The principles of DESS are very impressive but there are things it can do well and there are things that it will never be able to get on top of:
The magic of Dess is in extracting pricing data from a supplier and working out the best times to charge the ESS. This takes away a lot of work which would otherwise be needed in scheduling charge periods.
I am a retired person and am fortunate to travel quite often. DESS will never be able to work out a pattern of use for me. However I do have discrete usage patterns and if I were able to input my consumption profiles for say a week in advance then DESS would be fantastic.
Typically:
When home I use around 13.5 kWh per day +/- 10%.
When away I use around 6 kWh per day.
When my supplier has very low cost energy I might use 35 kWh per day.
DESS cannot know if I am going away next week so it will make a guess, but it will be wrong.
Also the Average Use profile gets skewed by the sudden swings.
So if Victron can let me have a few User configured Consumption Profiles I could tell it in advance what will be happening and DESS could then work its magic on the charge profiles making adaptations during the day as it normally does.
