Will,
No problems with inspectors for us in MA, regarding rapid shutdown, since we recently switched to using SolarEdge central inverters with optimizer under each module, for roof mounted installs. 
So far so good. They seem well made and engineered. Tip: you have to enable the arc fault protection when commissioning, ships disabled.

In Mass we’re having all kinds of issues with inspectors requiring/allowing an array of different things for 690.12 rapid shut down ranging from roof top disconnects, disconnects on the side of a house 20’ up, disconnects in attics, or only disconnects that can be activated on the ground.  It varies between inspectors.
