This is not a solution this a work around. This issue is mentioned several times on this forum. For example here. > [@DESS: strange behavior 10 minutes before the hour](https://community.victronenergy.com/t/dess-strange-behavior-10-minutes-before-the-hour/18709): > > Hello all, While monitoring my DESS setup (latest Cerbo release) I notice the system is behaving unexpected and strange just before the hour (10 min aprox.). The normal expected schedule seems to get overruled and the opposite is happening. In the graphs below an example of this, where it starts charging from grid at high price. Dumping back during the night while prices are low also feels funny. Can someone explain what is happening here? I played around with several parameters but no luck… It seems there is a fix in the latest beta but I wasn’t able to test this since other issues in this beta release. But you could try the latest beta (3.60~60) and see if it’s better ![image](https://europe1.discourse-cdn.com/victron/original/3X/b/e/be1eb141bfa152221ca279f39f21cb6b7e2d73c2.png) --- _[View the full topic](https://community.victronenergy.com/t/bug-multiplus-2-dess-charging-during-high-tariff-costing-money/25422)._
