Victron RJ45 Splitter for VE.Bus Parallel and Three-Phase Systems

Reliable Signal Distribution for Victron MultiPlus Inverter/Chargers

The Victron RJ45 splitter is a purpose-built accessory designed to expand VE.Bus connectivity in Victron MultiPlus 500VA to 1600VA inverter/charger installations. When configuring parallel or three-phase systems, multiple VE.Bus ports are essential for synchronisation and communication between units. This splitter provides a clean, reliable solution by converting a single RJ45 male connection into two female ports via a short 15 cm cable, eliminating the need for custom wiring or additional hubs.

Engineered for Victron Energy systems, it ensures signal integrity across CAT 5e connections, supporting stable data transfer for critical power management. Whether you're building a redundant off-grid setup or scaling a marine power system, this splitter simplifies complex VE.Bus topologies.

Why Use a Dedicated VE.Bus Splitter?

Generic RJ45 splitters often lack the precise pinout mapping required for VE.Bus communication, risking data errors or system instability. The Victron splitter features a labelled CAT 5e 100BASE-T pinout diagram on the housing, ensuring correct wiring and reducing installation guesswork. Its compact, durable plastic enclosure protects connections from dust and accidental disconnection, a common issue in mobile or industrial environments.

• 1x RJ45 male to 2x RJ45 female configuration for VE.Bus expansion
• 15 cm flexible cable reduces strain on ports and allows tidy routing
• Integrated pinout diagram for quick, error-free setup
• Compact, lightweight design suits space-constrained installations
• Compatible with MultiPlus 500VA–1600VA for parallel and three-phase use

Applications in Victron Energy Systems

This splitter is essential for installers and system integrators working with Victron MultiPlus units in configurations that demand multiple VE.Bus connections. Typical use cases include:

• Parallel stacking of two or more MultiPlus inverter/chargers for increased power output
• Three-phase setups where synchronisation across units is critical
• Adding a VE.Bus Smart Dongle or Digital Multi Control panel without sacrificing existing connections
• Temporary diagnostic access during commissioning or troubleshooting

By maintaining proper impedance and signal routing, it helps prevent communication dropouts that could lead to charging faults or inverter shutdowns. For installers, this means fewer callbacks and more reliable system performance.

Built for Professional Installations

Victron Energy designs accessories to meet the demands of harsh environments. The splitter's moulded housing resists vibration and minor impacts, while the gold-plated RJ45 contacts resist corrosion, a benefit in marine or coastal applications. The 15 cm cable length is optimised for neat cable management inside distribution boards or inverter enclosures, reducing clutter and improving airflow.

Note: This splitter is intended for VE.Bus data connections only and should not be used for Ethernet networking or Power over Ethernet (PoE) applications. Always verify pinout compatibility with your specific Victron device.
