magnetic contactor can make inverter over-current protection function act. It will damage
frequency inverter seriously.
6. Please don't disassemble the panel cover, it only needs to disassemble the terminal cover
when wiring.
7. It is forbidden to do any pressure test on frequency inverter, otherwise it will damage the
frequency inverter.
●Before electrification
Danger
1. Please make sure that voltage grade of power supply is consistent with frequency inverter's
voltage and then check whether the wiring is correct and firm, and whether there is short
circuit in peripheral equipment's circuit. Otherwise it will damage frequency inverter and other
equipments.
2. Before the frequency inverter is connected to the input power supply, make sure that the
cover has been fixed well. Otherwise it will cause electric shock.
3. For the frequency inverters whose storage time is over 1 year, when electrification, the

Solar Pump Controller Manual

voltage should be raised by booster from low to high. Otherwise it will damage the frequency
inverter.
Attention
1. Check all periphery fittings are wired properly according to the handbook; Otherwise it will
cause accidents.
●After electrification
Danger
1. After electrified, it is forbidden to open the cover, make wiring, and check up; Otherwise, it will
cause the danger of electric shock.
2. After electrified, it is forbidden to contact internal wiring board and its parts. Otherwise it will
cause the danger of electric shock.
3. Do not operate or touch frequency inverter with wet hand. Otherwise there is danger of
damage to frequency inverter and electric shock.
Attention
1. Please set the parameter of frequency inverter cautiously; Otherwise it will damage
equipment.
●Operation
Danger
1. Before running, please check and confirm the application range of the machine and
equipments once more; Otherwise it will cause accidents.

3. Persons who have not passed specialized train are not allowed to conduct the frequency
inverter maintenance; Otherwise it may cause electric shock and damage the frequency
inverter.
1.3 Cautions in utilization
1. In application of this series frequency inverter, you have to confirm all machine insulation to
prevent damage to the equipment. Moreover, when the motor working in tough environment,
please periodic inspect the electrical insulation to ensure the safety of the system work.
2. If the motor adapter is not consistent with frequency inverter's rating current (The rating current
of the motor is far smaller than that of frequency inverter), please adjust the protective value to
ensure safe running.
3. In occasions such as load raising, usually there is negative torque and frequency inverter
breaks off for over-current or over-voltage. In this case, you should consider to choose the
matching brake unit.
4. Frequency inverter, in a certain output frequency range, can meet the mechanical resonance of
the load equipment. To avoid it, you can set up jumping frequency.
5. As output voltage of the inverter is pulse-wave type, if there is capacity which can improve
power factor or pressure-sensitive resistance which used for thunder-proof in the voltage
output side, the frequency inverter will break off or its parts will be damaged, so it is necessary
to dismantle them. Moreover, it is proposed not install switch parts like air switch and contactor
(if it is necessary to install switch on output side, please make sure the output electricity of
frequency inverter is zero when the switch is working)
6. At over 1,000 meters altitude, the inverter’s heat dissipation function worsened due to the thin
air, it is necessary to use less.
7. The inverter output voltage is pulse wave type. If using digital multimeter measurement,
deviation of the reading will be great. And the deviation is different by using different type of
digital multimeter. Under normal circumstances, while RMS 380V, digital multimeter reading is
around 450V.
8. Solar panel: many panels string or parallel. For rated voltage 380V controller, we suggest
working voltage between 480V to 560V while MPPT. What means the solar panel open circuit
voltage between 600V to 700V.

Chapter 3: Parameter Explain and Fault Process
3.1 Solar pump controller changes output frequency and calculates PV panel
output power in real-time, then compare output power to search maximum power.
1 .E-02(Frequency give main channel selection) set as 10 is solar pump control mode.
2. Automatic stop for alarm:
a. If F04 parameter set as 27 for solar pump control pause ( Input digital terminal X4 signal select
for solar pump stop function). When normal open termial X4 and COM is activated for close
condition, the solar pump working will be stop. It is used for water level alarm output and stop
the machine.
b. While the solar panel outputs low power, H-32 (Lowest run frequency),H-33(Lowest run
frequency duration time),H-34(Stop and wait time) can be set.
c. While input voltage is lower than run voltage. It will output valid signal if output terminals Y1,Y2
set as 1 : fault jump alarm1 and 2: fault jump alarm, the output signal is valid.
3. Start and accelerate to bus voltage and lower than upper limit voltage. After start, solar pump
controller makes bus voltage lower than upper limit voltage according to certain ACC speed. If
output frequency is still lower than H-32 lowest run frequency while it is lower than upper limit
voltage, it accelerates by E-13 ACC time.
4. Automatic dormancy parameter setting (Sleep mode setting); The solar pump controller enters
dormancy state while the input bus voltage is under H-35(Automatic dormancy voltage) and
runs again while the input bus voltage is bigger than H-36(Renew voltage in dormancy). If it
continuously runs under H-32 (lowest run frequency) ≤3 times, stop and wait time is H-34 set
time *1,If ≤6 times，stop and wait time is H-34 set time *4,If≤9 times, stop and wait time is H-34
set time *8,If ≤12 times，stop and wait time is H-34 set time *16,If ≥13 times，stop and wait time
is H-60 set time (default 15 minutes). H-61 can check the times. Adjust dormancy can change
H-34 set time.
5. Quick reduce frequency function: While bus voltage is bigger than H-35 (Automatic dormancy
voltage) and smaller than H-37 (Max MPPT voltage setting), output frequency quickly reduces
by H-59 (Quick reduce frequency ratio)
6. ACC/DEC time set explain
While the output frequency is lower than H-32 (lowest run frequency), it ACC/DEC according to
ACC/DEC time setting.
While the output frequency is higher than H-32 (lowest run frequency), it ACC/DEC according
to 0.1s ACC/DEC time.
