    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!

    It’s very good! LCD options make it much easier to use. That’s the strong point, easy of use. And robust. Great PC software.

    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.

Product Description

4KW 5.5KW 7.5KW VFD Solar Inverter For Solar Irrigation System


Features OF VFD Solar Inverter:


Trial run(How to start solar pump inverter)
Make sure all cables connections of solar panel and pump motor correct and no need to set any parameter, if you want to set parameter, you can do as follows.
1) (Keypad control):Set motor parameter P11.02- P11.06 as per motor pump name plate If dry run protection is required, measure the unload protection current(see details in user manual chapter for dry run function) If dry run protection not required then miss this step and go to step 2.
2) Set other related special solar pump parameters for optimization if needed.
3) After trial run finishing, if motor pump still not output water when inverter is running more than 40 Hz. Please disconnect the power supply and replace any two-phase wiring of the motor.

1) Support Maximum mppt efficiency which can be up to 99%
2) Special solar mppt mode and PID mode which most products can not achieve in China
3) Support LCD display with English and Spanish
4) Support GPRS remote control
5) Support hybrid AC and DCSupport Marco mode
6) Support dry run protection
7) Support full water and low water protectionSupport one button to switch AC

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
