The Fronius Backup Switch is a stationary device for use in public power grids with TN/TT systems. In the event of a grid failure, all connected loads and power-generating devices can be manually disconnected from the public grid in accordance with the grid operator's specifications. The Fronius Backup Switch enables manual switching to the backup power supply. As soon as the public grid is stable again, the Fronius Backup Switch can be used to manually switch back to the power supply from the public grid. The Fronius Backup Switch is required for systems with batteries to enable manual backup power switching.
