Genuine Victron long-reach communication cable
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.
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.
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.
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.
Exact part-number traceability and predictable straight-through RJ45 construction.
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.
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.
RV solar, marine power, GX monitoring, and remote equipment layouts.
Long-distance routing with exact Victron identification.
Exact part number, length, cable format, and network guidance.
Plan the 49-foot run before closing walls, floors, or bulkheads.
Complete the network with the correct cable and termination hardware.
Compatibility, long-distance routing, VE.Bus, VE.Can, terminators, and battery-CAN cabling.
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.
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.
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.
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.
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.
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.
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.
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.
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.
