Victron Energy Orion-Tr Smart DC-to-DC Charger 12V-12V 30A (360W) Bluetooth, Three-stage Charging

The Victron Energy Orion-Tr Smart DC to DC Charger (12/12V 30A, 360W) is a three-stage, Bluetooth-enabled charger that safely and efficiently transfers power between alternator/start and service batteries in vehicles and boats.

Compact yet robust, this Orion-Tr Smart unit is designed to manage charging where the alternator and a starter battery supply a separate service battery bank. It supports both lead‑acid and lithium chemistries, offers multiple protection features, and can be monitored or configured wirelessly through the VictronConnect app. With screw‑terminal wiring and parallel stacking capability, it suits installations from simple campervans to more demanding marine or fleet applications.

How does the Orion-Tr Smart ensure batteries charge correctly?

The charger uses a three-stage charging algorithm tailored to battery chemistry and state-of-charge, which helps optimize capacity and longevity without overcharging. Built-in protections guard against common faults so charging remains reliable under varying conditions.

• Multi-stage charge profile: bulk, absorption, float for controlled charging
• Selectable settings for lead‑acid or lithium batteries via Bluetooth
• Protection: thermal, over‑voltage, and reverse‑polarity safeguards

Can I monitor and adjust the charger remotely?

Yes — integrated Bluetooth pairs with VictronConnect on smartphones and tablets to show live status and let you change settings. Wireless access removes the need to physically access the unit for most configuration or troubleshooting tasks.

• Wireless readout of voltage, current, and charge state
• Adjust charge profiles and limits from the app
• Firmware updates and diagnostics via Bluetooth

What installation and expansion options are available?

Installation is simplified with screw terminals that accept standard wiring and connectors; no specialized tooling is necessary. Multiple units can be linked in parallel to scale output for larger battery banks or higher charging currents.

• Screw‑terminal connections for straightforward wiring
• Parallelable: combine units to increase total output power
• Compact footprint fits behind panels or in engine bays with ventilation

Is this charger suitable for my vehicle or boat setup?

The Orion‑Tr Smart is intended for systems where an alternator or starter battery charges a separate service battery, common in leisure vehicles, boats, and work vehicles. It's adaptable to most 12V systems and supports modern lithium packs as well as conventional lead‑acid batteries.

• Works with 12V alternator-to-service battery configurations
• Configured for lead‑acid (including AGM/GEL) and lithium chemistries
• Durable construction for mobile and marine environments

Who is this for: The Victron Energy Orion-Tr Smart 12/12V 30A charger is aimed at DIY installers, professional upfitters, and boat owners who need a dependable, configurable DC‑to‑DC charging solution. It fits users who want Bluetooth monitoring, flexible battery compatibility, and the ability to scale charging capacity for larger systems — ideal for campervan conversions, commercial vans, leisure boats, and hybrid power installations.
