The Fronius Reserva PRO BMS is the control unit for the high-voltage Reserva PRO battery system. It monitors the operation of the connected battery modules and manages communication between the battery and the inverter.

The BMS communicates with compatible Fronius inverters via CAN or Modbus RS485, and with the battery modules via ISO-SPI. It does not store energy independently; the complete system also requires Reserva PRO battery modules and a base unit.

A system can be configured with 3–8 battery modules, providing a usable capacity between 11.9 and 31.9 kWh. The Reserva PRO can be used with Fronius Primo GEN24 Plus, Symo GEN24 Plus, and Verto Plus inverters.
