How Big of a Generator Do You Need?

When it comes to standby generators, size definitely matters. If you are looking for one for your home or business, you need to make sure you get the right size generator. Otherwise, you might end up with one that is either too small or too big. Here are some considerations to help you figure out what size generator you need, and some tips on choosing the best one for your needs.

Number and Type of Devices You Want to Operate

The size of the generator you need will depend on the number and type of devices or appliances you want to operate. If you just need to power a few lights and a small TV, then a small generator should do the trick. However, if you need to run an air conditioner, refrigerator, and several other large appliances, you’ll need a larger generator to power everything simultaneously.

When determining the right generator size, keep in mind that certain appliances require more power than others to operate. Experts in generator installation in Wellesley, MA note that, for instance, an air conditioner may require a large amount of electricity to start up but needs less power when it’s already running. So, you need a generator that can run multiple appliances safely.

Total Wattage of Your Home’s Appliances

The total wattage of your appliances is the number you are ultimately looking for here. It will help you determine just how big a generator is needed to power everything in your home. This total wattage can be calculated by totaling up all the individual watts of each appliance that needs to be powered during an outage and adding them together. 

With a clear picture of your wattage needs, you can begin to look at the different generator sizes that are available on the market. Some people may only need a small portable generator for occasional outages, while others who experience more frequent power losses may require a standby or whole-house generator. Consult a qualified electrician to help you calculate your wattage needs.

Consider How Often You Would Use a Generator 

If you only need a generator for occasional use, such as when the power goes out, then you probably don’t need a large or expensive one. A small, portable generator should do the trick. However, if you plan to use a generator regularly – for example, to power your home during an extended outage – then you’ll need something larger and more expensive.

To ensure reliable power, you’ll want to hook a larger generator up to your home’s electrical system. A good generator should use no more than 90% of its capacity at any time, so be sure to size it appropriately. Factors like how long the outage is expected to last and the type of climate you live in should be kept in mind as you make your decision.

Determine the Best Size for Your Needs

Now that you know the number and type of devices you have, their total wattage, and how often you would use a generator and for how long, it’s easier to determine the right size for your needs. As for the type of generator you should buy, there are two options: A stationary or portable generator. A good rule of thumb is that if your power outages last longer than 72 hours, choose a stationary unit because its size and wattage are better suited for longer, continuous use. 

f your power outages are shorter than 72 hours, consider a portable unit because it is easier to transport and store when not in use. If you’re looking for peace of mind, consider a whole-house generator that automatically turns on when the power goes out and shuts off when it’s restored. It requires a significant initial investment but is perhaps the best solution for homeowners who want to ensure they always have backup power when they need it. 

Consider Your Options Carefully

At this point, you can determine which generator will work best for your situation. If you’re still not sure, talk with a professional to help find the perfect fit for your home. Also, consider your options and budget carefully. The more power you need, the more expensive your generator will be. You may have other questions about which model is right for you or how to install it on your property – consult the professionals for more information on your specific needs.
