Hello, I seem to be having a similar issue as described above using version 6.68. With no grid limitation, my project has many hours above 998KWac, as high as 1,045KWac. Setting a grid limitation at the inverter of 998KWac, instead of reaching this value the maximum hourly output at the inverter is now roughly 955KWac. Why would this be? Also, I have tried switching between applying the limitation at the inverter and at the injection point and the simulation is no different despite AC ohmic and transformer losses. This also seems strange. Thank you

I have a Format Protocol File for importing ASCII meteo data. I need to set a -30min time shift. I click open and set the shift then close the file and say yes I want to overwrite. However, when you do the conversion, no time shift has been applied. You have to do it for each file you import. And when you open the Protocol File again it says zero under time shift. But if I try to do it with a +30min time shift it works.

Hello, I'd like to echo 'solarguru'. The geographic/meteo file import can be a fairly time-consuming processing. A way to process all files in a directory and especially to do so for ASCII files. If you could pull lat/long data from files in the conversion process, create a geographic site automatically from that, and then create the meteo site using the file name that would be awesome. Thanks

I see. Thank you for the response.

Selecting the checkbox that says "Use multi-MPPT feature", and then using 90 for the "nb of inverters" instead of 30 (for an inverter with 3 MPPT).

I am running into an issue where using the MPPT feature is causing PVsyst to model significantly higher (multiple percent) Inverter Loss over nominal inv. Power. Total inverter sizing does not change and the array is being modeled as uniform. The only thing changing is going from 58 inverters to 174 MPPT inputs (for a solectria 50TL with 3 MPPT inputs). Which is a correct reflection of what actually happens? Thank you.
