After strugling myself with DESS, I finally found (like many others) that an ESS config with minimum SOCs depending on the hour daily, is much more efficient per month that the dumb DESS (at least with a fixed-price per hour daily, with three price periods). I only hope that this post encourages VI…

21 → 22 is over and yet again DESS acted weirdly It sold from 21:00 → 21:15 with 3kw power then from 21:15 → 21:30 it covered load from grid around 600w and from 21:30 it went to self consumption Can’t understand why that sell for 15 minutes was nessesary with 3kw when it then bought next 15 minu…

@dognose can you explain DESS in this case (look my two previous posts where yesterday evening today night sales were not present) And as I thought DESS decided to sell in today morning low prices instead of yesterday evening high prices :frowning: And my battery cost is 0,03€ but it still sold wit…

And that is the reason i suggest a new parameter (do not sell less than this “price” from battery) then it is in my control. Because some of us do not want to just move energy for practically nothing. I went to sleep knowing that i have 65% of battery and wake up with only 45% of battery. And I ha…

What brothers me most is that I can’t trust DESS plan at all. Today morning I looket it and saw that selfconsumption pv to battery and evening sell from battery. But then at 12:24 I saw that DESS is buying from grid with 6kw of power. That is strange because 7 day forecast is showing more pv than …

interesting, how do you record those DESS logs?

I have custom function node in node-red that is gathering all this data from flow and when “dess_reactivestrategy” changes is writing it to text file. Then I can afterwards understand what was these values when reactivestrategy changed.

nice! would you care to share the flow?

There is so many interconnected parts in that big DESS flow of my, so copyng it all here is pointless. [image] The info if feed in to first function node from: com.victronenergy.system (0) /DynamicEss/ReactiveStrategy There is also change node that is changing topic to “Reactive” First functi…
