The VE.Bus BMS NG is a battery management system (BMS) for Victron Energy Lithium NG Batteries (not to be confused with

the lithium smart batteries without NG). These batteries are based on Lithium Iron Phosphate (LiFePO4) batteries and are available in

12,8V, 256V and 51,, 2V in various capacit. They can be connected in series, parallel, or a combination of both to create batteryy options

banks for system voltages of 12V, 24V, or 48V. A maximum of 50 batteries can be used when configuring a bank with 12V or 24V

batteries, while up to 25 batteries can be used with 48V batteries. This allows for a maximum energy storage capacity of 192 kWh

with 12V batteries, up to 384 kWh with 24V batteries, and 128 kWh with 48V batteries. For comprehensive details about these

batteries, visit the Victron Lithium NG battery product page.

The VE.Bus BMS NG is designed to interface with and protect Victron Lithium NG batteries in systems that include a Victron VE.Bus

inverter/charger

. It relies on this connection to perform key functions such as enabling/disabling charge and discharge

based on battery conditions.

Based on the status of the Lithium NG battery, the BMS will:

•Generate a pre- alarm to indicate an imminent cell undervoltage condition

•Disable inverting in VE.Bus inverters or inverter/chargers via VE.Bus, and disconnect other loads via the Load Disconnect

terminal in case of cell undervoltage

•Disable charging in VE.Bus inverters or inverter/chargers via VE.Bus, disable VE.Direct and VE.Can solar chargers via a GX device,

and disconnect other chargers via the Charge Disconnect terminal in case of cell overvoltage, undertemperature, or

overtemperature

MultiPlus, Quattro or Inverters connect to the ‘MultiPlus/Quattro’ port with a standard

RJ45 UTP cable. The BMS disables inverting in the case of a cell under voltage condition and disables charging in the case of a

cell over voltage or temperature condition.

: : A GX device (such as a Cerbo GX), Digital Multi Control (DMC) panel or a VE.Bus Smart

dongle (including any combination) can be connected to the BMS via the 'Remote panel' port. These accessories can all be used

in combination with the BMS to remotely control the VE.Bus Inverter or inverter/charger switch state (on/off/charger- only).
