2.2 Wiring specifications and circuit breaker selection
Wiring and installation must comply with national and local electrical codes.
Recommended PV array wiring specifications and circuit breaker selection: Since the output current of
the PV array is affecte
d by the type, connection method and illumination angle of the PV module, the
minimum wire diameter of the PV array is calculated according to its short-circuit current; refer to the
short -circuit current value in the PV module specification (the short-circuit current is constant when
the PV modules are connected in series; the short-circuit current is the sum of the short-circuit currents
of all PV modules connected in parallel); the short-
circuit current of the PV array shall not exceed the
maximum input current.
➣ Refer to the table below for PV input wire diameter and switch:

Maximum PV
Note: The series string voltage shall not exceed the maximum PV input open circuit voltage.
