Searching for a backup power source or upgrading your generator? We recommend first learning the difference between two primary types of generators: portable and standby. Purchasing a generator is the way to go if you want to keep your home running during an outage, but it’s important to choose the right tool for the job. Let’s explore your options together.

What is a portable generator?

Portable generators provide electricity by running a gasoline, propane or diesel-powered engine. Outlets on the side of the generator allow you to plug in appliances, tools and extension cords. These units most often produce 1 kW to 10 kW of power and are best when power requirements are low or the outage is very short. Because of this, you’ll likely use a portable generator for temporarily powering fans or refrigerators during short outages at home, or for powering outdoor or remote appliances. If you’re camping, tailgating or hosting an event outside, a portable generator allows you to bring a few of the comforts of home to the great outdoors.

What is a standby generator?

Standby generators automatically power your entire house in the event of an outage whether you are home or away. As soon as the power goes out, the connected automatic transfer switch signals the generator to start. Once installed, operation is completely hands off for the homeowner. With home generator sizes from 10 kW to 150 kW and business/industrial generators up to 4,000 kW, houses big and small can stay powered and connected in even the most extreme weather or enduring outages. A standby generator is permanently installed on your property for safe, reliable whole-home backup power any time you and your family need it.

How are portable and standby generators similar?

Both portable and standby generators provide an extra source of power when you don’t have access to the electricity grid. There are a wide range of sizes and power outputs available to accommodate your needs, from powering a few essential appliances to your entire home. They both run on various fuel sources, so you have the flexibility to choose a source that fits your preferences and availability.

How are portable and standby generators different?

When the power goes out, standby generators start automatically and run on self-feeding fuel, so you don’t have to lift a finger. With a portable generator you’ll have to pull it out of storage, add fuel, run extension cords, and manually turn it on — ultimately losing precious time during an outage. Standby generators use your home’s existing natural gas or liquid propane, whereas portable generators usually use fast-burning gasoline or diesel fuel. During an outage, you’ll have to go outside to refuel your portable generator every few hours to keep it running, which isn’t safe in harsh weather conditions. In a five-day outage, a typical portable generator will consume 70 gallons of gasoline. It’s impractical and unsafe to store that much fuel at your home, and you won’t be able to get more if your local gas station is also without power.

Standby generators can power your entire home, including large appliances like your fridge and freezer, hard-wired systems such as your HVAC systems, lighting, and sump pump. They’re also professionally and permanently installed on your property for safe and hassle-free performance. Portable generators have just a few outlets, so you'll have to be selective about which appliances to power. They don’t have the capacity or connections to power HVAC systems, natural gas appliances or ceiling lights, so everyday home necessities can’t be restored. Unless you have an electrician wire a manual transfer switch, you can only plug in appliances within reach of an extension cord. For home backup power, the constant need to refuel and limited power capabilities make portable generators a less-than-ideal solution. There are also significant safety precautions that need to be observed with portable generators including:

• Operate outdoors away from air intake to avoid dangerous carbon monoxide buildup in the home

• Extension cords must be outdoor rated and sized for the distance and load they will carry

• The portable generator must be turned off with time to cool before refueling in order to avoid burn hazards

So, what generator is best for my home?

Portable generators are better suited for mobile use such as campsites, tailgates or other outdoor events where you need power for specific appliances over a short period of time. Whether it’s a scheduled outage or an unexpected storm, a whole-home standby generator alleviates all the stress usually associated with power loss. From heat and AC to hot meals and warm showers, a standby backup generator keeps your family safe and comfortable during any outage of any duration—without the hassle of extension cords or refueling.
