way too high or low values

[MAPSOFT2]

In my configuration (Home Assistant 2023.2.3, "deye_sg04lp3.yaml", "Deye SUN-8K-SG04LP3-EU" with a logger serial number starting with "23" ) ... I receive (or at least they are shown) way too high or low values.
Often it is in the morning or evening but yesterday they continued the whole day and night through.
Way too high values happen mostly for DEYE PV1/2 Power (DEYE Total Load Power) and sometimes for DEYE PV1/2 Current.
Too low Values happen mostly for DEYE PV1/2 Voltage. In the history graph they are shown as 0V.
Since P=U*I ... I suspect that the Power is calculated and the Voltage drops to values between 0 ... 1V
and is used with decimals e.g. a value of 0.1V
Does the DEYE or the home_assistant_solarman calculate the power?
Why are these way too high/low values there in the first place?

Thanks for reading!
