So at this time. This detail is technically irrelevant.
And in many cases to reduce complications its best to stay out of beta if you need the system to function right and also bug report. With all the dess related things i am seeing posted by yourself,it may be the best course of action.
Could it be that your batteries are forecasted to be at 100% when those more expensive hours come? In that case self-consumption could be more profitable because you would not be able to sell that energy anyway as batteries would reach 100% SOC from solar anyway
Now it’s the other way around, dess charges battery instead of selling to grid while charging battery later would be more profitable. The system is in Trade mode.
To me, it looks like all of the cheap hours are already reserved for charging, and at around 12:00 there is barely any solar to cover the consumption. So it charges now for the battery to be full in the evening, where there is a substantial price increase.
Yes, but you also have forecasted consumption in those quarters which would then have to be taken from the grid. But I have also noticed that if there is way more solar than expected, DESS might make strange decisions.
