Victron Orion-Tr Smart 48/24-16A DC-DC Charging Booster, 380W, Isolated

The Victron Orion-Tr Smart 48/24-16A (MPN: ORI482438120) is an isolated DC-DC charge booster for the controlled charging of a 24 V service battery from a 48 V system. It delivers 16 A of charging current and 380 W of continuous output power at 40 °C. Charging parameters and operating data can be configured and monitored via Bluetooth using the VictronConnect app.

Controlled charging from 48 to 24 volts

• Galvanic isolation with 200 VDC between input, output, and housing
• Adaptive three-stage charging algorithm for lead-acid and lithium batteries
• Eight preconfigured battery profiles
• Remote on/off control
• Integrated motor shutdown detection
• Charger and power supply modes
• Multiple devices can be connected in parallel
• Over-temperature, overload, and short-circuit protection
• Configuration and monitoring via Bluetooth and VictronConnect

Adaptive charging method for 24 V batteries

In charger mode, it operates with three charging stages: constant current, constant voltage, and trickle charge. The duration of the constant-voltage stage can be adaptively adjusted based on the previous charging history. Eight preconfigured profiles are available for various lead-acid and lithium batteries. The charging parameters can be adjusted according to the battery manufacturer’s specifications.

Galvanically Isolated Input and Output

The input, output, and housing are galvanically isolated from each other at 200 VDC. This ensures that the 48 V input system and the connected 24 V output system remain electrically separate. This voltage combination is particularly suitable for systems in which a 24 V service battery is to be charged from a 48 V DC source.

Bluetooth Configuration with VictronConnect

The integrated Bluetooth interface enables configuration and monitoring via the VictronConnect app. The charging profile, charging voltages, input voltage lockout, and engine shutdown detection can be adjusted there. Alerts and device statuses are also available. The app does not display input or output current for this model. A VE.Direct connection is not available.

Installation and Connection Instructions

The charge booster must be mounted vertically on a non-flammable surface, with the power terminals facing downward. To ensure adequate cooling, at least 10 cm of clearance is required above and below the unit. Avoid mounting it directly above a battery. It is not reverse-polarity protected. Before connecting, therefore, check the polarity of the input and output sides as well as the suitability of the battery profile being used. The installation requires external battery fuses and copper cables suitable for the respective cable lengths.
