Victron Orion-TR Smart DC-DC charger and power supply delivers reliable charging for a service battery while protecting the starter battery. Built for mobile installations, it thrives in boats, RVs, and vehicles with Euro 5/6 smart alternators, where long cable runs can cause voltage drops.

-
Isolated output: Protects the service battery and minimizes cross-charging with the starter battery.
-
Power and compatibility: 360 W (15 A) continuous, wide input range 10–17 V, output adjustable 20–36 V (nominal 24.2 V), supports 12/24 V systems.
-
Programmable charging: Adaptive charging with a configurable algorithm or fixed output for predictable charging.
-
Smart alternator compatibility: Engine running detection prevents battery discharge when the engine is off.
-
Adaptive 3-Stage Charge Algorithm: Bulk–Absorption–Float optimization for lead-acid; automatically extends absorption time after deep discharge; lithium chemistry uses a fixed 2-hour absorption.
-
Remote On/Off and flexible wiring: Two-pole remote switch or relay; can switch battery plus (H) or battery minus/chassis (L).
-
Paralleling capability: Short-circuit proof and can be connected in parallel to increase output with no practical limit on unit count.
-
Protection and durability: High-temperature protection reduces output current at high ambient temperatures; IP43 rated for reliable mobile performance.
-
Easy installation: Screw terminals and an input fuse (not replaceable); no special tools required.
-
Engine shutdown detection: Stops the converter when the engine isn’t running to reduce starter battery draw.
-
Bluetooth connectivity: Monitor, adjust settings, and update firmware in real-time via the VictronConnect app.
The Orion-TR delivers dependable 360 W of continuous power at nominal 24.2 V, with flexible input and output configurations to suit marine, RV, and other mobile installations. Its isolated output protects the service battery and minimizes cross-charging with the starter battery, while features like engine-run detection, remote control, and paralleling provide scalable, safe power for diverse setups—from lead-acid to lithium chemistries.
