24V to 48V DC-DC Converters

24V to 48V Step-Up DC-DC Converters for Off-Grid Systems

Managing power in multi-voltage off-grid electrical setups requires highly reliable equipment. As modern power requirements increase, many solar installations are moving towards 48V architecture to reduce cable thickness and improve overall efficiency. When your main battery bank or alternator runs at 24V, but you need to power 48V equipment or integrate a 48V system component, a 24V to 48V DC-DC converter (often called a step-up or boost converter) is the ideal solution. Designed for demanding applications in caravans, RVs, marine vessels, tiny homes, and heavy-duty trucks, these converters provide a stable, clean direct current supply for sensitive electronics, regardless of input voltage fluctuations.

Seamless Voltage Management with Victron Energy

We stock the premium Victron Orion-Tr line of isolated 24V to 48V DC-DC converters, offering 2.5A, 6A, and 8.5A output variants. These high-quality units are engineered to maintain a steady 48V output even if the 24V input varies significantly. This continuous voltage regulation protects your downstream devices from potentially damaging voltage spikes or drops, which are common in mobile and off-grid environments where high loads can suddenly engage or disengage.

Why Choose an Isolated Step-Up Converter?

• Galvanic Isolation: Separates the input and output circuits to prevent ground loops and protect your sensitive communication and navigation equipment.
• Adjustable Output Voltage: Fine-tune the voltage parameters to match specific appliance thresholds or delicate electronic requirements.
• High Efficiency: Victron converters deliver excellent power conversion rates, minimising energy loss and heat generation in your off-grid system.
• Robust Construction: Built to withstand the vibrations, temperature variations, and tough conditions typical in Australian 4WD touring and marine environments.
• IP43 Protection: When installed with the screw terminals oriented downwards, these units achieve an IP43 rating, providing essential resistance against dripping water and dust.

Compatibility Notes

System Sizing: Ensure the continuous amperage rating of the converter meets or slightly exceeds the maximum draw of your 48V load. For reference, the 2.5A model provides roughly 120W, the 6A delivers 280W, and the 8.5A yields around 400W of continuous power.

Parallel Operation: If you need more power than a single unit can provide, up to five Victron Orion-Tr isolated converters can be wired in parallel to easily increase the total output current.

Wiring and Protection: Always pair your converter with appropriately sized DC cables to prevent voltage drop over long runs. Ensure you install suitable fuses and circuit breakers on both the 24V input and 48V output sides to safeguard the entire system from overcurrent faults.

Use as a Charger: While primarily used as a power supply, models with adjustable output voltage can sometimes be used to float-charge certain 48V deep cycle batteries, though a dedicated DC-DC charger is always recommended for complete, intelligent multi-stage battery charging.
