Home Generator Buying Guide: Choose the Perfect Power Solution for Your Home


Power outages can cause significant inconveniences and disruptions in your daily routine. Investing in a reliable home generator can be a practical solution to ensure your home stays powered up during emergencies and outages. This guide aims to assist you in selecting the ideal home generator to suit your needs while considering factors such as power output, fuel type, and installation requirements.

1. Assess Your Power Needs:

Before purchasing a generator, evaluate your household’s electricity requirements. This entails identifying the essential appliances and systems you wish to keep operational during an outage. You may choose a generator that can run only the essentials or one that can support your entire house. Make a list of these devices and their respective wattages to determine the required generator capacity.

2. Choose Between Portable or Standby Generators:

Portable generators are versatile, affordable, and require manual setup when needed, making them an excellent option for temporary power solutions. Standby generators are permanent installations that automatically activate during a power outage and are ideal for uninterrupted backup power.

3. Understand Fuel Types:

Generators can be powered by natural gas, propane, diesel, or gasoline, each with pros and cons in cost, efficiency, availability, and environmental impact. Natural gas and propane are commonly used for standby generators due to their clean-burning properties and lower maintenance compared to diesel or gasoline-operated models.

4. Generator Size and Output:

Determine the appropriate generator size based on your assessed wattage needs from step 1.

Home generators range from small (3kW-5kW) units suitable for essential items up to large (20kW+) systems capable of powering your whole house. Selecting a generator with sufficient output ensures that it won’t overload or shut down while running devices within its capacity.

5. Transfer Switches:

A transfer switch transfers electrical loads between the utility power and generator power. It is crucial for safely connecting your generator to your home’s electrical system. Manual transfer switches must be manually activated during a power outage, while automatic transfer switches engage and disengage seamlessly for standby generators.

6. Generator Installations:

Generator installation should always be handled by a licensed professional to ensure it meets safety codes and regulations. Proper installation, including placement and ventilation, plays an essential role in the overall system efficiency and safety.

7. Consider Noise Levels:

Generators can be noisy, which may cause disturbance to you and your neighbors. Look for options that have noise-reducing features, such as enclosures or noise barriers. Remember that local ordinances may dictate acceptable noise levels during specific hours.

8. Maintenance and Warranty:

Regular maintenance is necessary to ensure a durable and reliable generator system. Choose a trusted manufacturer that provides an extensive warranty and local dealer support for any issues or servicing needs.


Selecting the right home generator involves considering your power requirements, fuel type, generator capacity, transfer switches, installation requirements, noise levels, and maintenance. By carefully evaluating these factors, you can ultimately choose the perfect home generator to provide reliable backup power during outages and emergencies.
