Victron Energy ORI303100000 100A Buck-Boost DC/DC Converter

Victron Energy 100A Buck-Boost DC-DC Converter

The Victron Energy ORI303100000 is a fully programmable 100 A non-isolated DC-DC buck-boost converter engineered for charging 12 V or 24 V auxiliary service batteries in vehicles equipped with Euro 5 and Euro 6 smart alternators. Because smart alternators continually vary output voltage based on operational parameters and regenerative braking, this converter steps voltage up or down to ensure a stable, regulated charging profile that protects both alternator coils and starter batteries.

Designed for marine, overland, and commercial fleet applications, the unit provides bidirectional conversion between 12 V and 24 V systems (12/12V, 24/24V, 12/24V, and 24/12V). Built-in programmable engine-running detection activates charging automatically when the vehicle is running without requiring a separate D+ ignition wire, while independent input and output current limiters protect AGM, GEL, and lithium batteries from overload.
