1000W/m2.)
2.3 Wire size
The wiring and installation methods must conform to the national and local electrical code requirements.
PV wire size
The PV array's output current varies with size, connection method, and sunlight angle. Its ISC (short
circuit current) can calculate the minimum wire size. Please refer to the ISC value in the PV module's
specifications. When the PV modules are connected in series, the total ISC equals any PV module's ISC.
When the PV modules are connected in parallel, the total ISC equals the sum of all the PV module's ISC.
The PV array's ISC must not exceed the controller's maximum PV input current. For max. PV input
current and max. PV wire size, please refer to the table below:

The total voltage must not exceed the max when the PV modules are connected in
series. PV open circuit voltage (Tracer**10AN)/138V
