Essentially I'd have a 5-gallon water tower such as the Fetco I mentioned that would be constantly drawing power to keep the water hot. I'm not talking bringing individual cups to a boil, just heating the water initially, taking some for a cup periodically from the reservoir, then replenishing the displaced water with fresh (cold) water from a water storage container.
I'm skeptical about the power draw too, and it'd be an expensive experiment, so any feedback from people who understand electronics more than I do is welcome. I was looking at a pair of Kinetik 1400 cells plus a Power Bright PW2300 DC inverter.

I (assuming I understand him correctly) believe the OP is wanting a pour over station. Doing a large air pot at a time, yes, brewing just off the boil makes sense, but doing that for every cup does not. YMMV of course.
Actually, I had EXACTLY pourover stations in mind . . . every stand I know with a 5-/6-cup pourover station boils water on a propane stove . . . two kettles, etc., etc. -- seems to work fine for them! ;^)

One thing that's always worked well whenever I've seen it in use is to use cards instead of numbers on the pourover station. For example, instead of telling the customer that their cup is in the #1 space, or the #4 space, you can use picture post cards of (e.g.) the Golden Gate Bridge, Coit Tower, Alcatraz, etc. -- Your cup in on the Bridge, and so on. You can also change the cards frequently (say, once a week or so), and the regulars actually set into it -- wanting their cup to be "on Candlestick" instead of on "AT&T Park," or "on City Hall} instead of "on Pier 39," and so on . . .

Well, just heard back from Fetco and they say they can only recommend running their products off of AC. Makes sense that they wouldn't want to suggest doing something that could expose them to unusual technical support situations. Hmm.
