Import only Inverter power files

[SunnyJohnny]

Hi,

Is it possible to import into PVSyst a user file with inverter instantaneous power measurements but without weather data?
My case is as follows: I have data with average inverter output power recorded every 15 minutes (from Sunnyportal). Each day is stored in a separate file having 96 records. The hour and minute is stored in the record, while the year, month and day are stored in the file name. There is no additional information (temperature, irradiance) in the files.
I would like to import this data in order to analyze the performance of the PV installation, but the "Coversion of custom measured" tool requires that the file also contain weather data. Is it possible to bypass this requirement any way?
