The Ultimate Guide to Selecting a Home Standby Generator


Power outages can be a major inconvenience, especially if they last for an extended period. While portable generators are a popular short-term solution, a home standby generator is a robust, long-term investment that can provide uninterrupted power to your home, keeping your lights on and your appliances running smoothly.

However, choosing the right home standby generator is a critical decision that involves several factors, including your power needs, fuel source preferences, and local regulations. In this article, we will offer you a comprehensive guide on how to select the ideal home standby generator for your needs and provide you with valuable tips to ensure you're making the right choice.


Understanding Your Power Needs

The first step in choosing a home standby generator is assessing your power needs. Take a comprehensive inventory of the critical appliances and systems in your home that you would like to keep powered in the event of an outage. This can include lights, refrigerators, HVAC systems, sump pumps, and medical equipment, if applicable.

Once you have your list, calculate the total wattage required to power these devices simultaneously. You can find the wattage information on the labels of most appliances or in their user manuals. It's important to account for the starting watts, which are typically higher than the running watts for items with electric motors, like a refrigerator or a well pump.

With your power needs established, you can confidently determine the size of the generator that will accommodate your requirements.

Fuel Sources: What Works for You?

Home standby generators are typically powered by one of several fuel sources, each with its own set of advantages and considerations:

Natural Gas

Natural gas is a reliable and convenient fuel source for a standby generator. If your home has an existing natural gas line, installation is relatively simple, and there's no need to worry about refueling.


Propane offers similar benefits to natural gas, especially if your home does not have access to a natural gas line. Propane tanks can be installed on your property, and many suppliers offer automatic refilling services to ensure you never run out of fuel.


Diesel generators are robust and efficient, often chosen by those with larger power needs or specific industry requirements. However, diesel fuel can be more hazardous to store and transport.

Bi-Fuel and Tri-Fuel

Some generators offer the ability to run on two or three fuel sources, allowing for greater flexibility. These options can be a good compromise for those who want the security of multiple fuel sources without the cost of a whole-house diesel generator.

Consider not only the availability and convenience of the fuel source but also the environmental impact and associated costs over time.

Managing Load Priorities with Transfer Switches

A transfer switch is an essential component of a home standby generator system. This device detects when the power from your utility company has been interrupted and automatically transfers power to the generator. When utility power is restored, the switch turns off the generator and switches back to the utility power source.

There are a few different types of transfer switches available, and the type you choose will depend on your preferences and the complexity of your system.

A standard transfer switch can be less expensive and is suitable for most smaller systems, while a managed or load-shedding transfer switch can prioritize different circuits or loads, helpful if your generator's capacity is limited.

Generator Placement and Installation

The placement and installation of your home standby generator are crucial for its safety and optimal performance. Generators need to be installed outside your home and away from vents, windows, and doors to prevent carbon monoxide from entering your home.

Most generators come with a pre-fabricated pad or a mounting system that ensures the generator is level and secure. The installation should also include proper ventilation to keep the generator cool, and the local electrical code should be followed to ensure the connection to your home's electrical system is safe and compliant.

Always hire a professional electrician to install your generator to ensure it is done safely and correctly. If you're looking for electrical contractors in Apopka, FL, contact Spectrum Electric Inc for a reliable and experienced team to handle your generator installation.

Smart Features and Connectivity

Modern home standby generators often come with smart features that can make them easier to monitor and operate. Some generators can be connected to a mobile app, allowing you to check the status of your unit, receive alerts, and even start or stop the generator remotely.

This connectivity can be especially useful if you're away from home and want the peace of mind that your generator is operational. Be sure to consider if these features are important to you and if the extra cost is worth the convenience.

Generator Maintenance

Like any mechanical system, a home standby generator requires regular maintenance to ensure it will operate when you need it. Maintenance tasks typically include changing the oil, checking the air filter, and inspecting the spark plugs. Some homeowners choose to establish a maintenance contract with their generator installer or an authorized service provider to handle these tasks regularly.

Understand what the maintenance requirements are for the generator models you are considering, and factor this into your decision-making process, including ongoing costs and the availability of service providers in your area.

Regulations and Permitting

Before installing a home standby generator, it's essential to check local regulations and permitting requirements. Depending on where you live, you may need to obtain specific permits, adhere to noise restrictions, or meet zoning requirements.

Researching these regulations early in the process can help you avoid headaches down the line and make sure your new generator complies with all the necessary legalities.


Final Thoughts

Selecting the right home standby generator is a significant decision that involves careful planning and consideration. By understanding your power needs, researching fuel sources, managing load priorities, and addressing important installation and maintenance considerations, you can ensure that your home standby generator will keep your home powered in times of need.

Remember, when it comes to any aspect of generator selection or installation, always consult with a professional to get the best outcome for your home and family.
