Victron Energy Integration Guide

How to connect your TITAN Lithium Battery to a Victron GX Device (Cerbo, Color Control, etc.)

Why use CANBUS?

Unlock the Full Power of Your System Connecting your TITAN Lithium battery to a Victron GX device isn't just about monitoring; it’s about total system intelligence. By establishing a data link (CAN-bus), your battery takes control of your Victron system, automatically telling the inverter and solar chargers exactly what it needs.

• 100% Accurate State of Charge (SOC): No more guessing or drift. The battery tells the system exactly how much energy is left.

• Safety First: The battery automatically manages charge currents and stops charging if it gets too cold (utilising the built-in heater) or full.

• Plug & Play: Designed to work seamlessly with Victron’s native "BMS-Can" protocol.

• Automatic Adjustments: When connecting multiple batteries in parallel, the system will automatically adjust available capacity, charge & discharge current allowances in real time

What you'll need

Before you begin, ensure you have the following components ready.

• TITAN Lithium Battery (Any model with Comms Ports).

• Victron GX Device (Cerbo GX, Color Control GX, Venus GX, Ekrano GX, or any inverter that is GX enabled).

• TITAN Comms Cable (RJ45).

  • Note: Standard ethernet cables may look the same but often lack the specific pin-out required for data transmission. Please use the certified TITAN cable - ones from Victron or other brands will not work.

How to connect

Step 1: Identify the Ports

• On the Battery: Locate the data ports on your battery (on the top for 230Ah+ or side for 105Ah-180Ah). Find the port labeled RJ45-2 & RJ45-3.

• On the Victron Device: Locate the ports labeled BMS-Can or VE.Can.

Step 2: Plug In

• Connect the labelled 'To Battery' end of the RJ45 Comms Cable into the battery's CAN port.

• Connect the labelled 'To Inverter' end into the Victron’s BMS-Can port.

  • Tip: If you are using a Cerbo GX, use the port specifically labeled "BMS-Can" (usually the middle pair). BMS-Can has been renamed on V2 Cerbos to VE.CAN

Step 3: Terminate the Network (Crucial for multiple batteries)

• If you are connecting multiple batteries, daisy-chain them together first (Battery 1 to Battery 2, etc.) using normal CATV (CAT5) ethernet cables, and plug the Victron cable into the first or last free port in the chain.

• Ensure the  Terminator (supplied with your battery) is plugged into the last remaining free port on the last battery or you can use the Victron Blue Terminator (supplied with your Victron device) plugged into the second BMS-Can port on the Victron device to close the data loop.

Victron Console Settings

Once plugged in, you need to tell the Victron device to "listen" to the battery.

1. Open your Victron Remote Console or touch screen

2. Navigate to Settings > Connectivity > VE.Can port > CAN-bus profile.
   

3. Change the profile to: CAN-bus BMS LV (500 kbit/s).

   • Note: Do NOT select "VE.Can & Lynx Ion BMS" – this is for Victron's own batteries.

Enabling DVCC (The Brain)

Distributed Voltage and Current Control (DVCC) allows the Titan battery to control the charging logic of the entire system.

1. Go to Settings > System Setup > Charge Control > DVCC.

2. Enable DVCC: Turn this ON.

3. Limit Charge Current (Optional): If you have a small battery bank but a large current charge input, you can switch this on. The BMS will control how much current is allowed through the system.

4. SVS (Shared Voltage Sense): Turn this OFF. The BMS provides the most accurate voltage reading directly.

5. STS (Shared Temperature Sense): Turn this OFF. The battery monitors its own temperature internally.

Verification

If successful, the battery should appear in your Device List.

1. Go to the main menu.

2. Look for a device named Generic BMS or Titan Lithium (depending on firmware version).

3. Click on it. You should see live stats for:

   • Voltage (V)

   • Current (A)

   • State of Charge (%)

   • Temperature (°C)

Troubleshooting:

• Don't see the battery? Check your cable type. A standard LAN cable often works for monitoring but may not allow full control. Ensure you are using the correct CANbus cable sold by TITAN.

• System Charging Too Fast? Double-check your DVCC settings and ensure "Limit Charge Current" is active if your charger exceeds the battery's recommended max charge rate (see your battery label).
