    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!

    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.

22KW Variable Frequency Drive

Product Description

380V 440V 18.5KW 22KW Solar Pump Inverter With LCD Keyboard Display


Excellent software:

1, Auto MPPT more than 99%.
2, No need set any parameterit is very good control for voltage, and Automatic start and stop.
3, Can automatically stop the pump when the tank is full
4, Also can automatically stop pump when there have no water inside the well
5, Different from many competitors, our inverter support minimum power protection and maximum current protection to ADAPT to different pump requirements.

For example, frequent start and stop at low voltage is not good for pump so you can let inverter sleep to make pump stop or work only in the minimum frequency

High quality hardware:

1, Support both DC/AC input and 220V level
2, Support both single phase output and three phase output
3, Built-in C3 EMC filter for better harmonic and VDR grounding conforming
4, Widely working voltage can work as low as 350V-800VDC for 380V level and 200-410VDC for 220V level
5, Support input power from solar panels, on-grid power, generator..
6, Can be used with solar panels in day time, at night with on-grid power or generator
7, Can switch between solar panels and on-grid power automatically
