Advanced Protection Controller for Lithium Battery-Based Energy Systems

The VE.Bus BMS NG is an intelligent battery management system engineered specifically for Victron Lithium NG batteries. It protects against cell undervoltage, overvoltage, and temperature extremes, while coordinating charge and load control across Victron inverters, chargers, and GX devices. Supporting configurations of up to 50 batteries in parallel or series, it allows scalable systems from 12V to 48V and up to 384 kWh capacity. Integrated Bluetooth enables wireless monitoring and firmware updates via the VictronConnect app, while multiple outputs provide granular control of loads, chargers, and alarms to prevent battery damage and maximise operational safety.

Key Features

• Bluetooth Smart connectivity: Enables wireless configuration, firmware updates, and real-time monitoring using the VictronConnect app.
• Load disconnect output: Controls inverters, DC-DC converters, or BatteryProtect devices, disconnecting loads when battery voltage is too low.
• Charge disconnect output: Disconnects chargers when overvoltage or temperature thresholds are exceeded, preventing battery stress or failure.
• Pre-alarm output: Activates a warning signal 30 seconds before shutdown, giving users time to respond to undervoltage conditions.
• Remote on/off terminal: Allows full control of load and charge disconnection via external switches, relays, or automation systems.
• Status LED indicators: Blue, red, and VE.Bus LEDs show Bluetooth status, errors, warnings, and overall VE.Bus activity.
• VE.Bus communication: Seamlessly integrates with MultiPlus, Quattro, and compatible inverters for coordinated charging and discharging.
• Remote device interface: Works with Cerbo GX, Digital Multi Control, and VE.Bus Smart dongle for system-wide control and monitoring.
• Compact and durable design: Lightweight ABS housing, IP20 rating, and an operating range of -20 to +50 °C ensure dependable performance.

This compact BMS ensures critical battery safety in high-performance energy systems, optimising system life and resilience.
