WARNING: This model is specifically designed for 12V to 12V charging systems. Do not use it with 24V or mixed-voltage systems — doing so may cause permanent damage.

The Victron Orion-Tr Smart Isolated 12/12-30A DC-DC Charger provides reliable, efficient, and intelligent charging for secondary batteries in vehicles, 4WD setups, marine installations, caravans, and off-grid power systems. Whether you’re charging a deep-cycle house battery or powering an auxiliary electrical system, the Orion offers safe, controlled, and highly configurable charging performance.

Effortless Connectivity with Bluetooth Smart

Adjust, monitor, and optimise your charging system directly from your phone.

• Built-in Bluetooth Smart allows full configuration and monitoring via the VictronConnect App.

• View real-time voltages, currents, temperatures, load behaviour, and system data.

• Update firmware instantly for new features and improvements.

Customizable Charging for Every Battery Type

The Orion-Tr Smart allows fine-tuned charging based on your system needs:

• Adjustable charging profiles for AGM, Gel, Flooded, and LiFePO₄ (lithium) batteries.

• Suitable for use with smart alternators found in modern vehicles (variable voltage alternators).

• Configurable input/output settings optimise battery life and ensure safe charging under all conditions.

Intelligent 3-Stage Charging Algorithm

The Orion-Tr Smart uses an adaptive 3-stage charging profile:

• Bulk — fast charging when your battery is low

• Absorption — controlled charging to reach 100% safely

• Float — maintains your battery without overcharging

It also offers fixed output voltage mode for systems that require a stable regulated DC output instead of multi-stage charging.

Remote Control Options

The charger includes a remote on/off terminal, allowing:

• Integration with vehicle ignition

• Remote switching and system control

• Easy disable/enable from a switch panel, battery protect, or BMS

Perfect for installations where the charger is difficult to access.

Expandable Power for Larger Systems

Need more output?
Multiple Orion-Tr Smart units can be connected in parallel to increase total charging current — ideal for large LiFePO₄ banks, dual house batteries, or high-demand setups.

Protection Against the Elements

When installed with terminals facing downward, the charger achieves an IP43 protection rating, giving it:

• Resistance to sprays of water

• Protection from small objects and debris

This makes it suitable for vans, canopies, 4x4 systems, and marine compartments.

No-Hassle Installation

The Orion-Tr Smart features:

• Large screw terminals — no special tools required

• A wide input voltage range

• Simple mounting with clear wiring labels

Installers and DIY users will appreciate its robust, uncluttered design.

Stay Safe with Built-In Protection

Victron includes several layers of protection to keep your system safe:

• Non-replaceable internal input fuse

• Over-temperature shut-down with automatic restart

• Overload and short-circuit protection

• Reverse polarity protection (via external fusing)

These safeguards make the Orion-Tr Smart one of the most reliable DC-DC chargers available.
