But what iam also concerned about is say at 11.5 battery volts what kind of inverter voltage am I receiving?
Will it(inverter) still make 110V at 11.5 input?
Yes the inverter will make 120vac just fine down to 10.0 volts unless it shuts down earlier.
The 120vac does not taper off. The inverter pulls increasing amps to make up the difference and apply constant 120vac.
There will be no harm to the fridge. Food will get warm however.
If you have an on-board generator consider an autostart set to about 12.1 volts.
