Hurricane Season Home Backup Power Checklist 2026
Hurricanes can leave homes without electricity for hours, days, or even weeks. A hurricane generator can keep refrigeration, lighting, medical equipment, internet devices, and other essentials operating while utility crews restore service. Portable gasoline or dual-fuel models are practical for smaller budgets, while inverter generators reduce noise. Standby systems provide automatic whole-home power, and solar generators offer quiet battery backup without fuel or exhaust. Choose based on your wattage needs, budget, and likely outage duration.
What Is a Hurricane Generator?
A hurricane generator is a backup power system that provides electricity when the utility grid fails during a storm or outage. Depending on its size, it can power essential items such as refrigerators, freezers, sump pumps, lights, fans, Wi-Fi routers, phone chargers, garage-door openers, and important medical equipment like CPAP machines or oxygen concentrators, as well as refrigerated medications.
Before choosing a generator, decide which devices must run continuously and which can be used only when needed. An essential-load generator is usually more affordable and powers selected appliances, while a whole-home generator connects to the electrical panel, can support more circuits, and may start automatically, but it requires higher installation, equipment, and fuel costs.
Hurricane Generator Types Compared
Each generator type serves a different outage scenario. Portable units offer flexibility, standby systems provide convenience, and battery-based equipment delivers quiet, emissions-free power. For homeowners looking for a home battery backup solution, battery systems can provide reliable support for essential appliances during outages.

How Many Watts Do You Need During a Hurricane?
To size a generator correctly, distinguish between running watts and starting watts. Running watts are the electricity an appliance uses continuously. Starting watts are the temporary surge required by motor-driven equipment such as refrigerators, pumps, and air conditioners.
Read appliance labels and manufacturer specifications rather than relying only on general estimates. Add the running watts of equipment you expect to use at the same time, then account for the largest starting surge.
Common appliance and equipment power needs
Approximate requirements vary by model, but these examples can help with planning:
-
Refrigerator: about 100 to 800 running watts, with a higher startup surge
-
Freezer: roughly 100 to 500 running watts
-
Sump pump: approximately 800 to 2,000+ starting watts
-
Window air conditioner: about 1,000 to 1,500 running watts
-
Lights and phone chargers: usually 100 to 300 watts combined
-
Wi-Fi router and modem: approximately obviously 10 to 50 watts
-
CPAP machine: commonly 30 to 100 watts
-
Well pump: often 1,000 to 3,000 or more starting watts
A simple generator sizing process
-
List the appliances and devices that must operate.
-
Record each item’ s running and starting wattage.
-
Add the running watts for the loads used together.
-
Add the largest relevant startup surge, not every surge automatically.
-
Choose a generator with extra capacity for safer operation and future needs.
Avoid running a generator continuously at its maximum rating. A reserve of roughly 20% can help accommodate startup demands and unexpected loads.

Compare total ownership costs: Include installation, maintenance, fuel, accessories, and possible upgrades when comparing options.
-
Consider expandable systems for future needs: A modular design can be useful if your power requirements may increase over time. The Anker SOLIX E10 Whole-Home Backup is an example of a system designed with modular expansion in mind, allowing homeowners to expand their backup setup as their energy needs change.
-
Check installation and compatibility requirements: Make sure the system works with your home’ s electrical setup and meets local installation requirements.
By planning around your current energy use and future needs, you can choose a backup system that provides reliable protection without investing in unnecessary capacity or features.
Hurricane Generator Safety Rules You Cannot Ignore
Generator safety must come before convenience or power output. During hurricanes, improper generator use can cause carbon monoxide poisoning, fire, electric shock, backfeeding, or injury from rain and flooding.
Use the following safety rules before, during, and after operating a generator:
-
Prevent carbon monoxide poisoning: Always operate fuel-burning generators outdoors, at least 20 feet from the home, with the exhaust pointed away from doors, windows, vents, garages, porches, basements, crawl spaces, and other enclosed or partially enclosed areas. Never run a generator indoors, even if doors or windows are open. Install working carbon monoxide alarms on every level of the home and outside sleeping areas. If wind pushes exhaust toward the house, shut the generator down and move it to a safer location before restarting.
-
Connect appliances and home circuits safely: Use outdoor-rated, heavy-duty extension cords that match the generator’ s output. Inspect cords for cuts, damaged insulation, loose connections, or overheated plugs before use, and place them where they will not create tripping hazards or sit in water. Never plug a generator directly into a wall outlet. This dangerous practice, known as backfeeding, can energize utility lines and seriously injure or kill utility workers. Use proper cords for individual appliances, or have a licensed electrician install an approved transfer switch.
-
Handle fuel safely and never refuel a hot generator: Turn off the generator and let it cool before adding fuel. Refueling while the engine is running or hot can ignite spilled gasoline or vapors. Keep gasoline and propane away from flames, pilot lights, sparks, and hot engine parts. Store fuel only in approved containers and follow the owner’ s manual and local fire-code rules for fuel storage limits. Clean up spills only after the generator is off and safe to approach.
-
Keep the generator, cords, and connections dry: Never operate a generator in standing water, flood-prone areas, or heavy rain without proper protection. Use only a manufacturer-approved weather enclosure or canopy that allows full ventilation. Do not cover a running generator with a tarp or improvised material. Keep cords, plugs, and electrical connections elevated and away from wet ground whenever possible. If water reaches the generator, do not touch it; disconnect power only if it is safe, and have the equipment inspected before using it again.
How to Prepare and Operate a Generator Before a Storm
Prepare your generator before severe weather arrives so you can use it safely and reliably during an outage.
-
Check specifications and test early: Review the owner’ s manual, wattage capacity, fuel type, and oil requirements. Start the generator outdoors before storm season, run it under a light load, and confirm it operates normally without leaks, smoke, warning lights, or unusual noise.
-
Complete maintenance and inspect equipment: Replace oil, filters, spark plugs, and other service items as recommended. Inspect cords, plugs, outlets, tires, batteries, fuel lines, and connections for cracks, corrosion, wear, or loose parts. Use only outdoor-rated cords in good condition.
-
Store fuel safely: Use approved fuel containers and keep fuel in a ventilated area away from living spaces, heat sources, and ignition risks. Store only the amount allowed by local rules and needed for planned use.
-
Choose a safe location: Operate the generator on a stable, level, dry surface at least 20 feet from the home. Point exhaust away from windows, doors, vents, garages, porches, and neighboring structures.
-
Connect power correctly: Turn off unnecessary loads before connecting appliances. Use a properly installed transfer switch when connecting to home circuits, and never bypass safety interlocks. Keep cords away from walkways, puddles, and standing water.
-
Monitor operation and refuel safely: Check for overheating, overloads, low oil, fuel leaks, blocked airflow, hot cords, flickering lights, or burning odors. Turn the generator off and let it cool before refueling. Keep children and pets away while it is running or cooling.
-
Use professionals for standby systems: Have standby generators installed by qualified professionals. Plan ahead for permits, pad placement, gas-line sizing, transfer equipment, grounding, inspections, and scheduled maintenance.
Conclusion
The best hurricane generator depends on what you need to protect. A portable gasoline or dual-fuel model is often the practical choice for refrigerators, lights, communications, and other essential loads. An inverter generator offers quieter, cleaner power, while a battery backup system provides indoor, emissions-free operation for selected devices. For automatic whole-home coverage and long outages, a professionally installed standby generator is usually the most convenient option.
Calculate running and starting watts before shopping, plan your fuel or charging strategy, and prioritize safe placement and electrical connections. A properly sized and safely installed system can make an extended outage far more manageable.
FAQs
Can a portable generator power a refrigerator and freezer?
Yes, a properly sized portable generator can power a refrigerator and freezer, provided it handles their combined running watts and startup surges. Check both appliance manuals, add their starting requirements, and leave reserve capacity. Connect them with outdoor-rated cords or an approved transfer switch, and never overload the generator.
Can I run a generator in my garage if the door is open?
No. Never run a gasoline or propane generator in a garage, even with the door open. Carbon monoxide can accumulate rapidly and enter the home through cracks, doors, windows, and vents. Operate the generator outdoors, at least 20 feet from the house, with exhaust directed away from openings.
Is a solar generator reliable during a hurricane?
A solar generator can reliably provide limited backup power for phones, lights, routers, medical devices, and small appliances when fully charged. However, cloudy skies and heavy rain can significantly slow solar recharging. Choose enough watt-hours for your expected outage, charge it before the storm, and consider another source for pumps or central air.
Can I connect a portable generator directly to my home?
No. Connecting a portable generator directly to a household outlet can cause dangerous backfeeding, energize utility lines, and create a fire or shock hazard. Use individual outdoor-rated extension cords for appliances, or hire a licensed electrician to install a correctly sized transfer switch and inlet box.
