Buying Guide for the Best Emergency Home Generators
Choosing the right emergency home generator is crucial to ensure that your home remains powered during outages. The right generator can keep your essential appliances running, provide comfort, and ensure safety. When selecting a generator, consider the power output, fuel type, runtime, and other features that match your specific needs. Understanding these key specifications will help you make an informed decision and find the best fit for your home.Power Output (Wattage)Power output, measured in watts, indicates how much electricity the generator can produce. This is important because it determines how many and what type of appliances you can run simultaneously. Generators typically range from 1,000 watts to over 10,000 watts. For small essentials like lights and a refrigerator, a generator with 3,000-5,000 watts may suffice. For larger homes or to power more appliances, consider a generator with 7,000-10,000 watts or more. Assess your power needs by listing the appliances you want to run and their wattage requirements.
Fuel TypeGenerators can run on various fuels, including gasoline, propane, natural gas, and diesel. The fuel type affects the generator's runtime, availability of fuel, and maintenance. Gasoline is widely available but has a shorter shelf life. Propane and natural gas are cleaner and have longer shelf lives, but may require additional installation for natural gas. Diesel is efficient and has a long shelf life but can be more expensive. Choose a fuel type based on availability, storage, and your preference for maintenance and environmental impact.
RuntimeRuntime refers to how long a generator can operate on a full tank of fuel. This is important for ensuring continuous power during extended outages. Generators with larger fuel tanks generally have longer runtimes. For example, a generator with a 5-gallon tank might run for 8-10 hours at half load. Consider how long you need the generator to run without refueling. If you expect long outages, look for a generator with a longer runtime or the ability to connect to a larger external fuel source.
PortabilityPortability refers to how easy it is to move the generator. This is important if you need to transport the generator to different locations or store it when not in use. Portable generators typically have wheels and handles for easier movement. If you plan to use the generator in multiple locations or need to store it away when not in use, consider a portable model. For permanent installations, a standby generator that is fixed in place may be more suitable.
Noise LevelNoise level, measured in decibels (dB), indicates how loud the generator is during operation. This is important for comfort and compliance with local noise regulations. Generators can range from 50 dB (quieter) to over 80 dB (louder). If you live in a neighborhood with noise restrictions or prefer a quieter environment, look for generators with lower noise levels. Inverter generators are typically quieter than conventional models and may be a good choice for noise-sensitive areas.
Start TypeStart type refers to how the generator is started. Common options include manual recoil start, electric start, and remote start. This is important for ease of use, especially during emergencies. Manual recoil start requires pulling a cord, which can be physically demanding. Electric start uses a push-button or key, making it easier to start. Remote start allows you to start the generator from a distance. Choose a start type based on your preference for convenience and physical ability.
Safety FeaturesSafety features include automatic shutoff, overload protection, and low-oil shutoff. These are important for protecting the generator and ensuring safe operation. Automatic shutoff turns the generator off if it detects dangerous conditions, such as low oil levels or overloads. Overload protection prevents the generator from being damaged by excessive power demand. Low-oil shutoff protects the engine by turning it off when oil levels are too low. Look for generators with these safety features to ensure reliable and safe operation.
