"Hello community,
I'm experiencing a strange behavior with my inverter. On sunny days with high PV output, the PV power drops significantly when there's grid consumption. You can see this clearly in the screenshot. The yellow line represents consumption and the black line represents PV power. Is this just happening to me?"

It's not unusual to see drops in peak output with clouds or shading effect - have you ruled that out?
It is possible your inverter is tripping when exporting because the grid voltage is going too high - do you see any alarms or error messages for that period ? - If you look at Foxesscloud in the Inverter Details, in the empty graph at the bottom you can select RVolt, SVolt, TVolt sensors and that will show you the voltage for the day - and highlight the peaks - does that look to be high when the PV output falls ?
