Hi, I was talking about the tool in the Ohmic Wiring Loss that allows to calculate the I^2R losses. The current considered by this tool is the Impp of the panel, but this current is (almost) irrelevant when an optimizer is installed on the panel and it's output current is different than Impp. Most of the wires in the DC side will conduct the optimizers' output current and not Impp.

When we simulate SolarEdge inverters and optimizers (and we do it a lot here in Israel), we always use the Module Layout tool. Its also written in the help section regarding SolarEdge architecture : -the electrical effect has to be evaluated using the "Module Layout" tool, which is adapted for SolarEdge optimizers. -the shadings option "according to module strings", as usually used with rectangle-strings corresponding to the modules of one optimizer input, is not really suited. It will give under-evaluated Electrical Shading loss. You can actually also use the Linear Shading option as there are practically no strings in a SolarEdge system (well actually its probably more correct to say that in SE systems we have either 1- or 2-panel string lengths). I havent seen almost no difference in energy production if use Linear Shading option or Module Layout. But I may be wrong here.

Hi, It seems that the optimization tool for wiring loss doesn't take into account power optimizers. The current considered is the Impp of the panel. Is there a workaround? Thanks
