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.
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. How to design solar PV water pump system?
Key point: the rated VOC and VMP and power of the PV Array need to match the input range of
the inverter. If needed, we will provide technical support online.
3. How to use a float in the water tank to stop the pump if the tank is full?
If your float signal is digital signal Use float switch to short DI 3 and com ,see diagram 1.3
4. How to set minimum frequency ( for example) 30hz and maximum 50HZ
Set P47.05=30HZ and 47.06 to some time and 47.07 to some time. Please refer to details of P47.05-47.07
5. If pump is 60HZ frequency, how to set max frequency?
Notice: If your motor rated frequency is 60HZ First solution for you, P01.06=P01.08=P11.05=60HZ.
Quick setting and easier way: you should set P00.11=02 If your motor is three phase; if your motor is single
phase with capacitor ,set P00.11=22;If your motor is single phase without capacitor ,set P00.11=32
