Is the Dynamic ESS solar forecast going crazy?

My DESS is set to trade mode, works very good. Until yesterday evening that is. All of a sudden it uses wrong solar numbers. Way too high numbers and that effects the forecast and thus planning of the trade mode. See the sequence of events below. It goes from an absurd forecast at 00:00 to a normal forecast at 10:00 to again crazy solar numbers at 17:00, for today but also tomorrow.

I certainly have not changed any settings/numbers and they are all set as they should.
There must be something going on with the remote Victron software? Is anyone else experiencing this?

Thanks

Looks like a deja-vu of DESS how is solar forecast working?

So at least you are not alone…

The solar prediction has been stable for the last few days, very happy about that. It’s pretty close to what is was a week ago.

Assuming that you guys intervened and as I am a programmer myself, I’m very curious what the issue was. Would you be able to share that?

Thanks
