Key Differences Between Standby and Backup Generators

Power outages can happen at any time, leaving your home without electricity for hours or even days. Whether due to severe weather, utility failures, or unexpected grid issues, losing power can disrupt your daily life and put essential systems—like heating, cooling, and refrigeration—at risk. That’s why many homeowners invest in a generator to keep their home running during an outage.

But with so many options available, how do you know which type of generator is right for your home? Two of the most common choices are standby generators and backup generators. While these terms are sometimes used interchangeably, they are not the same. Understanding the differences between them can help you make the best decision for your home’s power needs.

In this guide, we’ll break down the key differences between standby and backup generators, including how they function, their benefits, and which one might be the best fit for your home. Whether you’re looking for a solution that powers just the essentials or a generator that keeps your entire home running without interruption, we’ll help you determine the right choice.

An Overview of Standby Generators

Standby generators offer automatic operation, seamless transition to backup power, and the capacity to run your entire house. Here’s a closer look at what sets them apart from backup generators:

Automatic Generator Operation

Standby generators are designed to kick in automatically when your main power source (usually the electricity from your utility company) fails. They are always on standby, ready to provide power as soon as an outage is detected. This means you don’t have to be home or manually start the generator in case of a power outage.

Permanent Generator Installation

Standby generators are typically permanently installed on a concrete pad or a stable surface near your home. They are connected to your home’s electrical system, including the main electrical panel. This setup requires professional installation.

Fuel Sources

Standby generators usually run on natural gas or propane, which are directly piped to your home, so you don’t have to worry about refueling them during an outage.

Standby Generator Power Capacity

Standby generators come in various sizes and can provide enough power to run your entire house, including appliances, heating/cooling systems, and lights.

Cost of Standby Generators

Standby generators are more expensive than backup generators due to their automatic operation, installation complexity, and higher power capacity. Costs can vary based on your specific needs and the size of the generator you get.

What Are Backup Generators?

If you’re looking for a more budget-friendly way to keep essential appliances running during power outages, backup generators, also known as portable generators, are worth considering. Unlike standby generators, they require manual operation and offer portability, making them ideal for temporary use. Here are their key features and how they differ from standby generators:

Manual Operation

Backup generators do not start automatically. You need to set them up, start them, and connect them to your essential appliances or circuits during a power outage. This requires your presence and manual intervention.

Portable and Temporary

Backup generators are smaller and portable, making them suitable for temporary use during outages. They can be moved around and stored when not in use.

Fuel Sources for Backup Generators

Backup generators often run on gasoline, propane, or diesel fuel. You need to keep a supply of the chosen fuel on hand and refuel the generator as needed.

Backup Generators Power Capacity

Backup generators come in various sizes, but they usually provide enough power to run critical appliances, such as refrigerators, heaters, or a few lights. You’ll need to choose the size that meets your specific needs.

How Much do Backup Generators Cost

Backup generators are more affordable than standby generators because they don’t require permanent installation, automatic operation, or extensive electrical connections. However, their cost can vary based on their size and features.

Best Brands for Home Generators

When it comes to choosing a reliable home generator, selecting the right brand is just as important as choosing the right type of system. Two of the most trusted names in the industry are Generac and Kohler—both known for manufacturing high-quality standby and backup generators that homeowners can depend on when the power goes out. Each brand offers unique advantages, whether you need a standby generator for whole-home coverage or a backup generator for powering essential appliances.

Generac Generators: Industry Leader in Home Backup Power

Generac is one of the most well-known names in home generators, providing dependable solutions for homeowners who want peace of mind during power outages. Generac generators come in both standby generators and backup generators, with options tailored to different home sizes and power needs.

Why Choose a Generac Residential Generator?

Generac generators are designed for automatic operation, meaning they detect power loss and turn on within seconds—ensuring minimal disruption. They also feature Quiet-Test™ technology, which allows them to run self-diagnostic tests at a lower RPM for quieter performance. Generac’s air-cooled standby generators are particularly popular, offering a balance of affordability and reliability.

Kohler Generators: Trusted Performance and Durability

Kohler has been manufacturing reliable power solutions for over a century, earning a reputation for exceptional durability and high-performance generators. Homeowners looking for a robust, long-lasting system often turn to Kohler generators for both standby generators and backup generators that can handle extended power outages.

Features of Kohler Generators

One of the standout features of Kohler’s home standby generators is their rapid response time. Within 10 seconds of a power outage, a Kohler standby generator activates, restoring power quickly and efficiently. These generators also provide clean, stable power, which is essential for protecting sensitive electronics like computers and home entertainment systems.

Kohler’s Corrosion-Proof Enclosures ensure that their generators can withstand extreme weather conditions, making them an excellent choice for homeowners in areas prone to storms and harsh climates. Their powerful commercial-grade engines are designed for long-term durability, meaning they can handle heavy loads and extended run times without performance issues.

Which Type of Generator Is Best for Your Home?

If you want seamless, automatic power during outages and have a higher budget, a standby generator is a great choice. If you prefer a more affordable option and are willing to manually set up and operate the generator during outages, a backup generator is a good choice.

When trying to figure out which type of generator is best for your home, consider the power requirements of your essential appliances and decide whether you need whole-house coverage or just a few critical circuits.

Ultimately, your decision should be based on your lifestyle, the level of convenience you desire, and your budget. It’s also a good idea to consult with a professional electrician or generator expert to help you make the right choice for your specific situation.

In the end, whether you choose a standby or backup generator, the goal is the same: keeping your lights on when the world goes dark. It’s your power choice!
