The Fronius Reserva is an efficient DC-coupled high-voltage battery for storing solar energy with minimal losses. It can be flexibly expanded with two to five modules and is perfectly matched to Fronius hybrid inverters - for maximum performance. European data security and fast service ensure maximum reliability.

The Fronius Manual Backup Switch enables manual backup for up to 63A, ideal for essential loads. DIN rail mountable for compact, integrated installation.

Surge protection device for the Fronius Tauro inverters. Type 2 and Type 1+2 versions available.

The Fronius Automatic Backup Controller enables automatic backup for up to 35A per phase, ideal for essential loads. DIN rail mountable for compact, integrated installation.

The Fronius Sensor Card can measure up to six sensors including irradiation, ambient temperature, module temperature and wind speed. All data can then be integrated into the Fronius Solar.web monitoring. Even when measuring just irradiation levels and module temperature, you can quickly identify anomalies in the system output to keep performance at a consistently high level.
