What's an inverter? My main concern when the power goes out is the sump pump in my finished basement........I've considered buying a small gasoline powered generator but haven't gotten around to it.
An inverter converts DC power to AC.. You can hook it to a 12v battery..
But, years ago when the snow melt started flooding the basement, he did a similar hose rig and it worked fine, so....
Maybe it's my cynicism, but I'm just not that worried. I think this storm is at least 75% hype.
Check the auto parts dept. at Wallymart or other automotive supply. They are used to convert 12V DC to 120V AC for stereos in cars.
Check the wattage on the sump pump and buy a big enough inverter.
