« Technical analysis of the Orion Tr Smart isolated DC-DC charger 24/24-12A »

The Victron Energy Orion Tr Smart 24/24-12A (280W) isolated DC-DC charger represents a technically relevant solution for modern marine and mobile installations. Its main strength lies in its 200V DC galvanic isolation, essential for preventing ground loops and ensuring safe electrical separation between two 24V systems, particularly in setups where grounds must be strictly distinct.

This battery charger-converter is particularly suited to vehicles and boats equipped with smart alternators (Euro 5/6 standards) thanks to its engine-running detection mechanism. This feature eliminates the need for external sensors or complex wiring modifications in the vehicle, greatly simplifying integration. The three-stage adaptive charging algorithm is a direct advantage for battery longevity, whether using lead-acid or lithium batteries, by optimizing charge cycles. Bluetooth connectivity via VictronConnect facilitates precise charge parameter configuration and real-time monitoring, a major asset for installers and experienced users.

In terms of installation, screw terminals simplify wiring, but careful attention must be paid to cable sizing for a 12A DC current. Vertical mounting with a 10 cm clearance is critical for effective thermal dissipation, given that the device can heat up during maximum operation. While the 280W model is sufficient for moderate charging needs, for larger battery banks or fast charging, connecting multiple units in parallel is a viable solution to increase total output power. It is important to note that this model is not designed for full immersion environments, its IP43 rating being suitable for water spray when correctly mounted.

What is the Orion Tr Smart 24/24-12A (280W) DC-DC isolated charger?

The Victron Energy Orion Tr Smart 24/24-12A (280W) isolated DC-DC charger is a professional converter and charger designed for dual-battery systems onboard. It can recharge a service battery from an alternator or a starter battery, or function as a fixed-voltage power supply. It provides 200V DC galvanic isolation between the input, output, and housing.

What are the main performance characteristics of this charger?

This charger delivers continuous power of 280W at 40°C (320W at 25°C) and a continuous output current of 12A at 40°C. Its efficiency reaches 89%. It can operate within a temperature range of -20 to +55°C.

What is the input and output voltage range of the charger?

The Orion Tr Smart 24/24-12A charger has an input voltage range of 16-35V and an adjustable output voltage of 20-30V, with a nominal voltage of 24.2V.

Is the charger protected against overloads or short circuits?

Yes, the charger includes multiple electronic protections, including against high temperatures, overcharging, short circuits, and overheated connectors.

What is the function of the integrated Bluetooth Smart?

The integrated Smart Bluetooth enables monitoring, configuration, and software updates of the charger via the VictronConnect app, available on smartphones or tablets.

How does the battery charging algorithm work?

The charger uses a 3-stage adaptive charging algorithm: bulk (fast charge), absorption (constant voltage with adjusted duration), and float (float charge). The absorption time is automatically adjusted for lead-acid batteries and is fixed at 2 hours by default for lithium batteries.

Can the charger operate as a fixed-voltage power supply?

Yes, in power mode, the output voltage remains stable, regardless of the load applied or input voltage variations (within the specified range).

What is the engine running detection function?

The engine running detection function allows the charger to supply power only when the vehicle's engine is running. This prevents the starter battery from discharging when the alternator is not providing current and does not require any intervention in the vehicle's system.

What is the water and dust protection rating of this charger?

The charger has IP43 protection when installed with the screw terminals facing downward. This means it is protected against solid objects larger than 1 mm and against water splashes.

Is the charger galvanically isolated?

Yes, the Orion Tr Smart 24/24-12A charger provides 200V DC galvanic isolation between the input, output, and case, improving the electrical safety of the system.

How should the Orion Tr Smart charger be installed?

The charger must be mounted vertically on a non-flammable surface, with the power terminals facing downward. It is important to leave a minimum clearance of 10 cm above and below the unit for optimal cooling.

Where should the charger not be installed?

Never mount the charger directly above the battery to avoid damage from battery gases. It must be installed near the battery, but not directly on it.

Which types of cables and fuses are recommended for the installation?

For battery connections, use flexible multi-strand copper cables. The diameter of individual strands must not exceed 0.4 mm or 0.125 mm² (AWG26). A fuse must be included in the installation in accordance with the product manual's recommendations.

What is the recommended cable size for this charger?

The manual recommends a 16mm² cable with at least 122 strands (class 5 or higher per VDE 0295, IEC 60228, and BS6360), such as a "Tri-rated" class 5 cable. Using strands that are too thick can lead to high contact resistance and overheating.

Is the charger protected against reverse polarity during installation?

No, the product is not protected against reverse polarity. It is critical to check polarity before and during battery connection to avoid damaging the device.

How to remotely enable or disable the charger?

The charger can be turned on or off remotely via the remote on/off connector or via the VictronConnect app. This allows use cases such as a wired switch or automatic control by a battery management system (BMS).

Is this charger compatible with smart alternators?

Yes, the Orion Tr Smart charger is compatible with smart alternators (ECU-controlled) that provide a variable output voltage and can shut down when not required. It includes an engine-running detection mechanism to prevent draining the starter battery.

Can the charger be used with lithium batteries?

Yes, the charger is compatible with lithium batteries. Its 3-stage adaptive charging algorithm adjusts the absorption time, which is set to 2 hours by default for lithium batteries.

Can the charger be configured for different battery types?

Yes, the charger has a programmable charging algorithm and eight pre-programmed battery settings, configurable via the VictronConnect app to adapt to different battery types.

Is it possible to use this charger to separate the starter battery from the service battery?

Yes, the Orion-Tr Smart DC-DC Charger is designed to isolate the starter battery and the service battery when the engine is not running, ensuring the starter battery is not discharged.
