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.

|P47.00||Solar pump Mppt function enable||
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=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.

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
