US region codes for schneider xw pro

[Scat]

I am interested in the Schneider XW Pro.
and as watching: David Poz - Schneider XW PRO 6848 Inverter - Firmware Update on Schneider XW and Insight, off grid solar

He entered a code that is the file below, as he is off grid.
but how to we find a the code for where we are?

page 77 of the file: Schneider XW-Pro-NA-Installation-Guide_990-91228.pdf

www.solar-electric.com/lib/wind-sun/XW Pro NA Installation Guide (990-91228C-01).pdf

States:
2. Select the appropriate region grid code from the Select Region pull-down menu.
a. For grid interactive systems, the appropriate grid code is specified by the
utility in their interconnection rules.
b. For AC-coupled systems, ensure that the AC coupled PV inverters are set to
the same grid code.
c. Note, off-grid systems may typically use any of the grid codes. For off-grid
AC coupled systems, the California Rule no. 21-2018 grid code is
recommended for the XW Pro and PV inverters. The region code selected
must not be None.

If you are on grid, what is entered in this for the US and for Florida?

Thanks
Any help would be appreciated.

If you are on grid, what is entered in this for the US and for Florida?

California Rule 21 is the most popular, copied by many other utilities in other states.

But it's your utility that would tell you which mode they want, or that they don't care. Not necessarily a statewide thing.
