All-in-one solar charge inverter 8
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 affected 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:
