Orion-Tr Smart 24/12-30A Isolated DC-DC charger

The Orion-Tr Smart 24/12-30A Isolated DC-DC Charger from Victron Energy is a modern charger designed to charge a hotel battery from the main vehicle or boat battery. By limiting the charging current to 30A, the device ensures the safety of the hotel battery by protecting it from overcharging, which translates into longer battery life.

Performance and reliability

The Orion-Tr Smart 24/12-30A is a DC-to-DC charger that features a three-stage charging process, ensuring optimal charging of the hotel battery without the risk of overheating or overloading. It's ideal for dual-battery systems, which are common in vehicles and boats.

Bluetooth remote control

Thanks to the built-in Bluetooth module, the Orion-Tr Smart charger can be monitored and programmed remotely using the VictronConnect app. This feature allows the user to fully control the device and adjust operating parameters to current needs, without requiring physical access to the device.

Battery protection and safety

The device is equipped with a charging current management system that prevents overloading, protecting the hotel battery from charging too quickly. Additionally, Orion-Tr Smart automatically reduces the charging current as temperatures rise, ensuring safe and efficient operation in challenging conditions.

Automatic engine operation detection

The charger features an automatic shutdown feature when the engine is stopped, preventing unnecessary discharge of the starter battery. This is an ideal solution for power systems in vehicles and boats, where battery reliability and protection are crucial.
