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.

MPPT means Maximum Power Point Tracking; it’s a special function for solar system, which is used to get the
maximum possible power from one or more photovoltaic devices, typically solar panels. Solar panels have a
complex relationship between solar irradiation, temperature and total resistance that produces a nonlinear output
efficiency which can be analyzed based on the I-V curve. It is the purpose of the MPPT system to sample the output
of the cells and apply the proper resistance (load) to obtain maximum power for any given environmental conditions.
By adopting this technology in the solar pump inverter, it increases the working efficiency of solar panels,
and also adjusts the output frequency of solar pump VFD based on the sunshine strength; make sure the system
always works at an optimum condition.

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,total VOC less than Maximum DC voltage of inverter and Solar panel vmp is recommend
530V for 380V pump and 305V for 220V pump.
VEIKONG VFD500-PV solar pump inverter Features:
R&D test: test the hardware and software performance, to make the design more optimization, makes sure the products have excellent
performance before production;
Board test: test the performance of every board in our products, to reduce product defective rate;
IQC: take strict quality inspection for every income components, to ensure every income components are qualified.
Aging test: make the solar pump VFDs at run status, put them in the aging test house at 50°C for 48 hours, to remove every unqualified products.
Load test: the last and the most important test, add different load to the solar pump VFDs, test their input and output value, to check their
working performance. unqualified products will be removed from the team.
By applying such strict testing process, VEIKONG ensures every outgoing solar pump VFD has excellent quality.
6. 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
