Alternator & argodiode - where is the reference voltage?

I have a Volvo Penta D6 which includes a 150 amp VP alternator. This feeds a Argodiode 180-3AC. A recent voltage measurement showed 14.77V on the input side and 14.45V out to the 3 battery banks. Clearly the compensation is working.

My question is this. Who in the system is responsible for regulating the voltage? I presume the Argodiode is only monitoring the voltage drop. This implies the alternator has a voltage it is working to, perhaps 14.4V, but is designed so it can be 'influenced' to go a little higher by the compensation terminal. Do I have this correct? Is 14.4V a standard output?

Thanks.

you will need to take the reference voltage for the alternator from either the house or the starter battery, this will overcome the volt drop in the diode module.
