Let’s take a look at the facts. Standby generators are permanently installed generators that automatically switch on when your power goes out. You do not need to be home in order to turn on a standby generator. A transfer switch automatically monitors your home’s power and will transfer your home’s electrical load to your standby generator if the power goes out.

A standby generator is installed outside of your home, much like a central air conditioning unit, and effortlessly runs on your home’s natural gas line.

Portable generators use a gas-powered engine to power your home. This engine works by turning an alternator to generate electrical power. Each portable generator has power outlets allowing you to plug in extension cords, electric-powered tools, or appliances into it.

In general, the more powerful the generator, the more outlet combinations available and the more appliances you can run at a time. Because portable generators are powered by a gas engine, they should always remain in a well-ventilated outdoor space for safety reasons.

Standby generators make highly effective upsells and with our aging power grid, are often sought out as “must have” features of new home builds.

Made installation of our generator extremely easy. Took care of all permitting with the town and made the process very simple. After a major power outage, they sent their service team in a snowstorm to service the generator and ensure it would keep us going throughout the snowstorm.

Excellent service. Very pleased with this company. Cannondale has been maintaining our 20KW Generac Guardian Series generator (first installed in 2012) for 2 years now. During the recent power outage, the generator ran flawlessly for 130 hours straight.

We added 16 ounces of motor oil after the first 75 hours of run time, as would be expected during a period of extended usage.

The professionals at Cannondale were reachable, and provided helpful advice on lubricant selection, among other things. If you own a generator and live in Westchester or Fairfield counties, you must become a Cannondale client.

They are the absolute best! Charged me a fraction of a competitors quote and was very pleasant throughout. Predicting exactly when a prolonged power outage might occur is like predicting the precise time and location of a single lightning strike.

While it might one day be possible with advancements in technology, we’re currently in a place where the best we can do is to prepare for the possibility of being without power for extended periods.

Whether it’s the result of a significant weather event or just a random screw-up by your local utility company, a prolonged power outage is a hassle. Groceries can spoil, your house can heat up (or cool down) uncomfortably, and you definitely won’t be able to watch any of your favorite shows on Netflix.

But if you invest in a standby generator, also known as a whole house generator, you can keep all systems running if the power does go out. In this article, we’ll detail the features of the Top 10 Standby Generators of 2021 and we will also present the most important things to consider when purchasing a whole house generator in our Buyer’s Guide.

This 50-amp generator from Champion comes with an automatic transfer switch that makes the transition from the grid to the generator seamless when the power goes out.

It operates efficiently in extreme temperatures (-22 to 104 degrees Fahrenheit) and comes with an all-weather, composite pad for easy mounting and installation next to your home.

  • It’s certainly a residential-friendly generator that will also provide reliable power in extreme weather conditions.
  • It is rated to operate efficiently in temperatures ranging from -22 to 104 degrees Fahrenheit.
  • The Champion 8.5-kW home standby generator features an automatic transfer switch with eight available circuits.
  • When an outage occurs, it will provide a seamless transition from utility power to generator power with a 24-volt starting system that requires no warming kit and regularly performs weekly self-diagnostic tests.
  • Finally, this generator provides up to 8500 watts of continuous power when running on propane (7500 watts when running on natural gas) and doesn’t require refueling, manual operation, or the use of extension cords.

It also includes a load center automatic transfer switch to safely switch your house from utility power to generator power when an outage occurs. This generator is protected by a corrosion-resistant enclosure and backed by a five-year, 2,000-hour warranty.

In this Buyer’s Guide, we’ll discuss the most important characteristics of a whole house generator and provide guidance for you to make the best decision possible. We will focus on fuel source, power needs, transfer switches, cooling mechanisms, installation location, and safety tips.

Most standby generators that deliver up to 22-kilowatts will be powered by natural gas or liquid propane (LP). Generators that run on diesel tend to cost a lot more and they must be liquid-cooled (more on that later on!).

Generators that run on LP or diesel fuel will require a tank large enough to hold ample gas to properly operate the generator. Similarly, a generator that runs on natural gas will need to be compatible with your home’s existing natural gas meter and gas lines.

This information should be available in the installation manual for the generator of your choice, but it’s a wise step to double-check compatibility with your contractor and/or architect. Picking the right size standby generator is important because the goal should be to keep everything in your house functioning as close to normal as possible when an outage occurs.

But if that’s not your goal, you still want to make sure your generator provides enough power to back up crucial systems like refrigerators and AC/heating units. If you want a generator that can power your air conditioner during a blackout, you’ll first need to know the size of your AC unit.

The unit’s data plate should be an easy enough location to identify its size, which will typically be displayed in BTUs or tons. One ton is equal to 12,000 BTUs and 3.517 kilowatts of energy.

So, if you have a three-ton air conditioner, you’ll need a generator that can provide at least11-kilowatts (11,000 watts) of energy.

  • A 5-ton AC unit will require a 20-kilowatt (or larger) standby generator.
  • You can calculate the perfect-sized generator for your home’s needs here (5).
  • Once a generator and its accompanying transfer switch are hooked up to your home’s electrical panel, it will automatically be sensing utility power.
  • When it detects an outage, the switch starts the engine on your generator and, simultaneously, disconnects your home from the power coming through the utility line.
  • Choosing the right transfer switch is just as important (if not more so) than choosing the right-sized generator.
  • The transfer switch must be able to handle a load of your home’s main breaker while working in tandem with your generator.
  • To select the right transfer switch, you need to find out the amperage of your home’s electrical service panel.
In most homes, you’ll be able to find this on the panel of your home’s main breaker, but you can also ask your home’s installer to verify the correct number for you.
Many homes have 200-amp main breakers, but many older and smaller homes may have 100 or 150 amp breakers. The transfer switch you choose should be rated for the same amperage as your home’s main breaker.

While it depends on the exact model, of course, most air-cooled generators are capable of powering 8, 10, 12, or even 16 key circuits in your home’s main distribution panel when the power goes out. For the vast majority of homes, air-cooled generators provide exceptional reliability and fantastic value. Liquid-cooled generators, however, also have their applications.

These generators use an enclosed radiator system to keep the engine cool. This radiator system is similar to what you’d find in most modern automobiles. As you might imagine, larger generators that deliver more kilowatts of energy also require larger engines that can maintain higher power output.

For this reason, these generators need to be cooled more aggressively and they require a liquid-cooling system to do so. How close or far you can install your generator to your home will depend on a few factors.

The generator’s safety rating and installation recommendations are good starting guides. But you should also be sure to check in on any local restrictions or regulations governing safe generator installation.

  • Ultimately, your decision on where to install your generator should adhere to local regulations and the manufacturer’s explicit instructions.
  • That being said, there are several other things to consider when deciding where to install your home’s standby generator.
  • First, you’ll want to locate the generator as close to your home’s existing fuel supply and electric panel as possible.
  • This will mean less wire, less gas pipe, less installation cost, and, overall, less time to get the unit installed.
  • Second, you’ll want to choose a spot that offers consistent, unobstructed airflow.
  • This will help keep the generator cool and leaving plenty of room around the generator will also make any future service work needed that much easier.
  • Third, make sure your generator isn’t located close to windows, doors, AC condensers, or vents.
The National Fire Protection Association (NFPA) (6) actually requires that generators are installed at least five feet away from the nearest wall unless that particular wall has a fire resistance rating of one hour or more.
As anyone that has ever felt even a minor electrical shock knows, electricity is nothing to be taken lightly. When you’re installing and operating a standby whole house generator, there are several safety precautions to take into consideration.

As a general rule of thumb, generators should never be run in a basement or any other enclosed area. The fumes they produce can be lethal to anyone who is sleeping or otherwise unaware of the danger. Your generator’s fuel should also be stored far away from the generator itself and you should never begin to refuel your generator while it is hot or while the engine is running.

We hope that, by now, you have a good idea of what to consider when purchasing a standby generator. But we understand that there is a lot to cover so, in the interest of providing the most comprehensive buyer’s guide possible, we’ve put together this list of frequently asked questions to address a few more potential concerns.

While it’s certainly possible, it wouldn’t be the most economical option with the current prices of natural gas, liquid propane, and diesel fuel. The cost of fuel to continuously power your generator would currently far exceed the cost of buying power from the utility company.

In addition, all responsibilities for maintenance of your home’s power source would then fall on you as the individual, rather than your municipal utility company.

Having an enclosure over your generator is highly recommended. These enclosures protect your generator from rust and corrosion.

Many manufacturers recommend aluminum or composite enclosures because they are more resistant to rust and corrosion than other materials, such as steel.

  • The number of hours your generator can run on a single propane tank will depend on the size of the tank, the size of the generator, and the appliance load that the generator is being asked to power.
  • For the purposes of providing you with some numbers to wrap your head around, however, here is what you might expect from an average 16-kilowatt generator operating at 50% load capacity:.
  • 100-gallon propane tank: 50 hours.
  • 250-gallon propane tank: 125 hours.
  • 500-gallon propane tank: 251 hours.
  • 1,000-gallon propane tank: 503 hours.
  • Every generator requires regular maintenance.
  • This can be as simple as periodic oil and filter changes, but larger services are sometimes necessary as well.
Preventative maintenance is always a good idea and it will help you ensure that your generator performs to the best of its ability for years.
You should always consult the owner’s manual for your specific generator for the best information on routine maintenance procedures and schedules. As our population continues to grow, our demands for electricity are also increasing.
