    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.

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
