Fronius Backup Controller 3PN-35A
The Fronius Backup Controller is a stationary switching unit that enables automatic transition to full backup mode and is designed for use in public grids with TN-C-S/TN-S systems. Its main function is to automatically and safely disconnect all connected loads and generators from the public grid in the event of a grid failure or disruption, in accordance with the grid operator's specifications. This solution ensures that the entire household is always reliably supplied with energy as long as sufficient energy is available from the PV system or storage system – even when no one is at home. As soon as grid stability is restored, the consumers and generators are automatically reconnected to the public grid.
Features:
- Automatic solution for maximum safety
- 3- and 4-pole versions
- Auto return to normal operation
- Cable- and space-saving installation on a DIN rail in the control cabinet
