SYSTEM AND METHOD FOR RAPID SHUTDOWN OF SOLAR ARRAY

One variation of a system includes a hub and a module coupled to a solar array. During a first time period: the hub detects nominal operation of the solar array broadcasts a first token accordingly; and the module receives the first token, authenticates the first token; and maintains a switch—coupled to an output terminal of the module—in a closed position to output power from a solar panel to an inverter in response to authentication of the first token. During a second time period: the hub detects deviation of the solar array from nominal operation and withholds broadcast of tokens accordingly; and the module triggers the switch to transition to an open position to cease output of power from the first solar panel to the inverter in response to absence of receipt of a second token broadcast by the hub.
