It suits dual-battery systems in vehicles, boats and off-grid setups where isolation between source and load matters.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanic isolation\u003c\/strong\u003e, transformer isolated between input and output, avoiding ground loops and protecting connected electronics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e, 12V input, 24V regulated output at up to 10A continuous (240W).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth control\u003c\/strong\u003e, configured, monitored and updated via the VictronConnect app, no separate interface cable needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdaptive charging\u003c\/strong\u003e, supports lithium (LiFePO4) and lead-acid chemistries including AGM, gel and flooded.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine detection\u003c\/strong\u003e, monitors input voltage and only enables output once the alternator is running, protecting the starter battery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgrammable profiles\u003c\/strong\u003e, output voltage, absorption and float settings adjustable to match the connected battery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal protection\u003c\/strong\u003e, automatic power derating under high temperatures.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct overview\u003c\/h2\u003e\u003cp\u003eA high-frequency transformer provides true galvanic isolation between input and output circuits, which matters in marine and vehicle wiring where battery banks share a common chassis ground. Without isolation, charge current can find unintended paths and cause corrosion or interference. This design removes that risk.\u003c\/p\u003e\u003cp\u003eAll setup runs through VictronConnect over Bluetooth: charge algorithm, absorption voltage, float voltage and current limit are all set from a phone or tablet. Engine detection stops the auxiliary bank from draining the starter battery by checking the alternator is actually running before the output switches on.\u003c\/p\u003e\u003cp\u003eAt 240W continuous, this unit tops up a secondary 24V bank during transit rather than bulk charging from flat. Larger Orion-Tr Smart models are available where higher charge rates are needed. The enclosure is compact and can be wall or DIN-rail mounted, suiting tight vehicle cabinets or marine panels.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCharging a 24V auxiliary or leisure battery from a 12V vehicle alternator or starter battery.\u003c\/li\u003e\n\u003cli\u003eMarine dual-battery systems needing galvanic isolation against electrolytic corrosion.\u003c\/li\u003e\n\u003cli\u003eCampervans, motorhomes and commercial vehicles with split 12V\/24V systems.\u003c\/li\u003e\n\u003cli\u003eOff-grid cabins or mobile installations where a 12V source feeds a 24V bank.\u003c\/li\u003e\n\u003cli\u003eTelecommunications and industrial equipment needing a stable, isolated 24V supply from 12V.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1 x Victron Orion-Tr Smart 12\/24-10A (240W) Isolated DC-DC Charger\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFit this with correct cable sizing and fusing on both input and output sides, matched to the rated current.
