xVictron Orion-Tr Smart 48/12-30A (360W) Isolated DC-DC Charger
The Orion-Tr Smart 48/12-30A is a galvanically isolated DC-DC charger that converts a 48V supply down to a 12V charging output at up to 30A (360W). It is designed for professional installations where a secondary 12V battery needs to be charged from a 48V house bank, traction battery or DC bus, without an electrical connection between the two circuits. Built-in Bluetooth allows configuration and monitoring via the VictronConnect app without additional hardware.
Key Features
- Galvanic isolation between input and output eliminates ground loop issues and protects both battery banks from cross-contamination of faults.
- 48V input to 12V output conversion at 30A continuous, delivering up to 360W of charging power.
- Integrated Bluetooth with VictronConnect app support for configuration, monitoring and firmware updates from a smartphone or tablet.
- Adaptive 3-stage charging algorithm (bulk, absorption, float) ensures correct charge management for the secondary battery.
- Wide input voltage range accommodates real-world 48V systems, including those with variable bus voltage under load.
- Engine detection input allows the unit to activate only when the alternator or engine is running, protecting the source battery from discharge.
- Compact, wall-mountable aluminium enclosure rated for permanent installation in vehicles, vessels and fixed off-grid systems.
Product Overview
The Orion-Tr Smart range differs from basic DC-DC converters by incorporating a proper multi-stage battery charging profile rather than simply regulating output voltage. This matters in practice because a flat secondary battery will draw maximum current until it reaches absorption voltage, then taper off correctly, rather than being held at a fixed voltage that either undercharges or stresses the battery. The result is longer battery life and a fully charged auxiliary bank.
Galvanic isolation is a key specification for many installations. On boats, it prevents stray current corrosion between separate battery systems. In vehicles with dual battery setups, it avoids chassis ground conflicts. In 48V off-grid or telecom systems feeding 12V auxiliary loads, it provides a clean separation that simplifies fault-finding and meets installation best practice. The transformer-based isolation in the Orion-Tr Smart is not a software feature; it is a physical barrier built into the converter topology.
VictronConnect Bluetooth is built in as standard. There is no need for a separate interface dongle or wired connection to set charge voltages, absorption time, or engine detection behaviour. The unit can also be integrated into a wider Victron system via a VE.Direct connection, allowing data to be logged through a GX device or the VRM portal.

Installation Notes
This unit should be installed by a qualified electrician or experienced system integrator familiar with DC power systems. Correct cable sizing and fusing on both the input and output sides is essential at these current levels. The engine detection input must be wired correctly if source battery protection is required. For marine installations, follow applicable wiring standards for the vessel type. VictronConnect (iOS or Android) is required for initial configuration and is available as a free download.
