12V to 24V DC-DC Converters

High-Performance 12V to 24V Step Up DC-DC Converters

Powering 24V appliances from a standard 12V battery bank is a common challenge for off-grid touring and mobile setups. Our premium selection of 12V to 24V step up DC-DC converters (also referred to as voltage boosters or 12 to 24 volt step up converters) bridges this gap effortlessly. By stepping up the input voltage, these smart devices allow you to run specialised 24V equipment directly from your existing 12V system.

Whether you are upgrading a caravan, 4WD, marine vessel, or off-grid tiny home, installing a reliable 12V to 24V converter ensures that your sensitive electronics receive a clean, stable power supply. This is particularly important for 24V diesel heaters, refrigeration units, communication equipment, and specific lighting arrays that will not operate efficiently on standard 12V power.

Industry-Leading Victron Energy Solutions

We stock an extensive range of high-quality Victron Energy converters, engineered for demanding Australian environments. The Victron lineup covers everything from compact 5A units for small electronics to heavy-duty 100A Buck-Boost converters designed for serious power demands. Designed with robust internal components, these units prevent voltage drops and protect your valuable appliances from power fluctuations.

How to Choose the Right 12V to 24V Converter

Selecting the correct 12V to 24V DC converter depends on your specific appliances and electrical architecture. Keep these critical purchase criteria in mind when matching a converter to your setup:

• Isolated vs. Non-Isolated: Isolated DC-DC converters feature separate input and output circuits, which breaks ground loops. This is vital for marine applications to prevent galvanic corrosion and for sensitive audio/visual equipment. Non-isolated converters share a common negative and are typically more compact, making them ideal for standard resistive loads.
• Environmental Protection: If you are installing the converter in an engine bay, a damp boat hull, or an exposed 4WD canopy, opt for a waterproof DC-DC converter like the Victron Orion IP67 series, which is fully encapsulated to resist water, dust, and vibrations.
• Current and Wattage Requirements: Check the continuous and peak current draw of your 24V appliance. We offer converters ranging from 5A (120W) up to 100A (2400W). Always size your converter with a 15 to 20 percent safety margin above your maximum expected load to ensure ultra durable performance without overheating.
• Buck-Boost Technology: For smart alternator compatibility and complex charging or power delivery scenarios, the Victron Buck-Boost range can regulate both under-voltage and over-voltage inputs to provide a flawless 24V output.
