2.3 WIRE SIZE
The wiring and installation methods must conform to all
national and local electrical code requirements.
PV Wire Size:
Since PV array output can vary due to the PV module size,
connection method or sunlight angle, the minimum wire
size can be calculated by the Isc
＊
of PV array. Please refer
to the value of Isc in the PV module specification. When PV
modules connect in series, the Isc is equal to a PV modules
Isc. When PV modules connect in parallel, the Isc is equal
to 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 as below:
NOTE: All PV modules in a given array are assumed to be
identical.
＊Isc=short circuit current(amps) Voc=open circuit
voltage.
