Hi all,
I have a question about calculating the PV source circuit current by using the System Advisor Model in accordance with NEC 2017 690.8(A)(1)(2).
After the highest 3-hour average irradiance is calculated for a specific PV system, can this number be multiplied by the Imp current or should it be multiplied by the Isc? Knowing that the Imp would be the actual current that is going through the conductors under normal operation conditions and not Isc.
Thank you
