Victron Orion-Tr Smart 24/24-17A (400W) Isolated DC-DC Charger
Victron Orion-Tr Smart 24/24-17A (400W) Isolated DC-DC Charger
For 24V vehicles and vessels charging a 24V auxiliary battery from the alternator - common in heavier trucks, buses, and larger marine installations running a full 24V electrical system.
Galvanic isolation between circuits
As an isolated charger, the 24/24-17A keeps the starter and service battery circuits electrically separate, with no shared chassis ground - reducing corrosion risk and noise coupling between systems, particularly relevant in marine environments.
Designed for smart alternator compatibility
Built-in engine-running detection ensures the charger only draws current when the alternator is genuinely supplying power, which matters increasingly as heavy vehicle manufacturers move to variable-voltage smart alternator control for fuel efficiency.
Bluetooth setup, no dongle required
VictronConnect over built-in Bluetooth handles configuration and monitoring - select lead-acid or lithium charge profiles, check live status, and update firmware from your phone.
