Field notes
The workflow can start with a device list—examples include a fridge, fan, Starlink, microwave, and coffee maker—or with a manually assembled diagram. The page says users can change system voltage and compare how that affects current and cable size. Its sample bill of materials breaks out quantities and lengths for items such as cable and ring lugs, with store links and displayed prices.
