My DESS has strange behaviour and I think this is due to consumption and solar prediction that are way off. This morning my batteries were charged from the grid at SoC 70% and in daytime at noon my batteries were full. Predicted consumption is very high, more as double as it should be. 
Maybe this was because of me playing around when I first installed the system. Now I would love to make a fresh start and delete the history that is used to make the predictions. Can someone tell me how to do that?
My goal for now is to maximize my own solar usage. With expected shortage of (stored) solar energy, i want to charge during off-peak or consume during off-peak hours on low tarif. I think DESS green mode is exactly what I need.
This graph is for tomorrow. What I see is a constant SoC during the night and a dropping SoC during solar period. My consumption is about 1000Watt all through day and night.
