F Fuse/Circuit breaker The tracking system should be
equipped with an overcurrent
protection device or component. The
power cable between the device or
component and the wiring terminal
should be no longer than 2.5 m.
Therefore, a fuse or a circuit breaker is
recommended.

The solar inverter has an RCMU inside. Its external AC switch should be a three-
phase circuit breaker or other AC load circuit breakers to safely disconnect the
solar inverter from the power grid.
● The cable diameter must comply with local cable standards.
● The factors that aect cable selection include the rated current, cable type, routing
mode, ambient temperature, and maximum expected line loss.
