Looking at a 28' cruiser (1996 and newer) and most seem to have AC/Heat.

How does the Ac/Heat run when away from the dock and under way (engines on). Some specs I've seen mention an inverter. Do you have to have this in order for 110volt items to run when the engine is on?

Some mention invereor and battery charger.

Is an inverter a standard item for the most part when a vessel has AC/Heat in this category (1996 and newer)?

Is an inverter and battery charger a one in the same type device?

I understand that you need either a generator or shorepower when engines are off, just confused about how things work with engine power.

==========================================

Inverters are usually not a standard item and are almost never used to
power air conditioning.

In order to run your A/C from an inverter you would need both a very
large inverter and an even larger alternator. In actual practice it's
almost impossible and virtually no one does it. Your best bet would
be a generator but 28 ft is a bit on the small side for that. The
only other alternative would be an engine driven compressor similar to
what is in an automobile but that would be a custom installation
rarely seen on boats.
