    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.

The solar pump inverter is the most important equipment in the photovoltaic water pumping system and the soul of the system. Electrical energy from photovoltaic solar panels to drive AC motor water pumps.
Solar pump inverter that switches the DC power supply from the solar panels to the AC power needed to control the pump. With the solar inverter, pumps can adapt to solar energy sources rather than traditional power supplies or generators. Solar pumping system is a series-parallel absorb sunlight radiation energy through solar panels and convert it into AC power by inverter to drive centrifugal pump, irrigation pump, axial flow pump, mixed-flow pump of deep well water pump system.


1. GPRS (support 2g/3g/4g internet)
It supplies water volume monitoring and operation of inverter from anywhere at anytim
It’s convenient to visit real time and historical data via web or Android APP anytime and anywhere.
This easy-to-use platform makes monitoring of solar pump systems simple and convenient,
far reducing operate time and monitoring costs as well.

2. LCD keypad
Standard inverter are with LED keypad,LCD keypad is optional.
LCD keypad can monitor 4 parameters at the same time. LED keypad show one parameter only.
LCD keypad with detailed parameter explain,no need use user manual ,more user friendly.
LCD keypad with copy and update and download function.widely used for government projects and big farms.

1. How to check and solve basic problem of inverter trips and error
a:Check the total vmp and voc of solar panels ,solar panel technical data
b:Check motor pump power and rated current
c: Check the distance between motor and inverter
d: Check trip record r25.00 r25.01 25.02 25.03 r26.00 r26.01 r26.02 r26.03
e: Check troubleshooting fault and find relevant solutions
f : Check if motor insulation has been damaged or motor is blocked



For 220V single phase motor connection


1: Single phase asynchronous motor wiring method (without starting capacitor):

Notice: U is connected to the common end of the starting winding and the working winding, V is connected to the starting winding, and W is connected to the working winding;


Single-phase asynchronous motor if the rotary steering is not correct, you can change the V and W wiring or set P22.13=1.


First solution: Set parameter P11.01=1 (Single phase motor type without capacitor) or second solution: set P00.11=31 if your motor frequency is 50 hz or set P00.11=32 if your motor frequency is 60HZ



For 220V single phase motor connection


2:Single-phase asynchronous motor wiring method (with capacitor)


Notice1:First solution: Connect motor cable to power terminal U and V and enter BSC mode to Set parameter P23.15=0(output phase loss shielding protection) or second solution: set macro P00.11=21 if your motor frequency is 50HZ or set P00.11=22 if your motor frequency is 60HZ
