said allaw Posted February 12 Share Posted February 12 why when ever we change the power factor the active power maintain a constant and the reactive and apparent power changes even though from what i know the apparent power is the constant as i have certain number of the inverters kindly illustrate this matter Link to comment Share on other sites More sharing options...
Lazare Fesnien Posted February 13 Share Posted February 13 Dear Said Allaw, PVsyst treats the Reactive power (or energy) linked to the PV production. This is done by a constant factor (Cos(Phi)) specified/required by the Grid manager. This reactive power is proportional to the produced energy. See the help " Project design > Grid-connected system definition > Power Factor". A reactive power may be created or absorbed, depending on your definition (Leading or Lagging power factor) Link to comment Share on other sites More sharing options...
