Yes I think you have seen similar issues, when the estimates of consumption or solar are off it can cause grid usage. My system has just started pulling from Grid as the clouds have come over and where it forcasted solar there is now none… even though the battery has plenty at 53% I think the EV and heat pump loads are throwing it off somewhat.

I’m not on beta, so this for now is not working for me.

However everytime I try it it consumes grid power to cover house loads during peak energy costing. I am on Octopus Intelligent Go in the UK so 25p peak and 7p off peak (day and night). Outgoing export at 15p. DESS seems to do a good job at dumping the battery and planning ahead. However if I boil the kettle for a cuppa or put the oven on during the day DESS takes that energy from the grid and not the h… Cheers for the pointers, at least I know its working as well as can be expected for the time being. --- _[View the full topic](https://community.victronenergy.com/t/dess-importing-from-grid-when-battery-has-capacity-but-is-idle/8423)._
