Genuine Victron communication cable
A genuine Victron Energy RJ45 cable for short, clean VE.Bus and VE.Can communication links.
The Victron RJ45 UTP Cable 0.3m, Epoch SKU ASS030064901, is a compact Victron Energy RJ45 cable built for reliable data communication between supported VE.Bus, VE.Can, control, interface, and GX components. At only 0.3 meters—approximately 11.8 inches—this 0.3 meter Victron cable is ideal for clean solar wiring boards, tightly mounted RV and marine power systems, and adjacent Victron components where excess cable creates clutter.
Reliable system data begins with the correct cable and documented pinout.
Advanced inverter, charger, monitoring, and battery systems depend on consistent communication to report status and coordinate operation. This genuine Victron RJ45 UTP cable provides a short, straight-through connection for documented Victron network applications, reducing excess cable and helping installers keep communication wiring separate, organized, and easy to service.
The cable uses the familiar RJ45 connector format, but it should only be installed in ports and systems that specifically call for a standard RJ45 UTP cable. Battery CAN connections are model-specific, and some managed batteries require a special Type A, Type B, or manufacturer-supplied communication harness instead.
Use this VE.Bus communication cable for documented MultiPlus, Quattro, control-panel, MK3-USB, and GX connections. It can also serve as a VE.Can network cable between compatible devices when their manuals specify a standard straight-through RJ45 UTP cable. VE.Can networks require the correct terminators at both ends.
At approximately 11.8 inches long, this short RJ45 cable is purpose-built for components mounted close together. It minimizes coils, makes service loops easier to control, and keeps compact solar, RV, marine, and battery-system wiring boards professional and readable.
Correct straight-through wiring and manufactured connector quality simplify troubleshooting.
UTP means Unshielded Twisted Pair. The twisted conductor pairs help preserve data integrity in supported Victron communication networks. Victron advises using manufactured cables because incorrect pinouts and poor field crimps can produce intermittent, difficult-to-diagnose communication faults.
RJ45 plugs on both ends allow quick installation into compatible ports without cutting or crimping. Confirm the port label, network type, speed, termination requirements, and device manual before powering or commissioning the system.

Common companion items for communication and system setup.
RJ45 is a connector shape—not a guarantee of identical pinout or protocol.
Identify whether the connection is VE.Bus, VE.Can, BMS-Can, CAN-bus BMS, legacy VE.Net, or a manufacturer-specific battery link. Configure the correct GX CAN profile, install terminators where required, and follow the connected equipment manuals before commissioning the system.
Common questions about part number, cable length, VE.Bus, VE.Can, Cerbo GX, and battery communication.
This 0.3-meter Victron RJ45 UTP cable is a short data and communication cable for documented Victron connections. Common uses include VE.Bus links between compatible MultiPlus or Quattro devices, connections to a GX device, Digital Multi Control or Phoenix Inverter Control connections, and an MK3-USB interface. It can also be used for standard VE.Can links when the connected device manuals call for a straight-through RJ45 UTP cable.
0.3 meters is approximately 11.8 inches, or just under 1 foot. The short length is ideal for devices mounted side by side on a compact electrical board, inside a rack, or within the same battery and inverter compartment.
A correctly wired, straight-through RJ45 UTP cable may appear physically similar, but Victron recommends manufactured cables to reduce communication problems caused by crossover wiring, poor crimps, broken conductors, or inconsistent connector quality. The genuine Victron part also makes cable identification and troubleshooting easier.
Only when the exact Epoch battery manual specifies a standard straight-through RJ45 UTP cable for that connection. Some Epoch V2 and V2-T systems use standard RJ45 cables between batteries but use a supplied grey communication harness or a model-specific CAN cable at the GX device. Other managed batteries require a Victron VE.Can-to-CAN-bus BMS Type A, Type B, or manufacturer-specific cable. Verify the battery manual before connecting it.
This product is a standard straight-through RJ45 UTP cable for the Victron applications listed by the manufacturer. Do not substitute a crossover cable, because a crossover pinout can cause communication faults or prevent connected equipment from being detected.
VE.Can networks must be terminated at both ends with the correct VE.Can terminators. VE.Bus connections are different: unused VE.Bus ports should generally remain open and should not receive blue VE.Can terminators. Follow the manual for the exact device and network type.
No. This is a low-voltage data and communication cable. It is not a battery interconnect, charger cable, AC power cable, or DC current-carrying cable. Use properly sized power conductors for all battery and inverter connections.
Epoch currently lists this product under SKU ASS030064901. Victron’s current 2026 price list identifies the 0.3-meter RJ45 UTP cable as ASS030064900. This may reflect a seller, regional, packaging, or revision suffix. If exact part-number matching is required for procurement, confirm the label with Epoch or Victron before ordering.
