The Victron Orion-Tr Smart DC-DC charger is an adaptive 3-stage charger (bulk, absorption, float) designed for dual battery systems in vehicles and boats. It charges your service battery from the starter battery and alternator efficiently and safely. The “Smart” name reflects its built-in Bluetooth, allowing easy monitoring, configuration, and remote control via a remote on/off switch. It also features engine running detection for automatic operation.

This isolated model provides separate chassis grounds for input and output, ensuring safe installation. Compatible with 12V, 24V, or 48V systems, it supports both lead acid and lithium batteries. Available in power ratings up to 400W, multiple units can be connected in parallel for higher output.

Built for durability, it operates reliably in temperatures up to 55°C, with full rated output maintained up to 40°C.
