As of late, I have come across this article and I'm not 100% sure how to apply it to the protection calculation. The following is the final part of the article listed in the title.
The calculated maximum current value shall be based on the highest 3-hour current average resulting from the simulated local irradiance on the PV array accounting for elevation and orientation. The current value used by this method shall not be less than 70 percent of the value calculated using 690.8(A)(1)(1).
My questions are, can someone provide detail as to why 70% is considered here? Also, going forward with the calculations, how would l calculate the protection, should I still do a multiplier of 125% twice for the DC, is another method considered here for protection?
