There are a lot of factors to consider when choosing a generator that can run your entire home during a power outage. With varying wattages, fuel types, and capabilities, it can be overwhelming to make an informed decision. In this article, we’ll explore what wattage a generator needs to have to run a whole house and factors to consider when choosing the right generator.
What Wattage Generator is Needed?
The wattage required to power a whole house varies based on its size, the number of appliances being used, and the type of fuel power the generator. Typically, a generator that has a wattage of 5000 to 7500 can power most essential appliances and systems in a home.
A generator’s wattage indicates how much power it can produce, and this power is in watts. To determine the wattage you need for your home, you’ll want to calculate the starting wattages and running wattages of all of your appliances, systems, and lighting. You can find this information on their labels, manuals or through an online calculator.
The starting wattage is the amount of power needed for the appliance to start, and running wattage is the wattage required to keep it running. Add all the starting wattages and running wattages together to get your total wattage requirement. This will give you a rough idea of the wattage your generator needs to produce to run your household.
Factors to Consider When Choosing a Generator
When purchasing a generator, there are several factors you’ll want to consider. Here is a closer look:
Fuel Source
There are three types of fuel generators use: propane, gasoline, and diesel. Propane generators are cleaner than gasoline or diesel, and the fuel is stored in tanks that can sit for long periods without going bad. Gasoline generators are the most common, but fuel can go bad within a few months if not treated with stabilizers, and they produce the most emissions. Diesel generators are often the most fuel-efficient of the three, but they’re more costly upfront and require frequent maintenance.
Size of the Generator
Generators come in different sizes and shapes, so it’s essential to determine how portable you need your generator to be. Smaller generators are more portable, and they’re easier to store when not in use, but they won’t power your entire home. Larger generators are generally stationary, and they’re installed permanently outside your home on a pad.
Noise
The noise level is an important consideration if you’ll be using the generator in a residential area. Some generators are quieter than others, and to some people, even a slight hum can be disruptive. Consider purchasing a generator that comes with noise-reducing features.
Conclusion
When the power goes out, a generator can provide a lifesaving backup source of power for your home. By understanding the wattage requirements for your household and important factors to consider when purchasing a generator, you’ll be better equipped to select the right generator for your needs. It’s always essential to read reviews and speak with professionals before making a purchase to avoid unnecessary expenses and under-powering your home during an emergency situation.

Frequently Asked Questions
1. What is the minimum wattage needed to run a whole house generator?
The minimum wattage needed to run a whole house generator depends on the size of your home and the appliances you want to power. Generally, a generator with 3,000 to 4,000 watts is sufficient to run selected appliances, while a generator with 5,000 to 7,500 watts can provide enough power for an entire household.
2. What appliances can a 3,000-watt generator run?
A 3,000-watt generator can typically power a refrigerator, a few lights, a TV, and small electronics such as laptops or cell phones. However, it may not be able to handle certain high-wattage appliances such as air conditioning units or electric ovens.
3. Can a 4,000-watt generator run a well pump?
Whether or not a 4,000-watt generator can run a well pump depends on the depth of the well and the pump’s horsepower. A 4,000-watt generator can generally handle a shallow well pump with 1/3 horsepower or less. Deeper wells or more powerful pumps may require a larger generator.
4. What size generator is needed for a whole house air conditioner?
A whole house air conditioner typically requires a generator with a minimum of 8,000 to 10,000 watts to run. However, larger air conditioning units may require a generator with 12,000 to 13,000 watts or more. It’s important to consult with a professional to determine the necessary wattage for your specific HVAC system.
