Re: [RE-wrenches] Schneider Rapid shutdown with 2023 compliance
You said that very nicely Kevin ! If this were for offgrid, I would make the inspector happy and do even more than Kevin suggests after he is gone.

Re: [RE-wrenches] Schneider Rapid shutdown with 2023 compliance
Note that the MPPT disco RS works only with Schneider charge controllers. With any other charge controllers you'll need to use Fire Raptors. Specifically the power line type rsd do not work with classic cc. I see no reason why the Schneider units would not meet 2020 or 2023 codes.

Re: [RE-wrenches] Schneider Rapid shutdown with 2023 compliance
I had a some way similar experience I used fire raptor and added a relay to use Raptor signal to shutdown inverter.
