xVictron Orion-Tr Smart 12/24-15A (360W) Isolated DC-DC Charger
The Victron Orion-Tr Smart 12/24-15A is an isolated DC-DC battery-to-battery charger designed for dual-battery systems in vehicles, boats and off-grid installations. It converts a 12V input (starter battery or alternator) to a 24V output at up to 15A, delivering 360W of charging power with full galvanic isolation between input and output circuits. It is aimed at professional installers and system integrators who need reliable, programmable DC charging in mobile or remote applications.
Key Features
- 12V input to 24V output conversion at 15A continuous, with galvanic isolation preventing ground loops and protecting sensitive electronics.
- Bluetooth built-in via the VictronConnect app, allowing configuration, monitoring and firmware updates from a smartphone without additional hardware.
- Adaptive charging algorithm with configurable charge profiles to suit lithium (LiFePO4), AGM, gel and flooded lead-acid batteries.
- Engine detection function prevents discharging the starter battery by monitoring input voltage and only charging when the alternator is running.
- Remote on/off control via a dedicated two-pin connector, enabling integration with vehicle ignition circuits or external battery management systems.
- Wide input voltage range accommodates fluctuating alternator output and varying battery states without interrupting the charge cycle.
- Compact, sealed enclosure suitable for installation in engine bays, under-seat compartments and marine bilge areas.
Product Overview
The Orion-Tr Smart range uses transformer-based galvanic isolation, which means the input and output circuits share no common ground. This is particularly important in marine installations where stray current corrosion is a concern, and in vehicles where multiple battery banks may be connected to different chassis grounds. The isolation also protects the starter battery circuit from any fault conditions on the service battery side.
Configuration is handled entirely through the VictronConnect app over Bluetooth. Installers can set absorption voltage, float voltage, bulk current limits and the engine detection threshold directly from a phone or tablet. This removes the need for a separate programming interface and makes commissioning straightforward on site. The unit also supports a two-wire remote on/off input, which allows it to be switched via an ignition feed, a battery management system or a manual switch.
The 360W output is well suited to charging a 24V service battery from a 12V vehicle or boat electrical system, including systems with smart alternators that use variable voltage regulation. Because the Orion-Tr Smart operates independently of the alternator's charge profile, it applies the correct multi-stage charge curve to the service battery regardless of what the alternator is doing on the input side.

Installation Notes
Installation should be carried out by a qualified electrician or experienced system integrator familiar with DC wiring practices. Ensure input and output cables are correctly rated for the current draw and that appropriate fusing is fitted on both the input and output sides as close to the battery terminals as practicable. In marine applications, follow NMEA or RYA wiring guidelines and verify that the installation complies with the relevant boat safety scheme requirements. The remote on/off connector should be wired to a switched ignition feed or BMS output to prevent unintended discharge of the source battery when the engine is off. Do not exceed the specified input voltage range.
