Power outages can happen when you least expect it. Typically, it comes as a result of severe rains during a storm or snow during winter. But it can also happen when lightning strikes and when repairs have to be done if a tree snags an electrical line. But no matter what the cause is, you need to be fully prepared.

One of the best ways for you to prepare for a power outage is by making sure that you have a generator in your own home. Generators can help you get electricity to power up a wide array of home appliances. It can be used to keep your family safe, comfortable and even entertained during a power outage.

Depending on how big your generator is you can actually use it to power up basic appliances and even your entire home. Small generators can power up your lights and other small devices, while large ones can power up ACs and heaters. Here’s what you need to know about generator sizes for your home.

Consider The Wattage Of Our Appliances

So you will know what size you should get for your home, you will first have to check the wattage of the appliances that you want to run in your home with the help of the generator. When it comes to wattage, you will have to consider both the running and the surge watts of each appliance or electronic device.

Running watts is the power that an appliance needs to keep on running, but surge watts is the power it needs to turn on. Although it only happens during starting, you need to allocate enough power for the surge watts so you can avoid overloading your unit. Different devices have varying watt requirements.

For example, a refrigerator can demand 500 running watts and 750 surge watts. A microwave needs to run on 1000 watts and large ones can also have 2000 surge watts. You will have to make a list of all the appliances that you want to run during a power outage including their entire surge and running watts.

In some cases, you might have to run more than one appliance at the same time. You will have to list all the appliances that you need to run in an outage and you will need to have the sum of all their running and surge watts so you can choose a generator that can allow you to use them all without overloading.

Keeping Up With The Demands

Now that you already know what appliances you want to turn on using the generator during a power outage, you will have to match your needs with a generator that can keep up with your demands. In most cases, homeowners will only need to have a small, portable generator with 1000 – 3000 watts.

This is of course, if you only plan on running the basic appliances such as lights, refrigerators and televisions. If you need something a bit more powerful, you can opt for a medium sized portable or stationary generator that can provide you with 5,000 – 8000 watts to include your comfort needs.

These generators can be used to run the basic appliances plus other appliances such as portable heaters, entire heating systems as well as computers. You can also opt for an even bigger generator with a larger power output. You can actually buy a generator that can provide you with as much as 10,000 watts.

This large generator can be used to power up all of the previously mentioned electronic appliances plus even more lights, an electric range, centralized air conditioning systems and more heaters. What’s more, you can even go further by opting for a large stationary unit that can give you 10,000 – 15,000 watts.

Instead of just powering up appliances, this generator can be used to power up entire homes. During a power outage, you can use this generator and make everything seem like your house has not been affected by it. Of course, this generator will also produce a lot of noise and consume a lot of fuel.

If you want to know what size of generator you should get for your house, you will have to check your own needs first. By making a list of all the appliances that you want to power up during an emergency or an outage, you can prioritize which appliances can be considered vital and which ones are for comfort.

You will then have to decide whether you want a generator that can help you power up only the basic appliances or whether you want a generator that can also help you get additional comforts. You can also decide to get a generator that is large enough to power up all of the appliances in your own home.

Of course, you should understand the fact that these generators will use up fuel depending on how many watts they are designed to produce. While bigger ones might easily be able to provide enough power for the entire home, these huge machines are gas guzzlers and they can also be quite noisy.
