I have a Dye 5kW inverter and it also draws power from the grid. I my case +-350W. This while the sun is shining and it is charging the battery at 1.5 kW. Its own CT measurement shows 0 most of the time. My inverter is set to "load first". No charging from the grid is done or set up. If I would now switch on the stove (non essential load) that uses about 1.2 kW the power drawn from the grid can go op to 700W. The total inverter load at this point is well below 5kW so it is not a case of running out of capacity. I have a electronic municipality meter and it shows a error when pushing power back. In this case there is no error shown. I measure the inbound thick red wire with an Owl Electricity meter. I also verified, with great effort, that the municipality meter increases accordingly - there is a bit of a discrepancy with the Owl but not significant. After playing with settings for days on end and after I contacted the service centre, I just gave up. Bought another Lithium battery and disconnected it from the grid.
