Fronius Reserva LFP Battery Pack 9.47kWh

Fronius Reserva 9.47 kWh High-Voltage LFP Battery for Fronius Solar Systems

Are you looking for an efficient, safe, and seamlessly integrated energy storage solution for your Fronius inverter? Fronius Reserva 9.5 is a high-voltage lithium iron phosphate (LFP) battery that offers 9.47 kWh of usable capacity. It is specifically designed for Fronius Symo GEN24 Plus and Verto Plus hybrid inverters, where high efficiency, minimal losses, and reliable backup power are valued.

Why choose Fronius Reserva 9.5?

•  DC-coupled high efficiency — Direct DC connection to the inverter minimizes conversion losses (battery efficiency up to 95%). This means more of your own solar energy for use and a lower electricity bill.

•  Safe LFP technology (pouch cells) — Cobalt-free, excellent chemical stability, and high safety. No risk of thermal runaway.

•  Long service life — More than 6000 charge-discharge cycles (60% SOH @ 25 °C). Expected lifespan of up to 10–15 years in active home use.

•  Modular and easily expandable — Tower structure consisting of three modules. You can expand from one tower (6.3–15.8 kWh) to up to four parallel towers (max. approx. 63 kWh) without additional combiner boxes.

•  Excellent backup power capability — Supports PV Point, PV Point Advanced, and Full Backup functions (depending on the inverter). The battery also operates during a power outage and allows power restoration.

•  IP65 protection — Excellent water and dust resistance. Suitable for both indoor and sheltered outdoor installation (-20…+55 °C). However, installation in a sheltered area is recommended.

•  Slim and space-saving design — Only 176 mm deep, 772 mm wide. Suitable for confined spaces like garages.

•  Smart monitoring — Integrated BMS, RS485 communication, and status display on the battery. Full compatibility with the Fronius Solar.web application for real-time monitoring.
