Victron Orion-Tr Smart 12/12-30A Isolated DC-DC Charger 360W | ORI121236120

The Victron Orion-Tr Smart 12/12-30A is a galvanically isolated DC-DC charger that charges a service battery from a vehicle or vessel's starter battery. It suits professional mobile, marine and off-grid installations where electrical isolation between battery banks matters. Bluetooth is built in, so the unit pairs with the VictronConnect app for setup and live monitoring.

Orion-Tr Smart isolated DC-DC charger features

• Output, 30A output current, 360W maximum power transfer from a 12V input to a 12V output battery bank.
• Isolation, galvanic isolation removes ground loops and keeps faults from crossing between battery banks.
• Bluetooth, configuration and real-time monitoring via VictronConnect on iOS and Android.
• Charge algorithm, adaptive profile supports lithium (LiFePO4) and lead-acid chemistries including AGM and gel.
• Engine detection, charging only starts once the alternator is active, so the starter battery isn't drained.
• Weight, 1.8 kg in a compact, wall-mountable enclosure.

Networking and configuration

Setup runs entirely through VictronConnect over Bluetooth. Installers set the input voltage threshold for engine detection, choose the battery chemistry and absorption voltage, and watch charge state without opening the enclosure. The Orion-Tr Smart can join VE.Smart Networking, pulling temperature and voltage data from a connected BMV battery monitor or Smart Battery Sense for more accurate charging.

Applications

• Charging a lithium or lead-acid service battery from an alternator in campervans, motorhomes and HGVs.
• Marine dual-battery setups where galvanic isolation guards against stray current corrosion.
• Off-grid vehicle and expedition builds needing configurable battery-to-battery charging.
• Installations with a shared chassis earth, where isolating the battery circuits is necessary.
• Systems tied into Victron BMV monitors or GX devices for centralised monitoring.
