Introducing the Orion-Tr Smart Isolated DC-DC Charger – the new standard in easy, fully configurable, low-footprint battery-to-battery chargers from Victron Energy!


This is the 18amp, 12v to 12v Unit.

Not to be confused with the Orion-Tr, the Orion-Tr Smart DC-DC Charger is a professional DC to DC adaptive 3-stage charger with built-in Bluetooth. This highly anticipated new product offering from Victron Energy is finally here, released just in time to celebrate their 45th year of innovation and dependability.

Bluetooth Smart Enabled:

-Any Bluetooth-enabled smartphone, tablet, or other device can be used to monitor, to change settings, and 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 (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 (adjustable) with a default time of 2 hours.

-If desired, a fixed output voltage can be selected “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 all products from Victron Energy (other than batteries), the Orion-Tr Smart DC-DC Charger is protected by a full 5-year manufacturer’s warranty and unrivalled technical support from a worldwide network of dealers, distributors, and service partners.
