Victron Orion-Tr 12/24-15A Isolated DC-DC Converter 360W | ORI122441110

The Victron Orion-Tr 12/24-15A is a galvanically isolated DC-DC converter that steps up a 12V supply to a regulated 24V output at up to 15A, giving 360W continuous. It suits mobile, marine and off-grid installations where two battery banks need to stay electrically separate from each other.

Key features of this victron dc dc converter

• Galvanic isolation between input and output prevents ground loops and protects sensitive electronics.
• Output power 360W continuous, 12V input to a regulated 24V output at 15A.
• Wide input range copes with the voltage swings typical of real-world battery systems.
• Aluminium enclosure weighing 1.8kg, sized for tight installation spaces.
• VE.Smart networking support when paired with a compatible Bluetooth dongle for remote monitoring.
• Battery compatibility works with lead-acid and lithium chemistries on input and output.

Why isolation matters

Non-isolated converters share a common ground between input and output. In dual-battery vehicle or marine setups, that shared ground can cause charging faults, corrosion from stray currents, or damage to onboard electronics. The Orion-Tr's galvanic barrier removes that risk. At 360W it can charge a 24V service bank from a 12V starter circuit, or run a 24V load from a 12V source, and the output voltage stays regulated even when the input battery is under load from other equipment. The aluminium housing manages heat passively, with no fan needed.

Applications

• Charging a 24V service battery bank from a 12V vehicle or boat starter battery.
• Running 24V DC loads from a 12V system in campervans, motorhomes and coaches.
• Marine dual-battery installations that require isolation between banks.
• Off-grid cabins and mobile power setups with mixed-voltage DC distribution.
• Telecoms and industrial equipment needing a stable, isolated 24V supply.

Installation notes

Fit this by a qualified electrician or experienced marine or vehicle electrical engineer. Wiring on both input and output must be correctly rated for the current, with fusing on each side. Marine installs should follow NMEA and RCD Directive wiring standards. Do not exceed the specified input voltage range, and check lithium battery compatibility against the battery's BMS before connecting.
