The Victron Orion XS is making waves in the off-grid and campervan community, thanks to its robust build and advanced features. Lately, there’s been growing anticipation around two potential game-changing functions: start assist and bi-directional charging, rumoured to arrive via future firmware updates. Here’s a technical breakdown of what’s possible—and what to watch for.
Technical Overview: Victron Orion XS Start Assist & Bi-Directional Charging
Start Assist: This would allow the Orion XS to deliver a high-current burst from your leisure battery to the starter battery, supporting engine cranking or heavy loads during start-up. For users running deep-cycle LiFePO4 batteries, this could be a lifesaver when the starter battery is low.
Bi-Directional Charging: Currently, the Orion XS is designed for unidirectional charging (alternator to leisure battery). Bi-directional capability would enable power to flow in both directions, automatically balancing charge between thestarter and auxiliary batteries. This could allow innovative energy management, especially for vehicles with solar or shore power inputs.
What’s the Latest from Victron?
As of firmware v1.13 (November 2025), neither feature is officially supported. However, hardware analysis and community discussions suggest the Orion XS is physically capable of both functions.
Beta testers and changelog sleuths have spotted hints that firmware updates could unlock these features, but Victron has not confirmed a timeline or released technical documentation.
Expect any future update to require careful configuration in VictronConnect, possibly with new safety parameters or wiring recommendations.
Why Does This Matter?
With the Victron Orion XS, unlocking start assist and bi-directional charging, would significantly increase the flexibility and resilience of off-grid electrical systems. For installers and DIYers alike, it means fewer compromises and more options for energy management.
