To fully charge 8 - 12 volt utility batteries in a reasonable time, and approx. how long would it take. please give a few examples with different sized generators. THis generator will be used as a back-up with a wind mill, solar panels and a small hydro generator.

Get the ampere-hour capacity of the batteries off their label. Suppose that it is 50 ampere hours for each, and you want to charge them within ten hours (which is slow enough to not damage them). Then you will need 5 amperes, times 96 volts, which is about 500 watts. Since the smallest such generator you can buy is rated at something over 1000 watts (3000 is common), any one you buy will do the job. You will need some sort of rectifier assembly to do the actual charging.
