NC has an NEC interpretation problem that will affect all ESS systems

Oh fer cryin' out loud.
At least 702 does not actually say 'listed' and 750.6(3) has some options.

The options all seem to imply UL 916

750.6 Listing
Energy management systems shall be one of the following:
1) Listed as a complete energy management system
2) Listed as a kit for field installation in switch or overcurrent device enclosures
3) Listed individual components assembled as a system

The standard Generac RXSW200A3 200A ATS often included with the generator in a package deal from from home improvement stores has a included "Smart A/C Module (SACM)" load management system for "up to four individual HVAC (24 VAC controlled) loads with no additional hardware" which does not appear to meet any of the above 2023 NEC 750.6 options, not an issue until your on the 2023 NEC and by then they will probably update the products. But its an issue here.
The pwrcell line is 916 listed and does have upgrades to the standard transfer switch.

I'm don't think that option (3) requires a 916 listing.

I think we should also take into account that 2020 NEC 706.16F redirects to 710.15. Cant be much clearer than that.
