For use in dual battery systems in vehicles or on boats where the (smart) alternator and the start battery are used to charge the service battery. The unit can be monitored and programmed via Bluetooth and can be remotely controlled via a remote on/off switch and has an engine running detection mechanism.

The Orion Tr-Smart charger can be used in 12V or 24V systems and is suitable for both lead acid and lithium batteries. Models are available up to 400W and unlimited multiple units can be connected in parallel to increase output power.

Suitable for high temperatures up to 55°C with a full rated output up to 40°C.

The engine on detection mechanism simplifies your Orion-Tr Smart DC-DC Charger system by detecting if the engine is running without wiring additional switches or sensors. The factory default setting of the engine on detection is based on a generic smart alternator system which can be re-configured with the VictronConnect app. The VictronConnect app can be downloaded from: http://www.victronenergy.nl/support-and-downloads/software/

Configuring the engine on detection depends on the voltage generated by the alternator when the engine is running. Regular alternators will generate a fixed voltage (e.g. 14V) whereas smart alternators generate a variable output voltage which can range from 12.5V to 15V. Especially smart alternators in a regenerative braking system show large alternator voltage variations. The next sections explain the engine on detection sequence and the engine detection setup with VictronConnect.
