It is designed for professional use in off-grid systems, marine and vehicle installations, and any application where two DC bus voltages must be bridged without an electrical connection between them.\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, eliminating ground loop issues and allowing safe integration of separate DC systems.\u003c\/li\u003e\n  \u003cli\u003e24V input to 48V output conversion at 8.5A continuous output current, providing 400W of regulated DC power.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range typical of the Orion-Tr series, accommodating real-world battery voltage fluctuations without shutting down.\u003c\/li\u003e\n  \u003cli\u003eCompact, enclosed metal housing suited to fixed installation in panels, enclosures and vehicle builds.\u003c\/li\u003e\n  \u003cli\u003eFully regulated output voltage, protecting connected 48V loads and battery banks from input-side voltage variation.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron system architectures, including installations monitored via VictronConnect where supported by associated equipment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion-Tr range uses a transformer-based isolated topology, which means the input and output circuits share no direct electrical path. This matters in practice when connecting two battery banks of different voltages, integrating a 48V inverter system with a 24V auxiliary supply, or working in marine environments where galvanic corrosion from ground loops is a genuine concern. The isolation barrier also provides a degree of protection against fault propagation between the two DC systems.\u003c\/p\u003e\n\n\u003cp\u003eAt 400W continuous, this converter is sized for meaningful loads: charging a 48V battery bank from a 24V source, powering 48V inverters or motor controllers from a 24V house bank, or supplying 48V DC distribution in a mixed-voltage system. The regulated output means the 48V side remains stable regardless of normal fluctuations on the 24V input, which is important when the input is a live battery under charge or discharge.\u003c\/p\u003e\n\n\u003cp\u003eThe Orion-Tr series is a well-established product line from Victron Energy, manufactured to consistent quality standards and widely used by professional installers across off-grid, marine, automotive and industrial applications. The isolated variants are the correct choice wherever electrical separation between input and output is a system requirement rather than an option.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border: 2px solid #f87c24; border-collapse: collapse; width: 100%;\"\u003e\n  \u003ctr style=\"background-color: #f87c24; color: #ffffff;\"\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSKU\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eORI244841110\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eInput Voltage (nominal)\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e24V DC\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Voltage (nominal)\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e48V DC\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Current (maximum)\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8.5A\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Power (continuous)\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e400W\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eIsolation\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGalvanic (transformer-based)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eWeight\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e1.52 kg\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGTIN\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8719076038863\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCharging a 48V battery bank from a 24V alternator or battery source in vehicles, boats or off-grid systems.\u003c\/li\u003e\n  \u003cli\u003eSupplying 48V inverters or motor controllers in mixed-voltage DC systems where a 24V primary bus is already established.\u003c\/li\u003e\n  \u003cli\u003eMarine installations requiring galvanic isolation to prevent corrosion caused by ground loops between separate DC systems.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins and mobile setups where two independent battery banks at different voltages must be kept electrically separate.\u003c\/li\u003e\n  \u003cli\u003eIndustrial and telecoms enclosures requiring a stable, regulated 48V rail derived from a 24V supply.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Victron Orion-Tr 24\/48-8.5A (400W) Isolated DC-DC Converter\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 system integrator familiar with DC power systems. Ensure input wiring is correctly fused as close to the source battery as practicable, and that cable sizing is appropriate for the input current at 24V (which will be significantly higher than the 8.5A output current). The galvanic isolation means the output negative does not need to share a common ground with the input negative, but verify your system design before connecting. For marine installations, follow NMEA or flag-state wiring standards as applicable.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863711383886,"sku":"ORI244841110","price":155.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ORI244841110_-_Orion-Tr_24-48-8_5A_400W_Isolated_DC-DC_converter.webp?v=1781183629","url":"https:\/\/voltaconsolar.com\/products\/victron-orion-tr-24-48-8-5a-400w-isolated-dc-dc-converter","provider":"VoltaconSolar","version":"1.0","type":"link"}
