1. VEIKONG solar water pump system is essentially an electrical
pump system in which the electricity is provided by one or several
PhotoVoltaic (PV) panels. A typical solar powered pumping system
consists of a solar panel array that powers an electric motor,
which in turn powers a bore or surface pump.
2. What is solar pump inverter?
A solar inverter or PV inverter,solar pump inverter,solar pump
controller,solar water pump inverter,solar pump drive,solar water
pump controller,solar mppt vfd,solar mppt frequency inverter,solar
frequency inverter,solar pump vsd,solar frequency inverter,solar
vfd are all key words
IT is a type of electrical converter which converts the variable
direct current (DC) output of a photovoltaic (PV) solar panel into
a utility frequency alternating current (AC) that can be fed into a
commercial electrical grid or used by a local, off-grid electrical
network.
It is able to convert DC voltage coming from solar panels into AC
voltage for powering any pump driven by a three-phase motor.
Pump speed is constantly adapted to available solar irradiation
thus maximising the amount of pumped water and making possible
operation even in conditions of low sunlight.
It also offers complete pump protection against surges, overloads
and dry running.

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.

Product Application
Quality Control
VEIKONG solar pump VFDs have passed comprehensive test process
during manufacturing.
R&D test: test the hardware and software performance, to make
the design more optimization, makes sure the products have
excellent
performance before production;
Board test: test the performance of every board in our products, to
reduce product defective rate;
IQC: take strict quality inspection for every income components, to
ensure every income components are qualified.
Aging test: make the solar pump VFDs at run status, put them in the
aging test house at 50°C for 48 hours, to remove every unqualified
products.
Load test: the last and the most important test, add different load
to the solar pump VFDs, test their input and output value, to check
their
working performance. unqualified products will be removed from the
team.
By applying such strict testing process, VEIKONG ensures every
outgoing solar pump VFD has excellent quality.
FAQ
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
6. How to make the water pump system work without sunshine?
Usually, solar PV water pump system can meet the needs of pumping
water.
If there is no sunshine, the system will not work. But out inverter
could also support AC input. So, connect the power grid or diesel
power generation to the inverter, the pumping system will work. If
necessary, keep switch and interface locations during the system
design
7. 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
