The Victron CANUSB interface is a CAN bus to USB converter for Victron Energy systems. It lets a PC or laptop talk directly to devices on a CAN bus network, for configuration, monitoring and diagnostics without needing a dedicated GX device. It suits installers and engineers who need direct CAN bus access during commissioning or fault-finding.

Key features

• Converts CAN bus signals to USB for direct PC connectivity
• Works with Victron Energy CAN bus networks used across inverter, battery and BMS installations
• Weighs 0.06 kg, suited to use as a portable diagnostic tool
• Connects via a standard USB port, no specialist hardware needed beyond a PC or laptop
• Bus-powered via USB, so no separate power supply is required during use

Product overview

The CANUSB interface bridges a CAN bus network and a standard USB port on a Windows PC or laptop. CAN bus is the protocol used between many Victron devices, including certain battery management systems, inverter/chargers and third-party BMS units. Without a GX device present, direct CAN bus access is otherwise unavailable, which makes this interface a practical tool during commissioning or servicing.

It is particularly useful when connecting to battery systems that communicate via CAN bus, such as those using VE.Can or compatible third-party BMS protocols. An installer can read live data, verify communication between devices and carry out configuration directly from a laptop.

Applications

• Direct CAN bus communication between a PC and Victron CAN-enabled devices during commissioning
• Diagnostics and fault-finding on CAN bus networks in off-grid and battery storage installations
• Configuration of third-party BMS units communicating over CAN bus within a Victron system
• Monitoring and data logging from CAN bus devices where no GX device is installed

What's in the box

• 1 x Victron CANUSB interface

Installation notes

Intended for use by qualified installers and engineers familiar with CAN bus networks and Victron Energy systems. Install the correct software drivers on the PC before use. Follow appropriate electrical safety procedures when working on live battery or inverter systems. This is a diagnostic and configuration tool and should not be left permanently connected in a production installation without confirming compatibility with the system design.
