what size of wire should be used to hook up this inverter to the battery bank?

I own this inverter and have sense 2014 i use it 24/7 in a solar set up the manufacturer recommends 2awg which i would recommend 2/0 awg at a 2 to 3 feet cable, (the problem is the voltage drop across the wire lowers the effiecentcy and makes it use more from the battery), if your going to run heavy inductive loads over a long stretch like a hair dryer or small water heater or heater 700 - 1500 watts go with the 0awg its heavy cable yes but this thing can pull upwards of 300 amp. Word to the wise as well do not use Terminals use a power block that has a set screw for tighening like XSCORPION RT00P Dual Ring Terminal with Adapters would be a perfect example.

Will this run if battery volts go below 10.5?

Kisses manual for sw1220 says under voltage shutdown is 10.5 volts reset recovery 11.8 volts.So answer is no.

Does this unit require a 200 amp fuse to be installed between it and the battery?

It would be a REALLY GOOD idea to install a 220A fuse or circuit breaker. I did.

if this is on my yacht, and I have it on while out of dock. Do the engine alternators charge the batteries so that this doesn't run them down?

It depends on your setup. If you have one set of batteries for both the cabin and your engine starting, then the answer is most likely yes depending on whether your alternators wattage is equivelant to the wattage output being used by the KISAE. If you have cabin batteries being charged by solar panels or a wind generator, that are separate from your engine starting batteries then the answer is generally no. You can have a setup that allows your cabin batteries to be charged by either solar, wind generator or engine alternator and then the answer would be yes under the same caveat of wattage in virsus wattage out.
