Hi Johan,
SAM assumes that January 1 is a Monday, and that weekends are Saturday and Sunday. It is not possible for Saturday and Sunday to have different TOU periods.
You can specify up to 36 TOU periods. Use the letters "a" through "z" in the Weekday and Weekend schedule matrices for Periods 10 through 36.
It is not possible to change the currency symbol in SAM.
Best regards,
Paul.
