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.
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.
Charge a service battery from a starter battery and alternator using a controlled charging profile suited for mobile and marine power systems.
Configure charging settings and review live status in the VictronConnect app over Bluetooth.
Supports remote on/off wiring and engine running detection features to help prevent draining the starter battery when the engine is off.
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.
Yes. It is designed for dual battery charging where a starter battery and alternator supply controlled charging to a service battery.
Yes. It supports Bluetooth configuration and monitoring using the VictronConnect app.
It supports remote on/off wiring. Many installs use an ignition signal or other control method depending on system design.
Select by matching your source voltage (starter side), your battery voltage (service side), and the maximum output current you need.
It uses an adaptive 3-stage algorithm: bulk, absorption, and float.
It supports configurable charging parameters and can be used with lithium systems when configured to the battery manufacturer’s requirements.
Some DC-DC chargers can be configured to operate in power supply mode depending on model capabilities and settings. Refer to the Victron manual for supported modes and configuration.

Great product. Used daily in my build— ac fan solar….
Kaiya provided wonderful support for a troublesome panel struggling during a second year of operation -- I could not be more pleased to have chosen Orion for my solar! The Stealth rack & awning are quite sweet as well :). Thanks Orion!
So far so good. Installed on my Sportsmobile converted dodge promaster. Waiting for the rain to see how it does in wet conditions. Once I figured out how to install it was VERY easy. Only ask would be more details on initial installation process since I wasn't sure exactly where to place the track. Once I got it installed and put the fly in the track it was so easy. Excited for how this will work on my pop-top van.
Great products, responsive team!
What can I say? Orion takes great care of their customers. They went out of their way to help me and I appreciate it. I also found out too late that they sell 8020 Roll in nuts. I use the 10 series for my build. The nice thing about Orion‘s 10 series rolling nuts is they have a register on top of the nut that keeps it from twisting in the extrusion. I wish I would’ve known this when I bought all my hardware. I would’ve definitely bought this product from Orion. Check them out.
