Buying Guide for the Best Standby Generators

Choosing the right standby generator is crucial to ensure you have a reliable power source during outages. Standby generators are permanently installed and automatically provide power to your home or business when the main power supply fails. To make an informed decision, you need to consider several key specifications that will determine the generator's suitability for your needs. Understanding these specifications will help you select a generator that provides adequate power, operates efficiently, and fits your specific requirements.
Power Output (Wattage)Power output, measured in watts (W), indicates the amount of electricity the generator can produce. This is important because it determines how many and what type of appliances and systems you can run simultaneously during a power outage. Generators are typically categorized into three segments: small (up to 7,500 watts), medium (7,500 to 15,000 watts), and large (over 15,000 watts). To pick the right one, list the essential appliances and their wattage requirements, then choose a generator that can handle the total load with some extra capacity for safety.
Fuel TypeStandby generators can run on various fuel types, including natural gas, propane, diesel, and gasoline. The fuel type is important because it affects the generator's efficiency, cost of operation, and availability of fuel during emergencies. Natural gas and propane are popular for their clean-burning properties and continuous supply through utility lines, while diesel and gasoline are known for their high energy density. Choose a fuel type based on availability in your area, storage capabilities, and personal preference.
Automatic Transfer Switch (ATS)An Automatic Transfer Switch (ATS) is a device that automatically switches the power source from the main supply to the generator during an outage. This is important for convenience and safety, as it ensures a seamless transition without manual intervention. ATS systems come in different sizes and capabilities, so it's essential to choose one that matches your generator's power output and your electrical system's requirements. Consider your need for automatic operation and the complexity of your electrical setup when selecting an ATS.
Noise LevelThe noise level of a generator, measured in decibels (dB), indicates how loud the generator will be during operation. This is important for maintaining a comfortable environment, especially if the generator is located near living or working spaces. Generators can range from very quiet (below 60 dB) to quite loud (above 80 dB). If noise is a concern, look for models with lower decibel ratings or additional noise-reducing features. Consider the placement of the generator and local noise regulations when making your choice.
Run TimeRun time refers to how long a generator can operate on a full tank of fuel or continuous fuel supply. This is important for ensuring that you have power for the duration of an outage without frequent refueling. Run times can vary widely, from a few hours to several days, depending on the generator's fuel efficiency and tank size. Assess your typical power outage duration and choose a generator with a run time that meets your needs, keeping in mind the availability of fuel for extended outages.
Size and InstallationThe physical size and installation requirements of a standby generator are important considerations for ensuring it fits in the designated space and complies with local codes. Generators come in various sizes, and larger units may require more space and specific installation procedures. Evaluate the available space for installation, including clearance requirements, and consult with a professional to ensure proper setup. Consider the ease of maintenance and access to the generator when choosing the size and installation type.
