Fronius Reserva compatibility - Storage solutions for installers

What is the Fronius Reserva?

The Fronius Reserva is a modern high-voltage battery storage system that has been specially developed for Fronius' own hybrid inverters. It impresses with its high efficiency, simple installation and maximum safety - ideal for installers who rely on Fronius Reserva compatibility.

Which inverters is the Fronius Reserva compatible with?

The storage system can be combined exclusively with Fronius hybrid inverters:
  • Fronius Primo GEN24 Plus
    → compatible with Reserva 6.3 kWh and 9.5 kWh
  • Fronius Symo GEN24 Plus
    → full support up to 15.8 kWh
  • Fronius Verto Plus
    → compatible with all storage sizes

❌ Not compatible: Symo Hybrid or inverters from other manufacturers such as GoodWe, Huawei or SolarEdge.

👉 Tip: Always use the latest GEN24 firmware to ensure smooth communication between the storage system and inverter.

Sizing the Fronius Reserva correctly

Dimensioning is crucial for efficiency and service life:
  • Reserva 6.3 / 9.5 kWh → for single-family homes with approx. 3,500-5,000 kWh annual consumption
  • Reserva 12.6 kWh → for households with heat pump or e-mobility
  • Reserva 15.8 kWh → for small commercial applications or apartment buildings

Installer tip: Do not design the storage system too large - a high cycle utilization improves efficiency and service life.
In addition, the storage system can always be expanded with the Fronius Reserva 3.15 kWh battery storage system if required, so that the available capacity can also be adapted to increasing demand.
