Power Generators: Essential Guide to Home Backup Solutions

What is a home backup power generator?

A home backup power generator is a device designed to provide electricity to your house during power outages. These systems can be essential for maintaining comfort, safety, and functionality when the main power grid fails. Home backup generators typically run on natural gas, propane, or diesel fuel, and can power critical appliances and systems such as refrigerators, heating and cooling systems, and medical equipment.

How much does a whole house generator cost?

The cost of a whole house generator can vary significantly based on several factors, including the size of your home, power requirements, and the type of fuel used. On average, homeowners can expect to pay between $7,000 to $15,000 for a complete system, including installation. However, more powerful units for larger homes can cost upwards of $20,000 or more.


Generator Size Average Cost Range (Including Installation)
7-10 kW $4,000 - $9,000
12-20 kW $10,000 - $15,000
22-45 kW $15,000 - $30,000+

Prices, rates, or cost estimates mentioned in this article are based on the latest available information but may change over time. Independent research is advised before making financial decisions.


It’s important to note that while the initial cost may seem high, many homeowners find the investment worthwhile for the peace of mind and protection it provides during power outages.

What types of generators are suitable for emergency home use?

When considering a generator for emergency home use, there are several options available:

  1. Standby Generators: These are permanent installations that automatically turn on when the power goes out. They’re ideal for whole-house backup but are the most expensive option.

  2. Portable Generators: Less expensive and more versatile, portable generators can be moved and stored when not in use. They’re suitable for powering essential appliances but require manual setup and refueling.

  3. Inverter Generators: These are more fuel-efficient and quieter than traditional portable generators, making them a good choice for residential areas with noise restrictions.

  4. Solar Generators: While less powerful, solar generators are eco-friendly and can be a good supplement to other backup power sources, especially in sunny climates.

The choice depends on your specific needs, budget, and local regulations.

What should I consider when choosing a standby generator for home?

Selecting the right standby generator for your home involves several considerations:

  1. Power Output: Determine how much power you need by calculating the wattage of essential appliances and systems you want to run during an outage.

  2. Fuel Type: Choose between natural gas, propane, or diesel based on availability and your preferences. Natural gas is often the most convenient if you have a gas line.

  3. Installation Requirements: Consider the space needed for the generator and transfer switch, as well as local zoning laws and permit requirements.

  4. Noise Levels: Look for generators with lower decibel ratings, especially if you live in a densely populated area.

  5. Brand Reputation and Warranty: Research reliable brands and compare warranty offerings to ensure long-term support.

  6. Maintenance Needs: Consider the ongoing maintenance requirements and associated costs.

What does a generator installation service typically include?

A professional generator installation service usually comprises several key steps:

  1. Site Assessment: Evaluating your home’s electrical needs and determining the best location for the generator.

  2. Permitting: Obtaining necessary permits from local authorities.

  3. Fuel Line Installation: Setting up the connection to your home’s natural gas line or installing a propane tank if needed.

  4. Electrical Work: Installing the transfer switch and connecting the generator to your home’s electrical panel.

  5. Generator Placement: Properly positioning and securing the generator on a concrete pad or other suitable foundation.

  6. System Testing: Ensuring the generator functions correctly and switches on automatically during a power outage.

  7. User Training: Providing instructions on how to operate and maintain the generator system.


Service Component Typical Cost Range
Site Assessment $200 - $500
Permitting $50 - $200
Electrical Work $500 - $1,500
Concrete Pad $300 - $800
Labor $2,000 - $4,000

It’s crucial to hire a licensed and experienced professional for generator installation to ensure safety and compliance with local codes.

Power generators provide an essential safeguard against unexpected power outages, offering homeowners peace of mind and continued access to electricity during emergencies. While the initial investment can be significant, many find the long-term benefits of a reliable backup power system to be invaluable. By carefully considering your power needs, budget, and local regulations, you can select and install a generator that best suits your home and lifestyle.
