For Rapid Shutdown, I started using Midnite's BOS system, it can be set
up on a string level or module level (2019) with enough receivers.
While it doesn't work with most charge controllers right now, it does
work with the Magnum PT100 oddly enough. We haven't had any glitches,
the RS worked with very little fanfare. My biggest peeve is that the
transmitter either runs on 120 vac or 12 vdc, so we set up a DC to DC
converter. Midnite really needs 24 v and 48 v versions of the
transmitter. I don't want to use 120 vac, because then array charging
becomes dependent on inverter operation. If the inverter shuts down due
to low battery, you're back into the battery death spiral problem
inherent to AC coupled systems.

I'm not quite sure on the Rapid Shut Down. I am quite sure that they
have a compatible Rapid Shut Down solution that will suffice for about
1 month and 7 days but after 2019................................. I'm
not quite sure what we'll do... If anyone else can answer this
question, that would be awesome!
