The Victron Energy Orion-Tr Smart Isolated Chargers are 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. Suitable for high temperatures up to 55C with a full rated output up to 40C.


Bluetooth Smart-Enabled:

  • Any Bluetooth enabled smart phone, tablet or other device can be used to monitor, to change settings and to update the charger when new software features become available
  • Instant Readout: The VictronConnect App can display key data, including warnings and alarms, on the Device list page without the need to connect to the product

Fully Programmable:

  • Battery charge algorithm (configurable) or fixed output
  • Smart alternator compatibility: engine running detection mechanism

Adaptive 3-Stage Charge Algorithm: Bulk – Absorption – Float

  • For lead acid batteries it is important that during shallow discharges the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged
  • For lithium batteries absorption time is fixed, default 2 hours
  • Alternatively, a fixed output voltage can be chosen

Suitable for Use in Vehicles with a Smart Alternator: The built-in engine shutdown detection will stop the converter when the engine is not running. This prevents unwanted discharge of the starter battery (see manual for details).

Remote On/Off: A remote on/off switch or relay contact can be connected to a two-pole connector. Alternatively, the H terminal (right) of the two-pole connector can be switched to battery plus, or the L terminal (left) of the two pole connector can be switched to battery minus (or the chassis of a vehicle, for example).

All Models Are Short Circuit-Proof & Can Be Paralleled to Increase Output Current: An unlimited number of units can be connected in parallel

High Temperature Protected: The output current will reduce at high ambient temperature

IP43 Protection: When installed with the screw terminals oriented downwards

Screw Terminals: No special tools needed for installation

Input Fuse: Not replaceable
