panel of the inverter to stop the inverter and turn OFF the "RUN" light.
Disconnect the DC input of the PHOTOVOLTAIC array, connect the AC input,
and repeat the above operation.
Note！
● Output power of inverter drives the pump working; the pump will stop
working while the inverter stops.
● for the first test run, if there is any abnormality, the inverter will report a fault, please
refer to "9.1 troubleshooting" section.
●
System commissioning, may be abnormal, such as no flow, or flow rate cannot
reach the designed value, or even the three phase water pump issued by abnormal
sound. Please kindly check below:
a) Three-phase AC pump reversal (saying three-phase pump connected wrong),
you need to stop and set “M-Mode”, please refer to the Chapter “8.3.2.3 DSP
Parameter Settings” and “8.3.4 Parameter Settings”;
b) Output power of PV module is too weak;
7.3 Stop Frequency Setting
Solar pump system for the first time trial run is successful, need to set the system
shutdown frequency, as follows.
Step 1: Ensure the system is running and there has water output. To enter “StopFreq”
interface. Please refer to"8.3.2.3 DSP Parameter Settings" "8.3.4
parameters" .
Step 2: To reduce the value of “StopFreq”. Reduce 5 each time (every change need to
press “ENTER” to confirm). Keep reducing till there just has no water output, and
make a small change to just get small water come out, and the value is the very
data of “StopFreq”.
Step 3: Exit the “StopFreq” interface.
