Default Rapid shutdown (off-grid, Manitoba Canada)

I'm trying to determine real-world requirements for rapid shutdown in small "cottage" off-grid systems in Manitoba, Canada.

If you're off-grid, code compliance falls to the Office of the Fire Commissioner. As far as I can tell, there is currently (no pun intended, but I'll pretend it was) only one guy covering electrical inspections for the entire province(?!)

I've read the codes, but there seems to be little clear distinction made between (relatively) high voltage grid-connected systems and (relatively) low voltage (e.g. 48V array) small-scale systems.

Just looking for practical information on-line has been frustrating.

I'm trying to sort out whether it is adequate to have an externally-accessible disconnect for an array that is not mounted on the dwelling, or do I need a full-on rapid shutdown system that disconnects the array and batteries remotely.

Anyone have any links, experience, commiseration...
