Today I changed the inputs, I will see how it will be.

In the attachment there are charts of a perfect day.
Please give me a hint

in the case of partial shading, it improves the search for the maximum power point by scanning according to the set time

from these reports you can see that you have at least one bit0 error, in fact, ID01 AC voltage too high, the display should be visible and saved in the memory, you had shutdowns 8:40, 9:58, 13:44, 15:13 and maybe more, so a lot and the fault here is not the inverter which reacts correctly and turns off after a few minutes at 253
you would need an electrician with a measuring device, measure at the connector, inverter and compare with what the inverter sees and then think what to improve
when he jumped on over 8kW What parameters should I give from the possible SOFAR charts ??

Today I noticed this type of behavior and after entering the list of events it turned out that I had ID01 several times, i.e. too high voltage of the network. My house is the last one on the power line and it probably gets such peaks from time to time, and my neighbor also has PV installations nearby, so probably when the sun is bigger, his voltage also increases. I don't know if there is any option to do anything about it?

Do you see these errors also in the solarman?

except that in the beginning it was normal and the AC voltage was normal. Why is the inverter not throwing an error and saving nothing, why is it turning off? For a week now, I have made a preview to see why. Unfortunately, the meter shows that AC and DC are normal. Should I advertise the inverter and on what basis ??
How to read this error from writing ?? So the problem is on the side of the Energa supplier and not PV ??
The inverter does not turn off on cloudy days, and the AC voltage is irrelevant to the weather. Attached are photos from the last "worse" days. And on 14.04.2020 the weather was better and it turned off,
when he jumped on over 8kW What parameters should I give from the possible SOFAR charts ??

I had the firmware version 2.01, now I do not have the upgrade to 2.20, but it was worth sacrificing the Polish language because it no longer cuts off the production at ~ 8kW.
ps. I have the 8.8KTL-X model

Did you update?
The effect is immediate, yesterday and today the peak output broke 8.8kW:

I could draw such an erroneous conclusion from my colleague's statements so far ... very professional by the way.
