Orion-TR Smart 12V to 24V - 15A Non-Isolated Smart DC-DC Charger or Power Supply

The Orion-Tr Smart DC-DC charger is a professional DC to DC adaptive 3-stage charger with built-in Bluetooth.

For use in dual battery systems in vehicles or on boats where the alternator and the start battery are used to charge the service battery. The unit can be monitored and programmed via Bluetooth and can be remotely controlled via a remote on/off switch. Can charge from either house to start or start to house. The 12V to 24V models can be used to charge a 24V bank from a 12V bank!

The Orion Tr-Smart charger can be used in 12V or 24V systems and is suitable for both lead acid and lithium batteries. Models are available up to 400W and unlimited multiple units can be connected in parallel to increase output power.

Suitable for high temperatures up to 55°C with a full rated output up to 40°C.


VictronConnect lets you get live status information and configure any Victron products which either have Bluetooth built-in, or are connected to a VE.Direct Bluetooth Smart Dongle.

Please do not confuse the Orion Tr with the Orion Tr Smart they are totally different products. Unfortunately Victron has made this quite confusing for many buyers. The Orion-Tr Smart Non-Isolated is a full multi-stage DC to DC or Battery to Battery charger. Make no mistake, the Orion TR Smart is a work horse of a DC to DC three-stage charger with built-in Bluetooth and the ability to be custom programmed. It is also air cooled and has no fan noise.

Where the Orion TR Smart really shines in in its ease of use and ease of installation. Because it can be programmed via Bluetooth, gone are the clunky & awkward button pushes and waiting for the right lights to blink, then hoping you got it right. Unlike other DC to DC chargers, the Orion TR Smart is output rated not input rated. This means Orion TR Smart 12V to 24V15A model actually delivers the full 15A to your battery bank!

True DC to DC Charging:

The Orion TR Smart is very handy for bow banks, stern banks start banks, helm/electronics banks etc. The Orion TR Smart is a true "smart-multi-stage charger" not just a voltage following device.

Bluetooth Smart Enabled:

Any Bluetooth-enabled smartphone, tablet, or other device can be used to monitor the unit, change settings or to update the charger when new software features become available. Please see the VictronConnect manual for more information and certain device limitations.

Fully Programmable:

  • Battery charge algorithm (fully configurable) or fixed "power supply" output.
  • "Smart" alternator-compatible with an adjustable engine running detection mechanism.

Adaptive 3-Stage Charge Algorithm: Bulk, Absorption & Float

  • For Pb batteries it is important that during shallow discharges the absorption time is kept short to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged.
  • For LiFePO4 (LFP) batteries the absorption time is fixed (or adjustable) with a default time of 2 hours.
  • If desired, a fixed output voltage can be selected by using "power supply mode" instead of the 3-stage charging algorithm.

Remote On-Off:

  • A remote on/off switch or relay contact can be connected to a two-pole connector for full control and zero quiescent draw when not in use.

Short-Circuit Proof:
  • All models are short-circuit proof and an unlimited number of units can be connected in parallel to a single battery bank to increase output current.

High Temperature Protected:

  • Suitable for ambient temperatures up to 40C (104) at full output; units will automatically derate to stay cool up to a maximum ambient temperature of 55C (131F).

IP43 Rated:

  • When installed with the screw terminals oriented downward.

Industry-Leading Warranty:

  • Like most all products from Victron Energy the Orion-Tr Smart DC-DC Charger is protected by a full 5-year manufacturer's warranty.
