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:
● Worldwide applicable voltage levels and power ranges
Supports 220V single/three-phase, 380V three-phase water pumps,
power ranges from 0.75kW to 710kW.
● Fully intelligent
Simply connect the photovoltaic panels to the inverter, no need to
set any parameters and the water pump will start automatically when
powered on.
Automatic adjustment of the water output in response to changes in
sunlight.
Automatic dormancy in weak light (e.g. after sunset), withdrawal
from dormancy in strong light (e.g. at sunrise).
Automatic dormancy when the water level is high and automatic
restart when the water level is low, enabling automatic water level
control.
Specially designed for water pump users, easy to operate and
adaptable to various applications.
● Multiple protection
Protection features such as PV over-voltage protection, PV reverse
polarity alarm, automatic over-temperature derating, etc. can
effectively extend the product life
● Advanced MPPT technology
Ensures solar tracking efficiency up to 99%
● AC/DC switching solution
The whole series of products can automatically switch between PV DC
input and grid AC input, which can meet 24-hour water consumption
and no manual operation is required.

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 |
