It delivers up to 17A (400W) and is built for dual-battery systems in vehicles, vessels and off-grid installations where electrical isolation between the starter and service battery is required.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e400W output power with a 17A charge current on a 24V to 24V conversion.\u003c\/li\u003e\n  \u003cli\u003eGalvanic isolation between input and output prevents ground loops and protects sensitive electronics.\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 charging algorithm with configurable charge profiles to suit different battery chemistries including lead-acid and lithium.\u003c\/li\u003e\n  \u003cli\u003eRemote on\/off input allows the unit to be controlled by a BMS, ignition switch or other external signal.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range handles fluctuating alternator output without interrupting the charge cycle.\u003c\/li\u003e\n  \u003cli\u003eCompact, wall-mountable enclosure with a 1.8 kg weight suitable for space-constrained installations.\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 (starter battery or alternator circuit) and output (service or auxiliary battery) share no electrical connection. This is particularly important in marine and vehicle installations where ground loops can cause corrosion, interference or damage to electronics. The isolation also allows the unit to be used where the two battery banks have separate negative rails.\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 match the battery chemistry in use. This makes the unit compatible with standard flooded and AGM lead-acid batteries as well as lithium iron phosphate (LiFePO4) packs when used alongside an appropriate BMS. The remote on\/off terminal allows the charger to be disabled when the engine is off, preventing discharge of the starter battery through the converter.\u003c\/p\u003e\n\n\u003cp\u003eThe unit is designed for continuous duty and can be mounted in any orientation. It does not require a fan, relying on its aluminium housing for passive thermal management in most conditions. At 400W it is well suited to topping up a service battery during transit or generator run time in a dual-battery setup.\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;\"\u003eORI242440120\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;\"\u003e24V 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;\"\u003e17A\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eMaximum 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;\"\u003eIsolation\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGalvanic (isolated)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eConnectivity\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eBluetooth (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;\"\u003e8719076047728\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 24V service battery from a 24V vehicle or vessel starter circuit.\u003c\/li\u003e\n  \u003cli\u003eMarine dual-battery systems where galvanic isolation is required to prevent corrosion and ground loops.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and campervan builds with separate chassis and habitation battery banks.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins and mobile installations where a DC source charges an auxiliary battery bank.\u003c\/li\u003e\n  \u003cli\u003eLithium service battery systems requiring a controlled charge profile separate from the alternator output.\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\/24-17A (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 marine electrical engineer familiar with DC systems. Ensure correct cable sizing and fusing on both the input and output sides in accordance with the system current ratings. For lithium battery installations, connect the remote on\/off terminal to the BMS load disconnect output to prevent charging outside safe voltage limits. In marine applications, follow NMEA and flag-state wiring standards where applicable.
