Hi Frederik,
The older version -- PVSol 2019 (R14) supports the .slg file for the consumption profile. Kindly see attachment and below screenshot for your perusal.
My issue on the new version PVSol 2020 (R2) is that my load profile database are all in .slg file and I can't import it since it doesn't support the file.
Maybe you could provide any workaround on this?
Appreciate the respond! Thank you!
