Fronius Reserva Pro BMS Control Unit + Base 4,240,391 with Integrated BMS
The Fronius Reserva Pro BMS (code 4,240,391) is the battery management module of the Fronius Reserva Pro high voltage storage system and is supplied with the floor support base. The Reserva Pro battery modules of 3.98 kWh usable (70.84 V nominal) are stacked on the base; the BMS manages the protections against overcharge and deep discharge, the balancing and the communication with the inverter.
A Reserva Pro tower can count from 3 to 8 modules, covering the sizes from Pro 12.0 (11.9 kWh) to Pro 32.0 (31.9 kWh), with a maximum output current of 50 A limited by the inverter. It is possible to connect up to 4 batteries in parallel, for a scalability up to approximately 128 kWh. The system is compatible with the Fronius Primo GEN24 Plus, Symo GEN24 Plus and Verto Plus inverters, uses LFP cells produced in Europe, communicates in Modbus RS485 and is IP65 certified.
