Basic Installation; Minimal Ve.bus Firmware - Victron energy VE.Bus BMS V2 Product Manual

3.2. Basic installation

1. Connect the battery BMS cables to the BMS. For multiple batteries, see the
2. Connect the inverter/charger or inverter positive and negative cables to the battery. Make sure it has been updated to the
most recent firmware version. For more information, see the
3. Connect the battery positive via the red power cable with the fuse to the BMS "Battery+" terminal.
4. Connect the VE.Bus port of the Inverter/charger or inverter to the "MultiPlus/Quattro" port of the BMS via an RJ45 cable (not
included).
5. In case of a non-new style MultiPlus 12/1600/70 and MultiPlus
mains detector. For more information, see the
Note that the BMS does not have a battery negative connection. This is because the BMS obtains battery
negative from the VE.Bus. As such, the BMS cannot be used without a VE.Bus Inverter/charger or a VE.Bus
inverter.

3.2.1. Minimal VE.Bus firmware

Before connecting the BMS to the system, the VE.Bus firmware of all inverter/chargers or inverters used in the system needs to
be updated to the latest firmware version (version xxxx489 or above).
If the inverter/charger firmware is between version xxxx415 and xxxx489, the "VE.Bus BMS" or "ESS" assistant must be installed
in the inverter/charger.
If the inverter/chargers or inverters have a VE.Bus firmware version below xxxx415, the BMS will generate a VE.Bus error 15
(VE.Bus combination error). This error indicates that the VE.Bus products or firmware versions cannot be combined. If it is not
possible to update the inverter/chargers or inverters to a VE.Bus firmware version xxxx415 or higher the VE.Bus BMS V2 cannot
be used.
