I have been running my smartsolar 150/60 v3.15 for a 12v system for more than a year without issues. A few days ago i disconnected everything and changed my system to 24v. This took a few hours, then after reconnecting i initially got an overvoltage error, then switched the battery voltage to 24v and everything seemed fine at first sight. However now in the history view the days seem to start at the moment i reconnected the system, which was around 18h. So eg at 0.30 at night i already have 200wh for "today" because he shows what he received between 18h and 00.30. The internal clock seems to be correct though as the times shown in the trends view are correct (unless these times come from the smartphone and the unit just provides relative time stamps). I cannot find any setting to change the alignment and duckduckgoing for the problem did not give me useful hits.... any suggestions (except try for another disconnect around 0.00h :) ? How does he determines the start of a new day in the latest fw version?
