Fire raptor will provide rapid shutdown at module level. Midnight also has the SOB. FireRaptor requires a control cable two wire, which can be powered by a 24 volt AC or a DC source. The Midnight SOB uses PLC from an AC or DC source. Outback uses the FireRaptor the two wire cable daisy chains and the presence of voltage on the cable closes the series circuit. I asked after their webinar if a single raptor could open several modules in series, I was told yes but I do not belive it. Ibelieve it is a single module device. I was told the two wire cable is isloated for up to 600 Volts, (maybe they said 1,000 V.) such that I could use one raptor conrtroller on two strings.
Code requires shutdown at module level for arc fault also, 690.11, for all unintended arcs this will mandate module level for parallel arcs, To be code compliant the charge controller for DC coupled systems, must have arc fault and a way to connect to the Fire Raptor string Perhaps for smaller off grid, go to low voltage where arc fault is not required. or use a classic CC which has Arc Fault, but I do not know how to get a shutdown signal from the classic.
