Power outages can strike at any time, whether due to severe weather like storms and hurricanes, or issues with the local power grid. A standby generator can be a real lifesaver in such situations, providing electricity to keep your home running smoothly. But with so many options on the market, how do you determine which one is the best standby generator for your needs? This article will walk you through the key factors to consider, helping you make an informed decision.
Fuel Types: Which One Suits You Best?
Standby generators can run on various fuel types, each with its own set of advantages and disadvantages.
Natural Gas
Natural gas generators are a popular choice. They are connected directly to your home’s gas line, which means you don’t have to worry about refueling during an outage as long as the gas supply is available. This provides a continuous source of power. Additionally, natural gas is often more cost – effective in the long run compared to some other fuels. However, in the event of a major disaster, the gas supply might be shut off for safety reasons, leaving your generator without fuel.
Propane
Propane generators are another option. Propane is stored in a tank, which can be refilled. They are relatively clean – burning and can offer a good power output. Propane tanks come in different sizes, allowing you to choose one based on how long you expect your generator to run during an outage. But like natural gas, propane also has its drawbacks. If the tank runs out of fuel, you’ll need to refill it, and in some emergency situations, this might not be easy to do immediately.
Diesel
Diesel generators are known for their high power output and durability. They can run for long periods without refueling, especially if you have a large enough fuel tank. Diesel is also more stable during long – term storage compared to gasoline. However, diesel generators tend to be more expensive upfront, and the fuel can be costly. They also produce more noise and emissions compared to natural gas and propane generators.
Determining Your Power Requirements
Before buying a standby generator, you need to figure out how much power you need. This will ensure that the generator can run all the appliances and systems you want to keep running during a power outage.
Listing Essential Appliances
Start by making a list of the essential appliances and systems in your home. This usually includes the refrigerator to keep your food fresh, a heating or cooling system depending on the season, lights for visibility, and perhaps a sump pump if you’re at risk of flooding. Each of these appliances has a specific wattage requirement. For example, a typical refrigerator might need around 1000 – 1500 watts to run, while a central air – conditioning unit could require 3000 – 5000 watts or more.
Calculating Total Wattage
Once you have your list, add up the wattages of all the essential appliances. This sum will give you the minimum power output (measured in watts or kilowatts, where 1 kilowatt = 1000 watts) that your standby generator should have. Keep in mind that some appliances, like air conditioners and electric motors, require a higher starting wattage (also known as surge wattage) when they first turn on. So, if you plan to run such appliances, make sure the generator you choose can handle both the running and starting wattages.
Transfer Switches: Manual or Automatic?
A transfer switch is an important component of a standby generator setup. It’s responsible for safely switching the power supply from the utility grid to the generator and back again when the power is restored.
Manual Transfer Switches
Manual transfer switches require you to physically switch the power source. This means that during a power outage, you’ll need to go outside to the generator and flip the switch to start the generator and connect it to your home’s electrical system. Manual transfer switches are generally less expensive than their automatic counterparts. However, they can be inconvenient, especially if it’s late at night, raining, or if you’re not at home when the power goes out.
Automatic Transfer Switches
Automatic transfer switches (ATS) are a more convenient option. They are equipped with sensors that detect when the power goes out. Within seconds, the ATS will automatically start the generator and switch the power supply to it. When the utility power is restored, the ATS will switch back to the grid and shut off the generator. This seamless transition ensures that your home’s power supply is interrupted for only a very short time. While ATSs are more expensive, they offer peace of mind and greater convenience.
Noise Level: A Consideration for Residential Areas
Noise can be a significant factor, especially if you live in a residential area. Standby generators produce noise when they operate, and this could potentially disturb you, your family, and your neighbors.
Understanding Decibel Ratings
Generators are rated in decibels (dB). A typical conversation is around 60 dB, while a lawnmower might produce around 90 dB. When looking at generators, try to find one with a relatively low decibel rating. For example, some generators are designed to operate at around 70 – 80 dB, which is still noticeable but less intrusive.
Noise – Reduction Features
Some generators come with noise – reduction features. These can include sound – dampening enclosures, which are made of materials that absorb or reflect sound waves, reducing the amount of noise that escapes. Others might have special engine designs that run more quietly. If you’re sensitive to noise or live in a densely populated area, investing in a generator with good noise – reduction features is a wise choice.
Generator Enclosure: Durability and Protection
The enclosure of a standby generator is important as it protects the internal components from the elements.
Material Matters
Standby generators are often installed outside, so they need to be able to withstand rain, snow, heat, and cold. Look for generators with enclosures made of durable materials. Steel enclosures are strong and can offer good protection, but they might rust over time if not properly treated. Composite materials, on the other hand, are often corrosion – resistant and can be just as durable. They are also sometimes lighter, which can be an advantage during installation.
Ventilation
Proper ventilation is also crucial. The generator needs to have enough air flow to keep the engine cool while it’s running. Enclosures should be designed with ventilation holes or grilles that are positioned in a way that prevents water and debris from entering while allowing sufficient air circulation.
Remote Monitoring and Connectivity
In today’s digital age, having the ability to monitor your standby generator remotely can be a great advantage.
Wi – Fi and Bluetooth Connectivity
Some generators come with Wi – Fi or Bluetooth connectivity. With Wi – Fi, you can connect the generator to your home network and monitor its status using a smartphone app or a web browser. This allows you to check if the generator is running, its fuel level, and any error messages, even if you’re away from home. Bluetooth connectivity is useful for more local monitoring, such as when you’re in your yard or close to the generator. You can use a compatible device to access basic information about the generator’s operation.
Alerts and Notifications
Remote monitoring systems often come with alert and notification features. For example, you can set up the system to send you a text message or an email if the generator fails to start during a power outage, if the fuel level is low, or if there are any maintenance issues. This keeps you informed and allows you to take action quickly.
Warranty and After – Sales Support
When investing in a standby generator, it’s important to consider the warranty and the after – sales support offered by the manufacturer.
Warranty Coverage
Most standby generators come with a warranty, which can range from a few years to up to five years or more. The warranty should cover defects in materials and workmanship. Make sure you understand what is and isn’t covered by the warranty. For example, some warranties might not cover damage caused by improper installation or normal wear and tear. A longer and more comprehensive warranty can give you peace of mind, knowing that you’re protected in case something goes wrong with the generator.
After – Sales Support
Good after – sales support is also essential. This includes access to replacement parts, service technicians who are trained to work on your specific generator model, and customer service that can answer your questions. A manufacturer with a wide network of authorized service centers will make it easier and faster to get your generator repaired if it breaks down.
Conclusion
Choosing the best standby generator for your home is not a decision to be taken lightly. You need to carefully consider factors such as fuel type, power requirements, transfer switches, noise level, enclosure, remote monitoring capabilities, and warranty. By taking the time to evaluate your needs and research the available options, you can select a standby generator that will provide reliable power during outages, keeping your home comfortable and your family safe. Remember, a well – chosen standby generator is an investment that can pay off in many ways, ensuring that you’re prepared for whatever power – related challenges come your way.
