Can an alternator be to big?

I have been offered a really good deal on a high amp (325 amp) fire engine alternator by the city vehicle maintenance shop. It was purchased as a test unit but due to some budget cutbacks ended up being to expensive to equip the whole fleet. This monster is hot rated at 200 amps at 2,000 rpm and 275 amps at 4000 rpm. I am thinking about buying it and keeping the 200 amp Leece Neville as a spare. My battery bank is 850AH of L16HC wet cells that can take 200 amps in bulk charge. Is my Xantrex smart regulator going to keep this monster from cooking my battery bank? A smart regulator should have no problem at all with an over-size alternator. In the end, the battery itself will determine the rate at which it will accept charge. With so large a bank and so ample an alternator, a soft-start feature on the regulator will add life to your belt(s). And belts and slippage may also limit charging current.
