2.3 Wire size
The wiring and installation methods must conform to national and local electrical code
requirements.
PV Wire Size
The PV array output varies with the PV module size, connection method, and sunlight angle. The
PV array's short circuit current (ISC) can calculate the minimum PV wire size. Please refer to the
value of Isc in the PV module specification. When PV modules are connected in series, the Isc
equals a PV module Isc. When PV modules are connected in parallel, the Isc equals the sum of the
PV modules' Isc. The Isc of the PV array must not exceed the controller's maximum PV input current.
Please refer to the table below:
NOTE: All PV modules in a given array are assumed to be identical.
＊ Isc=short circuit current(amps) Voc=open circuit voltage.
