Useful voltage drop calculator with a given wire gauge and current. This, in combination with a current carrying chart is essential for low voltage i.e. 12 volt builds which usually have very high currents. Choosing wire size based only on current carrying limits will often result in large voltage drops before reaching your inverter and losses of 5% or more or your stored Kwh.
