What to plan for in Sumter
- Strong winds (relatively high): High winds knock out lines on ordinary days. A battery or portable power station handles the common short outages; add a generator for multi-day repairs.
- 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.
- Hurricanes (relatively moderate): Hurricanes can mean a week without power. A standby generator on natural gas or propane, or a battery with solar, beats a stack of gas cans; check flood height before you site equipment.
