The Victron Energy Orion-Tr Smart 12/24-10A is a 240W isolated DC-DC charger designed for dual-battery systems in vehicles and boats. It converts a 12V input to a 24V output and uses an adaptive 3-stage charging algorithm—bulk, absorption and float—for controlled battery charging.
Built-in Bluetooth enables configuration, monitoring and updates through VictronConnect, while engine-running detection helps prevent unwanted starter-battery discharge. The charger supports lead-acid and lithium batteries, offers programmable charging, short-circuit and high-temperature protection, and installs using screw terminals. Its isolated design keeps input and output grounds separate.
