It is suited to professional vehicle, marine and off-grid installations where two 24V battery banks need to be managed independently without galvanic isolation between them. 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\u003e400W continuous output power at 17A on a 24V output, suitable for charging auxiliary battery banks efficiently from a 24V source.\u003c\/li\u003e\n  \u003cli\u003eNon-isolated design: shares a common ground between input and output, making it appropriate where galvanic isolation is not required.\u003c\/li\u003e\n  \u003cli\u003eBuilt-in Bluetooth with VictronConnect app support for remote configuration, monitoring and firmware updates without additional hardware.\u003c\/li\u003e\n  \u003cli\u003eAdaptive charging algorithm with selectable battery presets including lithium, AGM, gel and flooded lead-acid.\u003c\/li\u003e\n  \u003cli\u003eEngine-running detection via input voltage threshold, preventing discharge of the starter battery when the alternator is not active.\u003c\/li\u003e\n  \u003cli\u003eTwo-wire BMS connection support, allowing the charger to be enabled or disabled directly by a lithium BMS.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range accommodates fluctuating vehicle or system supply voltages without interruption to output.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion-Tr Smart non-isolated range is built for dual-battery installations where both banks share the same nominal voltage and a common ground connection is acceptable. In a 24V-to-24V configuration, the charger takes power from the primary supply (typically connected to the alternator or main battery) and delivers a properly regulated charge profile to the secondary battery. This matters because a direct parallel connection between two batteries of different states of charge causes uncontrolled current flow, which can damage batteries and stress alternators. The Orion-Tr Smart prevents this by acting as a controlled current source with a defined charge curve.\u003c\/p\u003e\n\n\u003cp\u003eBluetooth configuration via VictronConnect means there is no need for a separate display or programming interface on the vehicle or vessel. Charge parameters, input voltage thresholds and battery type can all be set from a phone or tablet. The two-wire BMS port is particularly relevant for lithium battery installations: when the BMS signals that the battery is full or has a fault, it can cut the charger output directly without requiring additional relays or control wiring.\u003c\/p\u003e\n\n\u003cp\u003eThe non-isolated version is lighter and more compact than the isolated equivalent, which makes it a practical choice where space and weight are a consideration and where the electrical architecture of the installation does not require separation of the two battery circuits. Installers should confirm the grounding arrangement of the system before selecting this unit over the isolated variant.\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;\"\u003eORI242440140\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;\"\u003eOutput 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;\"\u003eOutput 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;\"\u003eNon-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;\"\u003eBMS Connection\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eTwo-wire BMS port\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;\"\u003e8719076048985\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 auxiliary or habitation battery from a 24V vehicle or truck starter battery circuit.\u003c\/li\u003e\n  \u003cli\u003eMarine dual-battery systems where both banks operate at 24V and share a common ground.\u003c\/li\u003e\n  \u003cli\u003eOff-grid vehicles, motorhomes and expedition builds with 24V lithium or lead-acid auxiliary battery banks.\u003c\/li\u003e\n  \u003cli\u003eCommercial vehicle conversions requiring controlled alternator-based charging of a secondary battery.\u003c\/li\u003e\n  \u003cli\u003eTelecom or industrial equipment installations with separate 24V supply and load battery circuits.\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\/24-17A (400W) Non-Isolated DC-DC Charger (ORI242440140)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis unit should be installed by a qualified electrician or experienced system integrator familiar with DC vehicle or marine electrical systems. The non-isolated design means input and output share a common ground; verify that this is compatible with the grounding scheme of your installation before fitting. Ensure input and output wiring is correctly rated for the current involved and that appropriate fusing is fitted on both the input and output circuits as close to the battery terminals as practicable. For lithium battery installations, connect the two-wire BMS port to allow the BMS to control charger operation. Configure the unit via VictronConnect before commissioning.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59856060711246,"sku":"ORI242440140","price":158.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ORI242440140_-_Orion-Tr_Smart_24-24-17A_400W_Non-isolated_DC-DC_charger.webp?v=1781102038","url":"https:\/\/voltaconsolar.com\/products\/victron-orion-tr-smart-24-24-17a-400w-non-isolated-dc-dc-charger","provider":"VoltaconSolar","version":"1.0","type":"link"}
