No solid solar output

I continue to struggle with not having a continuous power output, which is an ongoing issue since May. I used to see a nice curve with little interruptions, but somehow not anymore. Nothing has changed in the system, and so far, I have not received much help despite talking to support several times. Clear skies all day today, and as most days, at around 11:30 the system starts to fluctuate a lot for most of the remaining day, for no reason. We have nothing that should influence the solar production around that time of the day, no shade whatsoever, all panels in full sun. (2x flexboss 21, 1x gridboss, 3x outdoor wall mounted batteries)

I might sound obvious but with your +7kW output from PV array it might be not "consumable". How it is related to your power consumption (also 7kW-ish continuously?) the PV array will produce power ONLY when there is demand for it. So if your consumption doesn't match the potential PV array production you will get only as much as you consume from the array.

Just my 5 cents.

Oh, I have lots of consumption as I have 3x batteries that total 45kw, I also sell back to the grid, so there is no real limit on where the power can go/ Interestingly, every time I reset both inverters, they behave normally for several hours before going bonkers again. This is also just one inverter; in total, I have 19kw solar panels across 6 strings and two inverters. Both inverters show the same behavior.
