(PVI-DESKTOP-yy-xx Rev: 1.2)
• If you decide to carry out the scan, the PVI-DESKTOP will begin to
interrogate the various addresses until has found a number of inverters
corresponding to the one set in the configuration process. During scanning, a
screen showing a table with an indication of the state of scanning will appear.
• At the end of scanning, the table will show the models and serial numbers of
the inverters found.
• At this point it is possible to choose which inverter(s) to associate uniquely
with your PVI-DESKTOP so that they cannot be seen and recognised by
other PVI-DESKTOPs nearby. The selection is made by pressing the '+' key
next to each inverter chosen. Pressing the '+' key changes the colour of the
corresponding row in the table by highlighting the selection.
• It is advisable to check that the serial numbers of the inverters chosen
correspond to those of the inverters in your system to avoid associating
inverters from other systems nearby with your PVI-DESKTOP.
• At this point the system is configured and, automatically, starts the
synchronization procedure for the timetable of the monitored inverters and
data acquisition from the inverters. The first synchronization can also take a
very long time because of the high amount of historical data that the inverters
will send to the PVI-DESKTOP.
• On the other hand, if the channel scan is unsuccessful, an error message and a
request to repeat the scan will be displayed.
• To determine the causes of non-recognition of the inverters, consult the
troubleshooting guide attached to the manual
3) Inverter disassociation or need for reconfiguration
Whenever it may be necessary to delete one or more associated inverters from your
list, it is necessary to run the guided procedure again, accessing it from the “Settings –
Configuration wizard" menu. On appearance of the table with the associated serial
numbers, simply click on the '-' key to deselect the inverter and delete it from the
associated list.
Any time a re-configuration is necessary, you must carry out the guided procedure.
NOTE: The guided configuration procedure is necessary, for example, when
an inverter is replaced or an inverter is added for monitoring.
