When installing the String Supervisor, it is necessary to make some adjustments on the main screen in
order to display data on the screen. The following adjustments will be made:

Change parameter [G1.12 String Connected] to YES.

In the [G10.3.1 Bus Select] parameter, select CAN if working with Freesun LVT, or RS485 if
working with Freesun HE or HES. The appropriate choice of the selection involves the wiring
installation as described in this manual (either CAN or RS485 communication).

Once the changes in the settings are done, it is necessary to disconnect the auxiliary supply from
the control board and reconnect it in order for the changes to take effect.
The following step is to detect the String Supervisor devices:

In the subgroup G10.1, click on [Scan the Bus] and wait 30 seconds. If everything is configured
correctly, the number of String Supervisors connected to the inverter will appear. Click on [Save
the new Configuration].

After this, in the String Supervisor Visualization group and in the G10.2 subgroup, after saving the
settings in G10.1 two IDs of the String Supervisor (SS ID) will appear. These IDs can be seen
clicking on [Prev SS] or [Next SS].
