What Size Backup Generator Is Right For Your Home?

what size backup generator


The size of a backup generator is largely dependent on your home’s energy requirements. Consider how many appliances will need to be powered during a power outage, and how many outlets your home has. Your generator’s output must be large enough to power those appliances. Also consider the type of fuel it uses.

It’s important to choose a home backup generator that has enough power to provide uninterrupted power. It should also prevent back feeding of electricity, which can cause fires and damage to electronics. To make sure your home’s generator can meet your electrical needs, you can hire a professional to calculate the amount of electrical load you require.

A home backup generator can be connected to every circuit in your home, or only to essential ones. Essential circuits include gas furnace blower motors and refrigerators, kitchen receptacles, water pumps, and more. Depending on the size of your house, you may need to choose a larger generator to power more important appliances.


The need for a backup generator cannot be underestimated, especially in a business environment. Businesses need energy to run properly and a power outage could shut down the entire building. A sudden power failure could also damage equipment replacement can be costly. A commercial backup generator can save you money and provide a reliable source of power.

Commercial backup generators can be run on diesel, propane, or natural gas. Diesel is a convenient fuel source for commercial backup generators because it is readily available and can be stored on-site for up to two years. The fuel costs are low and it is also environmentally friendly. A backup generator powered by natural gas is much safer for business owners than one powered by gasoline.


Portable backup generators are extremely helpful in case of power outages. You can set them to automatically turn on when there is no power. This way, your home will have near-constant power and you can still run your appliances. The portable units can be easily transported and used anywhere. They are also very energy-efficient and come with a decent warranty.

Portable backup generators come in a variety of sizes. The size you need depends on your needs and the size of your house. You should also decide which circuits are essential.

Electricity demand

If you have a backup generator installed, it’s probably a good idea to consider how much electricity it would consume in case there is a power outage. However, you should know that the cost of electricity isn’t the only consideration for purchasing a generator. The cost of fuel can also affect your decision. Fortunately, there are many ways to cut your power bill while ensuring that you have electricity during a power outage.

Using a backup generator can also help you earn incentives through demand response programs. These programs offer incentives to large energy users who can reduce their demand during times of grid instability. These programs allow back-up generator users to earn even more money by transferring the load from the grid. Additionally, demand response participants are notified ahead of time when the grid is experiencing problems and can prepare accordingly.

Wattage rating of generator

When purchasing a backup generator, you should know what kind of power it can provide. There are different power ratings, such as ISO 3046, BS 5514, and DIN 6271. Knowing which one is right for your needs will help you determine the amount of power you’ll need to run your appliances.

To find the right wattage rating for your home, you can use the chart below. However, be sure to consider that different appliances and tools require different watts. You can also use a wattage meter to get a more accurate reading. Choosing a backup generator that has the right wattage rating will protect your entire home in an emergency.

Another thing to consider when purchasing a backup generator is its size. If you have a small home, you may want to choose a smaller wattage rating. You also want to consider the type of fuel the generator will run on. A diesel-powered generator is more efficient than gasoline and is a better choice if your generator is used sporadically. Also, propane is a great fuel source for backup generators because it doesn’t degrade when stored.
