The single "cool string" is being hammered pretty well with your present usage and a second string is really needed (for loads/65% discharge overnight/high charging current).-Bill
The so called "hot" battery bank is now offline while I try and bring up the two batteries that were low on SG.Those around 50A are going to the online good string of batteries that have 225Ah @48V.gicamuci means "Gică" (a name, much like George in English) plus "muci" which means snotty (in English, mot-a-mot), but I am using is more as "novice". So something like "novice George". I was born, raised and lived in Romania until I turned 30. So that's a Romanian "thing" as my name is not George, but Alex.

Your problems stem from using battery strings and not doing the full
maintenance. Not bad for a first set so do not take it wrong.
My conclusion is that I have an energy production which is too big for the battery bank I have (or I need a bigger battery bank). During daytime our house pulls somewhere between 15A to 20A. Plus the charge rate recommend for my 450Ah battery bank (45A) it gives me some 60A or 65A for the limit I should use on the FM80 with the whole battery bank in service. Did I get it right ?
