Choosing the Perfect Home Generator: A Simple Guide

• Power Requirements: Before making a purchase, it’s crucial to understand your home’s power needs. Start by listing the wattage requirements of essential appliances such as refrigerators, air conditioning units, sump pumps, medical devices, water heaters, and space heaters, as these tend to consume the most power. Many manufacturers offer online wattage calculators to help you estimate the size of the generator you need. Alternatively, you can calculate the required wattage manually by noting the ‘starting watts’ and ‘running watts’ indicated on each appliance. Remember, ‘starting watts’ refer to the initial surge of power needed to start the appliance, while ‘running watts’ are what the appliance needs to keep running. If ‘starting watts’ aren’t specified, a general rule of thumb is to multiply the ‘running watts’ by three. After calculating the starting watts for each appliance, add them together and multiply the total by 1.5 to incorporate a safety margin. Typically, a small to medium-sized U.S. household will require a generator with an output of 5,000 to 7,500 watts, though many models offer outputs ranging from 7,500 to 10,000 watts.
• Size and Noise: The physical footprint and noise level of the generator are important considerations, especially if you have limited space or prefer a quiet environment. The larger models typically measure around 30 inches by 30 inches by 48 inches, while smaller models are closer to 24 inches by 24 inches by 36 inches. According to NFPA codes, generators should be placed at least five feet away from any home openings like doors and windows. However, smaller generators can be installed as close as 18 inches from your home’s exterior wall, but it’s always wise to check local codes as they might have different requirements. Noise is another factor to consider. Most generators operate within the range of 60 to 70 decibels, similar to the sound level of a running vacuum cleaner. A generator’s noise level is particularly important if it will be placed near living areas.
• Fuel Type: The fuel type of your generator can affect its convenience and performance. The models listed typically run on liquid propane (LP), natural gas (NG), or both. Dual-fuel models offer flexibility, allowing you to switch between fuel types without the need for tools. Propane is known for its affordability and clean burn, leaving minimal contamination. It’s available in various container sizes, and some homes even have permanent propane tanks installed. On the other hand, natural gas generators can be directly connected to your home’s gas line, providing a virtually unlimited fuel supply. However, natural gas is less energy-efficient than propane and will produce less power. Additionally, a generator running on natural gas is still dependent on the gas grid for backup power.
• Purchase Price: While a home generator is a long-term investment, it’s essential to choose a model that fits within your budget. Generally, generators with a higher kilowatt output come with a higher price tag. Consider the initial purchase price as well as long-term operating and maintenance costs when making your decision.
• Operating Temperature Range: The operating temperature range is a critical factor, especially in extreme climates. Smaller generators, usually under 20 kW, are typically air-cooled, while larger models tend to have liquid cooling systems to maintain a stable temperature regardless of the outdoor conditions. Most generators function optimally in temperatures ranging from 32°F to 100°F. If you live in an area with freezing temperatures, consider a model with a cold-weather kit, including a battery heater and an oil heater, to ensure smooth operation. Be aware that very high temperatures can significantly reduce a generator’s efficiency.
• Warranties: Lastly, pay close attention to the warranty offered with the generator. Warranties can vary significantly, with the industry standard being a limited 5-year warranty covering parts and repair labor. Some manufacturers offer extended coverage for an additional year or two, and extended warranties of up to ten years are often available for purchase. Make sure to read the warranty details thoroughly to understand what is covered, under what circumstances the warranty service is triggered, and what is excluded. It’s common for manufacturers to offer different warranty lengths for various components and to specify what’s protected and what isn’t.

By carefully considering these factors, you’ll be well-equipped to choose a home generator that not only meets your immediate power needs but also aligns with your long-term expectations for reliability, convenience, and peace of mind.

Why a Home Generator is a Smart Choice

1. Home generators kick in automatically when the power goes out, thanks to electric start and automatic transfer switches (ATS). No manual starting or remote controls needed – it’s all seamless.
2. For generators above 5,000 watts, an ATS is a must. It not only switches your power source from the grid to the generator during outages but also ensures the safety of the city’s grid. Load transfer switches (50-amp and 100-amp) handle essential circuits, while a 200-amp service disconnect transfer switch can power your entire home.
3. Home generators dwarf portable ones in power capacity, offering 10,000 to 50,000 watts or more. This means not just keeping your crucial appliances running but potentially supporting your neighbors too.
4. Permanently installed and often running on liquid propane or natural gas, home generators negate the need for manual setup or fuel trips. They’re ready to go, rain or shine.
5. Keep tabs on your generator’s health with remote monitoring. Whether through an app or a service, you’re always in the loop about its status and maintenance needs.
6. Protect your generator from overload with smart load management. It prioritizes power to essential systems, ensuring your generator runs efficiently and your crucial appliances remain powered.
