A power outage during a storm isn't just an inconvenience — it stops your sump pump, spoils your food, disables medical equipment, and leaves you without heat or AC. The right backup power system changes all of that. Here's every option, clearly compared.

2. Standby Generators

Generac Guardian 22kW Standby Generator
22kW powers large homes completely. Includes 200-amp whole-house transfer switch and WiFi monitoring via Generac Mobile Link. Runs on natural gas or LP. Professional installation required.
3. Solar + Battery Systems
A home solar + battery system (like Tesla Powerwall or Enphase IQ Battery) stores energy from solar panels and provides backup power during outages — silently, automatically, and without fuel. The highest upfront cost but lowest long-term operating cost.
How It Works
Solar panels charge a battery bank during the day. When the grid goes down, the system automatically switches to battery power. Modern systems can power an average home for 12–24 hours on a full charge — longer with continued solar generation.
What It Costs
A Tesla Powerwall 3 with installation runs $12,000–$15,000. A full solar + storage system runs $20,000–$40,000 before the 30% federal tax credit. For homes in sun-heavy regions with frequent outages, the economics can make sense over a 10-year horizon.

4. Portable Power Stations
Portable power stations are large battery packs that power devices and small appliances silently and without emissions — safe for indoor use. No fuel, no CO risk, no noise. The right choice for apartments, HOA communities, or anyone who can't run a generator.

5. Generator Safety
- Never run a generator inside — including garage, basement, or carport with door open
- Position at least 20 feet from windows, doors, and vents
- Install battery-operated CO detectors on every level
- Never refuel while running — let it cool 15 minutes first
- Use a transfer switch — never backfeed into your panel
- Point exhaust away from your home and neighbors
