The Victron Energy Orion-Tr Smart 12/24-15A is a Bluetooth-enabled, galvanically isolated DC-DC battery charger delivering 15A of continuous output current at 360W, with a three-stage adaptive charge algorithm, smart alternator compatibility, and unlimited parallel expandability for 12V-to-24V vehicle and marine dual-battery systems.

Key Features:

• Bluetooth Smart Enabled — Monitor output voltage and current, adjust charge settings, and receive firmware updates wirelessly via the VictronConnect app on any Bluetooth-enabled smartphone or tablet, with instant readout of key data including warnings and alarms on the device list page.
• Galvanic Isolation — 200V DC isolation between input, output, and case fully separates the starter battery from the auxiliary battery, preventing ground loop issues and protecting sensitive electronics in vehicles and vessels.
• Three-Stage Adaptive Charge Algorithm — Automatically adjusts absorption time based on depth of discharge — short absorption for shallow cycles to prevent overcharging, extended absorption after deep discharge for full recovery; fixed 2-hour absorption for lithium batteries.
• Euro 5 and Euro 6 Smart Alternator Compatible — Built-in engine shutdown detection stops the converter when the engine is not running, preventing unwanted discharge of the starter battery on modern variable-voltage alternator systems.
• Unlimited Parallel Operation — Any number of units can be connected in parallel to scale output current to any requirement, with all models short-circuit proof and high-temperature protected via automatic output current reduction.

The Orion-Tr Smart 12/24-15A accepts an input voltage range of 8–17V with under-voltage shutdown at 7V and restart at 7.5V, delivering a nominal 24.2V output adjustable from 20–30V with ±0.2V tolerance and 2mV RMS output noise. Continuous output power is 430W at 25°C and 360W at 40°C, with a peak output of 25A for 10 seconds and a short-circuit output current rating of 40A.

A remote on/off two-pole connector allows integration with ignition switches or relay contacts for automated start/stop control. IP43 protection is achieved for electronics when installed with screw terminals oriented downward in an IP22-rated connection area, with a maximum cable cross-section of 16mm²/AWG6. An internal non-replaceable input fuse is included and no special tools are required for installation.
