Wire size
The wiring and installation methods must conform to the national and local electrical
code requirements.

PV wire size
The PV array output varies with the PV module's 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 total ISC equals any PV module's ISC.
When PV modules are connected in parallel, the total ISC equals the sum of all 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:

WARNING
The total voltage must not exceed the max PV open circuit voltage
when the PV modules are connected in series. PV open circuit
voltage 92V (MSC**10N), or 138V (MSC**15N) at 25
