Fronius Reserva battery module 3.15 kWh

Maximum efficiency, maximum independence

The Fronius Reserva DC-coupled high-voltage battery enables the efficient storage and use of solar energy thanks to minimal conversion losses. Furthermore, the battery offers enhanced safety thanks to its long-lasting lithium iron phosphate technology, which is resistant to overheating and short circuits.

Maximum adaptability from 6.3 to 63 kWh

Thanks to the flexibly scalable capacity ranging from 6.3 to 15.8 kWh, each battery tower can accommodate between two and five modules. Furthermore, up to four towers can be connected in parallel without the need for additional accessories, achieving a total capacity of around 63 kWh – meaning that even larger storage capacities are possible, depending on customer requirements.

The integrated status display also allows the charge level or battery status to be viewed directly on the unit.

Emergency power capability

With the Fronius Backup Controller or Backup Switch, you can switch to full backup emergency power mode either manually or automatically. These cost-effective switching components can be installed in the control cabinet to save space and eliminate the need for additional hardware, such as switch boxes.

10-year performance guarantee

Fronius guarantees that, after 10 years, at least 80 per cent of the Reserva’s battery capacity will still be usable.

Slim, space-saving design

Thanks to its slim design, the storage unit can be installed in confined spaces such as garages, whilst its robust construction allows for ambient temperatures ranging from -20 to +55 °C. Furthermore, its IP65 protection rating enables flexible installation both indoors and in sheltered outdoor areas.

Seamless integration

Optimally matched to Fronius hybrid inverters, it integrates seamlessly into your customers’ photovoltaic systems.
