dry run protection not required then miss this step
and go to step 2.
Step 2: Set other related special solar pump parameters for optimization if needed.
Step 3: After trial run finishing, if motor pump still not output water when inverter is running
more than 40 Hz. Please disconnect the power supply and replace any two-phase wiring of
the motor
PMSM pump
Synchronous motor must be self-learning of motor parameters, otherwise there will be a risk
of flying,
P11.00=1 set to synchronous motor(special software)
P11.02=motor nameplate power
P11.03=Motor nameplate voltage
P11.04=Motor nameplate current
P11.05=motor nameplate frequency
P11.06=Motor nameplate speed
P11.22=Back EMF on the motor nameplate
If there is no such parameter on the nameplate, you can try to set 300V 350V for self
learning (try self-learning for 380v level)
The difference between the back-EMF setting value and the actual value should be less
than 20%, otherwise the self-learning will be abnormal
After the parameter setting is completed, set P11.10=2, press RUN then the keyboard
appears Tune for self-learning.
