during peak pricing, when batteries are close to full, why does DESS take from the grid? Even a simple ESS knows to take from the batteries during the day but DESS uses the grid instead of inverting? it makes no sense

why does DESS take from the grid when my batteries are full
Yeah I turned DESS off this evening for this exact reason. My batteries basically sat at 100% all day and that was with minimal solar energy available. Meanwhile the grid is being used for all loads even though it's peak rate.
There are times that DESS seems to work really well but I tend to lose confidence in it at times like this. I think I'm just going to build my own custom Node RED flow to do exactly what I want.
Great to know someone else finds it unusable. I tried to get my head around node red but couldn’t manage. If theres any way to share your node red set up file i would be very grateful
I'll have to write it first! :)
I have good days and bad days with DESS and a lot of the time it seems to work quite well. Maybe I'll try to understand what's going wrong before abandoning it.
I have exactly the same issue of buying from the grid with 100% full battery's. I have 62KwH battery so enough capacity during the evening and night. Also in the morning time DESS will sell all the power before the sun/PV produce enough power. I have to turn DESS ON and OFF depending of the consumption.
