Power outages can be a major inconvenience and even a safety hazard, especially during the winter when temperatures drop, and heating systems stop working. Having an emergency generator can provide you with backup power and peace of mind in case of a blackout during a storm. But how do you choose the best emergency generator for your home? Here are some factors to consider:
Size and Wattage
The size and wattage of your generator determine how much power it can provide and how many appliances it can run at the same time. To calculate the wattage you need, you have to add up the wattage of all the devices you want to power during an outage. You can find the wattage of each device on its label or manual, or use an online calculator. You should also consider the starting wattage, which is the extra power needed to start some appliances, such as refrigerators, air conditioners, and pumps. The starting wattage is usually higher than the running wattage, so you need to make sure your generator can handle the peak load.
Generally, the larger the generator, the more power it can provide, but also the more space, fuel, and maintenance it requires. You can choose between portable generators and standby generators, depending on your needs and preferences. Portable generators are smaller, cheaper, and easier to move and store, but they have lower wattage and shorter run time. Standby generators are larger, more expensive, and permanently installed, but they have higher wattage and longer run time. They can also automatically start and switch on when the power goes out, and switch off when the power comes back, providing you with uninterrupted power supply.
Fuel Source
The fuel source of your generator affects its performance, cost, and environmental impact. The most common fuel sources for generators are gasoline, propane, natural gas, diesel, and solar. Each fuel source has its advantages and disadvantages, so you need to weigh them carefully before making a decision.
- Gasoline is the most widely available and affordable fuel source, but it has some drawbacks. Gasoline has a short shelf life, so you need to store it properly and replace it regularly. It is also highly flammable and volatile, so you need to handle it with care and keep it away from heat and sparks. Gasoline generators also produce more noise and emissions than other types of generators.
- Propane is a cleaner and safer fuel source than gasoline, as it produces fewer emissions and has a longer shelf life. Propane can also be stored in large tanks, so you can have a larger fuel supply and longer run time. However, propane is more expensive and less accessible than gasoline, and it can lose some of its efficiency in cold weather.
- Natural gas is another clean and convenient fuel source, as it produces fewer emissions and can be directly connected to your existing gas line. You don’t have to worry about storing or refilling fuel, and you can have a continuous power supply as long as the gas line is intact. However, natural gas is also more expensive and less powerful than gasoline or propane, and it can be disrupted by natural disasters or accidents.
- Diesel is a more powerful and efficient fuel source than gasoline, as it provides more energy per gallon and has a longer shelf life. Diesel generators are also more durable and reliable than gasoline generators and require less maintenance. However, diesel is also more expensive and less available than gasoline, and it produces more noise and emissions than propane or natural gas.
Some generators can run on more than one fuel source, such as dual-fuel or tri-fuel generators. These generators offer more flexibility and versatility, as you can switch between different fuel sources depending on availability, price, and preference. However, these generators are also more complex and expensive than single-fuel generators and may have lower efficiency and performance than dedicated fuel generators.
Battery Storage
The battery storage of your generator affects its run time and convenience. The battery storage is the amount of energy that your generator can store and use when the fuel source is not available or sufficient. For example, if you have a solar generator, the battery storage allows you to use the power generated during the day at night or during cloudy days. If you have a gas, propane, or diesel generator, the battery storage allows you to use the power generated when the fuel is abundant or cheap at times when the fuel is scarce or expensive.
The battery storage of your generator depends on its size, type, and quality. Generally, the larger the battery, the more energy it can store and the longer it can run. However, larger batteries are also heavier, bulkier, and more expensive than smaller batteries. The type and quality of the battery also affect its performance, durability, and maintenance. Some of the most common types of batteries for generators are lead-acid, lithium-ion, and nickel-metal hydride. Each type of battery has its pros and cons, such as its capacity, lifespan, charging speed, and environmental impact.
When choosing the battery storage for your generator, you need to consider your power needs, budget, and preferences. You should also check the battery specifications, such as the voltage, ampere-hour, watt-hour, and cycle life. You should also follow the manufacturer’s instructions on how to charge, use, and store the battery properly, to ensure its safety and longevity.
Other Features
Besides the size, wattage, fuel source, and battery storage, there are some other features that you may want to look for in your emergency generator, such as:
- Inverter technology: This feature converts the raw power from the generator into clean and stable power that is suitable for sensitive electronics, such as computers, TVs, and phones. Inverter generators are also quieter, lighter, and more fuel-efficient than conventional generators.
- Transfer switch: This feature allows you to connect your generator to your home’s electrical panel, so you can power your entire home or selected circuits with the flip of a switch. Transfer switches can be manual or automatic, depending on your preference and budget.
- Electric start: This feature allows you to start your generator with the push of a button, instead of pulling a cord. Electric start generators are easier and more convenient to use, especially in cold weather.
- Remote control: This feature allows you to monitor and control your generator from a distance, using a remote, a smartphone, or a computer. Remote control generators are more user-friendly and accessible, especially for people with mobility issues or disabilities.
- CO sensor: This feature detects the level of carbon monoxide (CO) in the air and shuts off the generator if it reaches a dangerous level. CO is a colorless, odorless, and deadly gas that can be produced by generators, especially if they are not properly ventilated. CO sensor generators are safer and more reliable, especially for indoor use.
Having an emergency generator can be a lifesaver during power outages, especially during the winter. However, choosing the best emergency generator for your home can be a challenge, as there are many factors to consider and options to choose from. By following the tips and guidelines in this article, you can make an informed and confident decision that suits your needs and preferences. Remember to compare different models and features, read reviews and ratings, and consult experts and professionals before making a purchase. Also, remember to install, use, and maintain your generator properly, to ensure its safety and performance. With the right emergency generator, you can enjoy uninterrupted power and comfort in any situation.
