I have the same system I struggled with this a bit myself. I wont get into my use case as it is very specific to a marine installation.
In the end I realized it is of little concern, here is why:

I use the battery app to monitor over all health and cell balance other than that I do everything from the Inverter.
I set the BMS to 10% SOC low disconnect or if any one cell hits 5% (3.00...
People keep insisting that a battery charger provides effective "isolation transformer" this is simply not true in most modern battery chargers.
If you have an older heavy marine charger with a real 120/12 volt transformer yes.
But the multi frequency/multi-voltage chargers today often do not...

Good solution if you wanted to go the all on battery/inverter route. Even a large battery charger would only be around 600 watts (12V x 50A).
Since the batteries/inverter are handling the house peaks the charger would catch up in between. Even I could find space for a 600 watt...
I understand they are a industry focused group not DIY friendly.
There are two ways you can gain access to all the standards.
Select a "trial membership" they allow full access to the standards I think it was two weeks.
I downloaded all the areas I was interested in. A28, E2, E11, E13, H2...
