Each BFS-11 device operates multiple solar modules total voltage up to 120V, the modules in series go to inverter sting as usual.
The only difference is the communication signaling cables connect the BFS-11 in series and go to the button switch completes the RSD solution.
- A complete RSD solution:
- Automatic shutdown the panels when there is a temperature in the area higher than 85°C detected.
- Automatic shutdown the panels when the AC power supply loss in the button switch box.
- The fireman can manual the button switch to shutdown the panels when emergency.
