Buying Guide for the Best Home Generators
Choosing the right home generator is crucial to ensure you have a reliable power source during outages. The right generator can keep your essential appliances running, provide comfort, and ensure safety. To make an informed decision, you need to understand the key specifications and how they align with your needs. Here are the main factors to consider when selecting a home generator.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 20,000 watts. For basic needs like lights, a refrigerator, and a few small appliances, a generator with 3,000 to 5,000 watts may suffice. For whole-house coverage, especially if you have high-power appliances like air conditioners or electric stoves, you might need 10,000 watts or more. Assess your power needs by listing essential devices 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, and storage. Gasoline is widely available but has a shorter shelf life and can be harder to store in large quantities. Propane has a longer shelf life and burns cleaner but requires a storage tank. Natural gas offers a continuous supply if you have a gas line but may not be available in all areas. Diesel is efficient and has a long shelf life but can be more expensive and less environmentally friendly. Choose a fuel type based on availability, storage convenience, and your environmental preferences.
RuntimeRuntime refers to how long a generator can operate on a full tank of fuel. This is important for planning how often you will need to refuel during an outage. Generators with larger fuel tanks or more efficient engines will have longer runtimes. For example, a generator with a 5-gallon tank might run for 8-10 hours at 50% load. If you need continuous power for extended periods, look for generators with longer runtimes or consider models that can be connected to larger external fuel sources. Match the runtime to your expected outage duration and refueling capabilities.
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, making them easier to move. They are ideal for temporary power needs or if you plan to use the generator in multiple locations. Stationary or standby generators are permanently installed and automatically turn on during an outage. They are more powerful and convenient for whole-house coverage but are not portable. Choose based on whether you need a fixed or mobile power solution.
Noise LevelNoise level, measured in decibels (dB), indicates how loud the generator will be during operation. This is important for comfort and compliance with local noise regulations. Generators can range from 50 dB (similar to a quiet conversation) to over 100 dB (similar to a chainsaw). If you live in a densely populated area or plan to use the generator near living spaces, look for models with lower noise levels, typically under 70 dB. For remote or less noise-sensitive areas, higher noise levels may be acceptable. Consider your environment and tolerance for noise when choosing a generator.
Start TypeStart type refers to how the generator is turned on. Common options include manual recoil start, electric start, and automatic start. Manual recoil start requires pulling a cord, which can be physically demanding. Electric start uses a battery to start the generator with the push of a button, offering convenience and ease of use. Automatic start is typically found in standby generators and activates the generator automatically during a power outage. Choose a start type based on your physical ability, convenience preference, and whether you need the generator to start automatically during an outage.
