After replacing the strings 0.5A on average less PV2 and these zeros !!!

Here is yesterday's graph, pay attention to the lower peaks, the fact yesterday was snow showers, peaks down the norm, although the installation next door was doing better, but WHY? one peak is a peak with zeros even in mains voltage ???

When I have a break in the transmission, it writes that it is offline, and not that I can enter the inverter and watch it show 0.
Besides, the biggest disadvantage for me is the 0.5A difference because it is always about 150W

It's not ok. If you extract the interesting parameters, you can see that there are at least three high AC shutdowns

Pay attention to what is happening before the zeros, for example the one on 26.04. 11:43 Uac voltage 254.6 and further 11:48, nap. Udc 301.8 went up because the inverter stop and the load dropped and the current Iac 0

Then why doesn't it crash an error ???
see the attachment, voltage even 257V, but the production is still there, not everything.

Udc is the voltage on PV1 or 2?
Even if the voltage of 301.8V is not a reason for switching off, besides when it turns off the inverter for some reason, you can still observe the data, e.g. how it turns off because the PV voltage is too high, the voltage shows, as well as the rest of the parameters and the error.

Added after 8 [minutes]:

On the neighboring installation on the same day also mega high voltage, also zero productions but never everything at 0
From the beginning, voltage above 250V on both installations at peak, what to do with it, because it is getting worse.

You need to know what are the upper parameters and their duration for the inverter to turn off.
I would like to remind you that the inverter does not turn off for the reasons given by you and does not generate an error code or even warnings, such as for the second installation. But maybe this one doesn't have such a function.
And once it turned off because of too low mains voltage and / or too low mains frequency.

How to do such a reading?

And when reading the errors, you change the column for today or not leave it as standard now and you can not see the errors

the inverter at longer moments above 253V will turn off if it is correctly configured

As standard, in the Sofarze, you can change the recording frequency from 5min to 60s. This is the shortest interval that Sofar offers by default.

Familiarize yourself with the threads that I am promoting.
