CAUTION: The wire size is only for reference. If there is a long
distance between the PV array and the controller or between
the controller and the battery, larger wires can be used to reduce the
voltage drop and improve performance.
CAUTION: For the battery, the recommended wire will be
selected according to the conditions that its terminals are not
connected to any additional inverter.
