This is what I pointed out to you, that you had a cell failure. I don’t know one or several. Also, you need to correctly form telemetry widgets, for more detailed information, three in a row (MP DC input voltage, BMS DC voltage, BMS cell voltage difference) with fixing the problem point and displaying the bus values. Well, the meaning of your BMS settings. Learn to fill your questions with expanded information, then you will receive more expanded answers. Crystal ball divination is inappropriate here.
UPD: For now I can state that all your inverter and ESS assistant settings are taken from space. The values are not calculated.
Here is an example of calculations in a similar topic, read it carefully.
This is not for copy-paste, all settings are individual.
But the principle itself is clear.
