High Efficiency, silent DC-DC converters to switch between 12, 24, and 48 volt systems. All units can be used in parallel to increase the required amp demand.

Choose the voltage, then choose your model based on size (specified by maximum output amps).

Each converter is limited by the maximum power it will provide & it is best to keep constant loads at under 50% of its rated power to reduce heat and maximize equipment life. Your DC equipment's watts divided by the voltage will give you the Output Amps you need.

Isolated vs. Non-Isolated converters: For most uses, you are perfectly fine & get best efficiency with non-isolated converters. They share a common negative. They may have 4 or 3 connectors on the casing. For models with three binding posts, such as the Victron Orion-TR series, you connect the negative of both your 24V and 48V systems to the same post.

In comparison, an isolated converter creates a new circuit. Its output positive and output negative are not a part of the same circuit as the input. It is better suited for powering sensitive electronics.

You can always use an isolated transformer instead of a non-isolated one, they just tend to be more expensive and ironically slightly less efficient. Victron isolated converters are for that reason a staple in telecommunications rooms for powering DC equipment. If you're running motors, batteries, or the like, non-isolated converters will be your standard choice.

What about 12 vs 13.8 Volts - 24 vs 27.1 Volts - 48 vs 54.4 Volts - What is the difference?

If you are powering motors, dc refrigeration, or wish to keep other battery banks in sync other battery banks in sync, the 13.8 - 27.1 - 54.4 voltages provide a boost in voltage to support full power equipment operation, longer wire runs, or the ability to keep LFP batteries topped off without risk of overcharge.

It is important to note that the transformers do not have any charging algorithms and instead output a steady voltage up to the transformer's rated current output (amps). 4S, 8S, or 16S LFP banks can be relatively safely floated at these voltages which corresponds to 100% SOC. An example use scenario may be using a 48V ➔ 24V converter to maintain an auxiliary 24 volt battery and devices from your larger 48V solar system. Another example may be using a 12V ➔ 24V converter to charge an on-vehicle 24 volt battery from the engine's 12 volt alternator.

In all cases we have the best solutions to help your conversion needs.
