Power outages can strike at any time, turning everyday activities into challenging tasks. This is where a reliable generator steps in. A generator provides a temporary solution during power failures, making it an indispensable tool for homes and businesses. 

However, purchasing a generator isn’t as simple as picking one off the shelf. The array of options available can be overwhelming, and understanding which generator best fits your needs requires careful consideration.

This comprehensive guide will outline some crucial factors to consider when buying a generator, from assessing your power needs and understanding the different types of generators, to considerations on fuel type, size, noise level, safety features, and more. Read on to glean some expert advice and make your generator shopping experience a breeze.

Understanding Your Power Needs

The very first step in selecting a generator is to understand your power needs. This is primarily determined by the wattage required to power your devices and appliances during an outage. Some people only want to power essential systems such as lighting, refrigeration, and heating. Others, especially businesses, might need to maintain operations as usual, meaning they’ll need a more powerful generator.

To determine the required wattage, you should make a list of all the devices and appliances you’ll need to power during an outage. Once you have this list, find out the starting and running wattage for each item. The starting wattage is the initial power surge required to start an appliance, while the running wattage is the power needed to keep it running. The generator you choose should be capable of handling the total starting and running wattage.

To facilitate the calculation process, many manufacturers and dealers, including those offering generators for sale Connecticut, provide online wattage calculators. These tools are designed to help customers estimate their power needs accurately.

Choosing The Right Type Of Generator

Generators come in various types, each with its own set of benefits and drawbacks. The most common types include portable generators, inverter generators, and standby generators. 

Portable generators are compact and relatively inexpensive, making them suitable for temporary power needs or for outdoor events. They can be manually started and connected to your devices using extension cords.

Inverter generators, on the other hand, are quieter and more fuel-efficient than standard portable generators. They produce cleaner power, which makes them safer for sensitive electronics like computers. However, they tend to have a lower power output and are typically more expensive.

Standby generators are permanent installations that can automatically provide power during an outage. They have larger fuel tanks, meaning they can run for longer periods without refuelling. They’re ideal for homes and businesses that need a reliable, long-term solution for power outages. However, they require professional installation and tend to be more costly than portable or inverter generators.

Assessing Fuel Type And Efficiency

Generators can run on various types of fuel, including gasoline, diesel, propane, and natural gas. Each fuel type has its pros and cons. 

Gasoline, for example, is widely available and usually inexpensive, but it has a shorter shelf life and is less efficient than other fuels. Diesel generators are known for their longevity and fuel efficiency but can be noisier and require more maintenance.

Propane is clean-burning and has a virtually unlimited shelf life, making it an excellent choice for infrequently used generators. Natural gas generators are environmentally friendly and can be connected to your home’s natural gas supply, eliminating the need for refuelling. However, they might not be as powerful as diesel or gasoline generators.

Fuel efficiency is another essential factor to consider. More fuel-efficient generators can run longer on the same amount of fuel, saving you money and reducing environmental impact.

Considering Size And Portability

The size of the generator you choose will be influenced by your power needs and the available space at your home or business. 

Large, permanent standby generators are ideal for homes and businesses with high power needs and enough outdoor space for installation. Smaller, portable generators are more suitable for temporary power needs or locations with limited space.

Portability is another crucial factor, especially for those who plan to use the generator for various purposes, such as camping, tailgating, or powering tools at a worksite. Look for models with sturdy wheels and handles if you plan to move your generator frequently.

Evaluating Noise Level

All generators produce noise, but the level can vary significantly between different models and types. In residential areas, high noise levels can be disturbing and may even violate local noise regulations. For businesses, noisy generators can create an unpleasant environment for employees and customers.

Most generators provide a decibel (dB) rating, which measures their noise level. Standby generators and inverter generators are typically quieter than standard portable generators. Some models also feature mufflers or sound-dampening enclosures to reduce noise.

If noise is a significant concern, consider investing in a generator with a low dB rating. However, remember that there’s usually a trade-off between power and noise: more powerful generators tend to be noisier.

Considering The Features

Modern generators come with a range of features designed to enhance their safety, convenience, and performance. Automatic start, for example, is a feature that allows standby generators to start up on their own when a power outage is detected. This ensures that your power needs are met without any action required on your part.

Another desirable feature is multiple power outlets, which allow you to connect several devices at once. Look for models with different types of outlets (e.g., 120V, 240V, USB), especially if you plan to power a variety of appliances and devices.

Additional features to look for include fuel gauges, low-oil shutdown (to protect the engine from damage), and an hour meter (to help with maintenance schedules). Some models also offer remote monitoring capabilities, enabling you to control and monitor your generator from your smartphone.

Understanding Warranty And Support

A warranty is a crucial consideration when purchasing a generator. It serves as a guarantee from the manufacturer that they stand behind their product. Look for generators that come with a substantial warranty period, and be sure to understand what’s covered under the warranty.

Additionally, consider the kind of support available. Does the manufacturer offer customer service and technical support? Can you easily find parts for maintenance or repair? These considerations can make a difference in your experience down the line.

Also, when looking at generators for sale Connecticut, consider the reputation of the dealer. Do they offer installation and maintenance services? Are they authorized by the manufacturer? The dealer’s expertise and services can be just as important as the generator itself.

Safety Features And Regulations

Generators can pose various safety risks if not used or installed correctly. Therefore, it’s important to choose a generator equipped with safety features that protect both you and the generator. 

For instance, a low-oil shutdown feature protects the generator’s engine from damage if the oil level becomes too low. Similarly, an overload protection feature ensures that the generator doesn’t get damaged due to excess power demand.

Moreover, many areas have regulations regarding generator use, including noise level limits, installation codes, and emissions standards. When browsing through generators, ensure the chosen model complies with these local generator standards. The knowledgeable staff at your dealer should be able to guide you on this.

Ensuring Maintenance

Like any machine, a generator requires regular maintenance to ensure optimal performance and a long lifespan. Before making a purchase, consider the maintenance requirements of the generator. Does it require frequent oil changes? Are the parts easy to access for cleaning and servicing?

Also, look for durable, high-quality components that are built to last. The longevity of a generator is often a reflection of its build quality. A high-quality, well-maintained generator can last for many years, making it a worthwhile investment.

Considering Environmental Impact

The environmental impact of a generator is another key consideration. Generally, generators that run on cleaner fuels like natural gas or propane have lower emissions compared to those running on gasoline or diesel. 

Furthermore, modern generators often come with features that reduce their environmental impact. For instance, eco-mode or smart throttle features adjust the engine speed to match the load, resulting in lower fuel consumption and reduced emissions.

As the demand for eco-friendly power solutions grows, more and more generators for sale in Connecticut are embracing these environmentally conscious features. Choosing a greener generator not only reduces your carbon footprint but can also lead to cost savings over the generator’s lifetime.


Selecting the right generator is not a decision to be taken lightly. By considering your power needs, the type of generator, fuel type, size, noise level, features, and warranty, you can ensure that you choose a generator that meets your specific requirements.
