When it comes to ensuring your home has a reliable power source during an emergency or when your primary power supply goes out, a generator is one of the best investments you can make. Whether it’s for a temporary power backup during storms or a long-term solution, selecting the right generator for your needs can seem overwhelming. However, with the right knowledge and guidance, you can make an informed decision.
In this guide, we will walk you through everything you need to know about buying a generator for your home, from understanding your power needs to choosing the right type and fuel source, as well as installation and maintenance. Let’s get started.
When considering buying a generator, you have two main options: purchasing from a local dealer or buying it online. Both methods have their advantages.
Local Dealer Purchase: Local dealers often provide on-site evaluations of your power needs, give you personalized recommendations, and offer installation services. You also get the benefit of seeing the generator in person, which is especially useful for large standby generators.
Online Purchase: If you are confident about your needs and know the specifications of the generator you want, buying online can often offer better prices and convenience. However, it’s important to ensure the seller provides good customer service and return policies in case the product doesn’t meet your expectations.
To buy the right generator, the process involves:
Calculating Power Requirements: The first step in purchasing a generator is determining how much power you need. This involves adding up the wattage requirements of the appliances and devices you want to power during an outage.
On-Site Assessment: For home standby generators, it’s a good idea to have a professional come to your home and assess your power needs. They will help you calculate how much wattage is required to keep your home running smoothly during an emergency.
Installation: After choosing a generator, the installation process begins. For portable generators, this may just involve setting it up outside and connecting appliances. However, a standby generator typically requires professional installation, including electrical work and fuel line connections.
One of the most important factors in selecting a generator is understanding your power needs. To calculate this, follow these steps:
List the Appliances: Make a list of all the appliances and devices you want to power during an outage. This could include refrigerators, lights, computers, heating or cooling systems, etc.
Calculate Wattage: Each appliance has a wattage rating, which can be found on the label or in the user manual. Add up the wattages of all the appliances you plan to run at the same time.
Consider Starting Wattage: Some appliances, such as refrigerators and air conditioners, require more power to start up than they do to run continuously. This is called “starting wattage.” Be sure to factor in the starting wattage for these appliances to avoid overloading the generator.
Generators come in several types, each suited to different needs:
Portable generators are typically smaller and more affordable than home standby units. They are ideal for short-term power outages or for use during outdoor activities like camping.
Pros:
Affordable
Easy to transport
Ideal for short-term power needs
Cons:
Require manual setup
Limited power output
Home standby generators are larger, more powerful units designed to provide automatic backup power for your entire home in case of an outage. These units are permanently installed outside the home and automatically turn on when the power goes out.
Pros:
Automatic operation
Powers your entire home
Higher power output
Cons:
Expensive
Requires professional installation
Inverter generators are a type of portable generator that provide a more stable power output and are quieter than conventional models. They are ideal for powering sensitive electronics such as computers and TVs.
Pros:
Quiet operation
Stable power output
Compact and lightweight
Cons:
Higher cost than standard portable generators
Lower power output compared to home standby units
Choosing the right generator fuel type is essential for efficiency, convenience, and availability. The most common fuel types are:
Gasoline-powered generators are the most common, especially for portable units. They are widely available, easy to use, and relatively affordable.
Pros:
Widely available
Easy to use
Lower initial cost
Cons:
Shorter run time
Gasoline can deteriorate over time if not used
Diesel generators are more fuel-efficient than gasoline and are generally more durable. They are ideal for large homes or commercial use.
Pros:
More fuel-efficient
Longer lifespan
Better for larger power needs
Cons:
Higher initial cost
Noisier than gasoline generators
Natural gas generators are often used for home standby generators because they are connected to your home’s gas line and don’t require refueling.
Pros:
Continuous power supply (as long as gas is available)
Cleaner burning than gasoline or diesel
Lower maintenance requirements
Cons:
Higher initial installation cost
Limited availability in some areas
Propane generators are clean-burning and can be stored for long periods, making them ideal for emergency situations.
Pros:
Clean-burning
Easy to store
Works well in emergencies
Cons:
Requires a propane tank
Higher initial cost than gasoline
Home standby generators require professional installation, including electrical connections and possibly gas line connections. It is crucial to hire a licensed professional to ensure that the installation complies with local regulations and is safe to operate.
Maintaining your generator is vital for ensuring that it operates when needed most. Regular maintenance includes:
Changing the oil
Cleaning or replacing the air filter
Checking the fuel system
Testing the generator periodically
Refer to the manufacturer's manual for specific maintenance requirements and intervals.
The cost of a generator depends on several factors, including type, size, and fuel source. Portable generators generally cost between $500 and $2,000, while home standby generators can range from $3,000 to $10,000 or more, depending on the size and installation costs.
Installation Fees: Home standby generators require professional installation, which can add an additional $2,000–$4,000.
Fuel Costs: Depending on the fuel type, you will need to budget for ongoing fuel costs.
Maintenance: Regular maintenance is essential to keep your generator running smoothly, and some models may require additional parts or repairs over time.
To determine the right size, calculate the wattage required for all appliances you want to power simultaneously. Ensure the generator you choose can handle both running and starting wattages.
The runtime of a generator depends on its fuel source and size. Gasoline generators typically run for 8–12 hours on a single tank, while diesel or natural gas generators can run for much longer.
For portable generators, you can set them up yourself, but home standby generators should always be installed by a licensed professional to ensure safety and compliance with local codes.
Regular maintenance involves checking oil levels, replacing the air filter, testing the generator regularly, and maintaining the fuel system. Refer to the manufacturer’s manual for specific instructions.
If you live in an area prone to power outages or need a backup power source for essential appliances, investing in a generator is worth it. It provides peace of mind during emergencies and ensures that you have power when you need it most.
Choosing the right generator for your home is a crucial decision that depends on your specific power needs, budget, and the type of generator that best suits your situation. Whether you opt for a portable, standby, or inverter generator, the key is understanding your needs and ensuring that the generator can meet them effectively.
