We tend to take rather long trips. One is impending which will allow us to miss at least some of this summer's hottest weather.

While our power is generally very rubust, this is also the season with the highest probability of electrical brownout and blackout issues.

Something which worked well during an extended blackout after hurrican Sandy a number of years ago was fill in spare space in my refrigerator's freezer with plastic mineral water bottles. This keep our refrigerator cold for about a week and hopfully add enough thermal inertial to bridge a power problem of reasonable length.

It may be helpful that my freezer section is above the refrigeerator which I'm guessing aid by convection when the internal fans no longer function.
