[RE-wrenches] Schneider Rapid shutdown with 2023 compliance

[Mac Lewis]

Hello Wrenches,

I need to retrofit a Schneider XW+ system with a rapid shutdown system.
The owner purchased this equipment about 4-5 years ago but is trying to get
it past a *very *intense inspector.

To me, it looks relatively straightforward to get NEC 2023 rapid shutdown
compliant using Tigo TS4AF, and adding Schneider's MPPT Disconnect RS and
external rapid shutdown initiator.  It's a little strange though because it
has 2017 NEC compliant all over the documentation but I believe we are good
through NEC 2023 because shutdown occurs at a module level and the
Disconnect RS can take care of arc-fault monitoring.

Does anyone have any documentation for the MPPT Disconnect RS that doesn't
specifically call out (only) NEC 2017 compliant?

Or if this is not a good approach and is not reliable, I would appreciate
your input as well.

Cheers!
