Description
Fronius Reserva BMS 4,240,371 with base is the control and mechanical foundation for one modular Reserva high-voltage battery tower. It monitors the modules, communicates with the inverter and provides the bottom support. It contains no battery cells and stores no energy. A working tower requires two to five separately purchased matching Reserva modules, a compatible Fronius hybrid inverter, project protection, cabling and professional commissioning.

Battery management and compatibility
The BMS calculates state of charge, monitors overvoltage, undervoltage, overcurrent, temperature and cell or hardware faults, provides dark-start support, exchanges operating data over RS485 and receives battery firmware updates through the inverter interface. The current Fronius compatibility table covers suitable Primo GEN24 Plus, Symo GEN24 Plus and Verto Plus variants; Fronius Symo Hybrid is excluded. Up to four equal-capacity towers may be operated in parallel, subject to the current design rules.
