Power outages are an inevitable fact of life, and having a reliable backup generator can make all the difference when they occur. However, choosing the right genset or backup generator can be a daunting task, with several options available.

In this comprehensive buyer’s guide, we’ll walk you through the key factors to consider when choosing the perfect backup generator for your needs.

Determine Your Power Requirements

The first step in choosing a genset is to determine your power requirements. Make a list of the essential appliances and systems you want to keep running during an outage. This might include lights, refrigeration, heating and cooling systems, and medical equipment. Calculate the wattage needed for these devices and add a buffer for any additional items you may want to power. This total will guide your choice of generator size.

Fuel Type

Backup generators come in various fuel types, each with its pros and cons. The common options are:

Gasoline: Portable generators often run on gasoline, which is readily available but less efficient and has a shorter shelf life.

Propane: Propane generators offer cleaner burning fuel and can be stored for long periods.

Diesel: Diesel generators are highly fuel-efficient and durable, making them suitable for larger or industrial applications.

Natural Gas: If you have access to a natural gas line, a natural gas generator can provide a continuous supply of power.

Consider the fuel availability in your area, as well as factors like cost, maintenance, and environmental impact when choosing a fuel type.

Generator Type

Generators are available in two main types:

Portable Generators: These units are smaller and can be moved to different locations. They are ideal for providing power to specific appliances or tools during an outage.

Standby Generators: Standby generators are permanently installed and are designed to provide continuous power during extended outages. They are typically more powerful and automatically activate when the main power supply fails.

The choice between portable and standby generators depends on your specific needs and budget.

Noise Level

Generators can be noisy, and the noise level is an important consideration, especially if you live in a densely populated area. Look for generators with noise reduction features and consider the unit’s decibel rating. Quieter generators are more comfortable to live with during extended power outages.

Size and Placement

The size of your genset is determined by your power requirements. Portable generators are typically smaller and easier to store, while standby generators may require more space and proper installation. Ensure you have a suitable location and proper ventilation for the generator.

Transfer Switch

For standby generators, a transfer switch is a critical component. It automatically switches your home’s power source from the grid to the generator when the main power fails, and vice versa when the power is restored. A transfer switch is essential for ensuring a safe and seamless transition to backup power.

Maintenance and Warranty

Regular maintenance is necessary to keep your generator in optimal working condition. Consider the ease of maintenance and the availability of service in your area when making a choice. Also, check the manufacturer’s warranty to ensure you have proper coverage in case of any issues.


Backup generators come in a wide range of prices, depending on their size, type, and features. Set a budget before you start shopping, and consider not only the upfront cost but also ongoing expenses, including fuel, maintenance, and any necessary installation.

Compliance and Local Regulations

Local regulations, building codes, and emissions standards may influence your choice of generator. Ensure that your selected generator complies with all relevant laws and regulations in your area.
