@Radian same here, have another 20 to 30 m of cable run to the inverter in the garage, would use ducting and a good good SWG to cut down losses

@Radian yes, I don't want them on my roof either, which is four sided, IMO it's structure is not great for bearing extra load. The decking underneath the Pergola needs shade in the summer for it to be comfortable in the sun, so I thought this would be a good idea. Will tilt the panels above 10 degrees and just overlap them on to the summer house, so that the rain from the panels flows in to the summer house gutter system. Pergola needs strengthening a bit. Might add additional panels on the summer house roof later.

Thank you @Radian...your point about max OC ratings for the module noted. In terms of what you mentioned for the min inverter start voltage, I was aware of this, but thanks for that too @SteamyTea yes of course, appreciated, I was not paying attention to what I was typing as usual, but great you pointed it out... thanks I'm going to put five of these panels on a south facing pergola Thinking of getting a hybrid inverter so I can add batteries later. thanks

Hello all, I'm planning a self build solar array, looking to use some of the new Canadian solar 655w panels in series. Looking at the max output current on these, it says 17.2A on the data sheet. Looking to run these in to a 4kwh inverter. Looking at the inverter data sheets, I figured you need to look at the max input current that it's rated at, however I notice most of these are around 12A...only the Sunny Boys seem to be around 15A. I asked a supplier what he thought and he came back and quoted me the short circuit current rating for the inverter, a Solis, which was 22A. I'm puzzled why he would use the short circuit parameter, surely you have to go by the max input current? Second point...if you connected these 655w panels in series to an inverter string whose max input was 12A, would the inverter merely clip the current input if it went above 12A? Any advice would be greatly appreciated... Thank you
