Fronius Reserva Capacities
The Fronius Reserva battery storage systems are available in different capacities. The following sizes are possible per battery tower:
- 6.3 kWh – Ideal for small households with moderate energy demand.
- 9.4 kWh – For households with higher energy demand and larger PV systems.
- 12.5 kWh – Perfect for larger households or small businesses that want to store more energy.
- 15.8 kWh – For large households or businesses aiming for maximum energy independence.
Up to four battery towers can be operated in parallel. This enables a maximum storage capacity of 63.2 kWh in one system. However, this is not possible with all Fronius inverters. Here you can find the maximum tower height and number per inverter.
The maximum charging power in combination with the Fronius Symo GEN24 (regardless of the number of battery towers) is limited by the inverter to approximately its rated output. With a Fronius Symo GEN24 10.0, this is approx. 10 kW charging / discharging power.
