Victron Energy Orion-Tr DC-DC Charger 12/12V 30A (360W) Isolated — Bluetooth & 3‑Stage Charging

The Victron Energy Orion-Tr Smart DC-DC Charger 12/12V 30A 360W Isolated is a compact, three-stage professional DC-to-DC charger that safely charges a service battery from an alternator or other 12V source while offering Bluetooth monitoring and secure isolation.

This isolated DC-DC charger from Victron Energy is designed for vehicles, RVs, and boats where a dedicated service battery must be charged independently from the starter battery or alternator. It converts and regulates alternator output to deliver a controlled, battery-compatible charge profile—supporting lead‑acid and lithium chemistries—while the integrated Bluetooth lets you view status and adjust settings from a smartphone. Rugged housing, simple screw-terminals, and the option to parallel multiple units make it a flexible solution for installations that demand reliability and expandability.

How does the Orion-Tr protect batteries and electrical systems?

The Orion-Tr employs a three-stage charging algorithm that adapts to the battery type for safer, more complete charging. Its galvanic isolation prevents noise and unwanted current paths between engine and service systems, reducing the risk of electrical interference or damage. Built‑in safeguards handle voltage spikes, overheating, and reverse polarity to protect both charger and batteries.

• Three-stage charge profiling for proper battery conditioning
• Galvanic isolation prevents ground loops and interference
• Thermal and overcurrent protection for durability

Can I use it with lithium batteries and multiple chargers?

Yes—the Orion-Tr supports common lead‑acid and lithium battery charging profiles, selectable through the VictronConnect app. Multiple units can be connected in parallel to increase available charging current for larger battery banks or heavy loads. This modular approach helps scale power without adding a single large charger.

• Selectable profiles for lead‑acid and lithium chemistries
• Parallel-capable to combine outputs safely
• Bluetooth configuration ensures matching settings across units

What installation and monitoring options are available?

Installation is straightforward: clearly labeled screw terminals simplify wiring and reduce the need for specialized tools. For monitoring and parameter changes, the integrated Bluetooth communicates with VictronConnect so you can check state of charge, output current, and temperature from a phone or tablet. The compact footprint fits many engine bays, under seats, or in locker compartments.

• Screw-terminal wiring for fast, tool-minimal installation
• VictronConnect Bluetooth app for real-time monitoring and setup
• Compact, mountable enclosure suited to tight spaces

How does this unit perform in vehicle and marine environments?

Engineered for mobile life, the Orion-Tr withstands vibration and variable input from alternators while maintaining stable output to service batteries. Isolation and robust protections make it well-suited to boats and off-road vehicles where electrical systems face fluctuating conditions. Its efficient design minimizes heat generation and preserves alternator life.

• Vibration-tolerant construction for vehicle and marine use
• Efficient conversion reduces heat and alternator stress
• Isolated output protects sensitive electronics and batteries

Who is this for: The Victron Energy Orion-Tr Smart DC-DC Charger 12/12V 30A 360W Isolated is ideal for RV owners, marine operators, and overland drivers who need a dependable, compact charger to maintain a separate service battery from an alternator or other 12V source. Installers and DIYers will appreciate the simple screw-terminal connections and Bluetooth configuration, while users with larger battery banks can add units in parallel to meet higher charging demands.
