Considerations for Choosing a Backup Power Generator for Your Home

With power outages from storms and wildfires on the rise, 2026 is the year to safeguard your US home. Before you invest in a backup generator, discover what really matters—from fuel sources to local regulations—so your family stays comfortable when the grid goes down.

Considerations for Choosing a Backup Power Generator for Your Home

A home backup generator decision is easier when you treat it like a planning exercise: decide what must stay on, confirm the electrical load, then match that need to a generator type and fuel you can reliably use. In the United States, your choice will also be shaped by local codes, the availability of natural gas or propane delivery, and whether you want a permanently installed system or something portable.

Understanding Your Home’s Power Needs

Start by listing the circuits and devices you want to power during an outage, separating essentials (refrigerator, sump pump, basic lighting, internet equipment, medical devices) from comfort loads (central air conditioning, electric range, EV charging). Add up running watts and account for surge watts, which are especially important for motors and compressors. Many homeowners find that an “essentials-only” plan allows a smaller unit and simpler wiring, while a “whole-home” approach requires a higher-capacity system and careful load management to prevent overload.

Types of Generators for American Homes

Portable generators are typically moved into position when needed and can power devices via extension cords or a dedicated inlet connected to a manual transfer switch. They can be flexible, but they require hands-on setup and safe placement outdoors. Home standby systems are permanently installed and connected to an automatic transfer switch; they can start automatically when utility power drops. Inverter generators (usually portable) are designed to produce cleaner power, which can be useful for sensitive electronics, and they tend to manage engine speed more efficiently at lighter loads.

Fuel Options and Availability in 2026

Fuel choice affects runtime, storage, maintenance, and how resilient your plan is during regional disruptions. Gasoline is widely available but degrades in storage and requires safe fuel management; it can also be hard to obtain during widespread outages. Propane stores well in tanks and is common for standby systems, but refills depend on delivery access. Natural gas can be convenient for homes already connected to a utility line, though major events can still affect distribution in some circumstances. Diesel is often used for higher-duty applications and longer runtimes, but it has storage and cold-weather considerations.

Installation

For anything connected to your home’s electrical panel, plan around safety and code compliance from the beginning. A transfer switch (manual or automatic) is the key component that prevents backfeeding into utility lines, which can endanger workers and neighbors. Placement matters: engines need ventilation and must be positioned to reduce noise impact and keep exhaust away from doors, windows, and intake vents. Expect permitting requirements in many jurisdictions, and for standby systems, additional coordination for fuel plumbing, clearances, and inspection.

Cost is often the deciding factor, and it helps to separate equipment price from the installed, ready-to-run total. Typical U.S. costs vary widely based on capacity, fuel type, sound level, and whether you need panel upgrades, trenching, or gas work. The examples below reflect common market ranges for well-known manufacturers and are meant as orientation rather than a quote.


Product/Service Provider Cost Estimation
Portable inverter generator (around 7 kW class) Honda (EU7000iS) Often about $4,000–$6,000 (unit only)
Portable dual-fuel generator (around 9–12 kW class) Westinghouse (WGen series) Often about $900–$1,700 (unit only)
Home standby system (typical whole-home range) Generac (Guardian series) Commonly about $5,000–$8,000 (unit only); installed totals often higher depending on site work
Home standby system (whole-home range) Kohler (RESV series) Commonly about $6,000–$10,000 (unit only); installed totals often higher depending on site work
Home standby system (whole-home range) Cummins (Quiet Connect series) Commonly about $6,000–$10,000 (unit only); installed totals often higher depending on site work
Home standby system (whole-home range) Briggs & Stratton (home standby line) Commonly about $5,000–$9,000 (unit only); installed totals often higher depending on site work

Safety

Safe operation is non-negotiable. Carbon monoxide is a leading hazard: portable units should run outdoors only, well away from openings, and never in garages or enclosed patios. Use battery-powered CO alarms as an additional layer of protection. Electrical safety is equally important—avoid “suicide cords,” use appropriately rated cables, and rely on transfer equipment for home connections. For standby systems, follow clearance requirements, keep vegetation controlled, and schedule periodic maintenance so the unit starts reliably when needed. Finally, plan for safe refueling: shut the unit down and let it cool before adding fuel.

Choosing a backup power generator for your home comes down to matching real electrical needs with a setup you can fuel, maintain, and operate safely under stress. When you size thoughtfully, select a practical fuel, and install with proper transfer equipment and code compliance, you end up with a backup plan that is both dependable and easier to live with over time.
