Cw I admire your attitude but really now, 2 days without food & water (you have no water without power to run the pump - can't even flush :-( of course your wife will be in town at a motel for the first couple of outages before she moves out permamently! Then there's the frozen plumbing & broken pipes, potentially overflowing sump pump etc... Face it you're now in the market for a generator.
At our country home we have an 8 horsepower 240VAC (for supplying both phases) ~5kW generator on hand including a days's supply gasoline stored with PriG fuel preservation additive. This is enough for the furnace, refrigeration, water pumps, lighting, and outputs a clean enough sinewave for the audio rig. Of course I use AC-line primary lightning surge arrestors & audio system AC power conditioning with AC surge protection anyway, but if running on generator power the additional line-filtration is mandatory not only for noise-reduction but also for protection against back-emf transients generated when other loads in the house connect & disconnect.
Mine is manually connected to the mains via a special cable & backfeed-outlets that I fabricated & installed. Of course you must first isolate your house from the distribution grid via an outside disconnect (breaker or knife switch) before backfeeding with your generator. Install mains-monitoring neon indictor lamps on the line side of your switch so you'll know when commercial power is restored.
Most generator owners keep a conservative but adequate setup on hand like mine. But you can go for electric starting, higher wattage (probably you would need to have a larger unit than mine to run a current-hungry rig like that - make some measurements with an amprobe instrument for proper sizing). Some generators can be fueled from methane (if you have natural gas service out there) or bottle-gas propane, eliminating fussing with gasoline & refueling issues.
An AC line transfer-switch is another step up. This can be done manually via 2 knife switches, or automatically via an optional transfer relay box available from better generator suppliers (Onan, Kohler, etc). The best systems have electric starting & are always on standby ready to run when power goes down. The transfer switch automatically places the load online typically within 15 seconds or less of startup, then retransfer when power is restored & shut off the engine after a cooldown interval.
