Hello, I have been encountering more and more equipment that isn't yet on PVsyst but am under the impression that PVsyst has given some parties access to more files. Is there any way to get access to a larger database of module and inverter files or is the only way to go through the manufacturer. I would input the information myself, but am not confident in the specifications that don't come in the spec sheet and PVsysts default values of them (rshunt etc...) Thank you!

Hello, It seems that with each new version of PVsyst there are significantly more stringing limitations that seem either buggy or unnecessarily restricting, specifically with the SolarEdge optimizer strings. Maybe there is something I'm missing, but layouts that I could easily accomplish earlier this year are now impossible to recreate and the only option I see is to revert back to older versions. Any help is much appreciated! The main issue has been small windows of allowed string sizes for optimizers, preventing me from creating systems which are clearly possible when looking directly at the specs of the equipment. While I can see that disallowing certain string sizes could help avoid errors in general, it also provides significantly less flexibility, particularly when designing multi-orientation rooftop designs. A suggestion to the software would be to allow more detailed mixed orientation inputs to account for the decreased flexibility in string sizing. This is one of the main benefits of using the optimizers and it seems like the importance of this function has been made impossible to model using PVsyst. I have also noticed that for certain system designs, PVsyst will not allow me to input an even number of optimizers. I.e. when I select to have 12 in series it will say the range is 8-11, but when I increase to 13 optimizers in series, it says that the range is 8-13 and allows it; and so on for 14, 15 etc... I have included snapshots below: Does anyone know why this happens? Any suggestions for work arounds would be awesome!

Hello, I'm wondering how to best choose the weather station that will be most accurate for running a generation report. It is my understanding that the weather patterns at different weather stations can vary greatly based on the microclimate. However, I have also noticed that class 1 weather stations systematically provide significantly higher production results. Do you know why this is, and whether there is an industry standard for choosing weather files? Thank you,
