Weird DESS behaviour

[UpCycleElectric (Jan)]

I can’t seem to find a logical explanation.

Here the reason:

Why not charge at full speed during cheap hours/

Because DESS (Trade) will only buy what it knows it can sell profitably upto the end of the known day ahead prices schedule. And automatically attempts to reach ‘MinimumSoC’ at that same “end of schedule” moment. I have been advocating for over a year now for Victron to acknowledge that this is a design/architectural flaw that creates a direct downward SoC bias that, unfortunately I would almost say, often but not always gets masked by any counter upward SoC bias, notably solar installations ‘…

In your case, what you notice is that DESS refuses to start charging, until the new pricing forecast for tomorrow rolls in.
