Product description

The Fronius Reserva BMS (Base Module) is the control and protection unit for each Reserva battery tower. It enables the connection, monitoring, and management of battery modules (3.15 kWh each) and communicates with Fronius GEN24 Plus / Verto Plus inverters via RS485 (Modbus RTU).

The BMS module includes essential protection functions (e.g., overcharge, deep discharge, and temperature control), LED status indication, and DC connections (4× Amphenol). The system is suitable for indoor and protected outdoor installation (IP65), operates within a temperature range of −20 to +55 °C, and up to 2000 m above sea level.

Each tower configuration (Reserva 6.3 / 9.5 / 12.6 / 15.8) requires one BMS module.
