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.

Noted: We suggest solar panel power should be 1.3-1.4 times higher than solar pump power ,and solar pump inverter power should be higher level than solar pump. When solar pump distance to inverter higher than 100m,it should be equipped with Output reactor or higher level power inverter .for Solar panel,l total VOC less than Maximum DC voltage of inverter and Solar panel vmp is recommend 530V for 380V pump and 305V for 220V pump
1. How to achieve Automatic start after stop?
If it is controlled by keyboard no need to set any parameter. If you want to control by external switch
As the default control mode is keypad control, First set P00.06=1 and use a wire or switch to connect com and DI1,When the switch is closed, the drive run, when the switch is open, the drive stop
2. 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
3. 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
