If the inverter detects the fault signal, it will enter into the fault pre-alarm displaying state. The
keypad will display the fault code by flicking. The TRIP LED on the keypad is on, and the fault
reset can be operated by the STOP/RST on the keypad, control terminals or communication
commands.

4.2.4. Displayed state of function codes editing

In the state of stopping, running or fault, press PRG/ESC to enter into the editing state (if there
is a password, see P07.00). The editing state is displayed on two classes of menu, and the

4.3. Keypad operation
Operate the inverter via operation panel. See the detailed structure description of function
codes in the brief diagram of function codes.

4.3.1. How to modify the function codes of the inverter

The inverter has three levels menu, which are:
1. Group number of function code (first-level menu)
2. Tab of function code (second-level menu)

3. Set value of function code (third-level menu)

Remarks: Press both the PRG/ESC and the DATA/ENT can return to the second-level menu
from the third-level menu. The difference is: pressing DATA/ENT will save the set parameters
into the control panel, and then return to the second-level menu with shifting to the next
function code automatically; while pressing PRG/ESC will directly return to the second-level
menu without saving the parameters, and keep staying at the current function code.
Under the third-level menu, if the parameter has no flickering bit, it means the function code
cannot be modified. The possible reasons could be:
1) This function code is not modifiable parameter, such as actual detected parameter,
operation records and so on;
2) This function code is not modifiable in running state, but modifiable in stop state.

Example: Set function code P00.01 from 0 to 1.

Restar Solar pump inverters Commissioning guidelines

5. Commissioning guidelines
 Disconnect all power supplies applied to the inverter before the terminal
wiring and wait for at least the designated time after disconnecting the
power supply.
 High voltage is present inside the inverter during running. Do not carry out
any operation except for the keypad setting.
 The inverter automatically runs once power on. If parameters need to be
set, follow the guidelines in this chapter.
5.1. Inspection before operation
Before powering on the inverter, ensure that:
 The inverter is grounded reliably.
 The wiring is correct and reliable.
 The AC/DC breaker is selected correctly.
 The PV input voltage is in the allowed range of the inverter.
 The type, voltage, and power of the motor match those of the inverter.
5.2. Trial run
Close the DC breaker. The inverter automatically runs with a delay of 10 seconds. Check the
water yield of the pump. If the water yield is normal, the trial run is successful. If the water yield
is under the normal value, exchange any two motor cables, connect the cables, and perform
trial run again.
5.3. Parameter settings
The inverter automatically runs by default once being powered on. If you want to set
parameters, press QUICK/JOG within 10 seconds since the inverter power-on to switch to the
keypad control mode (LOCAL/REMOT is off) and then set parameters. If the running indicator
is already on after the inverter is powered on, press STOP/RST to enter the parameter setting
mode. After parameter setting, turn off and then turn on the power switch. The inverter runs
again.
5.4. Advanced settings
Note: The default settings of the inverter for the water pump can apply to most conditions and
the advanced settings are not required in most cases.
5.4.1. PI adjustment to the water yield
If the user requires large or low water yield, it is necessary to adjust PI (P15.06~P15.10)
properly. The bigger PI parameters, the stronger the effect is, but the frequency fluctuation of
the motor is bigger. In reserve, the lower the water yield is, the more stable the motor
-22-
Restar Solar pump inverters Commissioning guidelines

frequency is.
5.4.2. Special settings for single phase motors
a) When the single phase motor is in bad running performance, the user can adjust P04 VF
curve settings: set P04.00=1 and set P04.03~P04.08 to appropriate values according to
commissioning conditions; increase the voltage if the motor cannot start and decrease the
voltage if the current is high.
b) When the light is normal and the system starts slowly, increase P15.28 initial voltage
differential value appropriately.
c) For single phase motors with two-phase control (capacitor-removing):
① The maximum voltage needs to be less than 1/1.6 of the bus voltage. It is recommended to
set the rated voltage P02.04 less than 200V, or limit the maximum voltage output by multi-dot
V/F curve.
② Observe the currents of the windings through P17.38 and P17.39, the switched current is
the combination current of the two windings. The impedances of the windings are different, so
the currents are different at the same voltage output.
③ P04.35 can be used to change the output currents of the main and secondary windings. It
is recommended that qualified engineers perform adjustment since the voltage adjustment is
associated with motor design parameters. Otherwise, the motor performance may be
impacted.

Note:
 The time when the pump inverter operated to the lower limit of PI output frequency after
inverter start-up is determined by the ACC time.
 Delay time counting follows the rules if multiple fault conditions are met simutaneously:
For example, if all fault conditions of weak light, full water, and underload are met at the
same time, the inverter will count the delay time for each fault independently. If the delay
time of a fault is reached, the fault is reported. The delay time counting of the other two
faults keeps. If the reported fault is resolved but the conditions of the other two faults
persist, the delay time counting of the other two faults continues. If a fault condition is not
met during counting, the delay time of this fault is cleared.

Do as follows after the inverter encounters a fault:
1. Check to ensure there is nothing wrong with the keypad. If not, please contact with the local
SHINY office.
2. If there is nothing wrong, please check P07 and ensure the corresponding recorded fault
parameters to confirm the real state when the current fault occurs by all parameters.
3. See the following table for detailed solution and check the corresponding abnormal state.
4. Eliminate the fault and ask for relative help.

Note:
For the cable selection for model IP54, see the cables applicable to the models with the same
power as model IP54 in this table.
It is appropriate to use the recommended cable size under 40°C and rated current. The wiring
distance should be no more than 100m.

Restar Solar pump inverters Options and use

If the control cable and power cable must cross, the angle between them must be 90°.
If the inside of the inverter is moist, the insulation resistance will decrease. If there is moisture
in the inverter, dry up the inverter and measure the humidity again.
A.4. Reactors
If the distance between the inverter and the motor is longer than 50m, frequent overcurrent
protection may occur to the inverter because of high leakage current caused by parasitic
capacitance effects from the long cables to the ground. In order to avoid the damage of the
motor insulation, it is necessary to add reactor compensation. If the distance between the
inverter and motor is 50~100m, see the table below for model selection; if it exceeds 100m,
consult with SHINY technical support.
