The Victron Orion-Tr Smart 12/12-18A Isolated DC-DC Charger provides safe and efficient auxiliary battery charging in vehicles equipped with smart alternators, lithium batteries or advanced dual-battery systems. With electrical isolation between input and output, it adds another layer of protection for complex or sensitive electronic setups found in modern 4WDs, marine systems and off-grid installations. Full Bluetooth connectivity allows wireless setup, monitoring and firmware updates via the VictronConnect app.

Important system compatibility notice
This model is designed specifically for 12V to 12V systems. Using it on any other voltage configuration can cause irreversible damage. Confirm battery system voltage before installation.

Smart Bluetooth configuration and monitoring
Use the VictronConnect app to:

• Adjust charge profiles and battery settings

• View live performance and historical data

• Update firmware for improved functionality and compatibility

Advanced charging for a wide range of batteries
The Orion-Tr Smart can be configured to suit AGM, flooded lead-acid, deep-cycle and lithium LiFePO₄ batteries. A selectable fixed output voltage mode allows powering DC equipment that requires a constant regulated supply.

Three-stage charging algorithm for optimal battery health
The smart bulk, absorption and float charge stages deliver fast charging to low batteries while preventing overcharge once the battery is full. This improves lifespan and performance in demanding mobile power applications.

Expandable system capacity
Multiple Orion-Tr units can be safely connected in parallel to increase charging output, providing scalability for caravans, touring setups, yacht house batteries and commercial service vehicles with larger energy demands.

Durable IP43 protection and safe internal components
When mounted with terminals facing downward, the Orion-Tr achieves an IP43 rating for resistance to water spray and solid contaminants. Internal protections include a high-temperature shutdown and integrated input fuse, reducing installation complexity and improving system safety.

Simple installation with remote control options
The screw-terminal layout supports secure wiring with no specialty tools. A remote on/off switch input allows connection to ignition feeds, control panels and battery management systems for automated or manual switching.

Where this charger is recommended

• 4WD dual-battery systems with smart alternators

• Caravan, camper trailer and RV auxiliary banks

• Marine systems requiring electrical isolation

• Lithium (LiFePO₄) and AGM charging setups

• Off-grid storage and worksite DC power systems
