What to plan for in Lihue

  • Lightning (relatively high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
  • Landslides (relatively moderate): Decide what must stay on and size backup to that.
  • Wildfires (relatively moderate): 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.
