DESS changes SoC overnight and will use wrong max. power settings

DESS will start using wrong numbers this midnight. As you see below, the Forecasted battery average changes from 21% at midnight (which is correct) to 55% a second later (next day). Also the DESS energy graph shows wrong numbers. Where today a maximum import and export power of 16kW is used, for some reason tomorrow it uses about 3.59kW as maximum import and export.

My settings are correct, the maximum power settings and battery settings have not changed, so what’s going on with DESS? Fwiw, DESS is set to trade mode.

Thanks.

Well, 30 minutes later it all changed for the better. Now the graphs are using correct numbers and look good again, see below.

So, my question now is, what did I just witness? Why was it using wrong variables for a short time and what changed so that it uses the correct numbers again?

Thanks.
