<p>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.<br>

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
