I have read pages and pages of NEC regs, and am still unsure if the whole rapid shutdown system requirements even apply to all 12v systems.
I keep seeing "below 30v in under 30 seconds".
On a 12v system you can just connect the panels in parallel and stay under 30v.
Would a system done that way still need a rss control?
Series would be better with a mppt controller, but to avoid the rss extras it could stay under 30v in parallel.
