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 I
SC
of PV array.
Please refer to the value of I
SC
in PV module specification. When the PV modules
connect in series, the I
SC
is equal to the PV module‘s I
SC
. When the PV modules
connect in parallel, the I
SC
is equal to the sum of PV module‘s I
SC
. The I
SC
of PV
array must not exceed the maximum PV input current, please refer to the table as
below:

NOTE: When the PV modules connect in series, the open circuit voltage of the
PV array must not exceed 138V (25℃).
