API field
IV shading current scale (override)
Shading current scale for an inverter given by library id
What it is
The shading current scale of an inverter chosen by its library or OND file id; it replaces the choice stored with the inverter.
Typical values and how to get it
Chosen on the Model tab.
Values
Scale the curve by the electrical shading = electrical_fraction (default): the array curve's current is multiplied by the share of power the electrical shading leaves · Leave the curve unscaled = off: the electrical shading loss is taken as power only, and the curve keeps the current of the unshaded array
