Today, our generators are preferred by 8 out of every 10 homeowners who invest in home backup power. The best models take that in stride while lower-performing generators bog down or even stall. We also look at how efficiently a generator uses fuel and how long it runs on a tank of propane.
Champion 12.5-kW Home Standby Generator, Model 100179
Designed to serve as a backup generator for the most essential appliances, this model includes an automatic transfer switch that can cover up to eight circuits. It supplies up to 7,500 watts of power when using propane but can also operate on natural gas—however power output is limited to 6,000 watts. Unless you opt for a solar-powered generator, you should factor in the cost to run it, which varies by fuel type. Fuel prices vary by region and year, but running a 20kW natural gas generator usually costs around $90 per day, while diesel and propane generators of the same size cost around $200 per day. You won’t find many whole-house gasoline-powered generators, but a portable 5kW gas generator costs around $100 per day to run.

Propane or gasoline powers this workhorse that can keep the lights on, your fridge cold, and your AC purring. Choosing the right generator is more than a simple purchase; it's an investment in comfort and peace of mind. While portable generators offer a quick fix, they often require more setup and deliver less power. On the other hand, a standby generator is like having your own personal power station, ready to light up your entire home at a moment's notice, without any intervention from you.
Where should a whole house generator be installed?
Removing Generac batteries, at $2,000 per 3 kWh battery, will lower the cost. Medical devices such as CPAP machines, respirators, and kidney dialysis machines need electricity to keep functioning. Even non-emergency, health-dependent devices like humidifiers require electricity.
It also offers Wi-Fi capabilities so you can keep tabs on the unit’s operation from anywhere. When evaluating the runtime needed, take into account the fuel consumption and the normal duration of outages in your area. Most portable generators are gasoline-powered and generally can keep lights on and fridges running, but little more, for several hours. They can't be depended on for longer-term backups, such as when you expect power to be out for several days. This depends on the size of the home, the size of the generator, and the number of items that need to be powered.
Generator Cost by Size
It is crucial to select the appropriate generator that meets your requirements and installation needs. A whole house generator is the most powerful type of home generator available. It’s wired to your electric panel and turns on automatically when you lose power, so your entire home stays online if you have the right size. In contrast to a standby or portable generator, a whole house generator will power many more appliances for as long as you can provide it with fuel. They’re more efficient than gas and natural gas generators, but diesel fuel is pricey, which drives up maintenance costs. They also don’t work well in very cold climates since low temperatures can cause the diesel to gel, rendering it useless.
When you’ve determined what power level you need from your whole house generator, you should consider whether you want an air-cooled or liquid-cooled system. An air-cooled generator either passively uses the surrounding air to cool the engine or relies on a fan to maintain temperature. The generator can also be run on a low-speed mode to reduce noise, save fuel and tighten your control. The Briggs & Stratton 12,000 Watt Generator packs quite the punch for a narrow footprint unit and ships at a solid price. Though one of the smallest generators on our best-of list, this product delivers a solid 12,000 watts and comes in as one of the best ranked generators by customer reviews. Prices vary by brand and your specific electrical needs, but generators for 1,500-square-foot homes usually range from $4,000 to $5,500.
The EU2200i is ideal for camping and other outdoor events where generator noise might be frowned on. When we used an oscilloscope to look at the sine wave of the current generated, the curves were smooth and symmetrical, an indicator of “clean” power required by sensitive electronics. When we started and stopped things with bigger motors, like a table saw and air conditioner, the sine wave remained smooth. Running under these heavier loads, we measured the highest sound levels for the EU2200i at 81.2 decibels at the generator. A transfer switch is required when connecting the whole house generator to the main utility line. This switch allows for a smooth transfer from utility power to independent power.
Liquid Propane
To pick the best home generators, we researched popular features, scoured consumer reviews, and talked with product engineers. Many standby generators have automatic transfer switches, meaning they will automatically transfer the power supply in your home from your utility to your generator when the power goes out. Unlike portable generators, home generators are ready the moment your power goes out and most will even start themselves automatically when they sense the draw of power from your home’s electrical panel. Even if they don’t start automatically, home generators often have a remote start, which is significantly easier than a pull-cord that you might find on a portable generator.
A generator engine is similar to your car engine in that it requires upkeep such as oil changes, belt replacements and similar maintenance. Most standby home generators come equipped with several safety features designed to protect them from overheating and failing when you need them most. The larger generators featured on our list are approximately 30 inches by 30 inches by 48 inches, while the smaller generators are closer to 24 inches by 24 inches by 36 inches. The National Fire Protection Association (NFPA) code requires generators to be five feet or more away from openings such as doors and windows.

Of Los Angeles, California on how her Generac home backup generator provides her family with peace of mind. Don't worry about having to be there to start and turn off your Generac home backup generator because it does that automatically--whether you're home or away. Allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet, or PC. They’re built with longevity in mind, but running any type of engine constantly will cause wear and tear on batteries, belts, hoses and fluids.
Another potentially helpful indicator for some homeowners, low oil protection options account for 5% of the total best whole house generators ranking. Be sure to purchase the right type of generator for the fuel you’re looking to use, or check to see if it can be easily converted from one fuel source to the other (most can be). Air-cooled generators are usually less efficient, and they tend to have shorter shelf lives when used in whole-house contexts. Liquid-cooled generators tend to work best, particularly if you live in an area that often reaches temperatures of over 100 degrees, because they are much less likely to overheat.
But we have seen reports of up to 8 hours runtime on propane (the manual specifies 5 hours) with this dual-fuel whole house generator, which also runs on gasoline. Its 10,500 watts should be more than sufficient to run a central air conditioner, as well as a refrigerator, so you can feel more confident about keeping your perishables cold. We also note that the XP1300EH is no slouch— it can easily power a central heating or air conditioner unit. So, although this unit comes with wheels, we consider it more of a standby than a portable unit (although its small footprint seems the right size to take on camping trips). We recommend engaging an electrician to install a transfer switch to your house, as well as the necessary cabling to your house's switchbox. A Kohler home generator costs $2,700 to $16,000 depending on size, ranging from 6 to 48 kW.
The 5500 Dual Fuel is a great option for emergency backup power, but it’s also good for job sites and bigger RVs and campers. To ensure the unit won’t need frequent refueling, it has a large fuel tank that holds nearly 8 gallons—there’s also a fuel gauge designed into the top of the tank. A digital hour meter is included on the front panel to help track maintenance—as it approaches 100 hours and starts to blink, it’s time to change the oil.
