The Fronius Backup Controller is a switching unit that enables an automatic transition to full backup mode. In the event of a power failure, it automatically switches to emergency power mode and back to parallel grid operation as soon as the grid is available. This solution ensures that the entire household always has a reliable power supply, even when nobody is at home.
As a space-saving solution, the Fronius Backup Controller can be installed quickly and easily on a top-hat rail in the control cabinet. This minimises installation work and costs, as an additional switch box is no longer required.
