Efficient Charging for Service Batteries in Vehicles with Smart Alternators

The Victron 12/24V 50A Buck-Boost DC-DC Converter is designed to provide efficient charging for a 12V or 24V service battery in vehicles equipped with smart alternators, including those with Euro 5 and Euro 6 engines featuring regenerative braking. This advanced converter ensures your auxiliary battery receives a consistent charge by managing both high and low voltage scenarios, eliminating potential issues common in smart alternators.

Key Features

Versatile Compatibility

  • Supports Multiple Systems: The converter is suitable for 12V, 24V, and 12/24V systems, allowing you to charge a 12V or 24V auxiliary battery from a 12V or 24V alternator and starter battery.
  • Pre-set Charge Voltage: Ensures stable charging by regulating high voltages (e.g., Mercedes: 15.4V) and low voltages.

Intelligent Design

  • Engine Running Detection: This built-in system prevents deep discharge of the vehicle's starting battery by detecting when the engine is running. Alternatively, the converter can be activated via programmable inputs (D+, CAN bus, or (+)15 connection).
  • Fully Programmable: Easily program the converter using a simple and user-friendly PC application (USB type A male to USB type B male cable required).

Performance and Safety

  • Charge Current and Input Current Limiter: The output current is regulated by the maximum charge current setting, input current setting, and the converter's maximum operating temperature limit.
  • Status Indication LEDs: Clear visual indicators for input and output status ensure optimal operation and troubleshooting.


Ideal for various applications including:

  • Trucks, Buses, and RVs: Maintain your service batteries efficiently while traveling.
  • Marine: Reliable power management for boats with smart alternators.
  • Off-Grid and Industrial: Perfect for remote power systems and industrial equipment.

Upgrade Your Power System

Ensure your vehicle's auxiliary battery is always charged and ready with the Victron 12/24V 50A Buck-Boost DC-DC Converter. Optimize your power management and prevent battery issues with this versatile and intelligent converter.

Off-Grid and Backup

The presence of a functional electricity grid is not always as obvious as it would seem to be. An insufficient infrastructure is often the cause for an unreliable grid. Things become even more difficult when there is no grid at all. And yet you are in need of a reliable electricity supply. A local and properly functioning system is the only answer at this point. Victron Energy offers you such an answer. We are proud to offer you our modern translation for freedom and independence. Energy, Anytime, Anywhere

Energy Storage

As more solar and wind power comes on line, it becomes increasingly difficult and expensive, to ensure stability of the grid. Intermediate energy storage is therefore rapidly becoming an essential tool to keep power fluctuations on the grid within manageable limits. Moreover, as feed-in tariffs are decreasing, the business case for a home energy storage system that increases self-consumption becomes more solid every day. Intermediate energy storage increases self-consumption of harvested solar and/or wind power. The natural next step is 100% self-consumption and independence from the grid.
