Quietest Standby Generator For Home


Quiet Standby Generators: Choosing the Right One for Your Needs

One of the biggest drawbacks of standby generators is the noise they produce. While generators are a great backup power source during emergencies, their noise levels can be disruptive to your neighbors and even violate noise ordinances. That’s why many consumers search for “quiet generators” when looking for a standby power source. In this article, we’ll explore the factors you need to consider when choosing a quiet standby generator.


Comparison of Quiet Standby Generators

To help you compare different generator models, we’ve compiled a list of some of the quietest standby generators on the market. These models were selected based on their reported decibel levels during normal operation. Keep in mind that these levels may vary depending on the environment in which the generator operates, and changing the sound levels of each unit.


How Much Power Do You Need?

The first thing to consider when choosing a quiet standby generator is how much power you need. In general, larger generators produce more noise than smaller generators. However, it’s important to balance the noise level with your power needs. You don’t want to buy a generator that’s too small to power your home during an emergency, but you also don’t want to buy a standard generator that’s too large and noisy. To determine your power needs, create an inventory of the appliances and electronics you need to power during an emergency. Consider the power requirements of large appliances like refrigerators, freezers, and air conditioners, as well as smaller appliances like laptops, phones, and lights.

AppliancePower Consumption (Watts)
Refrigerator (16-20 cubic feet)150-250
Freezer (upright or chest, 14 cubic feet)150-250
Clothes Washer350-500
Clothes Dryer1800-5000
Oven (electric)2000-5000
Microwave Oven600-1500
Coffee Maker800-1400
Television (LCD, 40-49 inches)60-100
Desktop Computer50-250
Laptop Computer20-50
LED Light Bulb (60-watt equivalent)9-13

Please note that these values are only meant to serve as general guidelines, and the actual power consumption of an appliance may vary based on factors such as usage patterns, age, and efficiency rating.


What Type of Fuel Do You Want?

The next thing to consider is the type of fuel you want to use. Standby generators can run on natural gas, propane, diesel, or gasoline. Each type of fuel has its own advantages and disadvantages, and the fuel you choose can impact the noise level of the generator. For example, diesel generators are typically noisier than natural gas or propane generators. Before choosing a fuel source, research the noise levels of generators that use that fuel type.

Please note that these sound levels are for typical operating conditions and may vary based on factors such as load, weather, and distance from the generator.


What Type of Generator Do You Want?

The noise level of a generator can be affected by the type chosen. Inverter generators usually operate quietly, while portable and fixed generators tend to produce more noise. Inverter generators are specifically designed to provide clean power, making them a suitable option for powering delicate electronics. Portable generators are great for powering outdoor events or camping trips, but their noise level may not be suitable for residential use. Permanently fixed generators are installed outside your home and are designed to power your entire home during an emergency. While these generators may be noisier than inverter generators, they are much quieter than portable generators.


How Are Noise Levels Measured?

It’s important to understand how noise levels are measured when comparing different generator models. The decibel (dB) scale is logarithmic, which means that a small change in decibel level can represent a large change in perceived noise level. For example, a generator that produces 70 dB of noise is 10 times louder than a generator that produces 60 dB of noise. When comparing generator models, it’s important to look at the manufacturer’s reported decibel level during normal operation. Keep in mind that the distance from the generator and the environment in which it operates can impact the perceived noise level.


Noise Level And Sound Levels

The sound levels listed in the table above indicate the noise level of each generator during typical operating conditions, measured in decibels (dBA). Lower sound levels indicate a quieter generator, while higher sound levels indicate a louder generator. It’s important to note that these sound levels may vary based on factors such as load, weather, and distance from the generator. When choosing a standby generator, it’s important to consider not only the power output and fuel type, but also the noise level and any noise regulations in your area.


Running Wattage

Keep in mind that during a power outage all these fact can change due to load on the unit. Load meaning how much power is required for the home or business. Generator size will also play a role for most traditional generators out there. There are many types of generators from portable power ( a generator for camping ) to a standby generator or dedicated unit to power the house. The DB Ratings will change for each unit.



We can all agree that when we need power, a silent generator is the last thing we worry about. We care more about powering our house and electronic devices in the home to resume life. A backup generator is a wise investment for any home. Any generator for power outages will help with any family to power essential devices and we are all guilty of all the electronic devices we own today. Being prepared for a natural disaster is a wise choice in having reliable power for your family.
