[RE-wrenches] Rapid Shutdown, was Re: [RE-outback skybox)

[Ray]

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.
