   I suppose you meant to recommend Generac. They say memory is the   
   second thing to go as we get older.   
      
   Like 'ads' I have enough battery + sine UPS power to last through the   
   night, and long enough the next day to shovel a path through the snow   
   to the generator and woodshed. If I cram the food into the DC-powered   
   freezer the batteries should last 2-3 overcast days. Naturally I'd   
   store food in the snow during the day and the car overnight (animals)   
   if the weather permits but the plan doesn't assume it.   
      
   I can't recommend the obsolete and rare APC 1400 Smart-UPS that I   
   acquired free-for-the-fixing at a flea market to anyone assembling a   
   new backup system and haven't found a reasonably priced alternative   
   that can start a refrigerator, especially one with a lower   
   self-consumption or load sensing turn-on capability. The APC responds   
   to serial port turn-on and shutdown commands when on AC but not on   
   battery.   
      
   I'm trying to design a solar backup system that is safe, relatively   
   affordable and doesn't require a degree to assemble and use, though   
   the experimental arrangement I have now fails the last badly. So far   
   this under-$100 30A MPPT controller looks good.
