Fronius Reserva BMS + Base – The intelligent heart of your Fronius energy storage solution
The Fronius Reserva BMS (Battery Management System) with base is the central control unit for the modular Fronius Reserva high-voltage storage system. It handles communication between the battery modules and the hybrid Fronius inverter, ensuring safe, efficient and reliable operation of the storage solution.
As the basis of every Fronius Reserva storage system, the BMS provides monitoring, control and protection of the entire system. In combination with the robust base, it provides the basis for easy and space-saving installation of the storage modules.
Benefits of the Fronius Reserva BMS+ connection:
- Intelligent system control: the BMS communicates directly with the inverter and battery modules and controls all relevant charging and discharging processes.
- High safety: Thanks to integrated protection mechanisms, the battery is reliably monitored, including temperature, voltage and current.
- Modular and flexible: the system is scalable – from 6.3 to 15.8 kWh – and allows the installation of 2 to 5 storage modules per unit.
- Compact design: The base serves as a stable base for vertical installation and allows for space-saving integration even when mounted on the wall.
- Compatible & future-proof: optimally matched to all Fronius hybrid inverters (except Symo Hybrid) and prepared for modern energy solutions with emergency power options.
