Genuine Victron VE.Direct data connection
The standard mid-length Victron Energy data cable for clean connections between compatible battery monitors, MPPTs, chargers, inverters, and GX devices.
The Victron VE.Direct cable 1.8m, part ASS030530218, provides approximately 5.9 feet of factory-terminated reach for RV, marine, solar, and off-grid electrical systems. Use this genuine Victron Energy 1.8m VE.Direct cable to connect compatible four-pin VE.Direct devices across a standard electrical bay without cutting, splicing, or confusing it with an RJ45 VE.Bus or VE.Can cable.
Carry battery, charging, solar-yield, and device-status data between compatible VE.Direct components.
A connected Victron system depends on choosing the correct communication interface. This genuine 6ft VE.Direct cable provides a practical length for a SmartShunt, BMV battery monitor, MPPT charge controller, charger, or selected inverter installed near a Cerbo GX, Ekrano GX, or another supported monitoring device.
VE.Direct is its own four-pin data interface. This cable is not an RJ45 Ethernet cable, VE.Bus cable, VE.Can cable, direct battery CAN-BMS harness, USB interface, or high-current power lead.
Compatible VE.Direct products can include SmartShunts, BMV monitors, BlueSolar or SmartSolar MPPTs, Orion XS units, Smart IP43 chargers, selected VE.Direct inverters, and GX devices with an available VE.Direct port. Verify the exact product manual because not every Victron device uses this interface.
The standard mid-length reach works well for components mounted on adjacent panels, separate shelves, or opposite sides of the same electrical bay. It provides more flexibility than a short jumper without leaving the excess coil associated with a long cable.
Factory-made connectors help avoid improvised splices and hard-to-diagnose intermittent communication problems.
VE.Direct uses a special four-core data cable and keyed Victron connectors. Align each plug carefully, never force it into another port family, and support the cable near each product so vibration and cable weight do not stress the device port.
Victron identifies VE.Direct as an unshielded and untwisted data cable. The 1.8m run is well below the supported 10m limit, but installers should still separate it from high-current DC cables, inverter AC wiring, motors, transformers, ignition wiring, and strong RF sources where practical.
Standard-range communication links for RV, marine, solar, and off-grid systems.
Exact part-number matching for clean professional electrical-board installations.
Exact identification, physical details, interface compatibility, and installation guidance.
Choose the correct length and interface family instead of cutting or adapting the cable.
Protect the connectors, provide strain relief, and do not splice the cable.
Route the cable through protected spaces with smooth bends, secure it at sensible intervals, and avoid pinch points, sharp edges, hot surfaces, and standing water. Keep separation from high-energy conductors where practical. VE.Direct cables cannot be extended; select a longer factory cable when additional reach is required.
Common questions about ports, compatibility, length, routing, extensions, and managed-battery communication.
VE.Direct uses Victron's small four-pin connector and is used by compatible battery monitors, MPPT solar chargers, Orion XS units, Smart IP43 chargers, and selected inverters. VE.Bus and VE.Can use wider RJ45-style network ports. MultiPlus and Quattro products normally use VE.Bus, while managed lithium batteries generally use VE.Can or BMS-Can.
No. Epoch batteries with native Victron communication use CANbus rather than VE.Direct. The required connection can be a standard RJ45 UTP cable, a Victron Type A or Type B CAN-BMS cable, or a manufacturer-specific harness depending on the exact battery model and pinout. Follow the battery's communication manual.
1.8 meters is approximately 5.9 feet, commonly described as a 6-foot cable. It is a practical mid-length choice for components mounted in the same electrical bay, on adjacent panels, or on nearby shelves without a large coil of unused cable.
It can connect compatible products that have VE.Direct ports, including many SmartShunts, BMV battery monitors, BlueSolar or SmartSolar MPPT charge controllers, Orion XS units, Smart IP43 chargers, selected VE.Direct inverters, and GX devices with an available VE.Direct port. Verify both product manuals before ordering.
Victron states that direct VE.Direct cables cannot be extended and supports a maximum direct run of 10 meters. Do not cut or splice this cable. Choose a factory 3m, 5m, or 10m version when more reach is required; for distances beyond 10 meters, use a VE.Direct-to-USB interface with an active USB extension.
The standard straight VE.Direct cable is not intended to be directional. Either end can be used at either compatible VE.Direct port. Align the keyed connector carefully, push it in without forcing it, and provide strain relief near both devices.
No. It is a special four-core VE.Direct data cable with Victron's smaller four-pin connectors. It will not fit RJ45 Ethernet, VE.Bus, VE.Can, or BMS-Can sockets and is not a substitute for those cable families.
The cable itself is a data connection and does not provide electrical protection or carry charging current. It can transport monitoring or control data between compatible products, but charging safety still depends on correct device settings, battery BMS limits, wiring, fusing, and system configuration.
Secure the cable with gentle bends and strain relief, protect it from abrasion, and keep it separated from high-current battery cables, inverter AC wiring, ignition systems, motors, transformers, and radio-frequency sources where practical. VE.Direct is unshielded and untwisted, so careful routing helps reduce interference risk.
Victron currently provides a standard five-year limited warranty for its power-product range, subject to its warranty policy, proof-of-purchase requirements, and support through the original dealer.
