Description
xVictron Orion-Tr Smart 12/24-15A (360W) Non-Isolated DC-DC Charger — ORI122436140
The Victron Orion-Tr Smart 12/24-15A is a non-isolated DC-DC charger designed to charge a 24V service battery from a 12V alternator or starter battery system. It is suited to vehicles, boats and off-grid installations where two battery banks operate at different voltages and need to be charged independently without a galvanic connection between them.
Key Features
- Converts a 12V input to a 24V output at up to 15A continuous charge current, delivering 360W of charging power.
- Non-isolated design allows direct integration into systems where galvanic isolation between input and output is not required.
- Built-in Bluetooth connectivity enables configuration and monitoring via the VictronConnect app on iOS and Android.
- Supports adaptive multi-stage charging (bulk, absorption, float) to suit lead-acid and lithium battery chemistries.
- Engine detection feature prevents discharging the starter battery by monitoring input voltage and only charging when the alternator is running.
- Two-wire BMS connection support allows direct integration with Victron lithium batteries for charge control.
- Compact and lightweight at 1.8 kg, suitable for installation in confined spaces typical of vehicle and marine environments.
Product Overview
The Orion-Tr Smart non-isolated range uses a synchronous buck-boost topology to step voltage up or down between input and output. In this 12/24 variant, the unit accepts a nominal 12V input and delivers a regulated 24V charge output. Because the unit is non-isolated, the negative rails of the input and output circuits are connected. This is acceptable in most single-chassis vehicle and marine installations but should be assessed carefully in systems where ground loops or stray currents are a concern. Where full galvanic isolation is required, Victron's isolated Orion-Tr Smart variants should be used instead.
Configuration is handled entirely through VictronConnect over Bluetooth. Charge algorithm, absorption voltage, float voltage and current limits are all adjustable without physical access to the unit once installed. The engine detection function monitors the input voltage threshold to determine whether the alternator is active, preventing the charger from drawing down the starter battery when the engine is off. This threshold is user-configurable, which is useful on vehicles with variable charging voltages or smart alternators.
The unit supports a two-wire BMS connection for use with Victron Smart Lithium batteries. When the BMS signals that the battery is full or that charging should stop, the Orion-Tr Smart responds accordingly. This makes it a practical choice for dual-battery lithium upgrades in campervans, motorhomes and marine applications.

Installation Notes
Installation should be carried out by a qualified electrician or experienced marine/vehicle electrical engineer. The non-isolated design means the negative terminals of the input and output circuits share a common ground. Verify this is compatible with your system before installation, particularly in boats where galvanic corrosion or stray current risks may apply. Ensure input wiring is correctly fused close to the source battery in accordance with the wire gauge used. For lithium battery installations, confirm BMS compatibility before connecting. VictronConnect (free app) is required for initial configuration and is available for iOS and Android.
