It is aimed at professional installers working on vehicles, vessels and off-grid systems where electrical isolation between battery banks is a requirement, not an option.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eGalvanic isolation between input and output eliminates ground loop issues and protects sensitive electronics on both battery banks.\u003c\/li\u003e\n  \u003cli\u003e240W continuous output at 20A on the 12V side, suitable for maintaining or charging a secondary battery bank from a 24V source.\u003c\/li\u003e\n  \u003cli\u003eBuilt-in Bluetooth allows configuration and monitoring via the VictronConnect app on iOS and Android, without additional hardware.\u003c\/li\u003e\n  \u003cli\u003eTwo-wire engine detection senses alternator output and automatically switches between storage and absorption charge modes to protect the starter battery.\u003c\/li\u003e\n  \u003cli\u003eAdaptive charging algorithm with configurable charge profiles to suit AGM, gel, lithium and other battery chemistries.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range handles real-world voltage fluctuations from alternators and solar-charged battery banks.\u003c\/li\u003e\n  \u003cli\u003eCompact, wall-mountable enclosure with a weight of 1.3 kg, suited to installations with limited space.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion-Tr Smart uses a DC-DC conversion stage with full galvanic isolation, meaning the input and output circuits share no common ground. This matters in dual-battery vehicle and marine installations where a shared ground can cause corrosion, interference or fault currents. The isolation also means the unit can be used to step voltage down from 24V to 12V while keeping the two battery systems electrically independent.\u003c\/p\u003e\n\n\u003cp\u003eThe two-wire engine detection input is a practical feature for alternator-based charging. When the alternator is running, the unit charges at the programmed absorption or bulk rate. When the engine stops, it drops to a lower storage voltage to avoid draining the starter battery. This behaviour is configurable via VictronConnect, where installers can also set charge voltages, absorption time and tail current to match the connected battery chemistry.\u003c\/p\u003e\n\n\u003cp\u003eVictronConnect Bluetooth is built in, so there is no need for a separate dongle or interface. Installers can commission the unit, adjust parameters and check live data directly from a phone or tablet. The Orion-Tr Smart is also compatible with the Victron VE.Direct ecosystem for integration into larger monitoring setups where required.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ORI241224120\u003c\/li\u003e\n  \u003cli\u003eInput voltage: 24V DC (nominal)\u003c\/li\u003e\n  \u003cli\u003eOutput voltage: 12V DC (nominal)\u003c\/li\u003e\n  \u003cli\u003eOutput current: 20A\u003c\/li\u003e\n  \u003cli\u003eOutput power: 240W\u003c\/li\u003e\n  \u003cli\u003eIsolation: Galvanic (isolated DC-DC)\u003c\/li\u003e\n  \u003cli\u003eConnectivity: Bluetooth (VictronConnect), two-wire engine detection\u003c\/li\u003e\n  \u003cli\u003eWeight: 1.3 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076046080\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-battery systems in campervans, motorhomes and HGVs with a 24V chassis and a 12V leisure battery bank.\u003c\/li\u003e\n  \u003cli\u003eMarine installations requiring galvanic isolation between the engine 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 for lighting or accessories.\u003c\/li\u003e\n  \u003cli\u003eLithium battery upgrades where a controlled, chemistry-specific charge profile is needed for the secondary bank.\u003c\/li\u003e\n  \u003cli\u003eProfessional vehicle conversions where ground loop elimination is required to protect 12V electronics.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Victron Orion-Tr Smart 24\/12-20A (240W) Isolated DC-DC Charger\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eInstallation should be carried out by a qualified electrician or experienced installer familiar with DC battery systems. Correct cable sizing and fusing on both the input and output sides is essential at these current levels. For marine installations, follow applicable wiring standards and ensure the unit is mounted in a ventilated location away from direct water ingress. The two-wire engine detection input must be wired to a switched 24V supply that is live only when the engine is running. Lithium battery profiles should be confirmed against the battery manufacturer's specifications before commissioning.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863717052750,"sku":"ORI241224120","price":123.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ORI241224120_-_Orion-Tr_Smart_24-12-20A_240W_Isolated_DC-DC_charger.webp?v=1781183663","url":"https:\/\/voltaconsolar.com\/products\/victron-orion-tr-smart-24-12-20a-240w-isolated-dc-dc-charger","provider":"VoltaconSolar","version":"1.0","type":"link"}
