charging house battery

I have a 2014 Thor Chateau, after replacing the isolator solenoid the battery charges while engine is running. Battery charges when plugged in to shore power, also when generator is running. My question is what protects battery and other parts of system if driving and running generator (for AC) at the same time ?

Thanks in advance

When it is not possible to access 120 volt power, the 12 Volt system functions can
be supplied by the auxiliary batteries. The chassis battery is protected by a battery
isolator controller to prevent discharge from excessive electrical consumption when
the motor home is not running. The auxiliary batteries are recharged by the power
converter when the motor home is attached to an outside 120 volt power source, or
by the generator when it is running, and by the chassis alternator when the chassis
engine is running.
I hope this helps page 75 on the owners manual
