Description
xOrion-Tr Smart 24/12-30A (360W) Non-Isolated DC-DC Charger
The Victron Orion-Tr Smart 24/12-30A is a non-isolated DC-DC charger designed to charge a 12V service battery from a 24V alternator or vehicle electrical system. At 360W output, it suits professional vehicle conversions, campervans, marine installations and off-grid mobile systems where two battery banks need to be managed independently.
Key Features
- 30A output current at 12V, delivering up to 360W of charging power from a 24V input source.
- Non-isolated design provides efficient power conversion without galvanic isolation between input and output.
- Built-in Bluetooth allows configuration and monitoring via the VictronConnect app on iOS and Android.
- Supports adaptive multi-stage charging with configurable absorption and float voltages to suit different battery chemistries.
- Engine detection feature prevents discharging the starter battery by monitoring input voltage before enabling output.
- Programmable via VictronConnect: adjustable charge algorithm, current limits and battery presets including lithium profiles.
- Compact and lightweight at 1.8kg, suitable for installation in confined spaces within vehicles or vessels.
Product Overview
The Orion-Tr Smart non-isolated range uses a synchronous buck converter topology. Because the input and output share a common ground, this design is more efficient than isolated equivalents and generates less heat at high continuous loads. The trade-off is that it is not suitable for installations where galvanic isolation is required, such as certain marine shore-power setups or systems where the two battery banks must be fully electrically separated.
The integrated Bluetooth module connects directly to the VictronConnect app without requiring a separate interface dongle. From the app, installers can set the charge profile, configure the engine detection threshold, monitor real-time current and voltage, and review historical data. The unit also supports two-wire BMS control for lithium battery systems, allowing a compatible BMS to disable charging when required.
Engine detection works by monitoring the input voltage level. When the alternator raises the system voltage above the configured threshold, the Orion-Tr Smart enables its output. This prevents the charger from drawing down the starter battery when the engine is off, which is a common requirement in dual-battery vehicle installations.

Installation Notes
Installation should be carried out by a qualified auto-electrician or marine electrician familiar with dual-battery systems. Ensure correct cable sizing and fusing on both input and output circuits in line with the 30A output rating. The non-isolated design means input and output share a common negative; verify this is compatible with your system before installation. For lithium battery installations, confirm BMS compatibility and configure the appropriate charge profile in VictronConnect before commissioning.
