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! -- Mac Lewis *"Yo solo sé que no sé nada." -Sócrates*
