One thing to watch out for if you use a generator some do not give a nice clean AC and are not good for electronics...Honda is super and pretty quiet, you might be able to set it a ways away from the board and get by on the noise....of course it would have to be outside.

One other option in an inverter setup, using a large deep cycle Marine battery. Use a small cart to setup the power station, inverter and battery. Quiet, and would last a while....
