It delivers up to 12A (280W) of charge current and is managed via Bluetooth, making it well suited to vehicles, marine installations and off-grid systems where a starter battery must be kept separate from a service or leisure battery.\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 in dual-battery installations.\u003c\/li\u003e\n  \u003cli\u003eBuilt-in Bluetooth allows configuration and monitoring via the VictronConnect app on iOS and Android, with no additional hardware required.\u003c\/li\u003e\n  \u003cli\u003eAdaptive 3-stage charging algorithm (bulk, absorption, float) conditions the output battery properly rather than simply maintaining a fixed voltage.\u003c\/li\u003e\n  \u003cli\u003eInput voltage range accommodates real-world 24V system voltages, including those with engine-running alternator boost.\u003c\/li\u003e\n  \u003cli\u003eEngine detection function prevents excessive drain on the starter battery by only charging when the alternator is active.\u003c\/li\u003e\n  \u003cli\u003eCompact, wall-mountable enclosure weighing 1.3kg suits installations with limited space.\u003c\/li\u003e\n  \u003cli\u003eConfigurable charge profiles allow the unit to be matched to AGM, gel, lithium (LiFePO4) and other battery chemistries.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion-Tr Smart range differs from basic DC-DC converters by incorporating a full battery charging algorithm rather than simply stepping voltage up or down. At 280W output, the 24\/24-12A variant is capable of maintaining a 24V service battery from a 24V vehicle or vessel electrical system without the two battery banks sharing a common ground. The galvanic isolation is particularly important in marine environments, where stray current corrosion is a genuine risk, and in any installation where the chassis grounds of two systems must remain independent.\u003c\/p\u003e\n\n\u003cp\u003eConfiguration is handled entirely through VictronConnect over Bluetooth. Charge voltage, absorption time, float voltage and tail current can all be adjusted to suit the battery chemistry on the output side. The engine detection feature monitors input voltage and only enables charging once the alternator raises the bus voltage above a user-defined threshold, protecting the starter battery from being discharged by the service bank when the engine is off.\u003c\/p\u003e\n\n\u003cp\u003eThe unit can also be used in a load output mode, acting as a stabilised 24V supply rather than a charger, which broadens its application beyond simple battery-to-battery charging. It is compatible with the Victron VE.Smart networking ecosystem, allowing it to share battery voltage and temperature data with other Victron devices on the same Bluetooth network for coordinated charging.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ORI242428120\u003c\/li\u003e\n  \u003cli\u003eInput voltage: 24V DC nominal\u003c\/li\u003e\n  \u003cli\u003eOutput voltage: 24V DC nominal\u003c\/li\u003e\n  \u003cli\u003eMaximum output current: 12A\u003c\/li\u003e\n  \u003cli\u003eMaximum output power: 280W\u003c\/li\u003e\n  \u003cli\u003eIsolation: Galvanic (isolated DC-DC)\u003c\/li\u003e\n  \u003cli\u003eCommunication: Bluetooth (VictronConnect)\u003c\/li\u003e\n  \u003cli\u003eWeight: 1.3kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076046097\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 24V commercial vehicles, HGVs and campervans where starter and service batteries must remain electrically isolated.\u003c\/li\u003e\n  \u003cli\u003eMarine installations requiring galvanic isolation to prevent stray current corrosion between hull and battery systems.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins and mobile setups where a 24V house bank is charged from a 24V vehicle or generator feed.\u003c\/li\u003e\n  \u003cli\u003eTelecom and industrial equipment requiring a stable, isolated 24V supply derived from a 24V bus.\u003c\/li\u003e\n  \u003cli\u003eLithium service battery installations where a dedicated charge profile is required and isolation from the alternator circuit is necessary.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eVictron Orion-Tr Smart 24\/24-12A isolated DC-DC charger (1 unit)\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 12\/24V systems installer. Ensure correct cable sizing and fusing on both the input and output sides in accordance with the unit's rated current. In marine applications, follow BMEA or equivalent wiring standards. The unit must be mounted in a ventilated location away from direct water ingress. For lithium battery outputs, verify that the charge profile is correctly configured in VictronConnect before commissioning. This unit is not grid-connected and does not require G98 or G99 compliance, but any wider system integration should be reviewed by a competent person.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59856060678478,"sku":"ORI242428120","price":123.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ORI242428120_-_Orion-Tr_Smart_24-24-12A_280W_Isolated_DC-DC_charger.webp?v=1781102033","url":"https:\/\/voltaconsolar.com\/products\/victron-orion-tr-smart-24-24-12a-280w-isolated-dc-dc-charger","provider":"VoltaconSolar","version":"1.0","type":"link"}
