Pylontech US2000 x2 && Multiplus II - SOC never reaches 100%

Hi, any explanation why my two US2000 do not reach 100% even if at 3pm the excess of PV-generated energy already goes to the grid. Is this normal/on purpose.
Typically it ends at 99% - but never goes to the final 100%

Thanks if you have an explanation or idea why it behaves like this

This is quite a common observation of Pylontech users.

I have a set at home the same was true for almost two weeks, but they do reach 100% most days now. It has nothing to do with not enough solar but cell balancing, especially passive balanced systems. No all that uncommon in managed lithium batteries.

So don't stress too much about it.
