Fronius

The Fronius Reserva is a highly efficient, DC-coupled high-voltage battery designed to store solar energy with minimal losses. It is the perfect complement to Fronius hybrid inverters such as the GEN24 Plus, delivering maximum independence and performance.

The battery is based on safe and durable lithium iron phosphate (LFP) technology. Thanks to its modular design, the capacity can be flexibly adapted to your needs by combining two to five battery modules into a tower. For even greater demands, up to four battery towers can be connected in parallel.

With an IP65 protection rating, the Fronius Reserva is resistant to dust and water and is suitable for installation both indoors and in protected outdoor areas. European data security and fast service ensure maximum reliability and worry-free use.

Special Features

Flexibly expandable

The Fronius Reserva can be flexibly adapted to your energy needs. A battery tower can be equipped with two to five modules, enabling a usable capacity ranging from 6.31 kWh to 15.79 kWh. For even greater storage capacity, up to four identical battery towers can be operated in parallel.

High-Performance MPPT for High Yield

The lithium iron phosphate (LFP) technology used is considered one of the safest and most durable on the market. It offers high thermal stability and a long service life, which is underscored by a 10-year warranty. The IP65 protection rating also ensures reliable operation in various environments.
