Description
xVictron Orion-Tr Smart 48/24-16A (380W) Isolated DC-DC Charger
The Orion-Tr Smart 48/24-16A is a galvanically isolated DC-DC converter and battery charger designed for professional dual-battery and vehicle-based systems. It steps a 48V supply down to a regulated 24V output at up to 16A (380W), with Bluetooth-based configuration and monitoring built in. Suitable for marine, off-grid vehicle and industrial applications where electrical isolation between circuits is required.
Key Features
- Galvanic isolation between input and output eliminates ground loop issues and protects sensitive electronics on the output circuit.
- Bluetooth Smart built in: configure charge profiles, monitor status and adjust settings via the VictronConnect app on iOS or Android.
- Adaptive 3-stage charging (bulk, absorption, float) with selectable battery presets including lithium, AGM and gel.
- Input voltage range of 38V to 60V DC accommodates varying 48V battery states without shutting down prematurely.
- Output voltage is adjustable, allowing fine-tuning to match the requirements of the connected 24V battery bank.
- Engine start detection: the unit can be configured to activate only when the alternator is charging, protecting the starter battery.
- Compact, fully encapsulated housing rated for harsh environments including moisture and vibration.
Product Overview
The Orion-Tr Smart operates as a true battery-to-battery charger, not simply a voltage reducer. It applies a proper multi-stage charge algorithm to the output battery, which matters in systems where the secondary battery needs to reach full charge rather than just float. This is particularly relevant for lithium batteries, which require precise charge termination that a simple DC-DC converter cannot provide.
Galvanic isolation is a practical requirement in many marine and vehicle installations. Without it, connecting two battery banks directly can create ground loops that cause corrosion, interference or fault currents. The Orion-Tr Smart's transformer-based isolation eliminates this risk. The unit also supports parallel operation: two or more units can be connected in parallel to increase output current where a higher charge rate is needed.
VictronConnect Bluetooth configuration means no separate programming cable or interface is required. Installers can set the charge profile, adjust voltage thresholds and review historical data directly from a phone or tablet. The unit also integrates with the wider Victron ecosystem via a VE.Direct port, enabling monitoring through a GX device or the VRM portal.

Installation Notes
Installation should be carried out by a qualified electrician or experienced system integrator familiar with DC power systems. Ensure input and output wiring is correctly rated for the current and voltage involved. The unit must be mounted in a well-ventilated location and secured against vibration in mobile applications. For marine installations, follow NMEA and flag-state wiring standards. Engine start detection wiring should be verified before commissioning to avoid unintended battery drain.
