Best Standby Generator for Home Use [Buying Guide]

Before you invest money on a standby generator, selecting the right model is the crucial thing you need to do. With the best standby generator for home use, you can ensure your family is well-covered in times of power emergencies. So how do you select the right unit? You need to consider the following:

Type of fuel to use

A standby generator is a vast machine, which can run on either diesel, natural gas or liquid propane. If your home is supplied with natural gas, then you can use it to run the generator. It’s much cheaper and requires no refilling.

However, you do need to check on the pressure required to run the standby generator you’re about to buy. If it needs more, then the power company will have to provide a separate meter.

Another option is liquid propane. It’s one of many homeowners favorite since it has a longer service life and can be kept in large tanks. Another thing, liquid propane is readily available when other gases aren’t.

The last option is the diesel types, which is long-lasting and heavy-duty. They are high on price and highly touted.

Today there are fuel conversion kits you can use to transform your generator so that it can use bi-fuel or even multi-fuel. The kit comes in handy during disasters when some gases aren’t available.

Size and Capacity

Often, standby generators are massive units and come in large capacity labeled in kilowatts. To get right, you need to consider the area of installation and the amount of power you need. A massive generator in physical size will need a big installation space.

Note: You need to install the unit away from the windows and doors to avoid CO poisoning.

When it comes to power requirement, make sure that you do the right estimation for the unit to be enough to power your whole house. While performing your calculations, consider the appliances connected to the backup line. You have to add all the starting and running power for the motor-driven appliances like an AC. Once you have the total wattage, multiply it with 1.25 for safety and future needs.

Transfer switch

A transfer switch is necessary when you connect your standby generator to your home. As a smart-circuit, it switches between the backup line and the power-line to prevent back-feeding. That is ideal at avoiding damages to your precious appliances and electronics.

The transfer switch can be either automatic [preferred] or manual. The transfer switch can come with the generator, or you might need to buy it separately. I recommend you consider a model that comes with one.

License and permit

Different nations and states have regulations and requirements on what to install permanently in your home. That includes your standby generator. For a proper installation, you have to check on these state laws before buying. Also, check on the noise levels. Most of the states will need you to maintain some level of noise.

Frequently Asked Questions (FAQs)

Why do I need a transfer switch?

A transfer switch is a safety device ideal for preventing back feeding on the utility line. It allows the generator to supply power to essential appliances only. With a transfer switch, you get to avoid damages to your connected electronics.

What’s the difference between a standby generator and a portable generator?

As the name suggests, a portable generator is a movable power supply, which you can take with you wherever you go. Standby generators, on the other hand, are a fixed power supply, mostly installed inside a house or on a solid base. Additionally, standby generators are enormous in size and capacity compared to portable models.


I can rest assured you can now buy the model you want and which meets your entire requirement. After reading all the above info, you can agree with me that these models are quite similar. Do not get confused again; use the buying guide to buy the model for your specific needs. Good Luck!
