Adaptive 3-stage charge algorithm: Fully automated Bulk, Absorption, and Float phases perfectly maintain your auxiliary battery.
Bluetooth Smart Built-in: Wireless monitoring, status checking, and custom configuration profiles via the VictronConnect App.
Smart Alternator & Engine Running Detection: Prevents auxiliary loads from draining the starter battery by only drawing power when the alternator is generating current.
Galvanic Isolation: Offers full 200V DC isolation between the input, output, and chassis ground to safeguard sensitive electronic systems from ground loop noise.
Parallel Capability: An unlimited number of units can be combined in parallel to match high power output scaling requirements.
Where to use it
The Orion-Tr Smart DC-DC charger is an adaptive 3-stage charger (bulk – absorption – float) designed for dual battery systems, such as in vehicles or on boats where the starter battery (hence the alternator) is used to charge the service battery. The name "Smart" comes from its built-in Bluetooth connection, where the charger can be monitored and configured via Bluetooth and can be remotely controlled via a remote on/off switch and has an engine-running detection mechanism. This isolated model allows the input and output to have separate chassis grounds.
The Victron Orion-Tr Smart 48/12-20A charger is an exceptional choice for modern dual-battery arrangements across vehicles, 48V battery carts, trucks, or maritime craft where a 48V primary battery bank or alternator setup needs to supply steady, highly controlled 12V output to a dedicated house battery or critical localized DC equipment loops.
