The Victron Energy BMS300200300 VE.Bus BMS NG is a battery management system designed specifically for Victron Lithium NG (LiFePO4) batteries in systems that include compatible Victron VE.Bus inverter/chargers or inverters. It monitors battery conditions and coordinates charging and discharging protection to help safeguard the connected Lithium NG battery bank. 

The VE.Bus BMS NG combines VE.Bus control, Bluetooth Smart connectivity, dedicated load and charge disconnect outputs, pre-alarm functionality, remote on/off control, and dedicated auxiliary power connections. Depending on battery conditions, it can disable inverting or charging through VE.Bus and coordinate compatible external loads and charging equipment through its control outputs.

Key Technology

• Designed for Victron Lithium NG Batteries
  Provides dedicated battery-management functionality for Victron Lithium NG batteries and supports properly configured 12V, 24V, and 48V battery systems.

• VE.Bus System Integration
  Interfaces with compatible Victron MultiPlus, Quattro, and VE.Bus inverter products to control charging and inverting according to battery conditions.

• Bluetooth Smart
  Integrated Bluetooth Smart enables wireless configuration, monitoring, and firmware updates through the VictronConnect app. Instant Readout provides access to key information such as state of charge, battery temperature, warnings, and alarms.

• Load Disconnect Output
  Controls the remote on/off input of compatible BatteryProtect devices, inverters, DC-DC converters, and other loads equipped with suitable remote-control functionality.

• Charge Disconnect Output
  Provides a control signal for compatible chargers and charging-control equipment when charging needs to be stopped because of battery conditions.

• Pre-Alarm Output
  Provides advance warning of an imminent cell-undervoltage condition before the Load Disconnect output is disabled, allowing a compatible LED, buzzer, or relay to provide a warning.

• Remote On/Off Control
  Remote L and Remote H terminals provide external control of the BMS. Switching the system off causes both Load Disconnect and Charge Disconnect outputs to become free-floating.

• GX Device Integration
  A compatible GX device can be connected as part of the system architecture, while the dedicated GX-Power terminal provides a power output for the GX device.

• Remote Panel Connectivity
  A compatible GX device, Digital Multi Control panel, VE.Bus Smart dongle, or supported combination can be connected through the Remote Panel interface for VE.Bus system control.

Best Uses

• Victron Lithium NG Battery Systems
  Designed for systems built around compatible Victron Lithium NG batteries requiring coordinated battery protection and equipment control.

• VE.Bus Inverter/Charger Systems
  Suitable for compatible MultiPlus, Quattro, and VE.Bus inverter installations where the BMS needs to control charging and inverting based on battery status.

• 12V, 24V & 48V Battery Banks
  Supports appropriately configured Lithium NG battery banks using series, parallel, or combined series-parallel arrangements.

• Systems with AC & DC Loads
  Provides coordinated control of compatible VE.Bus equipment and external DC loads through its VE.Bus and Load Disconnect interfaces.

• GX-Integrated Energy Systems
  Well suited for installations using a compatible GX device for system monitoring, charger coordination, and broader Victron system integration.
