Accessories
Accessories are the parts that make the rest of the system safe and serviceable: battery cable sized to the current it carries, fuses and circuit breakers that protect that cable, and the lugs and connectors that join them. Cable is chosen by current and by the length of the run, because voltage drop grows with both, and every cable needs protection rated below the cable's own capacity. Choose accessories alongside the main components so the current ratings match the inverter, charger or battery they feed.
