HI Dan and Kienan,
Yea I understand some of the work arounds, but its not always possible to work around things. At some point its going to be in a building or on the roof etc.
So sounds like from the crickets that things are not quite ready yet. Better slow and ready than fast and not.
thx
jay

I know that this doesn't answer the question... but my only comment is to use a pole mount whenever possible. Rapid shutdown only applies to systems on a building or where the PV system conductors penetrate beyond 3' into a building before reaching the PV system disconnect. For a pole mount, as long as your equipment is on the outside wall, you can easily get to the PV system disconnect within 3' of wire length from the building penetration so no rapid shutdown of any kind is required. The battery system is considered a separate system in the 2017 code and there is no requirement for rapid shutdown of any kind in that system.
