4. OPERATION AND CONTROL

4.1 Initial Settings before First Operation
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
Modify all control parameters as read-

Operating Method
Modify Pr.0 value to 0.
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 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 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
access.
If the water level switch is not required, this step can be
skipped else set according to description of Pr.15-Pr.18.
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.
