What to plan for in St. George
- Lightning (very high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- Wildfires (relatively high): Wildfire risk can mean planned shutoffs and smoke. A battery charged by solar gives quiet backup, and fueled generators need extra care on dry days and clear space around them.
- Landslides (relatively high): Decide what must stay on and size backup to that.
