It suits installers working on vehicles, vessels and off-grid systems where electrical isolation between battery banks is required.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolation\u003c\/strong\u003e, galvanic isolation between input and output, removing shared ground between the two battery banks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e, 240W continuous output at 20A on the 12V side.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth\u003c\/strong\u003e, built-in Bluetooth for configuration and monitoring via the VictronConnect app on iOS and Android.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine detection\u003c\/strong\u003e, two-wire engine detection senses alternator output and switches between storage and absorption charge modes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharge profiles\u003c\/strong\u003e, adaptive charging algorithm with configurable profiles for AGM, gel, lithium and other chemistries.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e, 1.3 kg in a wall-mountable enclosure.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow it works\u003c\/h2\u003e\u003cp\u003eInput and output circuits share no common ground, which matters in dual-battery vehicle and marine installations where a shared ground can cause corrosion, interference or fault currents. The isolation also lets the unit step voltage down from 24V to 12V while keeping the two systems electrically independent.\u003c\/p\u003e\u003cp\u003eThe two-wire engine detection input charges at the programmed absorption or bulk rate while the alternator runs, then drops to a lower storage voltage once the engine stops, protecting the starter battery. Charge voltages, absorption time and tail current are all configurable in VictronConnect, and the built-in Bluetooth means no separate dongle is needed to commission or monitor the unit. It also works within the Victron VE.Direct ecosystem for larger monitoring setups.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDual-battery systems in campervans, motorhomes and HGVs with a 24V chassis and a 12V leisure bank.\u003c\/li\u003e\n\u003cli\u003eMarine installations needing galvanic isolation between the start battery and the service bank.\u003c\/li\u003e\n\u003cli\u003eOff-grid cabins and vehicles where a 24V primary bank feeds a 12V secondary system.\u003c\/li\u003e\n\u003cli\u003eLithium battery upgrades needing a chemistry-specific charge profile.\u003c\/li\u003e\n\u003cli\u003eVehicle conversions where ground loop elimination protects 12V electronics.\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 24\/12-20A (240W) Isolated DC-DC Charger\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFit this with correctly sized cable and fusing on both input and output sides. In marine installations, mount in a ventilated location away from water ingress and follow applicable wiring standards. The two-wire engine detection input must be wired to a switched 24V supply that is live only when the engine runs. Confirm lithium charge profiles against the battery manufacturer's specifications before commissioning.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52095396053280,"sku":"ORI241224120","price":123.27,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-ori241224120-1.webp?v=1785748544","url":"https:\/\/www.ledandsolar.co.uk\/products\/orion-tr-smart-isolated-dc-dc-charger","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
