A 24V-to-24V isolated DC-DC charger for builds where the starter system and the house system need to stay electrically separate. Galvanic isolation means there is no shared ground path between input and output, which eliminates a whole category of problems: ground loops, stray current corrosion, and noise crossing from the vehicle side into sensitive equipment.

When isolation matters

On a simple truck build you can usually get away without it. It starts to matter when you have a chassis with questionable grounding, when you are mixing systems from different manufacturers, or when you are running audio, comms or instrumentation that picks up electrical noise. It is also standard practice on anything that spends time near water.

Smart, not just a block

Bluetooth built in. Set the battery chemistry and charge profile in VictronConnect, then monitor it live. Adaptive multi-stage charging rather than a fixed output voltage, so the house bank actually fills correctly.

Check the voltages

This is 24V in, 24V out. Most overland builds are 12V and want a 12/12 unit. Tell us your system voltage and we will confirm the right model before you order.
