The Victron Energy VE.Bus BMS V2 (MPN: BMS300200200) is the next generation of the VE.Bus BMS for Victron Lithium Smart batteries (LFP-Smart) 12.8V and 25.6V. Each individual cell of a LiFePO4 battery must be protected against overvoltage, undervoltage and overtemperature. The VE.BUS BMS V2 takes on exactly this task. The product is suitable for protecting 12V, 24V and 48V battery banks and works in an operating voltage range of 9 - 70 VDC.
VE-BUS BMS V2 in conjunction with Victrons LiFePO4 batteries
Victron LiFePO4 batteries have built-in cell balancing, temperature and voltage control (short name: BTV). They are connected to the VE.Bus BMS V2 via two M8 round connector cable sets. The BTVs of several batteries can be chained together. They can be connected in series, parallel and both series and parallel, allowing a battery bank of 12V, 24V or 48V to be designed. Up to 20 batteries in a system are possible, resulting in a maximum energy storage of 84kWh in a 12V system and 102kWh in a 24V and 48V system. For further details, please refer to the technical documentation for our LiFePO4 battery.
Core tasks of the Victron VE.Bus BMS V2
- Specifically designed for use with Victron Lithium Battery Smart 12.8V & 25.6V batteries.
- Communicates directly with the lithium battery via the battery's M8 circular connector cables
- Shutting down or disconnecting VE.Bus inverters or inverters/chargers via VE.Bus and other loads via the "Disconnect load" terminal in the event of cell undervoltage
- Shut down or disconnect VE.Bus inverters or inverters/chargers via VE.Bus, VE.Direct and VE.Can solar chargers via a GX device and other chargers via the Charge Disconnect terminal in the event of cell overvoltage, undertemperature or overtemperature.
Difference to VE.Bus BMS
The VE.Bus BMS V2 was specifically developed for use in systems with GX devices and is therefore perfect for ESS or backup applications with a battery capacity of up to 84kWh (12V) or 102kWh (24V/48V).
The BMS V2 also has a remote contact for remote control (ON/OFF).
Communication with VE.Bus products
MultiPlus, Quattro or Phoenix inverters are connected to the “MultiPlus/Quattro” connection using a standard RJ45 UTP cable.
The BMS disables inversion in the event of cell undervoltage and charging in the event of cell overvoltage or overtemperature
Communication with devices for remote control
A GX device (e.g. Cerbo GX), Digital Multi Control (DMC) panel or VE.Bus Smart Dongle (including any combination) can be connected to the BMS via the “Remote Panel” port. This accessory can be used in combination with the BMS to remotely control the switching state of the VE.Bus inverter or inverter/charger (On/Off/Charger only)
Terminals for additional inputs and outputs
The BMS has a dedicated power output (GX-Power) for a GX device and an additional power input (Aux-In) for an external DC power source, e.g. B. a power adapter. In the event of a system shutdown, the GX device continues to be supplied with power via the auxiliary voltage input or is disconnected from the mains to prevent further battery discharge
