Description
xVictron Orion-Tr Smart 12/12-18A (220W) Isolated DC-DC Charger
The Orion-Tr Smart 12/12-18A is a galvanically isolated DC-DC charger designed for vehicle, marine and off-grid applications where a secondary battery bank needs to be charged from a primary 12V source. It delivers up to 18A (220W) of charge current and is managed via Bluetooth, making it suitable for professional dual-battery installations without requiring a separate battery-to-battery charger controller.
Key Features
- Galvanic isolation between input and output eliminates ground loop issues and protects sensitive electronics in dual-battery systems.
- 18A maximum output current at 12V, providing up to 220W of continuous charge power.
- Built-in Bluetooth connectivity allows configuration and monitoring via the VictronConnect app on iOS and Android.
- Adaptive 3-stage charging algorithm (bulk, absorption, float) ensures correct charge profiles for lead-acid and lithium battery chemistries.
- Engine detection via input voltage threshold prevents discharging the starter battery when the alternator is not running.
- Wide input voltage range accommodates fluctuating alternator output and varying system voltages.
- Compact, sealed housing suitable for installation in engine bays, lockers and other confined spaces.
Product Overview
The Orion-Tr Smart operates as a DC-DC battery-to-battery charger rather than a simple voltage converter. It applies a proper multi-stage charge profile to the secondary battery, which is essential for lithium (LiFePO4) batteries that require precise absorption and float voltages. Standard split-charge relays and basic DC-DC converters do not provide this, making the Orion-Tr Smart the correct choice where battery longevity and state-of-charge accuracy matter.
Galvanic isolation is a key differentiator in this unit. It physically separates the input and output circuits, which is particularly important in marine installations where stray current corrosion is a concern, and in vehicles where chassis grounds between the primary and secondary systems must not be shared. The isolation also means the unit can be used to charge a battery bank at a different voltage potential without risk of ground faults.
Configuration is handled entirely through VictronConnect over Bluetooth. Installers can set charge voltages, absorption time, tail current thresholds and the engine detection voltage without any physical DIP switches or additional programming hardware. The unit also integrates with the wider Victron ecosystem, including 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.

Installation Notes
Installation should be carried out by a qualified auto-electrician or marine electrician familiar with dual-battery systems and DC wiring regulations. Correct fusing on both the input and output cables is required. For marine installations, follow the relevant NMEA or RCD Directive wiring standards. The unit must be mounted in a ventilated location away from direct water ingress, even though the housing is sealed. Lithium battery profiles must be configured correctly in VictronConnect before commissioning; incorrect charge voltages can damage lithium cells.
