Victron VE.Bus BMS V2 Battery Management System

The Victron VE.Bus BMS V2 is the next generation of the Victron Energy Battery Management System (BMS) designed for Lithium Battery Smart batteries. These lithium iron phosphate (LiFePO4) batteries are available in 12.8V or 25.6V voltages and offer a range of capacities. The batteries can be connected in series, parallel or a combination of both, creating battery banks for system voltages of 12V, 24V or 48V. The system can contain up to 20 batteries, allowing up to 84kWh of energy storage in a 12V system and up to 102kWh in a 24V¹ and 48V¹ system.

Protection and Surveillance
BMS V2 is designed to work with Victron inverters or inverter/chargers with VE.Bus communication. It protects each individual cell in Lithium Battery Smart batteries by monitoring them for overload, undervoltage and temperature issues.
Cell voltage monitoring and balancing: The BMS communicates the battery status via two BMS cables with M8 connectors. In multi-battery systems, the BMS cables are connected in series.
Proactive alarm: Generates a warning for nearby cell undervoltage.
Load disconnection: The inverter and other loads are interrupted when a cell undervoltage occurs.

Communication and Guidance
VE.Bus communication: The BMS V2 is connected to the MultiPlus and Quattro inverters via an RJ45 UTP cable. It stops the inverter operation in case of cell undervoltage and stops charging in case of cell overvoltage or temperature problems.
Remote control: GX devices (such as Cerbo GX), Digital Multi Control panels or VE.Bus Smart dongles can be connected for remote control to control the inverter or inverter/charger cut-off mode (on/off for charger only).
