xOrion-Tr Smart 12/12-30A (360W) Isolated DC-DC Charger
The Victron Orion-Tr Smart 12/12-30A is a galvanically isolated DC-DC charger designed to charge a service battery from a vehicle or vessel's starter battery. It is suited to professional mobile, marine and off-grid installations where electrical isolation between battery banks is required. The unit is Bluetooth-enabled and integrates with the VictronConnect app for configuration and monitoring.
Key Features
- 30A output current with 360W maximum power transfer from a 12V input to a 12V output battery bank.
- Galvanic isolation eliminates ground loops and protects both battery banks from cross-contamination of faults.
- Built-in Bluetooth allows configuration and real-time monitoring via the VictronConnect app on iOS and Android.
- Adaptive charge algorithm supports lithium (LiFePO4) and lead-acid battery chemistries including AGM and gel.
- Engine detection feature prevents discharge of the starter battery by only charging when the alternator is active.
- Wide input voltage range accommodates fluctuating alternator output during vehicle operation.
- Compact, wall-mountable enclosure weighing 1.8 kg, suitable for installation in confined spaces.
Product Overview
The Orion-Tr Smart uses a DC-DC conversion stage with galvanic isolation to transfer charge from a starter battery to a separate service battery bank. Unlike a simple voltage-controlled relay or battery-to-battery charger without isolation, the galvanic barrier means the two battery circuits share no direct electrical connection. This is particularly important in marine installations where stray current corrosion is a concern, and in vehicles where the chassis earth is shared across multiple systems.
Configuration is handled entirely through VictronConnect over Bluetooth. Installers can set the input voltage threshold for engine detection, select the battery chemistry and absorption voltage for the output bank, and monitor charge state in real time without physical access to the unit. The Orion-Tr Smart can also be networked with other Victron devices via VE.Smart Networking, allowing it to receive battery temperature and voltage data from a connected BMV battery monitor or Smart Battery Sense for more accurate charging.
At 360W continuous output, this unit is appropriate for service battery banks up to approximately 200Ah where a moderate charge rate is acceptable. For larger banks or faster charging requirements, Victron offers higher-current variants in the Orion-Tr Smart range.

Installation Notes
Installation should be carried out by a qualified electrician or experienced marine/vehicle electrical installer. Ensure correct cable sizing for a 30A DC circuit and fit an appropriately rated fuse on both the input and output connections as close to the battery terminals as practical. Verify that the input voltage range is compatible with your alternator output before installation. For lithium battery outputs, confirm the charge profile is correctly configured in VictronConnect before commissioning. This unit is not intended for grid-connected or solar PV applications.
