48V to 24V DC-DC Chargers

Victron 48V to 24V Isolated DC-DC Charging

When a 48V battery bank is the heart of your system but some equipment or a secondary battery still runs at 24V, a dedicated 48V to 24V DC-DC charger bridges the two voltages. This collection features the Victron Orion-Tr 48/24-16A Isolated DC-DC Charger. It is built to deliver a regulated 24V output from a 48V source in marine, off-grid, commercial and industrial installations.

The Orion-Tr range is part of Victron's wider 24V DC-DC chargers line-up. The 48/24 model is the choice where the source is a 48V house bank rather than a 12V or 24V alternator circuit.

Why Choose an Isolated Orion-Tr 48/24-16A

An isolated converter galvanically separates the input and output circuits, so the 48V and 24V sides do not share a common negative. This matters on boats, in mixed-voltage vehicles and in commercial systems where isolation helps manage ground loops, electrolysis risk and electrical noise between circuits. If you are unsure which design suits your build, our guide to isolated vs non-isolated converters and DC-DC chargers explains the differences in detail.

• 48V input, 24V output: steps a 48V bank down to supply 24V batteries or loads
• 16A rated output: suited to 24V electronics, pumps, lighting and auxiliary battery charging
• Isolated topology: separates input and output circuits for cleaner, safer mixed-voltage systems
• Victron Orion-Tr build quality: designed for demanding mobile and stationary installations

Typical Applications

A 48V to 24V charger is commonly used where a 48V lithium bank powers an inverter or propulsion system and legacy 24V equipment still needs a reliable supply. Common examples include:

Marine vessels running 24V navigation, bilge or engine room electronics from a 48V house bank. Off-grid homes and tiny homes with 24V pumps or control gear. Trucks and commercial or industrial vehicles that combine 48V systems with existing 24V accessories.

Compatibility Notes

Before ordering, confirm that your source is a nominal 48V system and that the combined draw of your 24V loads, or the charge current required by your 24V battery, sits within the 16A output rating. Where the load or charge demand is higher, consider sharing it across appropriately sized units or reviewing the overall system design. If your source voltage is 24V rather than 48V, the 24V to 24V DC-DC chargers are the better match. Correct cable sizing and fusing on both the input and output sides are essential for safe, efficient operation.
