Hey Steve, Yes I'm reading that code article closely and I think its open to interpretation. If you consider PV circuits to include the battery based inverters, you would need to include them in rapid shutdown.
For some reason I thought it applied to all of the DC conductors, including the battery cabling, but it looks like that isn't explicitly called out. Midnites system does have a way to do it.. That will probably show up on the next code cycle. Thanks for pointing that out.
