Home Generator Reviews: Our Top Picks for Reliable Backup Power
Power outages are more than just an inconvenience; they can disrupt daily life, cause damage to appliances, and even pose safety risks. Whether you live in an area prone to severe weather, have essential medical equipment requiring continuous power, or simply value uninterrupted comfort, a home generator offers peace of mind.
Choosing the right generator can be a daunting task, given the variety of types, sizes, and features available. This article will break down the key considerations and highlight some of our top picks across different categories to help you find the best backup power solution for your home.
Why Invest in a Home Generator?
Beyond comfort, reliable backup power protects your home and family in several ways:
- Preserve Food: Keep refrigerators and freezers running to prevent spoilage.
- Maintain Essential Systems: Power furnaces, air conditioners, sump pumps, and water heaters.
- Stay Connected: Keep lights on, charge devices, and maintain internet access.
- Security: Power security systems, garage doors, and exterior lighting.
- Medical Needs: Ensure critical medical equipment (like oxygen concentrators or CPAP machines) remains operational.
Understanding Your Options: Portable vs. Standby Generators
Home generators generally fall into two main categories:
-
Portable Generators:
- Description: Mobile units that can be moved and placed outdoors. They require manual setup, starting, and refueling. Power is typically delivered via extension cords or through a manual transfer switch.
- Pros: More affordable upfront cost, versatile (can be used for camping, job sites, etc.), no permanent installation required.
- Cons: Require manual operation, typically louder than standby units, must be placed far from the home due to carbon monoxide risk, limited power output compared to larger standby units.
- Standby Generators:
- Description: Permanently installed units, similar to an outdoor HVAC unit, connected directly to your home’s electrical panel via an automatic transfer switch. They sense power outages and turn on automatically.
- Pros: Automatic operation (seamless transition during an outage), higher power output (can power most or all of a house), quieter operation than portable units, safer (permanently installed outdoors), fueled by natural gas or propane (no manual refueling needed for long outages).
- Cons: Significant upfront investment (unit and installation), requires professional installation and permits, permanent fixture on your property.
Key Factors to Consider When Choosing
Before looking at specific models, assess your needs based on these factors:
-
Power Requirements (Wattage): This is the most critical factor.
- Essential Circuits: Do you just need to power the basics (refrigerator, lights, furnace fan, a few outlets)? Add up the running wattage of these essential items, plus the starting wattage of the largest appliance (like a refrigerator or well pump, which requires a surge to start).
- Whole House: Do you want to power most or all of your home’s appliances, including heavy loads like central air conditioning? This requires a much larger unit.
- Tip: Consult an electrician or use online generator sizing calculators to get an accurate estimate. It’s often better to have slightly more capacity than you think you’ll need.
-
Fuel Type:
- Gasoline: Widely available, but short shelf life and requires manual refueling.
- Propane: Longer shelf life than gasoline, cleaner burning, stored in tanks. Good for standby or dual-fuel portable units.
- Natural Gas: Most convenient for standby units if you have a natural gas line, provides unlimited run time during an outage.
- Diesel: More common for very large commercial generators, fuel can gel in cold weather.
- Dual-Fuel: Some portable units can run on either gasoline or propane, offering flexibility.
-
Noise Level: Measured in decibels (dB). Portable generators are often loud (65-85+ dB), comparable to a vacuum cleaner or garbage disposal. Standby generators are generally quieter for their output, and inverter generators (a type of portable) are the quietest option, ideal for residential areas or camping.
-
Portability and Installation: Will you need to move the generator (portable) or do you want a permanent, automatic system (standby)? Standby generators require professional electrical and often plumbing/gas fitting work.
-
Transfer Switch: A transfer switch is essential for safely connecting a generator to your home’s electrical system. It prevents "backfeeding" power onto the utility lines, which is extremely dangerous for utility workers and can damage your generator.
- Manual Transfer Switch: Requires you to manually flip switches to isolate your home from the utility and connect it to the generator.
- Automatic Transfer Switch (ATS): Used with standby generators. Detects power loss, starts the generator, and switches the power source automatically.
-
Budget: Portable generators range from a few hundred dollars to several thousand. Standby generators start at several thousand dollars just for the unit, with installation costs often adding as much or more.
- Features: Look for features like electric start, multiple outlets, GFCI protection, low-oil shutoff, fuel gauges, and hour meters. Inverter generators offer clean power safe for sensitive electronics.

FAQs
-
Q: How do I determine the right size generator for my home?
A: List all the appliances and lights you need to power during an outage. Find their running wattage and the starting (surge) wattage for large motor-driven appliances (like refrigerators, pumps, air conditioners). Add up the running wattage of everything you want to power simultaneously, then add the single highest starting wattage. This gives you an estimate. Consult an electrician for a precise load calculation, especially for standby units. -
Q: What’s the difference between a conventional portable and an inverter portable generator?
A: Conventional portables are simpler, often louder, and produce "raw" AC power suitable for tools and basic appliances. Inverter generators use advanced technology to produce clean, stable AC power (often after converting it from DC), making them safe for sensitive electronics. They are also typically much quieter and more fuel-efficient. -
Q: Is a transfer switch necessary?
A: Yes, absolutely if you plan to connect the generator directly to your home’s wiring (even partially). A transfer switch is a critical safety device that prevents dangerous backfeeding onto the utility grid and isolates your home from the grid during generator use. Using extension cords directly from the generator for individual appliances is an alternative, but limits what you can power and requires careful management. -
Q: Can I run a generator in the rain or snow?
A: Portable generators should never be operated in wet conditions without proper, open-sided shelter. Water and electricity are a dangerous combination. Standby generators are built with weather-resistant enclosures but require clear space around them for ventilation. Always follow the manufacturer’s guidelines and ensure adequate ventilation to prevent carbon monoxide buildup. - Q: How long can a generator run continuously?
A: This varies greatly depending on the fuel source, fuel tank size, and load. Gasoline portables might run for 8-12 hours on a tank. Propane portables’ run time depends on the tank size. Standby generators fueled by natural gas can run indefinitely as long as the gas supply is active. Propane standby units are limited by the size of the propane tank. Always check the manufacturer’s specifications.
