What to plan for in Missoula
- Cold waves (relatively high): Cold waves raise demand and can cause both outages and frozen pipes. Keep at least one room warm with a battery-run heater circuit or a generator.
- Avalanches (relatively high): Decide what must stay on and size backup to that.
- Ice storms (relatively high): Ice storms bring down lines for days. A standby generator with a transfer switch, or a battery sized for the fridge, furnace blower and well pump, matters more than a small power station.

Out of direct afternoon sun, in a spot the maker approves. Heat in Missoula (about 150 cooling degree-days a year) is the main limit.
