Orion-Tr Smart 24/12-20A Isolated DC-DC charger

The Orion-Tr Smart 24/12-20A Isolated DC-DC Charger from Victron Energy is an advanced charger that allows you to efficiently charge your hotel battery directly from the main battery in the engine compartment. By limiting the charging current to 20A, it protects the hotel battery from overload, allowing for safe use and extending battery life.

High performance and dual-battery support

The device is designed for use in vehicles and boats, where two batteries—a starter and a guest—work together in a system managed by the alternator. Orion-Tr Smart allows you to charge the service battery without the risk of overheating or overcharging, ensuring stable operation of the entire system.

Bluetooth connectivity and remote management

The charger is equipped with a Bluetooth module, enabling full control and monitoring of the device via the VictronConnect app. This allows users to remotely control the charger, adjust parameters, and monitor system status without requiring direct access to the device.

Hotel Battery Protection and Energy Management

Orion-Tr Smart manages the charging current by automatically controlling its intensity, protecting the hotel battery from overload. The device ensures smooth and safe charging by adapting operating parameters to current conditions, preventing overcharging and extending battery life.

Automatic engine operation detection

The Orion-Tr Smart charger features automatic engine run detection. When the vehicle is stopped, the charger automatically shuts off to prevent discharging the starter battery, ensuring greater system reliability.
