I made this a 2-star review so it might be read.

Please note that the web site photos and the web site installation specifications for wire length are not correct. In addition, the spec sheet output wire length is also not correct. However, the picture in the spec sheet clearly shows that SolarEdge has shortened the output wire lengths though it doesn't say how much. These sketches do represent the actual device. It is not long enough to string. I had to buy an extension cable for each of the optimizers we purchased to complete the installation on each job. Those of you that have installed the P-series in the past know that it was possible to wire from row to row without an extension cable.
I am writing this to make sure you are aware of this additional cost and design consideration. I am sure the equipment performs well as always but I don't know yet.
