Fronius Backup Controller 3PN – Full Installation & Setup Guide |Solar&Solar Wholesale PVSolar Store

In this detailed how-to video, we guide you through the installation and commissioning of the Fronius Backup Controller 3PN – the intelligent switching unit that enables seamless transition to Full Backup Mode during grid outages. When the grid fails, the Fronius Backup Controller automatically activates backup power mode, keeping your household powered via PV and battery – even if no one’s home. Once the grid is restored, it switches back to parallel operation with zero user input. Engineered for space-saving installation, the Fronius Backup Controller fits directly onto a DIN rail in the control cabinet – no need for an external switchover box, saving you time and money. The PVSolarStore and Solar&Solar Wholesale teams are always ready to support your projects with expert guidance, fast supply, and full technical backup.
