Hi @Victon,
at my instalation DESS forecast is over system physical possibilites. I have just one MPPT-RS 450/200 which is cappable to deliver max ~11kW of PV at my voltage level.
So why DESS forecast almost every day is going over 15kW? System limitation is not considered? Can I somehow influence PVmax forecast?

Have a good day
How many days worth of data do you have? I think it takes about a month to get an accurate forecast.
1 year+ at least. That is not the cause.
Hmm, you shouldn’t need to tell the system anything about your solar installation. It should learn from the historical data. Do you have your location set correctly in VRM?
One thing you could try to change your location away from what it is currently set to, and then change it back right after (I’ve seen some weird behavior solved by this before, such as time zone bugs). I say this because the forecast uses your location setting.
You can then try to reset your solar forecast under Settings > General.
I don’t think the solar forecast takes anything else into account, but it’s possible there is some issue with your historical data which resetting may resolve…
