Is there such a thing as too many breakers?
#3
You could do a regular breaker for each 7s pack for easy pack isolation & extra safety.
General consensus for a small to medium system would probably be one overall shunt trip controlled by the BMS at the combined battery positive for whole system shutdown.
Large systems like daromer is running might have more sections to it.
Charge controllers & loads (inverter, DC systems, etc) connect on the other side of the shunt trip from the battery positive (ie so both charging & discharging is disconnected for a battery issue (cell high/low) or high current).

Any wiring on the mains 240/220/110 side if the inverter should be per local electrical standards.
