Transfer Time

The act of a power system continuing to operate and supply power to a local area after the surrounding utility grid has disconnected. In residential microgrids, intentional islanding is the core resilience feature — when the utility grid fails, the system islands automatically and continues powering the property. Anti-islanding is a safety requirement in grid-tied systems: inverters must detect grid failure and disconnect from the utility to prevent backfeeding live power onto de-energized utility lines, protecting utility workers. Microgrid-grade systems handle both: safe disconnection from the grid and immediate transition to island operation.

On-site electrochemical energy storage that allows a property to store electricity and discharge it on demand. In a microgrid, storage may support backup operation, energy buffering, and reduced generator runtime. Transfer behavior depends on the selected equipment, system design, and operating conditions. Storage is sized in kWh for energy capacity and kW for power output; both metrics affect supported loads and duration.
