The Victron Orion-Tr 24/48-8.5A is an isolated DC-DC converter that steps a 24 V supply up to 48 V. It accepts 16 to 35 V in and is rated for 8.5 A continuous output, or 400 W at 25°C. The output voltage range is 40 to 60 V, and the output is galvanically isolated, rated 200 VDC. Its operating temperature range is -20 to 50 °C.

Our take

This one raises a 24 V supply to 48 V, with the 200 VDC isolation keeping the two sides electrically separate. At 8.5 A continuous it carries 400 W at 25°C, so the 48 V load needs to be sized against that figure.

From our buying guide

Each maker sets its own alternator rules. Battle Born calls a DC-to-DC charger a simple and safe way to use alternator charging.

Check before you buy:

  • It can follow your battery's profile, since not every charger can follow a lithium maker's.
  • Battle Born warns that a BMS shutdown leaves the vessel without power, and that one during alternator charging can severely damage the alternator.
