The OBFRS-ESW1 is an Emergency Shutoff Switch that is used to turn the solar array on and off. It comes with a 120 VAC to 24 VDC power supply capable of powering up to 40 FireRaptors. If the 120 VAC power to the unit is off the system will shutdown automatically. If the manual button is pushed the system will shutdown. A 48 VDC to 24 VDC power supply can be substituted for the AC to DC power supply that comes with the ESW1 for a more reliable manual shutdown for systems with backup power. Emergency shutoff switches from other systems can be substituted for the ESW1. For OutBack this can be the RSI, and for MidNite the MNBirdhouse. Using the Aux contact closure in those switches will shut off power to the FireRators on rapid shutdown, serving the same purpose as the ESW1. This is helpful for systems with charge controls that require a disconnect at the charge control end of the circuit because the FireRaptor system will not serve that function directly.
If your modules will never exceed 40 VDC under any conditions, you can use two modules in series for each OBFRS-01 unit (code requires a maximum of 80 VDC in the array on shutdown). The FireRaptor OBFRS-01 does not have any monitoring or optimization.
