Fronius Backup Controller 3P-35A

Fronius Backup Controller 3P-35A

Note: Suitable for 3-phase grids where neutral conductor disconnection is not required. Use is only permitted after enquiry and approval by the network operator.

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 consumers and generators from the public grid in the event of a grid outage or disturbance, in accordance with the grid operator's requirements. This solution ensures that the entire household is always safely supplied, as long as sufficient energy is available from the PV system or battery storage - even when no one is home. Once 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 variant
• Automatic return to normal operation
• Cable- and space-saving DIN rail mounting in the distribution cabinet

¹⁾The Full Backup emergency power option is not available for the Fronius Symo GEN24 3.0-5.0 Plus.
