Home Generator Cost

It is essential to be prepared to keep your household running in a power outage at any time. The use of home generators, especially those with high wattage, can make your life easier during blackouts. You can use a home generator to charge your smartphone and prevent food spoiling in the refrigerator. Here’s a comprehensive guide to pricing and home generator costs.

Home Generators Costs

Because there are different sizes of home generators, their prices vary greatly. On the small end of the spectrum, you can buy a generator for $400 that can power your lights and charge your phones and laptops. A house generator should be checked for the number of operating watts to determine how much power it can handle without becoming overloaded. An overloaded generator will fail, so you must determine how much electricity your home’s appliances need before purchasing a generator.

During a power outage, make a list of all the items you would like to be able to use. Also, note how many watts each item uses. Create a separate list of everything you would use simultaneously to determine how many watts you will need. For example, your most significant energy consumption at any given time may be all the bedroom lights, the refrigerator, the hot water tank, and the charging of electronics. If you want to use your heating and cooling system during a power outage, make sure you factor it in.

During a power outage, sewage pumps, sump pumps, refrigerators, and heating systems are essential appliances to have powered. Therefore, you need to make sure the generator you buy can start and operate these appliances. An important consideration to consider when choosing a generator is that certain appliances have higher starting wattages than running wattages. After it has been turned on, a refrigerator may only require 700 watts of power to run, but turning it on in the first place may require 2,100 watts. Therefore, you need a generator with at least 2,100 peak watts to start the refrigerator.

What does the whole home generator cost?

Portable and standby models of whole home generators are available. Unlike portable whole-house generators, standby generators are permanently installed and cannot be moved. The average price for a whole house generator is between $1,000 and $6,000. Prices can be as high as $10,000, but you don’t have to spend much to get an excellent whole-home generator. Then again, if you want the best of the best and have a big budget, you might find that an expensive standby generator meets your needs.

A 5,000-watt generator is typically needed to power a typical home’s essentials. Many portable generators are powerful enough to handle that electrical load, but not all of them. Portable generators usually range from 3,000 to 8,500 watts and cost between $400 and $1,000. More powerful models are also available at higher prices.

It is never a good idea to use a portable generator inside your home, garage, or enclosed space. There is a risk of carbon monoxide poisoning involved. The exhaust from these generators should be vented away from structures, including neighboring houses, at least 20 feet from your home.

A portable inverter generator is also portable but slightly more expensive than a conventional generator. Typically, they cost between $500 and $4,000. A conventional portable generator is more expensive than an inverter generator because it doesn’t run continuously at full power. The power is adjusted as needed. Besides being quieter, inverter generators emit fewer fumes than conventional portable generators. However, it is still necessary to follow the same safety protocols despite the reduced emissions.

You must purchase a canopy for your portable generator, regardless of the type. Additionally, the canopy must be compatible with the generator. This cost should be taken into account when comparing prices. The cost of a generator canopy may range from $100 to $200.

Although you can run some generators alongside one another, it is usually more cost-effective to buy a generator with the power you require. If a model can be parallel-run, determine which specific models can be parallel-run. If a model can be parallel-run, determine which specific models can be parallel-run. Find out if a model can be parallel-run and, if so, with which specific models. The generators that can be parallel run can usually only be safely parallel run with the same model. Inverter generators tend to be compatible with parallel running.

Cost of a home generator by type

There are three basic types of generators you can choose from to provide backup power for your home during outages: Portable, inverter, and standby. In addition to these categories, you can further divide them by fuel type: Gasoline, natural gas, liquid propane, diesel, and solar. Gas and liquid propane generators are typically the most affordable.

Price ranges by fuel type are as follows:

  • Gas: $500-$3,500
  • For natural gas: $1,900-$5,000
  • For liquid propane: $500-$6,000
  • For diesel: $3,000-$15,000
  • For solar: $300-$5,000

Home generator installation cost

Getting a standby generator installed will likely cost you around $1,000. Installation of a whole house generator can cost between $400 and $9,500. Depending on the generator’s size, the existing structures on your property, and where you live, it might be possible. To get a more accurate estimate of the cost of installing a standby generator in your area, you can get price quotes for your area. The installation of a standby generator is not a task you should attempt on your own. A generator installer is needed, as working with gas supplies and electricity can be hazardous and, therefore, unsuitable for a DIY project.

It may be easier to see how costs can add up to $1,000 or more, given all this extra work. You need a transfer switch or an interlock device to use a home generator of either type. Those items need to be installed by a qualified electrician if you do not already have one. Installation costs for a transfer switch range from $500 to $900. A transfer switch establishes a safe connection between the generator and the circuit panel. In the case of a power outage, not having a transfer switch can cause damage to your generator and appliances in your home, not to mention putting utility workers in danger.


The price of a home engine can range between $200 to $20,000, not including installation. In accordance with the home renovation website Fixr.com, a complete household generator typically costs between $10,000 as well as $20,000 to buy and install nationwide. However, anyone can purchase a household generator for as little as $200.
