Statman,
I seem to be fresh out of ideas. This is what I am seeing this morning:
I can associate events in the house with this graph: aircon in bedroom switched off, espresso machine heated up, pool pump started, sprinklers and deep well pump coming on and turning off..... Consumption from PV is reduced when consumers go off. All as it should be. I have turned feed to the grid off for the time being.
So I could not imagine what could be wrong in your system.
One thing might be worthwhile to try though: You could turn of the feed to the grid for a while and turn it back on after some time to see if this changes anything.
KhunLA:
Unfortunately, data is going to and stored on the Huawei server, the graph is updated every 5 minutes. Of course, the arrows also show direction of feed, but not in (real) real time.
I intensely dislike having my data in China, but what can I do ? This is one thing about Huawei...
