It is designed for professional dual-battery and multi-voltage DC systems where electrical isolation between source and load is a hard requirement. Bluetooth configuration and monitoring are built in, with no additional hardware needed.\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 loads from input-side faults.\u003c\/li\u003e\n  \u003cli\u003e400W continuous output power with an 8.5A charge current at 48V nominal output.\u003c\/li\u003e\n  \u003cli\u003eInput voltage range of 24V nominal, with a wide acceptance window suitable for real-world battery and alternator voltage variation.\u003c\/li\u003e\n  \u003cli\u003eBuilt-in Bluetooth connectivity allows configuration and live monitoring via the VictronConnect app on iOS and Android, with no dongle required.\u003c\/li\u003e\n  \u003cli\u003eAdaptive charging algorithm supports lithium (LiFePO4) and lead-acid battery chemistries, with configurable charge profiles.\u003c\/li\u003e\n  \u003cli\u003eEngine detection function prevents excessive discharge of the starter battery by monitoring input voltage and only charging when the alternator is running.\u003c\/li\u003e\n  \u003cli\u003eRemote on\/off control via a dedicated terminal, suitable for integration with battery management systems and external switching.\u003c\/li\u003e\n  \u003cli\u003eCompact, fully enclosed aluminium housing rated for permanent installation in vehicles, vessels and off-grid enclosures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion-Tr Smart series uses a high-frequency transformer to provide full galvanic isolation between the DC input and output. This is particularly important in marine and vehicle installations where chassis grounds from two separate battery banks must not be connected, and where ground loops can cause corrosion, interference or damage to electronics. The isolation also means the unit can be used to step voltage up from a 24V source bank to charge a separate 48V service or traction battery without any shared ground path.\u003c\/p\u003e\n\n\u003cp\u003eConfiguration is handled entirely through the VictronConnect app over Bluetooth. Charge voltage, absorption time, float voltage and tail current can all be adjusted to match the target battery chemistry. The engine detection feature uses input voltage thresholds to determine whether the vehicle or vessel alternator is active, preventing the unit from drawing down the starter battery when the engine is off. This makes it suitable for split-charge applications where protecting the cranking battery is essential.\u003c\/p\u003e\n\n\u003cp\u003eAt 400W continuous, this unit is well suited to applications where a moderate charge current is needed between two voltage domains, such as charging a 48V lithium house bank from a 24V alternator system, or maintaining a 48V auxiliary battery from a 24V primary supply. The unit can be paralleled with additional Orion-Tr Smart units if higher charge currents are required.\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;\"\u003eORI244840120\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;\"\u003eMaximum Output Current\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;\"\u003eContinuous Output Power\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;\"\u003eGalvanic Isolation\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eYes\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eBluetooth\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eBuilt-in (VictronConnect)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eRemote On\/Off\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eYes\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;\"\u003e1.8 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;\"\u003e8719076065579\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 lithium or lead-acid house battery from a 24V alternator or starter battery bank on commercial vehicles and HGVs.\u003c\/li\u003e\n  \u003cli\u003eMarine dual-battery systems where galvanic isolation is required to prevent corrosion and ground loop interference.\u003c\/li\u003e\n  \u003cli\u003eOff-grid and mobile installations with mixed-voltage DC architectures requiring isolated voltage conversion.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and coach builds where a 48V auxiliary system is fed from a 24V chassis electrical system.\u003c\/li\u003e\n  \u003cli\u003eIndustrial and telecoms backup systems requiring isolated DC-DC conversion between voltage domains.\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 Smart 24\/48-8.5A (400W) 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 DC systems installer.
