Chapter 1 Products Introduction
1.1 Introduction of Solar Pumping System
Solar pumping systems produced by Shenzhen JFY Tech.Co.,Ltd can be applied
to daily use (underground water), agricultural irrigation, forestry irrigation, desert
control, pasture animal husbandry, water supply for islands, wastewater treatment
engineering, and so on. In recent years, with the promotion of the utilization of new
energy resources, solar pumping systems are more and more used in municipal
engineering, city centre squares, parks, tourist sites, resorts and hotels, the landscapes
and fountain systems in the residential areas.
The system is composed of a solar array, a pump and a solar pumping inverter
(see figure 1-1). Based on the design philosophy that it is better to store water than
electricity, there is no energy storing device such as storage battery in the system.
Fig. 1-1 Structure of solar pumping system
The PV array, an aggregation of many PV modules connected in series and in
parallel, absorbs sunlight radiation and converts it into electrical energy, providing
dynamical power for the whole system. The pumping inverter controls and adjusts the
system operation and converts the DC produced by the PV array into AC to drive the

pump, and adjusts the output frequency in real-time according to the variation of
sunlight intensity to realize the maximum power point tracking (MPPT). The pump,
driven by 3-phase AC motor, can draw water from the deep wells or rivers and lakes
to pour into the storage tank or reservoir, or directly connect to the irrigation system,
fountain system, etc. According to the actual system demand and installation
condition, different types of pumps such as centrifugal pump, axial flow pump, mixed
flow pump or deep well pump can be used.
1.2 JFY Solar Pumping Inverter Features
Based on many years of development and experiment, the self-developed
pumping inverter (figure 1-1) by our company has the following features:
Adopting the proposed dynamic VI maximum power point tracking (MPPT)
control method which has independent intellectual property; Fast response speed and
stable operation; Better than the conventional methods which may lead to the
problems including poor tracking performances, unstable operation or even damaging
water hammer effects when the irradiation on the array changes rapidly.

Operation Control
3.2 Setting and Operating
Inverter start-up and operation
Step 1: Ensure that the DC cable is connected correctly; unused DC plugs and
AC terminal cover is sealed.
Step 2: Connect the solar pump to the AC output terminals (see Fig.2-2). If
there have a AC switch between the pump and inverter (not suggest), Ensure the AC
switch is ON.
Step 3: Connect the PV array to the PV input terminals before ensure the DC
switch is OFF (see Fig.2-2).
Warning: It`s absolutely forbidden to turn on the AC switch when the inverter
is working, or may broken the inverter. The smart mind is turn off the DC switch first,
wait 5 minutes at least to avoid risk of electric shock from energy stored in capacitor,
then turn on the AC switch, and turn on the DC switch at last.
Ensure all the wires is corrected connect, turn on the DC switch, the LCD
display and power light will bright; then the inverter will drive the pump for wait 60
seconds.
Caution: There are two operation modes in the product; the factory set is
full-automatic operation:
1: Press
key to operate, the initial frequency value is determined by
S00.10, and then modifies the output frequency by pressing Increment key or
Decrement key. In this mode: it`s need to press
key to operate and long press
2s to stop.
2: Full-automatic operation: the inverter will start automatically if the sunlight is
strong enough, the output frequency will track automatically according to the sunlight.
The control cell array will export maximum power; in this mode, it isn`t need to

Operation Control
control the inverter, it will start automatically if the sunlight is strong enough and
stop when the sunlight is weak. It could only view running data and parameter, and
use DC switch to control the inverter if you want.
Once the solar pump inverter starts, it enters one of the following 3 states in
turn:
Standby: The PV array can only provide just enough voltage to minimum
requirements of the internal controller unit.
Try to working: When the PV array DC voltage is greater than 500V, the
inverter will try to working.
Normal: when the inverter operates and the PV array DC voltage is greater than
500V, the inverter will work normally.
The Inverter will keep MPPT function and drive the solar pump when it is in
normal operation. Maybe it will stop under the situation of low input DC-power,
don’t worry, it will automatically restart again when DC-power from the PV array is
sufficient.
Warning: The rated power of the pump exceed the inverter, it may broken the
inverter; if the rated power of the pump match the inverter, it isn`t need to edit the
parameter; if the rated power of the pump not exceed the inverter, it is need to edit the
parameter in following steps.
E.g. Inverter (7.5kW) drive the pump (5.5kW)

Fault Diagnosis
Chapter 4 Fault Diagnosis
4.1 Fault Code Description and Countermeasure
SPRING series solar pumping inverter has perfect protection. When the system
fault occurs, the inverter will take protection measures: general protection measure is
to stop driving signals output of the motor (breakaway) immediately while the restart
is forbidden for a certain period of time.
It will automatically switch to the fault display unit when fault or protection
occurs. The fault code will be displayed in the middle of the LCD and flash. You can
cut off the input power supply and get electricity until the internal power supply is cut.
If the fault still exists after reset, please contact the manufacturer and make relevant
processing.
After the fault or protection to be reset is eliminated, the inverter will conduct
automatically a time-delayed restart. At this time the fault number will appear in the
left side of the LCD. The right will display the countdown of the restart, when the
countdown is 0, fault display unit will disappear automatically and operating status
data will be displayed.

4.2 Fault Inquiry and Reset
This series of inverters record the fault codes of the latest 5 times. Searching this
information will help find the fault cause. Fault information is stored together with
the control parameter, code numbers are S07.28~S07.32. Please refer to the keyboard
operation method to search and find out relevant information.
Caution: Completely check up on the fault cause and eliminate it before reset.
If it cannot be reset or goes wrong after reset, check up on the cause, because
continuous reset will damage the inverter.
Caution: Delay 5 minutes to reset during overload and overheat protection.

Service and Maintenance
Chapter 5 Service and Maintenance
5.1 Routine Inspection and Maintenance
Affected by ambient temperature, humidity, dust, vibration and internal device
aging of the inverter, the inverter will appear some potential problems during
operation. To make the inverter run stably for longer time, a periodic inspect must be
exerted every year.
Requirement of Inspection and Maintenance
The inspection must be performed by professional technical personnel, if
necessary, cut off power supply of the inverter first.
Avoid leaving the metal components in the inverter, or else it will cause damage
to the equipment.
Electric insulation test has been made on the inverter before it is leaving factory,
so the user doesn’t have to carry on a withstand-voltage test.
If it is necessary to conduct insulation test on the inverter, all the input and
output terminals must be reliably shorted. It is forbidden to conduct insulation test on
single terminal. Use the 500V megohmmeter to conduct the test.
It is forbidden to use the megohmmeter to test in the control circuit.
When conducting insulation test on the motor, you have to dismantle the
connection between motor and inverter.
Main Points for Inspection and Maintenance
Please use the inverter under environment recommended by this manual. Inspect
and maintain as per the following table.

5.2 Inspection and Replacement of the Damageable Part
Filter Capacitor
Pulsating current of the main circuit will influence the performance of the
aluminum electrolytic filter capacitor, of which the degree will depend on the ambient
temperature and application condition. The inverter used under normal condition
should replace its electrolytic capacitor every 10 years. When the filter capacitor’s
electrolyte is leaking, safety valve bursting out or the capacitor main body expanding,
replace it immediately.
Cooling Fan
Of SPRING series of pumping inverter, all the inverters above SPRING 22kW
have cooling fans inside. Cooling fan’s service life is about 1, 5000 hours. If the fan
appears abnormal noise or produces vibration, replace it immediately.

Service and Maintenance
5.3 Storage and Warranty
Storage
If the storage is not used temporarily or stored for long time after purchasing, the
following notice should be paid attention to.
Avoid placing the inverter in high temperature or humid place or where there is
vibration and metal dust, and excellent ventilation should be ensured.
Inside filter capacitor performance of the inverter will decline for long–time
disuse. It is necessary to energize one time every 2 years to restore the performance
of the filter capacitor and inspect the inverter function at the same time. It is
necessary to increase the voltage through a DC power supply during energizing with
power-on time not less than 5 hours.
