Orion-Tr Smart 12/24-15A Isolated DC-DC charger

The Orion-Tr Smart 12/24-15A Isolated DC-DC Charger from Victron Energy is a modern device that charges the hotel battery directly from the engine compartment battery. With a built-in 15A current limiter, it effectively protects the hotel battery from overload and overcharging, extending its lifespan.

Efficient charging in dual-battery systems

The Orion-Tr Smart is a three-stage DC charger, ideal for vehicles and boats equipped with dual-battery systems. It manages alternator power and transfers it to the hotel battery, allowing it to be charged safely while protecting the vehicle's main battery from excessive strain.

Bluetooth connectivity and remote management

Thanks to the built-in Bluetooth module, users can monitor and configure the charger's operation using the VictronConnect app. Remote control allows for convenient management of system parameters, significantly simplifying device operation without requiring physical access to the charger.

Advanced battery protection

Orion-Tr Smart controls and limits the charging current, effectively protecting the hotel battery from overheating and overcharging. Precise power management ensures optimal battery charging, preventing damage and extending its lifespan.

Automatic engine management

The charger is equipped with automatic engine detection, which allows the device to automatically shut off when the vehicle is stopped. This feature protects the starter battery from unnecessary discharge, which is especially useful in dual-battery systems.
