The VE.Can to CAN-bus BMS Type B Cable connects Victron devices fitted with a VE.Can port to compatible CAN-bus BMS battery management systems using the Type B protocol. At 5 metres long, it gives installers room to route between a battery bank and a GX device or inverter/charger mounted at a distance.

Key features

• Connects VE.Can-equipped Victron devices to CAN-bus BMS batteries using the Type B communication protocol
• 5 metre length for installations where the BMS and inverter or MPPT sit apart
• Pre-terminated with the correct connectors at each end, no crimping required
• Victron SKU ASS030720150, compatible with the VE.Can interface on Victron MultiPlus-II GX, Quattro, Cerbo GX and other GX-series devices
• Weighs 0.22 kg

Product overview

CAN-bus communication between a battery BMS and an inverter/charger or GX device lets the BMS pass real time data: state of charge, cell voltages, charge and discharge limits, and alarm states. The system can then respond to actual battery conditions instead of fixed charge settings. The Type B variant is needed for BMS units wired to the CAN-bus Type B pinout, which differs from Type A. Fitting the wrong type means no communication, so check the BMS manufacturer's CAN-bus type before ordering.

This 5 m option is the longer of Victron's standard lengths for this cable and suits systems where the battery bank and the GX device or inverter are in separate locations. CAN-bus uses differential signalling and tolerates runs of this length where the bus is terminated correctly at both ends.

Applications

• Connecting a Cerbo GX or GX-series device to a CAN-bus Type B BMS battery system
• Linking a MultiPlus-II GX or Quattro GX to a compatible third-party lithium battery using CAN-bus Type B
• Off-grid and hybrid solar installations where the BMS and inverter/charger sit apart
• Marine and vehicle installations needing a longer run between BMS and Victron control device
• Battery cabinet builds where routing adds to the required cable length

What's in the box

• 1 x VE.Can to CAN-bus BMS Type B Cable, 5 m

Installation notes

Confirm your BMS uses the CAN-bus Type B pinout before fitting. A Type B cable on a Type A port will not communicate and may cause issues depending on the hardware. CAN-bus networks need correct termination at both ends, so check your BMS and Victron documentation for your system's topology. Installation on a solar PV or battery storage system should be carried out by a qualified electrician or accredited installer familiar with Victron equipment.
