Usually, it will take you a long time to research a favorite product. But rest assured, we are here to assist you with your best backup generator for house issue, no matter what time of day or night.

Before checking the detailed buying guide, you need to first pay attention to some most frequently asked questions about best backup generator for house on famous websites:

  • When you need to find information about a product, where should you refer to it?
  • What should customers keep in mind when deciding whether to invest in a particular product?
  • What is the best-selling model of this product on the market today?
  • What advantages does the product bring to consumers?
  • Is your investment in this product worth it?

Although choosing a product is complicated, it will be more accessible and more available to everyone with today's information technology network. You are now given available sources of information such as famous websites, sale forums, or even customer's feedback. It can be said that information from these sources about best backup generator for house will be beneficial to you.

So now you are expected to focus on needed criteria about best backup generator for house. All of them will come with your investment. 


After you have determined your power requirements, two important factors to consider are its physical footprint and how loud it emits. You will want to have the generator close to your house, no matter how small or large the area.
You should consider how loud the generator will be outside your house. This is measured in decibels. Our generators average between 60 and 70 decibels. A vacuum cleaner, on the other hand, is around 70 to 80 decibels.

Fuel Type

Although home generators can run on a wide variety of fuel types, all those listed here use liquid propane (LP), natural gasoline (NG), or both. The generators that are able to use either one or both of these fuel types can be easily converted without the need for tools.

Stationary Or Portable

Portability is not a top priority if you need backup power for your home. There are many advantages to stationary generators. Stationary generators are generally more quiet, less complicated to start and much stronger than portable ones. They can also be hardwired to your business or home, so don't try this at home! There will not be any messing with extension cords if the power goes out.
You'll need something portable for camping, caravans, boats, fishing, and other home uses. You will need to decide what kind of start-up your portable generator should have. There are both pull-start and batteries start options.

Traditional Or Inverter

These models are ideal for powering delicate electronics such as computers and TVs. These models produce an uninterrupted sine wave of electricity, which ensures there won't be any power surges.
Traditional and standard generators operate at maximum speed, regardless of the power required. An inverter, on the other hand, uses a smart throttle to adjust when you switch on an appliance or light. It saves fuel and runs quieter, more efficiently, and it is healthier for the environment.

Automatic CO Shutoff

If a CO sensor is installed, this critical safety feature will automatically turn off a generator's motor. To be included on the CR list, a portable generator should have this safety feature. This technology is available in more brands than ever before, even heavyweights like Ryobi, Honda and Generac. We have more than a dozen generators with CO safety shutoffs.


Single-phase generators generate single-phase power that is comparable to the one used in most household appliances. Single-phase generators can be used in small and large homes.
Three-phase power is often required for larger commercial operations. Therefore, a generator with three phases is necessary.
Although three-phase generators are able to be operated as one phase, the power output of a single phase will not be as high as when it is run in three phases.

Alternative Fuel Capacity

Although most portable models are powered by gasoline, some have the ability to be run on natural gas or propane. Others can also be modified with kit conversions.

Power Requirements

You should first determine your power needs before purchasing a generator. Air conditioning, refrigerators, sump pumps or well pumps and medical devices will all have high power draws and are most important during an outage.


How Big Of A Generator Do I Need To Run A House?

A home requires a minimum of 5,500 to 7,500 watts in order to operate. Common home generator capacities start at 10,000 watts.

Can I Use A Portable Generator For Backup During A Power Outage?

Yes. Yes. You can connect household devices and appliances to a portable generator, but not all at once.
You should never plug the generator in to an electrical outlet at home or work. A certified electrician will install a manual power transfer switch that conforms to electrical codes if you want to attach a portable generator into your home or business's wiring.

How Far Away From The House Does A Generator Need To Be?

National Fire Protection Association guidelines allow small generators to remain at least 18 inches away from exterior walls. However, local codes may require you to check for more strict requirements. Installers who are professionals should be familiar with the codes to help plan where your generator will go.

How Long Can You Run A Whole House On A Generator?

The home generator could theoretically last indefinitely if it has unlimited fuel supply and is free from mechanical problems. The generator engine works in the same way as a car engine. It requires regular maintenance such as an oil change, replacement of belts and other similar tasks.

What Is The Best Generator To Buy For Home Use?

There are many factors that go into choosing the best generator for your home. These include your power needs, your essential appliances, such as fridges, air conditioners and sump pumps.

Does The Portable Generator Need To Be Grounded?

Yes. Yes. You risk electrocution if the generator isn’t properly grounded. Follow all federal, state and local rules relating to grounding.

Are Home Generators Worth It?

Although they can be more expensive than portable generators, home generators will provide you with peace of mind and ensure that your family is safe during an outage.

Can I Vent The Exhaust Out Of An Enclosed Area?

No. No. Generators that are portable can be used outdoors where ventilation is available. Like all gasoline engines' exhaust, generator exhaust contains toxic carbon monoxide. You can find more details in the Portable Generator Safety Tips.

How Often Should I Perform Routine Maintenance?

For the maintenance recommendations, consult your owner's guide.
