Technical Specifications
The Fronius Reserva Battery Manager System (BMS) is the core control unit of the Fronius Reserva high-voltage energy storage system, designed to manage, monitor, and protect connected battery modules in photovoltaic installations. It ensures optimal charging and discharging processes while maintaining system safety and efficiency.
Built for seamless integration with Fronius hybrid inverters, the BMS enables intelligent energy flow control and supports real-time monitoring through the Fronius Solar.web platform. It plays a key role in maximizing self-consumption and improving overall system performance.
The system supports modular battery configurations, allowing flexible expansion from two to five battery modules and enabling parallel operation of multiple battery systems. Its advanced protection functions—including overvoltage, overcurrent, and thermal protection—ensure long-term reliability and safe operation of the energy storage system.
