CAUTION

The wire size is only for reference. Suppose a long distance exists between the PV
array and the controller or between the controller and the battery. In that case,
larger wires shall be used to reduce the voltage drop and improve the system
performance.

The recommended wire for the battery is that its terminals are not connected to
any additional inverter.
