100 hour 4D sounds very small. Those batteries are usually about 200 ah. You mention that the "generator alternator" is 50 amps, but i think you mean that the generator output is 50 amps? That would indicate that you have a 4.5 or 5 kw generator? The generator can run your AC all night, but you can damage your generator if you run it lightly loaded. Generators like to work.
