One or more. If more than one they would be wired in parallel for capacity.

Example would be a house bank consisting of 3 batteries.

It is refering to the batteries in the bank. There is no hard and fast number of batteries, or even style or voltage. If golfcart type 6v batteries are used they must be hooked up in series to give 12 volts (for most inverters, some really heavy-duty ones are 24v, but not normally), or paralell if 12v batteries are used. Naturally, the more batteries your bank has the longer inverter will run before shutdown. For an inverter heavier than one of the little 1,000 amp units where load is plugged directly into front of inverter, higher numbers of 6v are prefered because they are still higher in reserve time and amps than an equally sized 12v. It takes approx 6 group "2GC" 6v golfcart at approx $80.00 each to equal 2 group "8D" (the size used to start a D6 CAT) at over $300.00 each in a deep cycle version.

If you go to West Marine's online catalog, all their excellent tutorials are available free of charge. Greatest source of basic information on batteries,onboard chargers,inverters,solar,alternators, rope, and many other topics in the world,,,,just shop around before you actually BUY anything!

Already:

I wont purchase these till next season IM sure, I will looking for the info that will give a complete set-up,: batt size, type & #, along with the size of inverter, and the proper regulator for my solar panels, my panels (2) put out the 15 volts or so,

this being our first season and we dont go out for more than a night, I assume once I see how long we will go out for will determine most of the above.

the set up I would look to get would need to cover our house lights, head use, maybe tv, for overnight use, generally a small fan, everything else runs on propane

do you see any real advantage of an on board charger when you have solar panels,
as the dock power could keep that unit going during our outting season, we are only 20 minutes from our marina

I'm a big solar advocate BUT:

If you have an onboard charger and you aren't away from shore power more than a weekend, I would consider solar panels a waste of money. Figure out what your power requirements are, and install enough batteries to handle the load for say 4 days (to be safe). Then a good charger to charge them up during the week.

You can buy a whole lot of batteries (and a charger) for the price of one good solar panel. You're going to need the batteries anyway, so you can install them first and then look into solar panels and controllers later, IF you still want them.

Until you can come up with a good estimate of your load, everything else is a waste of time.

Can someone address the implications of powering, say, a tachometer from the house battery (or battery bank) when the tach is also connected to the engine's coil which is a separate electrical circuit (ie, house battery and engine battery not wired in parallel)?

Like, WHY???? It might work on an outboard with a magneto, but I honestly don't know.

Try it and let us know!
