Description
xVictron Orion-Tr Smart 24/24-17A (400W) Non-Isolated DC-DC Charger
The Victron Orion-Tr Smart 24/24-17A is a non-isolated DC-DC charger designed for 24V to 24V charging applications in vehicles, marine vessels and off-grid systems. It delivers up to 17A (400W) of charge current and is managed via Bluetooth using the VictronConnect app, making it well suited to professional mobile and dual-battery installations.
Key Features
- 400W output power with 17A charge current on a 24V to 24V non-isolated topology
- Bluetooth built-in for configuration and monitoring via the VictronConnect app on iOS and Android
- Multi-stage adaptive charging algorithm supports lead-acid (AGM, gel, flooded) and lithium battery chemistries
- Engine detection feature prevents discharging the starter battery by monitoring input voltage
- Remote on/off input allows integration with vehicle ignition or a BMS
- Non-isolated design shares a common negative between input and output, which simplifies wiring in many vehicle and marine installations
- Wide input voltage range accommodates fluctuating alternator output during charging
Product Overview
The Orion-Tr Smart operates as a DC-DC battery-to-battery charger, taking power from a vehicle or vessel's primary battery bank and using it to charge a secondary (service) battery. Unlike a simple voltage reducer, it applies a proper multi-stage charge profile, which matters for lithium and AGM batteries that require accurate charge termination. The non-isolated variant is appropriate where the two battery banks share a common ground, which is the standard arrangement in most 24V vehicle and marine electrical systems.
Bluetooth connectivity is handled entirely within the unit. No additional interface hardware is required to configure charge profiles, set voltage thresholds or monitor charge status. The VictronConnect app also allows the engine detection sensitivity to be adjusted, which is useful in installations where alternator voltage behaviour differs from the default assumptions. For installations using a Victron BMS, the remote on/off terminal provides a direct control path to protect lithium cells from over-discharge.

Installation Notes
This unit should be installed by a qualified auto-electrician or marine electrician familiar with DC power systems. The non-isolated design requires a shared common negative between the source and load battery banks. Correct fusing of both input and output cables is essential. For lithium battery installations, configure the remote on/off terminal to accept a signal from the BMS to prevent operation outside safe cell voltage limits.
