Abstract:
Embodiments of the present disclosure describe an energy generation system including a rapid shutdown mechanism configured to prevent a flow of power from a photovoltaic (PV) array when activated, a battery pack comprising one or more power storage devices, and an inverter coupled to the rapid shutdown mechanism and the battery pack. The inverter includes anti-islanding relays configured to electrically disconnect the inverter from a utility grid when activated transfer relays configured to electrically disconnect the inverter from a load when activated, and a detection and initiation circuit coupled to the rapid shutdown mechanism, battery pack, anti-islanding relays, and transfer relays, where the detection and initiation circuit is configured to detect a triggering event and to activate the rapid shutdown mechanism, disable the battery pack, activate the anti-islanding relays, and activate the transfer relays in response to the detection of the triggering event.
