Hello,

The Pnom ratio, also known as the DC-AC ratio, refers to the ratio of the nominal DC power output of a solar panel array to the nominal AC power capacity of the inverter, indicating how much DC capacity is installed relative to the inverter's AC capacity. Thus, the Pnom ratio changes if you adjust the number of panels installed or the capacity of the inverter.

Kind regards
