Overview

The Victron Orion-Tr Smart DC-DC Charger (Isolated) is designed for dual battery systems, such as vehicles or boats where the starter battery and alternator charge a service battery. It uses an adaptive 3-stage charge profile (bulk, absorption, float) and is configured and monitored using Bluetooth with the VictronConnect app.

Important Info

This is the Isolated model, meaning the input and output can have separate chassis grounds. If you need the version that shares ground between input and output, use the non-isolated model here.

Designed for Dual Battery Charging

Charge a service battery from a starter battery and alternator using a controlled charging profile suited for mobile and marine power systems.

Bluetooth Configuration with VictronConnect

Configure charging settings and review live status in the VictronConnect app over Bluetooth.

Remote On and Off, Engine Running Detection

Supports remote on/off wiring and engine running detection features to help prevent draining the starter battery when the engine is off.

Frequently Asked Questions (click to expand)

1. What does “Isolated” mean on this Orion-Tr Smart model?

Isolated means the input and output grounds are separated, which can help when the starter side and the service side need different chassis ground references.

3. Can I configure it from my phone?

Yes. It supports Bluetooth configuration and monitoring using the VictronConnect app.

4. Does it support a remote on/off or ignition trigger?

It supports remote on/off wiring. Many installs use an ignition signal or other control method depending on system design.

5. How do I choose the right model variant?

Select by matching your source voltage (starter side), your battery voltage (service side), and the maximum output current you need.

6. What charging stages does it use?

It uses an adaptive 3-stage algorithm: bulk, absorption, and float.

7. Can it be used with lithium batteries?

It supports configurable charging parameters and can be used with lithium systems when configured to the battery manufacturer’s requirements.

We just installed a Stealth+ on our 2026 High Roof Transit. So glad to have an option that works with the new shark fin antenna location in the '26 model year. Another advantage of the Stealth+ rack is that its usable area is wider and longer than other racks. That, along with the Orion team's help in providing CAD layouts was SUPER helpful in thinking through our roof layout and how to fit 600W of solar along with a vent fan and Starlink Mini.

Thank you for your feedback. We are delighted to hear that the Stealth+ was a perfect fit for your 2026 High Roof Transit, especially with the new shark fin antenna location. We take pride in providing solutions that cater to the latest updates. Thank you for choosing Orion and happy travels!

Great rack, lightweight, easy to assemble, solid, no added noise, fits (2) 200w Renogy ShadowFlux panels flush mounted with room to spare, no added noise, and looks great. Highly recommend.

Looks great! See you on the road!

Setup was super easy. The ECOFLOW Gen 2 is basically plug-and-play, everything is clearly labeled. Also ORION has been super helpful with any questions along the way!

Thanks, AJ! Easy setup, clear labels, real support. Enjoy the system and the extra off-grid time.

The Comvolt 4200 (with AC/DC PDU and 7-inch screen) is a game-changer for any setup.
Super easy install—mostly plug-and-play with minimal wiring. No fuss, no extra components to hunt down.
It’s compact, portable, and incredibly versatile: works flawlessly off-grid in a van, car, shop, home, or anywhere else. Everything’s built right in, so you get clean power without the headache of piecing together a bunch of parts.
Expandable too if you need more juice later. Hands down one of the most convenient, reliable portable power stations out there.
Nice work, Comvolt team—I love it! Highly recommend.
Thank you Orion Van Gear
