Component library

The catalog, with its wiring attached.

229 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.

BatteriesHouse, starter, AGM and lithium batteries with terminal data and reference conductor sizing. 26 parts ChargersDC-DC, shore and solar chargers compared by voltage, output, terminals and installation impact. 83 parts Solar panelsRigid and flexible solar panels with electrical limits, terminal maps and system-fit references. 18 parts Power sourcesAlternators, generators and shore sources with ratings and practical connection references. 9 parts EnginesMarine engines and starting-system references for planning complete DC electrical systems. 14 parts DistributionBusbars, fuse blocks, switches and distribution hardware with complete terminal topology. 31 parts LoadsInverters, pumps, lighting and onboard loads with draw, surge and reference protection data. 30 parts MonitoringBattery monitors, shunts and sensors with their terminal roles and system placement made explicit. 18 parts

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.
