Introduction
Are you preparing for a power outage and wondering what size portable generator will run a whole house? It’s crucial to choose the right size to avoid overloading your generator and damaging your appliances or electrical system. The size of your generator depends on the amount of power your home needs, including the number and type of appliances, lighting, HVAC system, and other electrical devices. In this article, we’ll guide you through the steps to determine what size portable generator you need to run your entire house.
Calculating Your Home’s Power Requirements
The first step is to calculate your home’s power requirements, which is measured in watts. You can determine your power needs by adding up the wattage of each appliance and device that you want to power with your generator. You can find this information on the label or user manual of each item, or you can use a wattage meter to measure the power consumption of your appliances.
Subheading 1: Essential vs. Optional Appliances
Not all appliances are created equal in terms of power consumption. Some are essential for survival and comfort during a power outage, while others are optional or can be turned off temporarily. You should prioritize your power needs and focus on the essential appliances first. These include your refrigerator and freezer to prevent food spoilage, your HVAC system to maintain a comfortable temperature, and some lights to navigate your home safely.
Subheading 2: Appliance Wattage Chart
To help you calculate your power needs, here’s a sample appliance wattage chart with the average power consumption of common home appliances:
- Refrigerator (700-1200 watts)
- Freezer (600-1100 watts)
- Electric stove (2100-5000 watts)
- Microwave (500-1500 watts)
- Coffee maker (900-1200 watts)
- Toaster (800-1500 watts)
- Dishwasher (1200-2400 watts)
- Washing machine (350-500 watts)
- Dryer (1800-5000 watts)
- Television (80-400 watts)
- Computer (60-300 watts)
- Furnace blower (700-1600 watts)
- Air conditioner (1500-5000 watts)
- Sump pump (600-1000 watts)
Subheading 3: How Many Watts Do You Need?
Once you’ve listed all the appliances and their wattage, you need to add up the total power consumption to determine how many watts you need. For example, if you want to power a refrigerator (1200 watts), freezer (1000 watts), furnace blower (1000 watts), sump pump (800 watts), and some lights (200 watts), the total wattage is 3200 watts.
Keep in mind that some appliances require more power to start up, known as “starting watts,” than they do to operate normally. For example, a refrigerator may need 2400 watts to start up but only needs 1200 watts to run. You should factor in these starting watts in your calculation to ensure your generator can handle them.
Subheading 4: Generator Sizing
Now that you know how many watts you need to power your home, you can choose the right size portable generator. Portable generators range in size from 1000 watts to 10,000 watts, with the most common sizes being 3000-5000 watts. The best size for your home depends on your power requirements and budget.
A 3000-watt generator can power essential appliances such as a refrigerator, lights, and a furnace blower, but not much else. A 5000-watt generator can handle more appliances, including a central air conditioning unit, but may struggle during peak usage. If you want to power your entire home and all of its appliances without worrying about overloading your generator, you’ll need a 10,000-watt generator or higher.
Conclusion
Choosing the right size portable generator to run your whole house is essential to ensure you have power during a blackout. By calculating your power requirements, prioritizing your essential appliances, and adding up the total watts, you can determine the size of the generator you need. Consider the starting watts and peak usage of your appliances and choose a generator that can handle your power needs without overloading or damaging your electrical system.

Frequently Asked Questions (FAQs) for “What Size Portable Generator Will Run A Whole House?”
1. What are the factors to consider when choosing a portable generator for a whole house?
There are several factors to consider when choosing a portable generator for a whole house, such as the size of the house, the number of electrical appliances that need power, the power requirements of those appliances, and the type of fuel that the generator uses.
2. Can a portable generator run an entire house?
Yes, a portable generator can run an entire house, but it depends on the size of the generator and the power requirements of the house. A generator with a higher wattage can power more appliances and devices.
3. What size portable generator do I need to run my whole house?
The size of the portable generator that you need to run your whole house depends on the power requirements of your appliances and devices. As a general rule of thumb, a generator with a wattage output of at least 5,000 watts can power essential appliances like refrigerators, lights, and sump pumps in a typical household, while a higher wattage output is needed for larger homes and more power-hungry appliances.
4. Can I connect a portable generator directly to my house?
Yes, you can connect a portable generator directly to your house, but it is recommended to install a transfer switch to ensure the safe use of the generator. A transfer switch allows you to safely and easily switch from utility power to generator power, and it prevents the electricity from the generator from flowing back into the utility lines.
