Description

Overview

The Victron Orion-Tr Smart DC-DC Charger (Isolated) is a professional-grade DC-to-DC charger designed for charging service batteries from an alternator in vehicle and marine dual-battery systems. Featuring built-in Bluetooth connectivity and an adaptive 3-stage charging algorithm, it delivers efficient, battery-safe charging for both lead-acid and lithium battery chemistries.

The isolated version provides separate input and output negative connections, making it ideal for systems where start and house batteries do not share a common negative. Fully programmable and remotely controllable, the Orion-Tr Smart ensures optimal charging performance in demanding mobile and off-grid environments.

Key Features

Smart Charging & Control

  • Adaptive 3-stage charge algorithm: Bulk, Absorption, Float
  • Automatically adjusts absorption time based on discharge depth
  • Fixed absorption time for lithium batteries (default 2 hours)
  • Optional fixed output voltage mode

Bluetooth Monitoring & Programming

  • Built-in Bluetooth Smart connectivity
  • Configure and monitor via VictronConnect app
  • Firmware updates available wirelessly

Vehicle & Marine System Integration

  • Smart alternator compatibility with engine running detection
  • Remote on/off control via switch, relay, or ignition signal
  • Compatible with 12V and 24V electrical systems

Scalable & Robust Design

  • Models available up to 400 W output
  • Unlimited parallel connection to increase charge current
  • Short-circuit proof on all models
  • High-temperature protection with automatic current derating

Installation & Environmental Protection

  • IP43 rated when installed with terminals facing downward
  • Full rated output up to 40°C, operation up to 55°C
  • Screw terminals for simple installation with no special tools

Isolated Design Note

  • Provides separate input and output negative terminals
  • Required when start and house batteries do not share a common negative
  • If batteries share a common chassis ground, a non-isolated version is sufficient
