Genuine Victron long-reach communication cable
Victron Energy RJ45 UTP Cable 15m (49.2ft) | Part # ASS030065021
A genuine Victron Energy RJ45 cable for supported VE.Bus and VE.Can communication across large RVs, boats, motorhomes, and off-grid installations.
The Victron RJ45 UTP Cable 15m, part ASS030065021, provides approximately 49.2 feet of clean, continuous routing for demanding system layouts. This 15 meter Victron cable is ideal when a MultiPlus, Quattro, compatible battery bank, or electrical equipment compartment is located far from a Cerbo GX, Ekrano GX, control panel, or central monitoring hub.

Extreme-Distance Communication Without Unnecessary Extensions
Route critical system data across large vessels, motorhomes, and off-grid installations.
Advanced power systems depend on reliable communication for monitoring, configuration, and coordinated operation. The factory 15-meter length lets installers create a continuous long-reach connection without joining several short cables through inline couplers.
The cable is useful when equipment is separated by walls, floors, bulkheads, storage bays, or machinery spaces. Correct device compatibility, termination, connector protection, and network configuration remain essential for reliable operation.
The Standard for VE.Bus & VE.Can Networks
Victron uses straight-through RJ45 UTP cables for supported VE.Bus and VE.Can products. Common applications include links between VE.Bus devices, connections to Digital Multi Control, Inverter Control or MK3-USB, and supported VE.Bus or VE.Can links to a GX device.
15 Meters (49.2 Feet) for Large Vessels & Motorhomes
Route from a rear engine room to a helm, from a fifth-wheel nose compartment into the living area, or from a remote equipment cabinet to a central monitoring display without leaving multiple joined cable segments hidden behind walls.
Genuine Quality for Professional Power-System Installations
Exact part-number traceability and predictable straight-through RJ45 construction.
High-Integrity UTP Engineering
UTP means unshielded twisted pair. The official Victron cable provides the expected straight-through construction and factory length for supported communication networks. For best results, protect the run from sharp edges, crushing, standing water, excessive heat, and unnecessary proximity to high-current wiring.
Secure, Plug-and-Play RJ45 Connectors
Pre-terminated click-lock RJ45 connectors eliminate field crimping. Secure the cable at appropriate intervals, protect the connector tabs, and leave enough service loop to disconnect equipment without pulling on the cable.
Long-reach installation applications
RV solar, marine power, GX monitoring, and remote equipment layouts.
- ✓ Route a Cerbo GX or Ekrano GX connection across a large RV, fifth wheel, motorhome, or boat.
- ✓ Connect supported VE.Bus devices such as MultiPlus or Quattro inverter/chargers across separated equipment compartments.
- ✓ Build supported VE.Can communication runs between compatible Victron products and GX devices.
- ✓ Reach from a rear engine room or machinery space to a helm, pilot house, or central monitoring panel.
- ✓ Connect equipment in an off-grid utility room to a remotely located system-control cabinet.
- ✓ Use in protected wire chases, conduits, walls, bulkheads, and electrical backboards where a continuous 15-meter run is needed.
Cable features
Long-distance routing with exact Victron identification.
Genuine Victron network cable
Factory accessory for supported Victron RJ45 communication applications.
15-meter long reach
Approximately 49.2 feet of routing distance for large mobile, marine, and off-grid layouts.
Straight-through RJ45 wiring
Pin 1 connects to pin 1, pin 2 to pin 2, and so on across all eight conductors.
VE.Bus communication support
Suitable for supported MultiPlus, Quattro, Digital Multi Control, Inverter Control, and MK3-USB communication links.
VE.Can network support
Suitable for supported VE.Can links to compatible GX devices when the network is configured and terminated correctly.
UTP construction
Unshielded twisted-pair data cable; it should not be described as a shielded Ethernet cable.
Click-lock RJ45 connectors
Pre-terminated modular plugs help create a secure connection without on-site crimping.
Continuous cable run
Avoids the extra couplers and troubleshooting points created by joining multiple shorter cables.
Installation flexibility
Useful for rear-to-front routing in fifth wheels, large motorhomes, boats, and remote equipment spaces.
Data cable only
Carries communication data; it is not a DC power cable, AC cable, or general-purpose battery interconnect.
Technical specifications
Exact part number, length, cable format, and network guidance.
Professional routing guidance
Plan the 49-foot run before closing walls, floors, or bulkheads.
- ✓ Confirm the ports, protocol, and battery-side pinout before routing the cable.
- ✓ Avoid sharp edges, crushed conduit, tight bends, hot exhaust areas, and moving mechanical parts.
- ✓ Route separately from high-current AC and DC power wiring where practical.
- ✓ Protect the cable in conduit or wire loom when it passes through exposed or high-abrasion areas.
- ✓ Label both ends and test the network before closing inaccessible panels.
- ✓ Install VE.Can terminators only where the VE.Can network design requires them.

Frequently asked questions
Victron RJ45 UTP Cable 15m FAQs
Compatibility, long-distance routing, VE.Bus, VE.Can, terminators, and battery-CAN cabling.
What is the Victron ASS030065021 RJ45 cable used for?
This genuine Victron Energy RJ45 cable carries communication data between supported Victron components over a long run. Typical uses include linking VE.Bus devices such as MultiPlus or Quattro inverter/chargers, connecting supported VE.Bus or VE.Can equipment to a GX device, and extending communication across a large RV, vessel, or off-grid installation.
How long is a 15-meter cable in feet?
Fifteen meters is approximately 49.2 feet. The long reach is useful for routing from a rear engine room, fifth-wheel storage bay, motorhome basement, or remote electrical cabinet to a Cerbo GX, Ekrano GX, control panel, or other compatible device mounted elsewhere.
Will I experience signal loss or data dropouts over a 49-foot run?
This is an official 15-meter Victron cable offered for supported RJ45 communication applications. Reliable operation still depends on correct device compatibility, proper network configuration, secure connectors, correct termination where required, and installation that avoids crushing, sharp bends, damaged plugs, and unnecessary couplers.
Can I use this to connect an Epoch battery to a Victron Cerbo GX?
Only when the documentation for the exact Epoch battery model specifies a straight-through RJ45 UTP connection. Some CAN-bus batteries require a Victron Type A, Type B, or manufacturer-specific CAN-BMS cable because the battery-side RJ45 pinout can differ. Matching connector shape alone does not guarantee compatibility.
Is this a straight-through or crossover cable?
It is a standard straight-through RJ45 UTP cable. Each conductor connects to the same pin number at both ends, which is the cable format Victron uses for supported VE.Bus and VE.Can products.
Do I need terminators when using this cable for VE.Can?
Yes, a VE.Can network normally requires a VE.Can terminator at each open end of the network. Do not install VE.Can terminators in unused VE.Bus ports; VE.Bus and VE.Can use different network rules even though both may use RJ45 connectors.
Can I use this cable for VE.Direct equipment?
No. VE.Direct uses a smaller proprietary four-pin connector and a different cable. This RJ45 UTP cable is intended for supported VE.Bus and VE.Can applications, not VE.Direct ports on SmartShunts, smaller MPPT controllers, or other VE.Direct products.
Can I use a standard 50-foot Ethernet cable instead?
A correctly wired, good-quality straight-through RJ45 UTP cable can work in supported Victron applications. The genuine Victron ASS030065021 provides exact part-number verification, predictable construction, and a factory 15-meter length. Avoid unknown pinouts, damaged modular plugs, stranded extension couplers, and low-quality cables in critical power-system communications.
Can I connect multiple 15-meter cables together for a longer run?
A single continuous cable is preferred whenever possible. Couplers add connection points that can loosen, corrode, or complicate troubleshooting. For longer requirements, verify the supported network length and choose an appropriate factory cable or system layout rather than adding unnecessary inline adapters.
