I’m currently using Dynamic ESS (DESS) and noticing a gap in logic between Green Mode and Trade Mode regarding self-consumption and price optimization. Current Issues: 1. Trade Mode vs. Self-Consumption Preference I would like an option in Trade Mode where self-consumption takes priority over …

At first it seems counter intuitive, but if you can sell electricity to grid, self-consumption prioritization will decrease your earnings. If electricity is cheap currently, but will get more expensive later, batteries will end up with less charge when expensive hours come if you self-consume during…

I concur with @Slowmo that more self consumption will probably lower profit. And I don’t think Victron will revisit the long-standing issue of DESS Trade bring sell biased towards minimum SoC at the end of the known pricing window, a search on my handle will show I’ve been persistent in trying to a…

I understand why trade mode does this and I also understand why green mode doesn’t do this. But the issue is that green mode starts charging the battery in the morning while it is cheaper to charge at noon when the price is low. So an hybrid option is a smarter green mode like trade mode with prio…

Self consumption will indeed generate lower profit, but that’s the same for green mode. But like I said, green mode starts charging in the morning while it could wait for noon when the sell price is low. What I can do is use trade mode but add 10 cents to the sell price formula, this will prioritiz…

You don’t have to believe me that my method/workaround solved the actual root cause of the issue, you can test it and see for yourself. All I can say is that there are secondary effects that are apparently hard to convince people of verbally, but will become trivially obvious once you see it in acti…

So from what I understand, you use EV forecast to create some extra room for sellf consumption? Like this? [Screenshot_20260911_111019_VRM]

Preamble: by now tomorrow’s pricing is known, therefore you should set your visible time period to: ‘Next2 days’ and roll-over that EV forecast to end of day tomorrow. That said: yes and because the EV forecast gets rolled over to the next day before we arrive at the forecast time, DESS actually ne…

So for what I understand is that by planning EV charge (or any other consumption) at the end of the day ,which is removed after the planning for the next day is ready which raises the soc at the end of the day, the battery is charged a bit earlier in the morning so it has more energy to sell during …

[image] Jan: The real solution is to separate the two. Something like this should be in the works (as you both know), let’s hope it arrives soon and solves the issue. [image] [Dynamic ESS] Add SOC level, below which NOT TO SELL energy to grid, but only support AC load…

Prioritizing Self-Consumption Over Trading in Trade mode & 48h Forecasting

Q&A and troubleshooting DESS

I made something in nodered already for switching between green and trade mode depending on the consumption and solar forecast, it is related to the fact trade mode doesn’t plan for 48 hours which causes grid buy the next day when the battery starts charging to late.
