where I live the power goes out somewhat often, but usually for less than an hour or so. I am having an M55 installed next month and I am concerned about the power going out while I am at work then the house filling with smoke causing the alarm company to call the fire dept. Do you guys think this would work well as a backup power supply ? Or is there a better solution ? http://www.northerntool.com/shop/tools/product_200465190_200465190 great site by the way, all the info here really helped guide me when I was buying the stove.
