Disconnect the DC input of the PHOTOVOLTAIC array, connect the AC input,
and repeat the above operation.
Note
！
●
Inverter operation refers to the output power of the inverter, drive the
pump to work, inverter shutdown refers to the inverter to stop output
power, the pump to stop working.
●
When the output is connected to three-phase pump, and the system is in
trial operation, if there is no water coming out, the flow rate cannot reach
the designed flow rate, or even the three-phase AC pump in the solar
pump system of the user sends out abnormal sound. Possible reasons are
as follows:
●
A) Reverse of the three-phase AC pump, that is, reverse of the
three-phase phase sequence, stop the machine and enter the setting
interface of " M-Mode " of the inverter. Please refer to the chapters of
"8.3.2.3 DSP Parameter Setting" and "8.3.4 Parameter Setting".
●
B) The output power of PV array is too small.
●
For the first trial run, if there is an abnormal situation and the inverter
reports failure, please refer to the chapter "9.1 Troubleshooting".
7.3 Stop Frequency Setting
Solar pumping system for the first 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 “8.3.2.2 DSP Parameters Setting” and
“
8.3.4
Parameter Setting”.
