Growatt SPF 5000ES AC input and Battery voltages fluctuation while charging problem

Hi guys,

When feeding the inverter from GRID, a strange behavior happens, a video is attached for clarity. The voltages for both AC input and DC battery are fluctuating obviously.

This issue does not happen when charging the battery from solar input.

I have checked the internal components, there are lot of humidity affecting the traces. However, seems like no traces are broken

I tried to replace 330K resistor series at AC voltage sensing, but not fixed.

NOTE: in video, the Grid voltage should be 230V

Does anyone have idea about it?
