12V · Victron + Fogstar · Prototype
Drag Victron parts onto the canvas and it wires them up, sizes every cable and fuse, and checks the system as you go. Or answer a few questions and it builds the layout for you.
Tap a part to add it, then drag it into place. Cable lengths follow your layout (one grid square is 10cm), so moving a part re-sizes its cable and fuse. Tap a part to edit or buy it.
Sized for under 3% voltage drop, with every cable able to carry its full fuse rating.
