On-Grid

When a Powershare compatible vehicle is plugged in to the Universal Wall Connector, the vehicle will charge during normal day-to-day operation.

Grid Outage

In the event of a utility grid outage, the Powershare system islanding controller will detect the loss of power and automatically open the islanding contactor (in the Powershare Gateway (or Backup Switch if present)), disconnecting the home's electrical system from the grid.

After the islanding contactor disconnects from the grid, the Powershare compatible vehicle begins supplying power to the home. A brief period without power is expected during the transition.

Grid Return

When the utility power comes back on, the Powershare system islanding controller detects the return of power and begins process to verify that the system is ready to return to normal operation.

The vehicle stops supplying power before the islanding contactor reconnects the system to the grid. A brief period without power is expected during the transition.
