    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!

    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.

P11.02 Motor rated power


Ø when power is less than 1kw ,0.75kw set to 0.8 as per round up principle ,0.55kw motor set 0.6

Ø when change motor rated power,AC drive will automatically set other parameter of motor name plate and motor model parameter be careful to use

P47.00 Solar pump Mppt function enable

0: invalid

The parameters behind the 47 group cannot be changed!

1: Enable, to enable the special mppt function of the PV pump inverter





Solar pump control mode


Units digit’s: Startup mode

0: Manual start, the start mode is determined by P00.06;

1: automatic start,

When P00.06 change, the association changes here.

P00.06=0, when inverter starts and stops by keypad control, it is automatically modified to 1-automatic start

P00.06=1, when inverter starts and stops by terminal control.it is automatically changed to 0-manual start

Ten digit’s: MPPT function

0: MPPT is disabled; CVT control is used (voltage is given as P47.04).

1: Enable MPPT.

Hundred’s unit automatic switching function

0: prohibited

1: enable

Automatic switching is enabled, when the light is weak, it will automatically switch to the electric supply, and the MPPT function is disabled at this time.

P47.03 Automatic start timing In auto start mode, set the time from power on to start. It is also waiting time to start 600
P47.04 MPPT starting voltage

Set the starting voltage of the MPPT algorithm.

When the MPPT function is disabled, this value is the reference voltage.

P47.05 Light detection threshold

If the output frequency is lower than this value and exceeds P47.06, it will be reported to Sleep and stop

If automatic switching is enabled, it will switch to ac grid operation, and the MPPT function will be disabled

P47.06 Light detection time See P47.05 for explanation. 60s
P47.07 Light weak wake up time

After the sleep fault is reported, if the time when Vdc is higher than the undervoltage point is greater than the set value, the fault state is exited and the operation continues.

When the automatic switching is enabled, after switching into the electric supply operation for this time, it will try to switch into the photovoltaic operation.

P47.08 MPPT tracking step length The amount of change in the bus voltage during an MPPT cycle. The larger the value, the faster the maximum power point is found, but the lower the accuracy of the maximum power point. 2V
P47.09 Regulator proportional gain 0.001~1.00 It is for immediate response speed, it is not recommended to change 0.05
P47.10 Regulator integral gain 0.001~0.100 tracking response.it is not recommended to change 0.05
P47.28 Starting coefficient 0.000~1.000 0.850
P47.30 Fast speed function
