Victron Energy Orion-TR Smart DC-DC Battery Charger Isolated, 12V, 24V, and 48V Options for DC-DC Charging with Dual Battery Systems

The Victron Orion-Tr Smart Charger takes in power from alternators or batteries to charge a separate battery bank for use in energy storage systems. The built in alternator detection feature is ideal for charging secondary batteries from an alternator and starting battery in vehicles, boats and RVs.

Adding an Orion-TR to an installation with multiple different voltages bridges the operational gap by converting one DC voltage to another. For example, the 24V/12V model will charge a 12V service battery from a 24V starter battery. Be sure to select the appropriate charger for the intended source and destination system voltage.

Unlike a voltage regulator, the DC-DC converter can continue to operate if the input voltage is lower than the output voltage.  It will boost the voltage to appropriate levels for proper battery charging.

These units have IP43 rating, making it suitable for both mobile, marine and residential systems. For applications requiring more current, multiple Orion-Tr Smart Chargers can be connected in parallel for increased capacity.

VictronConnect is an app that enables mobile configuration and connects via Bluetooth. Adjust charge settings for use with lithium batteries or lead-acid batteries, or use it as a power supply with a fixed output. VictronConnect will show the current input/output voltages, and the Orion-Tr’s charge stage.

These chargers have galvanic isolation between the input and the output. Galvanic isolation eliminates the chances of forming ground loops, faults from differences in ground potential, and galvanic corrosion in marine applications.
