    Backup power variants

    With our solutions, PV system owners are well prepared for all eventualities. Everything from a single source and tailored to individual needs.

    Basic Backup Power Supply with the PV Point

    The PV Point provides an integrated basic backup power supply for the Fronius GEN24 and Fronius GEN24 Plus. During a power failure, single-phase electrical loads up to 3 kW are supplied via a fused socket or a fused circuit. For even greater convenience, the PV Point Advanced takes the original PV Point to the next level by keeping selected backup loads powered by the grid, until a blackout occurs. Once a blackout happens, those loads are switched to the emergency PV Point supply, ensuring a power supply of up to 3kW from any available power from your solar or battery*.

    Advantages

    • Automatic activation in the event of grid failure
    • No complex additional installations required
    • Reliable supply for single-phase loads up to 3 kW

      * Battery not required for this solution

    Full Backup for maximum autonomy

    With the Full Backup option, the Fronius GEN24 Plus in combination with a battery storage system offers maximum independence. Our black-start capable backup power solution is not only able to keep the entire household supplied, but can also operate energy-intensive loads such as heat pumps (as long as enough power from the PV system or the storage is available). In the event of a power failure, the inverter switches to backup power mode with the help of a backup power switching device such as the automatic Fronius Backup Controller*.

    Advantages

    • Supplying the entire household including large loads
    • Switching components tailored to the customer’s requirements
    • Efficient energy flows even in a backup power situation

    How it works at a glance

    Basic backup power supply

    The PV Point is a backup power solution integrated into the inverter that supplies current to single-phase loads up to 3 kW via a fused socket or a fused circuit. Backup power management with PV Point Advanced has the advantage of having connected loads powered by the grid and switch to emergency PV Point supply when a blackout occurs.

    Full Backup

    In the event of grid failure, the hybrid inverter automatically disconnects the household from the grid. Energy for the entire household is then provided by the PV system and the battery storage system (as long as enough power is available). Our hybrid inverters and the Fronius Smart Meter ensure that the household remains disconnected from the grid until the fault is rectified and normal operation is restored.

    In order to be able to use their self-generated solar power at night, the Anzi family chose our Fronius GEN24 Plus hybrid inverter and the BYD battery storage system - together an unbeatable energy package and one of the most efficient systems on the market.
