Orion-Tr Smart 12/24-10A Isolated DC-DC charger

The Orion-Tr Smart 12/24-10A Isolated DC-DC Charger is an advanced DC-DC charger from Victron Energy that allows you to safely charge a hotel battery directly from the engine compartment battery while limiting the charging current to 10A. It's ideal for vehicles and boats equipped with dual-battery systems where the alternator is responsible for powering the starter and service batteries.

Efficient charging in dual-battery systems

The Orion-Tr Smart charger is designed to work with 12V/24V systems, providing stable charging for your hotel battery by limiting the charging current. This protects the service battery from overcharging, resulting in longer battery life.

Bluetooth and full remote control

The built-in Bluetooth module allows for remote monitoring and programming of the charger via the VictronConnect app. Users can remotely configure charging parameters and monitor current settings, providing complete control over the device's operation without the need for physical intervention.

Battery protection and advanced safety features

Orion-Tr Smart protects your service battery by automatically adjusting the charging current based on conditions, preventing overcharging. Additionally, built-in overheating protection reduces the charging current as temperatures rise, ensuring safe operation even in demanding conditions.

Automatic engine operation detection

The charger features automatic engine detection, which prevents unnecessary draining of the starter battery. When the engine is turned off, the charger also shuts down, protecting the vehicle or boat's energy system.
