What Size Portable Generator Will Run A House?

Portable generators are becoming more and more popular as a backup source of power during a power outage. However, one of the most important things to know before purchasing a portable generator is how much power it can provide. Knowing the size of generator you need to power your home can be a bit overwhelming, but we’ve got you covered. In this article, we’ll answer the question, “What size portable generator will run a house?”

Understanding Generator Size

In order to determine what size portable generator you need, you must first understand how generator size is measured. Generator size is measured in watts (W) or kilowatts (kW). The wattage of a generator refers to the maximum amount of power output it can produce. When shopping for a portable generator, you may see terms like starting watts and running watts. The starting watts refer to the amount of power needed to start up an appliance, while running watts refer to the amount of power needed to keep it running.

Calculating Your Power Needs

Now that you understand how generator size is measured, the next step is to calculate your power needs. This means determining the total wattage required to power all of the essential appliances and electronics in your home.

To do this, you’ll need to make a list of all the appliances and electronics you want to power in the event of an outage. Next, you’ll need to determine the starting watts and running watts for each item on your list. This information can usually be found in the owner’s manual or on the appliance itself.

Once you have this information, add up the total running watts and starting watts for all the items on your list. This will give you a total wattage requirement for your generator.

Choosing the Right Generator Size

Now that you know your total wattage requirement, you can choose a generator size that can meet your needs. As a general rule of thumb, a 5,000 to 7,000-watt generator should be sufficient for most homes. This size generator can power essential appliances such as the refrigerator, lights, and perhaps a few other small items like a television or computer.

If you have larger appliances or more electronics, you may need a larger generator. In general, a 9,000 to 10,000-watt generator can power most homes with ease. If you have a larger or more complex home, you may need a generator with a higher wattage output.

Other Factors to Consider

When choosing a portable generator, it’s important to consider more than just wattage. You also need to consider the fuel type, run time, noise level, and safety features.

For fuel type, you can choose between gasoline, propane, or diesel. Propane and diesel are typically more expensive but may be more efficient in the long run. Run time refers to how long the generator can run on a full tank of gas or propane. Noise level is also important, especially if you plan to use your generator in a residential area. Look for generators that have a noise level of 60 decibels or lower. Finally, safety features should also be considered, such as automatic shut-off and circuit breakers.

In Conclusion

In conclusion, determining what size portable generator you need to power your home requires a bit of math and research. Consider the essential appliances and electronics you need to power, calculate your total wattage requirement, and choose a generator size that can meet your needs. Don’t forget to also consider fuel type, run time, noise level, and safety features when shopping for a portable generator. With the right generator, you can ensure that your home stays powered and comfortable during a power outage.
