Quietest Standby Generator For Home


Quiet Standby Generators: Choosing the Right One for Your Needs

One of the most significant 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. Many consumers search for “quiet generators” for a standby power source. This article will explore the factors you must 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 regular operation. Remember that these levels may vary depending on the generator’s environment and each unit’s changing sound levels.

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, balancing the noise level with your power needs is essential. 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, inventory 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 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 generator’s noise level. For example, diesel generators are typically noisier than natural gas or propane generators. Before selecting 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 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 designed to provide clean power, making them suitable for powering delicate electronics. Portable generators are great for powering outdoor events or camping trips, but their noise level may not be ideal 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?

Understanding how noise levels are measured when comparing different generator models is essential. The decibel (dB) scale is logarithmic, which means that a slight change in decibel level can represent a significant change in perceived noise level. For example, a generator that produces 70 dB of noise is ten times louder than a generator that produces 60 dB of noise. When comparing generator models, looking at the manufacturer’s reported decibel level during regular operation is essential. Remember 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 load, weather, and distance from the generator. When choosing a standby generator, it’s essential to consider the power output and fuel type, the noise level, and any noise regulations in your area.

Running Wattage

Remember that during a power outage, all these facts can change due to the load on the unit. Load means 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 a silent generator is the last thing we worry about when we need power. 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 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.
