Let''s say you have a 12-volt battery bank, so how do we know the current that is fed to the batteries? Easily using the same relation: Current (I) = Power (P) / Voltage (V) I = 200w / 12vI = 16.67 A This means that the current that is flowing from the solar controller through wires to the batteries is approximately doubled, from 8.85 to 16.67 amps.
