I was just researching the NEC and stumbled on something I did not know.

Most of our DIY systems were not going to be 100% compliant anyway, but this sounds like it makes it impossible for a DIY to build an NEC compliant battery system... Is this other folks understanding as well?
For the most part I have learned that the NEC makes rules for good reason, but this sure feels like they were influenced by the makers of complete systems.

Also, Section 706.5 has been revised to simply state that ESS are to be listed. This is a significant change because now an ESS must be listed as a complete energy storage system and is no longer permitted to be made up of a field assembly of listed components.
