Description
xVictron Energy 50A Buck-Boost DC/DC Converter
The Victron Energy 50A Buck-Boost DC/DC Converter is a non-isolated DC-to-DC converter designed for mobile, off-grid and vehicle-based electrical systems where the input and output voltages differ or fluctuate. It is suited to professional installers working on campervans, boats, trucks and off-grid installations that require stable, regulated DC power from a variable source.
Key Features
- 50A continuous output current for high-demand DC loads and battery charging applications.
- Buck-boost topology allows the converter to step voltage up or down, maintaining a stable output regardless of whether the input is higher or lower than the target output.
- Non-isolated design provides efficient power conversion with lower heat generation compared to transformer-based isolated converters.
- Compact and lightweight at 1.39 kg, suitable for installation in space-constrained environments such as vehicle cabinets and marine enclosures.
- Part of the Victron Energy DC/DC converter range, compatible with Victron system monitoring and integration where supported.
- SKU ORI303050000, GTIN 8719076023128, supplied by Voltacon Solar.
Product Overview
A buck-boost converter differs from a simple buck (step-down) or boost (step-up) converter in that it can handle input voltages both above and below the desired output voltage. This matters in real-world vehicle and off-grid systems where battery voltage sags under load, alternator output varies with engine speed, or two battery banks of different nominal voltages need to be connected. A fixed-topology converter would either fail to regulate or shut down under these conditions; a buck-boost handles them without interruption.
The non-isolated architecture means the input and output share a common ground reference. This is standard practice in most 12V and 24V vehicle and marine systems and results in a more efficient conversion path. Installers should confirm that a shared ground is appropriate for the specific system before specifying this converter over an isolated alternative.
At 50A output, this converter is capable of charging a secondary battery bank at a meaningful rate or supplying substantial DC loads. It is well suited to split-charge systems, DC-coupled solar storage topologies, and any application where a regulated DC rail must be derived from an unregulated or variable source.

Installation Notes
This converter should be installed by a qualified electrician or experienced system integrator familiar with DC power systems. As a non-isolated converter, the input and output share a common ground; verify this is compatible with your system topology before installation, particularly in marine environments where ground loops can cause corrosion or interference. Ensure all cabling is correctly rated for 50A continuous current and that appropriate fusing is fitted on both the input and output sides in accordance with wiring regulations. For vehicle installations, follow the relevant automotive or marine wiring standards applicable to your application.
