A 360W isolated DC-DC charger that takes 24V input from a truck, bus or marine alternator and charges a 12V auxiliary battery at up to 30A. Galvanic isolation separates the input and output chassis grounds so the 12V service circuit sits on its own ground rail. Fits heavy-vehicle service builds, bus conversions, marine house banks and 24V agricultural rigs feeding a 12V accessory system.
Housed in a 130 × 186 × 80mm aluminium chassis with screw terminals for in-line wiring and a fanless passive cooling design. Weighs 1.9 kg. Charges via an adaptive 3-stage algorithm (bulk, absorption, float) with 8 preprogrammed battery presets covering AGM, gel, lead-acid and LiFePO4. Built-in Bluetooth pairs with the VictronConnect app for monitoring, configuration and firmware updates.
Not protected against reverse polarity. Reversing the input will damage the unit permanently, so fuse both input and output circuits at the source and use at least 6mm² wiring. The charger is 24V input only; do not install on a 12V alternator or a 48V system.
What sets it apart
24V to 12V step-down — purpose-built for 24V vehicle systems feeding a 12V house circuit.
Galvanic isolation — separate input and output ground rails for safe mixed-ground installs.
Bluetooth built in — monitor state and tweak settings from the VictronConnect app.
8 battery presets — one-tap profiles for AGM, gel, lead-acid and LiFePO4.
Adaptive 3-stage charging — bulk, absorption and float match the battery's actual state.
Engine-shutdown detection — stops the converter when the vehicle stops to protect the starter.
Parallel-capable — stack multiple units for higher combined current.
Fanless passive cooling — no moving parts, no fan noise, no maintenance.
