Victron Orion XS 1400: Next-Generation DC-DC Charger for Smart Alternators and Dual Battery Systems
High-Efficiency 12V/24V Battery Charger with Bluetooth and VE.Direct
The Victron Orion XS 1400 DC-DC Smart Battery Charger sets a new benchmark in adaptive DC-DC charging, engineered specifically for vehicles with Euro 5 and Euro 6 smart alternators, as well as boats, RVs, and off-grid setups. Delivering up to 1400 W continuous output at 40°C and a class-leading 98.5% peak efficiency, this compact unit ensures your auxiliary battery receives a precise, full charge while protecting the starter battery from discharge.
Unlike conventional chargers that struggle with variable alternator voltages, the Orion XS 1400 uses advanced BuckBoost technology to maintain a stable output even during long cable runs or voltage drops. Its fanless, aluminium circuit board cooling design eliminates moving parts, reducing potential failure points and ensuring silent, reliable operation in dusty or vibration-prone environments.
Adaptive 4-Stage Charging for Maximum Battery Life
The Orion XS 1400 employs an intelligent adaptive 4-stage charge algorithm (Bulk, Absorption, Float, Storage) tailored for lead-acid batteries, including AGM, Gel, and flooded types. For lithium batteries, the charger can be configured via the VictronConnect app to deliver a precise constant-current/constant-voltage profile, preventing overcharging and extending service life. The adaptive logic continuously monitors battery response and adjusts absorption time, minimising wear and reducing maintenance costs.
Precision Control and Real-Time Monitoring
With Bluetooth Smart built in, you can wirelessly configure input and output currents from 1 to 50 A in 0.1 A steps, set custom voltage thresholds, and monitor live performance data directly from your smartphone. The integrated VE.Direct port enables wired connection to GX devices, Color Control panels, or a PC for advanced system integration and data logging. Real-time current and power measurements help you track energy usage accurately, making it easier to optimise your power budget.

Engineered for Harsh Environments
The Orion XS 1400 is built to withstand the rigours of mobile and marine applications. Its IP65 ingress protection ensures reliable performance even when exposed to dust and occasional water splashes, while the protective terminal cover prevents accidental contact and debris ingress. The screw terminals accept cables up to 25 mm² (AWG4), and the unit's lightweight 0.52 kg construction simplifies installation in tight spaces.
Versatile Applications
Whether you're upgrading a dual battery system in a 4WD, caravan, or boat, or building an off-grid power solution, the Orion XS 1400 adapts to a wide range of configurations:
- 12 V to 12 V (50 A) for standard auxiliary battery charging
- 12 V to 24 V (25 A) for 24 V battery banks
- 24 V to 12 V (50 A) for trucks and heavy vehicles
- 24 V to 24 V (50 A) for larger off-grid systems
Its ability to operate as a power supply with a fixed output voltage further extends its utility for powering sensitive equipment directly.
