Detailed description

Designed for dual-battery systems onboard, the Victron Energy Orion Tr Smart 12/12-18A (220W) isolated DC-DC charger provides a stable charging and power supply solution. It handles input voltages from 8 to 17V and delivers a nominal 12.2V output, adjustable from 10 to 15V. Its continuous 18A capacity at 40°C, with a power output of 220W (280W at 25°C), ensures efficient charging of service batteries with an efficiency of 87%. This model features 200 VDC galvanic isolation between input, output, and case, a critical safety feature for marine installations and vehicles.

Compatibility and smart features

Compatibility with smart alternators (Euro 5 and Euro 6) via engine-running detection prevents discharge of the starter battery when the alternator is not supplying power. The charger uses a three-stage adaptive charging algorithm (bulk, absorption, float) to optimize battery lifespan, whether lead-acid or lithium. Absorption time is adjustable via VictronConnect, offering flexibility for different battery types. Integrated Bluetooth Smart connectivity, via the VictronConnect app, provides full control over charging parameters and real-time monitoring. Features like input voltage lock and remote on/off increase integration flexibility.

System integration and protection

For higher current needs, an unlimited number of Orion Tr Smart units can be connected in parallel, enabling system scalability. The charger is protected against overload, short circuits, high temperatures (with automatic power reduction above 40°C), and connector overheating, ensuring reliable operation. Its IP43 protection rating for electronic components and IP22 for the connection area provides adequate resistance to marine environments. Compared to non-isolated DC-DC converters in the Orion range, this isolated model offers enhanced safety by preventing ground loops and protecting sensitive equipment from electrical disturbances, which is particularly relevant in complex marine environments. While other Victron Energy chargers like the Blue Smart IP65 are AC chargers, the Orion Tr Smart manages charging between two DC batteries, addressing a specific need for onboard systems where stable DC power or auxiliary charging is required.

« Isolated DC-DC charger Victron Orion Tr Smart: DC management for embedded systems »

The Victron Energy Orion Tr Smart 12/12-18A isolated charger is a technical solution for onboard power management, particularly suited to modern vehicles equipped with smart alternators (Euro 5/6) and marine installations where galvanic isolation is mandatory. Its ability to operate in three-stage adaptive charging mode or stable power supply mode makes it a versatile component for dual-battery systems.

We recommend this model for sailboats, motorhomes, and expedition vehicles requiring a service battery to be charged from a starter battery or engine bank without affecting sensitive electronics. The integration of Bluetooth Smart and the VictronConnect app simplifies the configuration of voltage thresholds for engine running detection, eliminating the need for external sensors and ensuring the charger does not draw from the starter battery when the engine is off. The option to connect multiple units in parallel is a significant advantage for installations requiring higher charging currents without complicating wiring or management.

While robust, it is critical to follow cable cross-section recommendations (up to 16mm² or 6AWG) and install appropriate fuses at the input and output to prevent overheating risks. Vertical installation with terminals facing downward and a 10 cm clearance above and below is essential for heat dissipation, especially during continuous full-power operation when the device may reach high temperatures. For high-power systems, consider the Orion-Tr Smart range with higher power ratings or adding units in parallel rather than overloading a single unit.

What is the primary role of the Victron Orion Tr Smart 12/12-18A DC-DC charger?

The Orion Tr Smart DC-DC charger can be used as a power supply or as a battery charger. In charger mode, it uses a three-stage charging algorithm to extend battery life, which is particularly useful for vehicles equipped with smart alternators. It also protects the alternator in lithium systems.

What is the input and output voltage of this DC-DC charger?

This charger accepts input voltages from 8 to 17V. Its nominal output voltage is 12.2V, adjustable from 10 to 15V. It is designed for 12V systems with 12V input and output.

What is the maximum output power and current of this charger?

The charger delivers a continuous output current of 18A at 40°C. Its power output is 220W at 40°C and can reach 280W at 25°C.

Is the Orion Tr Smart charger compatible with smart alternators?

Yes, this charger is compatible with smart alternators (Euro 5 and Euro 6). It includes an engine-running detection mechanism that prevents it from discharging the starter battery when the alternator is not supplying power, which is critical with these systems.

How does the charger handle engine-running detection?

The charger has built-in engine-running detection. This function allows the charger to supply power only when the engine is running, preventing the starter battery from discharging and reducing the risk of the vehicle voltage dropping too low. No intervention on the vehicle system or installation of a separate engine-running sensor is required.

What type of charging algorithm does this charger use?

The Orion Tr Smart charger uses a three-stage adaptive charging algorithm: Bulk (rapid charge), Absorption (constant voltage), and Float (trickle charge). The absorption duration is automatically adjusted for lead-acid batteries and is fixed for lithium batteries, but can be configured via VictronConnect.

Can this charger recharge lead-acid and lithium batteries?

Yes, the Orion Tr Smart charger is compatible with lead-acid and lithium batteries. The adaptive charging algorithm can be programmed to suit different battery types, and the absorption time is adjustable via the VictronConnect app to optimize charging.

How can I configure and monitor the Orion Tr Smart charger?
