Resurrecting this old thread with some news...
There is some drama going on regarding the use of Generac "SnapRS" disconnects... from what I can tell Generac complete PV+ESS systems use these in-line disconnects on each DC-coupled PV panel that are triggered by the inverter. This is in lieu of the blade disconnect (like my avatar) to rapidly shutdown the PV.
I guess the drama is that a regional solar company Pink Energy is claiming Generac's systems are not reliable. Generac contends Pink Energy didn't install the equipment correctly. But regardless who is to blame, homeowners who aren't experts in PV+ESS are left bag-holding with systems that don't work and nobody to service the system.
I think if you're in the market for a Generac PV+ESS, it would make sense to simply ask your installer to not use the SnapRS and still achieve NEC 2017 rapid shutdown requirements using my favorite blade disconnect. It's not that I dislike blade disconnects; it's that I hate a bunch of blade disconnects that seem redundantly redundant.
