4.1 Initial Settings before First Operation
4. OPERATION AND CONTROL
While implementing initial settings below, refer to section 4.6 on how to view and
modify parameters as well as section 4.7 for detailed parameter descriptions
Step
Initial Setting Content Operating Method
1
Modify Pr.0 value to 0.
Modify all control parameters as read-
write parameters.
2
Modify Pr.9~Pr.10 (hour, minute) according to local
time.
Note: Do not use the inverter without setting the
time else records will be incorrect. If the built-in
communication module is selected, the time
setting can be synchronized through the APP.
Modify date and time
3
Modify Pr.2 parameter (open circuit voltage) according
to the solar array.
Note: Inverter may work without modifying
Pr.2, but will work better after modifying Pr.2
especially where array VOC is greater than
700V. Set Pr2 to 0.85 of rated VOC of array.
Modify Solar array parameter
4
Modify Pr.3/4/5/13 value according to the rated
parameters of the pump. For single phase pumps wired
with capacitors, also modify Pr153 value to 0. For single
phase pump without capacitor, modify Pr0 value to 4
Note: Pr153 is accessible in advanced settings
mode. Change parameter 30 to 11520 to
access.
Modify rated voltage, current,
frequency and power parameters of
the pump
5
If the water level switch is not required, this step can be
skipped else set according to description of Pr.15-Pr.18.
Modify the water level switch
settings
6
1. Modify Pr.7 value as 0, enable the frequency setting
from panel
2. Press RUN key and observe water yield from the outlet
3. Press STOP key and exchange any pair of pump cable
connections with the inverter
4. Press RUN key and observe water yield from the outlet
again
5. Press STOP key, select the wiring method with bigger
water yield to ensure the motor is rotating forwards.
