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 200kW.
● 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.
