What Size Generator Will Run A House?

Introduction:
A power outage can occur anytime, anywhere, and your home’s energy supply can be interrupted for several hours or even days at a stretch. A generator can be a lifesaver in such situations. But finding the right generator size to power your home may seem overwhelming. In this article, we will discuss what size generator will run a house, so you can pick the right generator that perfectly meets your needs.

Understanding Generator Wattage:
A generator’s wattage determines its power output. Some home appliances and devices require a lot of power, while others require much less. The wattage of a generator must be able to handle the sum of all the devices and appliances in your house that you want to be powered. So, selecting the right-size generator for your home depends on your power needs.

Calculate Your Power Requirements

To find out your power requirement, you should make a list of all the appliances and devices you want to keep on in a power outage. Make sure you include all the essentials like lights, refrigerator, AC or heating systems, microwave, etc. Look at the product’s label for wattage requirements, or check your device’s manual for power consumption.
After you have compiled your checklist, sum up the total wattage. This will provide you with a rough estimate of how many watts you need to power your home during a power outage.

Determine the Generator Size

Once you have worked out your total wattage requirement, it’s time to determine the right generator size. As a general rule, it is better to invest in a generator with more wattage capacity than what you need. This is because a generator under strain will work harder and is more likely to wear out fast.

Small-size Generator:

If you need a generator to power a few essential household appliances, you can select a small home generator that has a power output of 3,000-4,000 wattage. This would generally be sufficient to maintain operations of the refrigerator, lights, and a handful of other small items.

Medium-size Generator:

If you want to power up more appliances at home during a power outage, a medium-size generator is the optimal choice, typically between 5,000-7,500 watts. A medium-size generator can run up to 10 lights, a heater, a portable air conditioner or a furnace, and even your home’s entertainment units. Be aware that high-wattage devices such as washing machines or a double-door refrigerator may need more power.

Large-size Generator:

If you want to power your entire household, a generator with a 10,000-12,000 wattage output will be appropriate. A high-capacity generator can keep almost everything that runs on electricity available to you, including the central air conditioner, sump pump, security system, and more.

Other Factors to Consider:

Aside from your power requirements, several other factors need to be taken into account. Some of these include:

– Fuel Type: A generator that uses gasoline, propane, or diesel fuel may be suitable for you.
– Noise Level: Noise levels vary, and a loud generator may disrupt your or your neighbor’s peace of mind.
– Portability: Depending on your need and usage, you may prefer a stationary or portable generator.

Conclusion:

Home generators come in different sizes, and the right one for your home depends on your power needs. Small, medium, or large, they all come with their pros and cons. When buying a generator, it’s always better to choose one with more wattage capacity than you need to prolong its lifespan. Consider other factors like fuel type, portability, and noise level before making your purchase. With the right-size generator, you’ll have the peace of mind of knowing you’re prepared for the next power outage.

FAQs for What Size Generator Will Run A House?

What size generator should I get for my house?

The size of the generator you need for your house depends on the amount of power your home requires. As a rough estimate, a 3,000 to 4,000-watt generator can power essential appliances like a refrigerator, lights, and a few electronics. For larger homes and more power-hungry appliances like central air conditioning, a 5,000 to 7,000-watt generator would be needed. It’s always best to consult with a professional to determine the correct size for your needs.

Can a portable generator power an entire house?

Portable generators can power an entire house, but only if they have a high enough wattage output to cover your home’s power needs. Additionally, you will need to purchase a transfer switch to connect the generator to your home’s electrical panel safely. However, standby generators are the better choice for powering an entire house as they are permanently installed, start automatically during a power outage, and have a higher wattage output.

Can I run my house on a generator for an extended period?

Yes, you can run your house on a generator for an extended period, but it is not recommended or safe to do so for a prolonged time. Portable generators are not designed for long-term use and should be turned off regularly to rest and refuel. If you require power for an extended period or frequently experience power outages, investing in a standby generator is a better solution.

What should I consider when purchasing a generator for my house?

Several factors should be taken into account when purchasing a generator for your house, such as your home’s power requirements, your budget, your location’s weather conditions, and the type of fuel you prefer. It’s best to consult with a professional to determine the correct size and type of generator for your specific needs. Additionally, it’s essential to choose a reputable brand for reliability and ease of maintenance.
