Power outages can happen at any time, leaving you in the dark and without essential appliances. A home generator can provide the backup power you need to keep your life running smoothly. But with so many options available, how do you choose the right one? This guide will walk you through everything you need to know to pick the perfect generator for your home.
Understanding Your Power Needs
Before you start shopping for a generator, it’s important to understand your power needs. This will help you determine the size and type of generator that’s right for you.
Calculate Your Total Wattage
Start by making a list of all the appliances and devices you want to power during an outage. Include everything from your refrigerator and lights to your HVAC system and electronics. Next, find the starting and running wattage for each item. The starting wattage is the power needed to start the device, while the running wattage is the power needed to keep it running.
Add up the running wattage of all the items you want to power simultaneously. This will give you the total wattage your generator needs to handle. Don’t forget to account for the starting wattage of devices with motors, like refrigerators and air conditioners, as they require extra power to start up.
Consider Your Power Priorities
If you don’t need to power your entire home, consider prioritizing essential appliances. For example, you might want to keep your refrigerator, lights, and sump pump running but can do without your dishwasher or washing machine. This approach can help you choose a smaller, more affordable generator.

Standby generators come with an automatic start feature that turns the generator on as soon as a power outage is detected. This is a convenient option if you want uninterrupted power without manual intervention.
Electric Start
Some portable generators come with an electric start feature, which allows you to start the generator with the push of a button. This is easier than pulling a recoil cord, especially in cold weather.
Fuel Gauge
A fuel gauge is a useful feature that lets you monitor the fuel level in your generator. This helps you avoid running out of fuel during an outage.
Multiple Outlets
Generators with multiple outlets allow you to power several devices at once. Look for a generator with a variety of outlet types, including standard 120V outlets and 240V outlets for larger appliances.
Noise Level
Generators can be noisy, so consider the noise level if you live in a quiet neighborhood or plan to use the generator for camping. Inverter generators are generally quieter than traditional portable generators.
Portability
If you need a portable generator, consider its weight and whether it has wheels and handles for easy transport. Larger generators can be heavy and difficult to move.
Sizing Your Generator
Choosing the right size generator is crucial to ensure it can handle your power needs without overloading.
Small Generators (1,000-3,000 Watts)
Small generators are ideal for powering a few essential appliances, such as a refrigerator, lights, and a small window air conditioner. They are also a good option for camping or tailgating.
Medium Generators (3,000-7,000 Watts)
Medium generators can power more appliances, including a sump pump, microwave, and larger window air conditioner. They are a good choice for smaller homes or those who don’t need to power their entire house.
Large Generators (7,000-15,000 Watts)
Large generators can power an entire home, including central air conditioning, electric water heaters, and large appliances. They are typically standby generators and require professional installation.
Safety Considerations
Generators can be dangerous if not used properly. Follow these safety tips to protect yourself and your home.
