I believe my DESS might be scheduling 30 minutes early. That could explain the weirdness I am seeing with tonights charging schedules. > [@A series of incorrect DESS behaviours](https://community.victronenergy.com/t/a-series-of-incorrect-dess-behaviours/29994/12): > > Tomorrow is a very interesting day price-wise. Also a few interesting DESS behaviours, as you can see. For example: Why charge today during 21-22, when there is easily enough time to charge during the night with lower tariff after 22? Why do nothing tomorrow between 16-18, when obviously that time could be spent charging and selling. If you think there is not enough round trip efficiency to make it effective, the battery cycle price is very low, so a trading opportunity exists for sure! 17:45… Another forum user had an identical looking timing issue > [@Charging battery during night time (lower price) and DESS selling with losses](https://community.victronenergy.com/t/charging-battery-during-night-time-lower-price-and-dess-selling-with-losses/46662/9): > > This evening I noticed that the DESS started to charge up the battery at 21:30 even though my prices get cheaper at 22:00. The settings for this should be correct. There’s a 30min offset in both evening and morning: @dognose , could you check this? Thank you!
