Victron GX

Most Victron devices can be controlled via a GX, for example the CCGX and Cerbo GX. The GX sends the correct info to the charger/inverter, for example to the Quattro.

Some devices even have a GX integrated, for example the Multiplus GX. This saves on adding an external GX.

By combining a 123\SmartBMS with the Victron GX, it is possible to control the connected Victron devices by the 123\SmartBMS.

In any case, always add an energy efficient power relay to the 123\SmartBMS signal relay(s). This ensures that the BMS is able to disconnect all connected loads/chargers in case of an emergency, thus protecting the batteries at all times.

Setup the Victron device with VEConfig

If your device is not configured for control by the GX, then make sure to do this.

The following step describes the configuration of a Phoenix/Multiplus/Quattro with VEConfig.

Step 1. Use the MK3-USB and connect it to the Victron device. Download and install Victron VEConfig.

Step 2. Add the ESS Assistant

Step 3. Start the assistant. Select “Other BMS”.

Continue until the assistant is finished.

Step 4. Send the settings to the target.

Connect the 123\SmartBMS to the Victron GX.

Step 1. Download and install the 123\SmartBMS made “venus-data.tar.gz” software which can be found here. Put it on an empty FAT32 formatted USB drive. Do not extract the file.

Step 2. Plug the USB drive into a Victron GX USB data port.

Step 3. Reboot the GX. The software is now copied. After the GX is restarted, you can remove the USB drive.

Step 4. Reboot again. The software will install after the reboot.

Step 5. Connect a 123\SmartBMS to USB cable from the 123\SmartBMS End Board Ext Data port to the Victron GX USB port. After several minutes, you should see a 123\SmartBMS instance appear on the remote console and VRM.

Note: if you have the Victron Cerbo GX, only two out of three USB ports work – the data ports

Enable DVCC on the Victron GX

Open the Victron GX remote console, either via LAN or via VRM. Go to Settings->DVCC. Enable DVCC.

Also enable SVS and STS. This ensures that the BMS measured voltage and temperature are used by the Victron system.
