VE.Bus BMS NG

8. Appendix

In this section:

8.1. Appendix A

  1. Loads which can be controlled directly by the Load disconnect output of the VE.Bus BMS NG:

    • Inverters:

      All Inverters VE.Direct and Inverters Smart. Connect the Load disconnect output of the BMS to terminal H of the 2-pole connector of the inverter.

    • DC-DC converters:

      All Tr-type DC-DC converters with remote on/off connector, the Orion 12/24-20 and the Orion XS. Connect the Load disconnect output of the BMS to the right-hand terminal of the 2-pole connector.

    • BatteryProtect and Smart BatteryProtect:

      Connect the Load disconnect output of the BMS to terminal 2.1 (right hand terminal) for the BatteryProtect and H pin of the 2-pole connectorfor the Smart BatteryProtect.

    • Cyrix-Li-Load:

      Connect the Load disconnect output of the BMS to the control input of the Cyrix.

  2. Loads for which an inverting remote on-off cable is needed (article number ASS030550100 or -120):

    • VE.Bus inverters and VE.Bus Inverter Compact rated at 1200VA or more

  3. Solar charge controllers which can be controlled directly by the Charge disconnect output:

    • BlueSolar MPPT 150/70 and 150/80 CAN-bus:

      Connect the Charge disconnect output of the BMS to the left hand terminal of the 2-pole connector (B+).

    • SmartSolar MPPT 150/45 and higher, 250/60 and higher

      Connect the Charge disconnect output of the BMS to the right-hand terminal (marked +) or the left-hand terminal (marked H) of the 2-pole connector

  4. Solar charge controllers for which a VE.Direct non-inverting remote on-off cable is needed (article number ASS030550320):

    • BlueSolar MPPT models except the BlueSolar MPPT 150/70 and 150/80 CAN-bus

    • SmartSolar MPPT up to 150/35

  5. Battery Chargers:

    • Smart IP43 Chargers:

      Connect the Charge disconnect output of the BMS to terminal H of the 2-pole connector.

    • Other battery chargers:

      Use a Cyrix-Li-Charge.

8.2. Displaying VE.Bus BMS NG SoC on a GX Device

Unlike the VE.Bus BMS V2, the VE.Bus BMS NG transmits State of Charge (SoC) over the VE.Bus network. This guide explains how to enable and display the SoC on a GX device.

Notice

Enabling this feature adds only the SoC. No other BMS parameters are forwarded to the GX device.

Enable “Battery Monitor” on the MultiPlus/Quattro

To forward SoC to the GX device, you must enable the Battery Monitor setting on the MultiPlus/Quattro. This can be done via Remote VEConfigure or VictronConnect.

Using Remote VEConfigure

  1. Download the Remote VEConfigure file from the device

  2. Open the file in VEConfigure

  3. In the General tab, tick Battery monitor

    Notice

    "Battery capacity" and "Charge efficiency" are not relevant in this case, as these parameters are managed by the VE.Bus BMS NG.

  4. Click File → Exit and confirm saving the changes

  5. Click on 'Yes'

  6. Upload the updated file back to the MultiPlus/Quattro using Remote VEConfigure

Using VictronConnect

  1. Connect a MK3-USB interface between the MultiPlus/Quattro and the device running VictronConnect (PC or Android). Refer to the MK3-USB interface documentation.

  2. Open VictronConnect

  3. Select the MultiPlus/Quattro from My devices

  4. Navigate to Settings → General

  5. Enable the Battery monitor option

Selecting the battery monitor in the GX device

This step is only required if multiple battery monitoring devices are connected to the GX device.

In such cases, ensure that the MultiPlus/Quattro is selected as the active battery monitor:

  • Navigate to Settings → System Setup → Battery monitor and enable the option on the MultiPlus/Quattro

8.3. Powering the VE.Bus BMS NG without a connected Multi

In situations where the VE.Bus BMS NG must be operational wihtout a connected Multi, it can be powered independently.

Step-by-step

  1. Connect a DC power supply between:

    • Pin 3 (GND) of either RJ45 socket on the VE.Bus BMS NG — the sockets are internally connected, so using one is sufficient — and

    • +Bat terminal on the Phoenix 6-pin connector.

  2. Ensure correct polarity and supply voltage according to Technical specifications VE.Bus BMS NG.

  3. When powered, the VE.Bus BMS NG initialises and battery data becomes available via VictronConnect.
