Check out our list of the best whole house generators to see which model would be the best for you to keep your home running even without a connection to the grid. To arrive at the average costs in this article, editorial team members surveyed a range of providers on national and local levels. All averaged figures were correct at the time of publication and may be subject to change. You can often add features to your generator to make it more convenient and efficient. For instance, wireless monitors allow you to monitor your generator’s status remotely, and they cost between $200 and $400, on average.
Home Generators by Energy Output
A whole-house generator, even a smaller one that only powers the medical devices, is crucial in this case. Part of a whole-home generator installation is installing a permanent resting spot. The most common installation method is on a poured concrete pad, which offers reduced vibration and increased airflow and prevents pooling water from damaging or rusting the underside of the unit. Professional installation will run between $50 to $75 per square foot, including site preparation and concrete pouring.
$3,000 – $5,000 average cost to install (labor only)
While the best portable generators work for emergency use during storms or time spent in a camper, a whole-house generator is a different kind of appliance. They are able to support major systems such as electrical and HVAC in the event that the home loses power. Whole home natural gas or liquid propane generators cost $2,000 to $6,000 without installation. Many generators today are dual fuel, meaning they can take either propane or gas. Dual fuel engines are helpful for their versatility — even if you usually use propane, natural gas might be more accessible, especially during a natural disaster. Some standby generators can also be hooked up to your gas line at home, so you don’t have to worry about manually refueling.

It can be a lifesaver in a summer power outage, so it may be worth it for you. Remember that standby generators are usually more expensive than portable generators and require installation. If you're wondering how much it costs to install a whole-house generator, check with the manufacturer before you buy. A standby generator produces electricity to power the systems and appliances in your home during a power outage. Generators are available in various sizes that can power just a few essential home devices or an entire home’s worth of devices and systems.
The 12 Best Home Generators to Keep Your House or Appliances Running
A smaller-output version of the previous generator, the Briggs & Stratton PowerProtect 10kW Standby Generator does exactly what the 12kW version does, just with less output and a more affordable price tag. The Briggs & Stratton 10kW generator is 50% smaller than competitors in the same class, meaning easier installation and the possibility of a more discrete placement around your home. Generac’s technology is designed to keep power consistent to protect more delicate electronics from dangerous distortion. Every week, the self-test mode runs a five-minute low-power test to ensure your generator is ready in case of an emergency. Designed for extreme temperatures, this Champion generator performs reliably at -22°F to 104°F, all while fitting within a standard generator footprint.
The price range for diesel-powered whole house generators is from $2,540 to $17,200. Liquid propane burns cleaner than diesel or gasoline, and it's more dependable than solar power. With no municipal gas lines required, liquid propane—stored in large tanks near the home—allows you to run the whole house generator fully off-grid.
Automatic Transfer Switch
The disadvantages of natural gas are that it’s less energy-efficient than propane and will therefore produce less power and that the generator remains dependent on the gas grid for backup power. Before buying any generator, you should determine the power requirements of your home and your most essential large electric appliances. Refrigerators, air conditioning, sump or well pumps, medical devices, electric water heaters and portable space heaters will likely have the highest power draw and be most essential during power outages. When a power outage occurs, the home generator automatically switches the grid connection off, starts operating and inputs electrical power into the home’s system within a matter of seconds or less.

Powering a whole house up to 3,000 SF typically requires a 13 to 20 kW generator. Use the watt usage chart for generators below to calculate the size required for a house. We’d recommend turning off non-essential devices or even giving the generator a rest right away if you notice it overloading. If you overwork a generator for too long, it may begin to overheat, produce smoke, or cause it to power down. If it stays overloaded for long, you may seriously damage a generator or even start a fire, so consider this an urgent issue.
Inverter Generators
However, this generator can be prone to power surges, so it isn't recommended for sensitive electronics like LCD TVs or laptops. Standard home standbys are capable of powering smaller homes with a kilowatt (kW) range from 9kW to 20kW. Because of its smaller output, this Champion generator features the best average cost and the quietest noise level of all those generators on our list. But keep in mind that per watt, it isn’t performing any better than its competitors—all of which have higher outputs. A transfer switch, connected to your home's power box, automatically changes the power source from the electric utility to your backup. The system is designed to detect when the generator starts so your home can use its energy.
A heavy-duty standby generator with a high power capacity for blackouts. Getting the right switch is just as crucial as getting the right generator, as they work together to restore lost power. To know which will work for you, you'll need to know the amperage of your electrical service panel. You can check this by locating the main breaker in your electrical panel (usually the big pull-out at the top). When choosing the generator output, select a rating that is approximately 20 to 25% higher than the peak load (for example, if the total expected wattage is about 22 kilowatts, choose a 27 kW generator).
The Champion 14-kW aXis Home Standby Generator with 200-Amp Whole House Switch runs about $4,799 on average. The Briggs & Stratton 12,000-Watt Automatic Air Cooled Standby Generator runs about $4,299 on average. The Generac Guardian Wi-Fi Enabled Standby Generator runs about $3,879 on average.

We used an oscilloscope to observe the sine wave of the AC current generated by these machines, and a clamp meter to check voltage output. Some examples of devices we used with large starting and running loads include a large air conditioner and a portable table saw. We evaluated these generators based on ease of starting, power response, sound levels, value, safety, and reliability to select the top performers.
Considering its reliable several-hour runtime, this unit seems a reliable propane-powered solution to the increasingly frequent controlled power outages many communities have adopted to save energy. To ensure continuous electric power during disasters such as hurricanes, however, it may be more sensible to use gasoline instead of propane. With the colder months approaching, we face the possibility of power outages that can last from hours to weeks. Investing in a standby generator is one of the best ways to keep your most important appliances up and running and help everyone inside stay a little more comfortable. Most U.S. homes need at least 5,000 to 7,500 watts to cover minimum needs, so you’ll see standby generators offer nine to 20 kilowatts. Whole house generators will typically start at 22,000 watts and can run as high as almost 50,000.
A whole-house generator is simply a large version of a standby generator, capable of temporarily providing enough electricity to operate everything, or nearly everything, in your home. Inverter generators are similar to traditional portable generators in terms of power output but are much more energy efficient. With these perks comes a higher cost, with models averaging in cost between $1,400 and $4,000. Home standby generators, as detailed above, are permanent installations which automatically turn on during a power outage. Home standby generators run on propane, which is safer to store than traditional gasoline.
