Further Information From The Manufacturer

Converting solar energy, controlling, distributing and using solar energy – and now also storing solar energy: With the Fronius Reserva, the Austrian provider of solar electronics completes its product portfolio.

The Fronius Reserva is a high-voltage battery with DC coupling that guarantees almost loss-free charging and discharging performance. The storage modules are stacked on top of each other like building blocks as a plug-and-play connection without the need for cabling. The new battery storage system is optimally matched to the two hybrid inverters Fronius GEN24 Plus and Fronius Verto Plus and can therefore be seamlessly integrated into an existing photovoltaic system. The tried-andtested Solar.web app is all that is needed for visualization; no additional software is required. The Fronius Reserva status display also shows the current charge status and indicates if there is a fault.

Bundle Includes:

• 4 x Fronius 3.15kWh Reserva Module AUS-NZ
• 1 x Fronius Reserva BMS AUS-NZ
