    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.

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.

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 0Hz
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. 600s
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

Energy Saving 3 Phase Solar Pump Inverter GPRS Monitoring Control Via PC And Mobile 3




1. Does the product need to set a lot of parameters?


No, it doesn't. The inverter has a self-adaptive and self-learning function. It is automatic start and stop, you can press Run key to start, or you just wait for P47.03=600S(Default) then it will automatically start


2. Could it replace my previous PV pumping inverter?


Yes, of course. Selecting inverter model according to the rated voltage, current and power of the water pump. A bit more is better. Then take off the old one and put ours on, the system will work.


3. How to design solar PV water pump system?


Key point: the rated VOC and VMP and power of the PV Array need to match the input range of the inverter. If needed, we will provide technical support online.


4. How to make the water pump system work without sunshine?


Usually, solar PV water pump system can meet the needs of pumping water.

If there is no sunshine, the system will not work. But out inverter could also support AC input. So, connect the power grid or diesel power generation to the inverter, the pumping system will work. If necessary, keep switch and interface locations during the system design
