Sol-Ark TOU Off days?

If I setup my TOU settings for M-F and leave Sat/Sun unselected, what will the behavior be on those days? Does it just completely ignore TOU and not use any battery power, and just keep the batteries at 100%? Does anyone who has M-F TOU leave sat/sun unselected, or to you just leave it on all 7 days anyway?

If you leave Sat/Sun unselected, then it will use all the other settings to figure out what to do. It will use the Batt Setup/Charge settings to figure out when to start charging from the Grid. It will switch to Battery when grid is down, or Grid peak-shaving (Basic Setup / Advanced).
