Orion-Tr Smart 24/24-17A Isolated DC-DC charger

The Orion-Tr Smart 24/24-17A Isolated DC-DC Charger from Victron Energy is an advanced charger that allows you to safely charge your hotel battery directly from your vehicle's or boat's main battery. By limiting the charging current to 17A, it protects your hotel battery from overcharging, extending its lifespan and improving its reliability.

Charging optimization in dual-battery systems

The Orion-Tr Smart is designed specifically for dual-battery systems, where the starter battery charges both itself and the service battery. The three-stage charging process provides precise control over current flow, enabling efficient and stable charging, making this charger ideal for both vehicles and boats.

Remote monitoring via Bluetooth

Thanks to the built-in Bluetooth module, users can monitor and program charging parameters using the VictronConnect app. This feature allows for full control over the charger's operation without requiring direct access to the device, ensuring convenience and flexibility.

Advanced battery protection

The Orion-Tr Smart charger manages the charging current by limiting it, which protects the hotel battery from overcharging. The system automatically adjusts the current to current conditions, and in the event of elevated temperatures, the device reduces power to prevent overheating.

Automatic shutdown when engine is not running

Engine detection automatically shuts off the charger when the engine is not running, protecting the starter battery from discharging. This makes the system more reliable and ensures the batteries operate in optimal conditions.
