Fronius Reserva Pro battery module 3.98 kWh

The Fronius Reserva Pro DC-coupled high-voltage battery has been developed for energy-intensive applications in commercial buildings, agricultural premises and larger residential properties.

Flexibly scalable from 11.9 to 128 kWh

Thanks to its flexibly scalable capacity ranging from 11.9 to 31.9 kWh, each battery tower can accommodate between three and eight modules. Furthermore, up to four towers with the same output can be connected in parallel to achieve a total capacity of 128 kWh, thereby enabling even larger storage capacities.

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.

Maximum safety

The long-life LFP battery cells, backed by a 10-year warranty, ensure a high level of safety and prevent thermal runaway. Furthermore, the compact design of the Fronius Reserva Pro and its IP65 protection rating allow for flexible installation both indoors and outdoors.

Seamless integration

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