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.
