    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.

    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

Solar pump inverter 18.5kw 22kw 220V single phase for agricultural irrigation



Key Advantages:

1. MPPT efficiency more than 99%.

2. Drives well all 1/3 phase AC pumps and PMSM in solar pumping system.
3. Voc of solar panel can set by manual or MPPT automatically tracking.
4. Solar DC & Grid AC power supply input both ok.
5. Dry run & Full water tank protection.
6. Short circuit, over load, over current... motor production.
7. The PQ (power/flow) performance curve enables calculating the flow output from the pump
8. Ambient temperature for using: -10 to +50˚C.
9. Inverter Power range: 220V, 0.75KW to 110KW. 380V/480V, 0.75KW to 250kw


Techincal Parameters:


1. Wake up and sleep function parameters:


P47.05 Light detection threshold If the output frequency is lower than this value and exceeds P47.06, it will be reported to Sleep and stop 0Hz
P47.06 Light detection time See P47.05 for explanation. 60s
P47.07 Light weak wake up time After the sleep fault is reported, if the time when Vdc is higher than the undervoltage point is greater than the set value, the fault state is exited and the operation continues. 600s


2. Dry runing protection function parameters:


P24.12 Dry run/Unload protection option

0: No offload detection is performed;

1: Enable dry run detection

P24.13 Dry run/Unload detection level

0.0 to 200.0%

The percentage of motor rated current.

P24.14 Dry run Unload detection time 0.000s~60.000s 30.000s
P24.15 Unload detection offset frequency


Detection frequency=Fmax-P24.15


P24.16 Reset time of dry run protection 0.0~6000.0 240.0s
P23.21 Dry run detection mode

0000:Coast stop

1000:Fast stop

3000:Continue to run



3. Water full protection function parameters:


P47.18 Full water level detection channel






Note: DI terminal function code 60-full water level detection is same with Analogue detection, and the detection time and recovery time are the same.

P47.19 Full water level detection value




P47.20 Full water level detection time


When DI-60 is valid or meets the analog detection channel greater than P47.19 and maintains P47.20 time, the system reports A.Full and stops.


P47.21 Full water recovery time


When the condition described in P47.20 does not meet full water level detection requirement ,it will be returned to normal state after delay
