It is not that hard. All that you need is a generator capable of turning the motor and a few relays on your furnace and running your heaters and return pump -1000 or 1500w could probably get this done. If you can do this, then you can keep your tank warm and oxygenated... which can get you about a week before the corals start to miss the light.
If you are out for long in the winter, then you will need more heaters than normal to keep your tank warm if your house gets cold (unless you have like a 300W heater in a biocube, or something). Gas furnace will not need much power. If you have an electric furnace, then you will need a very large generator and a more complicated solution.
You can keep the tank running with extension cords, but if you don't want to pig-tail the furnace, then you might need a back feed somehow.
Auto transfer switches, microwaves and TVs are all not necessary, but still might be useful. Only you can decide.
If you are in an area where disaster could hit (fires, floods, etc.), then a very solid, large system with an ATS that runs on LP with a 500 gallon tank could be for you.
