Has anyone experienced the boost/step up causing phantom drain on the battery in a car?

Yes this will drain battery. You need to install a switch when it is not in use. I just bought a 36v Golf cart and the batteries were dropping voltage when sitting. Come to find out the reducer was draining battery voltage even when there was no accessories on.

Will this work to protect a 12v to 12v battery charger if mounted between a 12vdc (20.48v actual out put) generator and the charger? All on a 8a fuse.

The regulator is not performing as advertised . If the power is kept below 25 volts then it works fine but at 30 volts it acts like an SCR has fired and shorts out the PS , some form of current shunting occurs . Honda 4 magnet flywheel roters can gen. a little higher voltage .2 magnet flywheel such as on a Kawasaki 12 hp or similar may gen lower voltages . You must us a dc input ,rectified and filtered .

Can i send 12v ac as an input or does the input need to be dc?

DC only. This is a DC-DC converter. If you want to do AC, it's best to get a transformer.
