Victron Energy Orion-Tr Smart DC-to-DC Charger 12/12V 30A (360W) with Bluetooth

The Victron Energy Orion-Tr Smart DC-to-DC Charger is a 12/12V, 30A (360W) compact professional charger with built-in Bluetooth for safe, multi-stage charging of lead-acid and lithium service batteries.

This Orion-Tr Smart model is designed for vehicles, marine craft, and off-grid setups where a reliable, alternator-fed charger is needed to recharge a secondary service battery. It combines a three-stage charging algorithm with smart monitoring and adjustable settings via the VictronConnect app, allowing flexible installation and scalable power by paralleling units when higher output is required.

How does the Orion-Tr Smart keep my service battery healthy?

The charger uses a three-stage charging profile to bring batteries to full charge efficiently while reducing stress and overcharging risk. You can select charging parameters suited to lead-acid or lithium chemistries and fine-tune settings through Bluetooth.

• Three-stage charging (bulk, absorption, float) optimizes charge cycles
• Selectable profiles for lead-acid and lithium batteries
• Automatic regulation reduces heat and prolongs battery life

Can I monitor and control the charger remotely?

Yes — the Orion-Tr Smart includes integrated Bluetooth for wireless setup and real-time monitoring from a smartphone or tablet using VictronConnect. The app displays status, diagnostics and allows configuration changes without physical access to the unit.

• Bluetooth connectivity for on-site wireless access
• VictronConnect app shows charge status and logs
• Adjust charge curves and operational options from your device

Is installation suitable for DIY or professional fitters?

Installation is straightforward thanks to accessible screw terminals and a compact form factor, but follow wiring best practices and safety guidelines. The unit is built for mounting in tight spaces common in engine bays, boats, and camper vans.

• Screw terminal connections for simple wiring and secure mounting
• Compact housing fits behind panels or in battery compartments
• Multiple units can be paralleled to increase total charging current

What kinds of systems and batteries does it work with?

The Orion-Tr Smart is compatible with 12V alternator systems and designed to charge both lead-acid (including AGM, GEL) and lithium batteries when configured correctly. It is especially useful where a dedicated service battery needs independent, regulated charging from a vehicle or boat alternator.

• Compatible with 12V alternator and engine-start battery setups
• Works with lead-acid, AGM, GEL, and lithium battery types
• Paralleling allows scaling from 30A to higher outputs as needed

Who is this for? The Victron Energy Orion-Tr Smart DC-DC Charger suits installers, vanlifers, boat owners, and fleet operators who need a compact, configurable, and Bluetooth-enabled charger to keep service batteries charged reliably and safely. It’s aimed at users who want professional multi-stage charging with the convenience of remote monitoring and the flexibility to expand system capacity by adding parallel units.
