The Victron Orion-Tr Smart 12/12-30A Isolated DC-DC Charger is a powerful and intelligent energy management solution for dual-battery systems in vehicles, campervans, boats, and off-grid setups. It enables fast and safe charging of an auxiliary (leisure) battery from the starter battery while the engine is running—perfect for modern Euro 5/6 vehicles with smart alternators.

30A DC-DC Charging – Safe Power Distribution

With a 30A maximum charging current, the Orion-Tr Smart delivers controlled power to the service battery without overloading the alternator or battery. It prevents overcharging and extends battery life by using 3-stage charging algorithms tailored to battery chemistry.

Whether you’re using AGM, GEL, or LiFePO4 batteries, this charger maintains full battery health and stability in all conditions.

Fully Isolated for Maximum Safety

This galvanically isolated DC-DC charger ensures complete electrical separation between input and output circuits, eliminating ground loop issues and enhancing system safety—essential for marine and sensitive mobile applications.

Built-In Bluetooth for Configuration & Monitoring

Using the VictronConnect app, users can:

• Monitor charge voltage and current in real time
• Configure battery charging profiles
• Enable/disable engine-run detection
• View historical performance data

No need for extra interfaces—your phone or tablet becomes your control panel.

Engine-Run Detection & Smart Protections

• Automatic on/off based on engine status
• Over-temperature protection with output derating
• Short-circuit and overload protection
• Low input voltage shutdown and restart thresholds

All safety measures are in place for reliable, unattended operation.
