Component library

The catalog, with its wiring attached.

232 real parts — batteries, chargers, panels, fuse blocks, the gear you plug in. Each page shows where the positive and negative land, what the terminals are rated for, and the cable and fuse we would pick for a reference run, so you can see the wiring before you draw it.

How the numbers are made

Your own parts

Draw it with the parts you actually own.

Nothing to install and nothing to sign up for. Drag in a battery and one light, and the wire and fuse for that run appear on the drawing.
