Wrong Data from Inverter?

[Andurilll]

I don't get it... I maybe have wrong Data from the Inverter. But i am not shure. Can you controll if i am just dumb or if something is Off:

This is the Inverter Dashboard in Fusion Solar. Exactly when my battery is full, the Input graph of the PV gets smaller around 1 kW. Before i had the battery, it was smooth and had usually not this Big values change. Only when it was cloudy/sunny.
The Same is visible in Homeassistant:

This was the weather

Anyone can Spot the error? Or is this the weather? Do the Battery load somehow add in the Inverter?

This is discussion about integration of Huawei Inverters into HA, and not really helpdesk for Huawei PV Systems, so your post is quite of topic...
But anyway, it looks like you have active power limiting set up in the fusion solar.. Check what entity Device state shows during the day.
