It is built for vehicles, boats and off-grid installations where a starter battery and a service battery must be kept electrically separate. The unit is Bluetooth-enabled and integrates with the VictronConnect app for configuration and monitoring.\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\u003e30A output current at 12V delivers up to 360W of continuous charge power to the service battery.\u003c\/li\u003e\n  \u003cli\u003eBuilt-in Bluetooth allows full configuration and real-time monitoring via the VictronConnect app on iOS and Android, without additional hardware.\u003c\/li\u003e\n  \u003cli\u003eAdaptive multi-stage charging algorithm (bulk, absorption, float) ensures correct charge profiles for lead-acid and lithium battery chemistries.\u003c\/li\u003e\n  \u003cli\u003eEngine detection via input voltage threshold prevents discharging the starter battery when the alternator is not running.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range accommodates real-world alternator voltage fluctuations and varying battery states.\u003c\/li\u003e\n  \u003cli\u003eCompact, sealed enclosure rated for installation in engine bays and other demanding environments.\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 high-frequency transformer to provide full galvanic isolation between the input (alternator\/starter battery) and output (service\/leisure battery). This is particularly important in marine and vehicle installations where shared grounds can cause corrosion, interference or safety issues. The isolation also means the unit can be used to charge a battery bank at a different voltage potential without risk of cross-circuit faults.\u003c\/p\u003e\n\n\u003cp\u003eUnlike simple voltage-sensitive relays (VSRs) or DC-DC converters without charge management, the Orion-Tr Smart applies a proper multi-stage charge profile. This matters for lithium batteries in particular, where a flat absorption stage and accurate voltage thresholds are required to avoid undercharging or triggering battery management system shutdowns. The engine detection feature uses the input voltage level to determine whether the alternator is active, preventing the unit from drawing down the starter battery when the engine is off.\u003c\/p\u003e\n\n\u003cp\u003eVictronConnect integration gives installers full control over charge voltages, absorption time, battery type presets and engine detection thresholds. All settings are adjustable over Bluetooth without opening the unit or accessing the installation location, which is a practical advantage in tight or awkward installations.\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  \u003cthead\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  \u003c\/thead\u003e\n  \u003ctbody\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;\"\u003eORI121236120\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;\"\u003e12V 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;\"\u003e12V DC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Current (max)\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e30A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Power (max)\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e360W\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;\"\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;\"\u003e8719076047698\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCharging a lithium leisure battery from a vehicle alternator while keeping the starter battery isolated.\u003c\/li\u003e\n  \u003cli\u003eMarine dual-battery installations where galvanic isolation is required to prevent corrosion and ground loops.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and campervan builds with separate starter and habitation battery banks.\u003c\/li\u003e\n  \u003cli\u003eOff-grid vehicles and expedition rigs where reliable service battery charging from the alternator is critical.\u003c\/li\u003e\n  \u003cli\u003eCommercial vehicle auxiliary power systems requiring a managed, isolated charge source.\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 12\/12-30A Isolated DC-DC Charger (ORI121236120)\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 marine\/vehicle electrician familiar with DC power systems.
