Extra-long Victron system networking

Victron RJ45 UTP Cable 20m (65ft) | Part # ASS030065031

Route reliable Victron communications across large RVs, marine vessels, equipment rooms, and off-grid properties with one genuine, factory-terminated 20-meter cable.

The Victron RJ45 UTP cable 20m is the exact ASS030065031 accessory for long-run VE.Bus and supported VE.Can connections. At approximately 65.6 feet, this genuine Victron Energy cable gives installers the reach to connect equipment located in separate bays, cabins, engine rooms, control panels, or utility spaces without adding intermediate couplers or improvised extensions.

Extra-Long Reach for Large-Scale Builds

Connect equipment across a large RV, boat, workshop, or off-grid property without piecing together shorter network cords.

20 Meters (65.6 Feet) of Coverage

The extended length supports routes from a lower equipment bay to an interior control cabinet, from a marine engine room to a helm station, or from a detached inverter room to a nearby monitoring location. Measure the complete routed path—including service loops and bends—before ordering.

One Factory-Terminated Long Run

A single 20m cable can simplify troubleshooting and cable management by reducing the need for inline couplers, field crimps, or multiple patch leads hidden behind walls and bulkheads.

Built for VE.Bus & Supported VE.Can Networks

Use the correct network, port, pinout, and termination for every connected device.

VE.Bus Communication Cable

Use for supported connections involving Digital Multi Control, Inverter Control, the MK3-USB interface, multiple VE.Bus devices, and a GX device. This is a common long-run choice when a MultiPlus or Quattro installation is located away from the monitoring panel.

VE.Can Network Cable

Use for supported VE.Can links to a Cerbo GX, Ekrano GX, or other compatible GX device. A VE.Can daisy-chain requires proper termination at both open ends; the cable length does not eliminate that requirement.

Managed Battery Compatibility Check

Do not connect an Epoch or third-party battery to a GX device based only on matching RJ45 sockets. Some managed batteries use a standard straight-through cable, while others require a specially pinned CAN-bus BMS cable or manufacturer-supplied harness. Follow the exact battery manual.

Genuine Victron Energy Quality

Straight-Through UTP Construction

The cable uses RJ45 unshielded twisted-pair construction with a straight-through pinout. A crossover cable must not be substituted for Victron VE.Bus or VE.Can communication.

Keep the Factory-Terminated Ends

For dependable troubleshooting and support, retain the factory connectors whenever possible. Poor field crimps can create intermittent faults that are difficult to diagnose, especially when the cable is hidden inside a finished RV or vessel.

Long-Run Installation Applications

Large RV and motorhome systemsRoute from a rear or lower electrical bay to a forward control cabinet or living-area GX display.

Marine engine room to helmCarry supported VE.Bus or VE.Can communications through bulkheads to a protected navigation or monitoring station.

Off-grid cabin and utility roomConnect equipment installed in a dedicated power room or nearby solar shed to a conveniently located GX device.

Commercial and custom buildsSupport documented cable routes across larger mobile, workshop, and energy-storage installations.

Routing & Installation Best Practices

Confirm that both devices use a compatible VE.Bus or VE.Can connection before plugging in the cable.
Keep the data run separated from high-current DC conductors and 120V/230V AC wiring where practical; if paths must cross, cross at approximately 90 degrees.
Avoid sharp bends, crushing, excessive pulling force, unprotected metal edges, and locations where water can collect.
Protect wall, floor, and bulkhead penetrations with suitable grommets or conduit.
Leave a modest service loop at each device without tightly coiling large amounts of excess cable around high-power equipment.
Use the required VE.Can terminators at the two open ends of a VE.Can network. Do not add VE.Can terminators to a VE.Bus connection.
Label both ends with the network and destination before closing walls or panels.

Frequently asked questions

Victron RJ45 UTP Cable 20m FAQs

What is the Victron ASS030065031 RJ45 cable used for?

This genuine Victron Energy cable carries communication data between supported Victron components. Common uses include VE.Bus links between compatible MultiPlus or Quattro inverter/chargers, connections to Digital Multi Control, Inverter Control, or MK3-USB interfaces, and supported VE.Can device-to-GX connections.

How long is a 20-meter Victron cable?

Twenty meters equals approximately 65.6 feet or 787.4 inches. This extra-long reach is useful when a battery bank, inverter/charger, or networked device is installed in an engine room, basement bay, utility room, or solar shed while the GX device or control panel is mounted much farther away.

Is 20 meters too long for a Victron data cable?

No. Twenty meters is an official Victron-manufactured length for this RJ45 UTP cable family. Reliable operation still depends on using the correct ports and network type, keeping the straight-through factory connectors intact, securing the cable properly, applying the required VE.Can termination, and following the routing guidance in the connected-device manuals.

Can I run this 20m cable next to 120V or 230V AC wiring?

Keep communication wiring separated from AC conductors and high-current DC cables where practical, especially over a long parallel route. If the paths must cross, cross them at approximately 90 degrees, protect the cable from sharp edges, and follow applicable electrical and marine installation standards.

Can I use this cable to connect an Epoch battery to a Cerbo GX?

Only when the documentation for that exact Epoch battery and Victron system specifies a standard straight-through RJ45 UTP cable. Some managed-battery integrations require a specially pinned VE.Can-to-CAN-bus BMS cable or an Epoch-supplied communication harness. Never connect the devices solely because both ports use an RJ45 connector.

What is the difference between VE.Bus, VE.Can, and VE.Direct?

VE.Bus is commonly used by compatible Victron inverter/chargers and related control devices. VE.Can is a CAN-bus network used by compatible GX devices and supported CAN products, and it requires termination at the two open ends. VE.Direct uses a smaller proprietary connector and requires a VE.Direct cable, so this RJ45 cable is not a substitute for VE.Direct wiring.

Can I cut this cable and crimp a new RJ45 connector?

Cutting and re-terminating the cable is not recommended. Poor RJ45 crimps are a common source of intermittent communication faults that can be difficult to diagnose. For the most supportable installation, retain the factory-terminated cable and manage any excess length with a protected service loop.

Do I still need VE.Can terminators with a 20-meter cable?

Yes. Cable length does not replace network termination. A VE.Can daisy chain needs a terminator at each open end. VE.Bus connections do not use VE.Can terminators, so first confirm which network and ports you are installing.

Is this a straight-through or crossover RJ45 cable?

It is a straight-through RJ45 UTP cable. Do not substitute a crossover cable, because crossover wiring is not suitable for Victron VE.Bus or VE.Can equipment.

Compatibility and installation note

Confirm the exact port type, network profile, cable pinout, termination method, and device-manufacturer instructions before installation. RJ45 describes the connector shape—not universal electrical compatibility. This cable carries communication data and does not replace required battery power cabling, fuses, breakers, or system protection.
