I am frequently annoyed to see that my Growatt inverter is sending power to the grid when logically it would seem that it could be feeding the load or charging the battery. My installer points to the fact that these are snapshots and I am aware that there is a delay in updates, but I feel that all 4 aspects, i.e. PV Power; Consumption; Charging & Consumption, should be sampled simultaneoulsy if they are to be meaningful.

I also recognise that the Inverter capacity can limit useful storage.

I have lots of screenshots under different conditions but will just include 2 here and would appreciate comments.
