Genuine Victron long-reach communication cable
A genuine 3-meter Victron RJ45 UTP cable for clean, reliable VE.Bus and VE.Can communication across RV, marine, and off-grid equipment spaces.
The Victron RJ45 UTP Cable 3m is the official straight-through data cable listed by Epoch as part ASS030064981. At approximately 9.84 feet long, it provides the extended reach needed to connect supported Victron Energy components between separate cabinets, storage bays, solar backboards, or protected compartments—without splicing short patch cables together.
Reliable data transfer across inverter bays, battery compartments, and control cabinets.
Advanced power systems depend on uninterrupted communication between inverter/chargers, GX devices, control panels, and compatible networked equipment. This genuine Victron Energy RJ45 cable provides the standard straight-through UTP connection specified for supported VE.Bus and VE.Can links while giving installers more freedom to place equipment where it fits best.
Always match the cable to the device manual and port label. RJ45 is only the connector shape; VE.Bus, VE.Can, BMS-Can, Ethernet, and specially pinned battery communication ports are not automatically interchangeable.
Use this cable for Victron connections that explicitly call for a standard RJ45 UTP lead. Common examples include VE.Bus links between a MultiPlus, Quattro, compatible inverter, or GX device; connections to Digital Multi Control, Inverter Control, or MK3-USB interfaces; and supported VE.Can device-to-GX connections.
The 3-meter length equals approximately 9.84 feet. It provides practical reach for connecting a MultiPlus or Quattro in an inverter bay to a Cerbo GX in a nearby control cabinet, routing from an RV pass-through compartment to an interior electrical panel, or carrying supported network communication through a protected boat equipment space.
Known part number. Known straight-through wiring. Fewer troubleshooting variables.
Victron systems use a straight-through RJ45 UTP cable—not a crossover cable. A correctly manufactured third-party straight-through cable may work in supported applications, but the genuine ASS030064981 gives you a known Victron part, factory-terminated connectors, and the exact 3-meter length. That removes one major variable when diagnosing VE.Bus or VE.Can communication problems in an RV, boat, or off-grid installation.
The cable uses straight-through RJ45 UTP construction, with each pin connected to the matching pin at the opposite end. Factory termination avoids the crimping errors and intermittent faults that can occur with field-made communication cables, especially when a run is routed through panels or compartments.
Pre-terminated RJ45 connectors on both ends click into compatible ports for fast installation. Route the cable with gentle bends, protect it from sharp edges and hot surfaces, and add strain relief near equipment so vibration or service work does not pull on the connector latches.
Do not assume this standard cable is the correct Epoch Victron integration cable merely because the battery and GX device both use RJ45-style ports. Some managed batteries require a specially pinned VE.Can-to-CAN-bus BMS cable or an Epoch-supplied communication harness. Use ASS030064981 only where the battery and Victron manuals specifically call for a standard straight-through RJ45 UTP cable.
Exact part details, length conversion, and supported communication uses.
Plan the 10-foot run before closing walls, panels, or equipment covers.
Power down equipment when required by the device manuals, verify the correct VE.Bus or VE.Can port, and push each RJ45 connector fully into place until the latch engages. Route the cable through protected pathways with broad bends, keep it clear of sharp edges and high-heat surfaces, provide strain relief at both ends, and avoid bundling unnecessary excess cable tightly around high-current conductors.
Frequently asked questions
This genuine Victron Energy cable carries communication data between supported Victron components. Common uses include connecting VE.Bus inverter/chargers such as MultiPlus or Quattro units to a compatible GX device, linking Digital Multi Control or Inverter Control panels, connecting an MK3-USB interface, and making supported VE.Can device-to-GX connections.
Three meters equals approximately 118.1 inches or 9.84 feet—commonly described as a 10-foot cable. This longer length is useful for routing through RV cabinetry, protected boat compartments, or between equipment mounted in separate areas.
A properly manufactured straight-through RJ45 UTP cable can work in Victron connections that call for a standard cable, but a crossover cable cannot. The genuine Victron ASS030064981 removes uncertainty about the part number, wiring format, connector termination, and cable length. Never select a cable based only on the fact that the plug looks like Ethernet.
Only when the specific Epoch battery documentation calls for a standard straight-through RJ45 UTP cable in that position. Many managed battery-to-GX connections require a specially pinned VE.Can-to-CAN-bus BMS cable or an Epoch-supplied communication harness. Follow the exact battery manual, port labels, configuration instructions, and Victron CAN profile for your model.
It is a straight-through RJ45 UTP cable. Each pin connects to the same pin number at the opposite end. Crossover cables are not suitable for normal Victron VE.Bus or VE.Can connections.
For a standard VE.Can daisy-chain network, install the correct VE.Can terminator at each open end of the network. VE.Bus connections do not use those blue VE.Can terminators; unused VE.Bus ports should remain open. Managed battery networks may have different termination requirements, so follow the battery and GX device manuals.
