How much power does a house use in a day?
How many watts does an average home use? According to the Energy Information Agency (EIA), the average American home uses an average of 10,715 kilowatt-hours (kWh) of electricity per year. That's 29,360 watts (W) per day, which can be divided by 24 hours to get an average of 1,223 W to power a home throughout the day.
How many watts does it take to power basic items in an average size house? In a typical home, essential items will average 5000 – 7500 watts of power to run.
Average Home Energy Consumption. According to data from 2020, the average amount of electricity an American home uses is 10,715 kilowatt-hours (kWh). If you divide this number by 12 (months in a year), the average residential utilities customer uses 893 kWh per month.
For our calculations we have used the following annual energy usage amounts which are based on industry figures: 1 or 2 bedroom house/flat - gas usage of 8,000kWh and an electricity usage of 1,800kWh. 3 or 4 bedroom house - gas usage of 12,000kWh and an electricity usage of 2,900kWh.
A smaller house in a temperate region would consume around 210-kilowatt hours (kWh) per month. Whereas a larger house where air conditioners require the most energy might use 2,000 kWh or more. The typical home uses 900 kWh per month. That works out at 1.25 kWh every hour or 30 kWh per day.
A 7,500-watt generator is generally a good size, unless you have a very large home or want to run every appliance you have on the generator. It can handle most of your household appliances, although it's a good idea to balance what you run at the same time.
Its starting watts will vary depending on the brand and model of each generator, but based on our experience the range is somewhere between 8500 – 10000 surge watts. Just don't expect to run your whole house on this machine simultaneously as this will require a lot more power than any 8000 watt generator provides.
Typically, a 3 bedroom house is a medium energy usage household, which means that you might use up to 3,100 kWh of electricity in a month. There are several things that consume high amounts of energy in your home.
At 12,500 starting watts and 10,000 running watts, this unit can handle it all in an outage – lights, refrigerator, modem/router, security system, window AC, furnace blower, TV, computer, phone charger and more.
Yes, depending on where you live, a 10kW solar system would be enough to power the average home of a family of four and enough to power the average 2,000 square foot home in the United States.
Is 12 kW enough to run a house?
Though the 10kW – 12kW home standby generator likely won't power your whole home depending on its size, it's certainly enough to handle “the essentials” such as well pumps, appliances, etc., plus a little more in the event of a power outage.
Partial House - 14 to 20kW
Typically will cover all of the items in your home you NEED to get through a power outage, plus some areas you WISH had power to make it comfortable: Essentials: Sump Pump.

That means the average household electricity consumption kWh per day is 28.9 kWh (867 kWh / 30 days).
For example, a single-person home will typically use about 8–12kWh per day on average, while a household of five people with a pool could use 30–40kWh per day.

You may not have known, but you are perfectly able to cover the needs of a small home with a 2kW solar panel system. Systems like this are able to produce the energy required for one to three people, and it makes your home environmentally friendly as well.
7 kW systems are large enough to meet the energy needs of larger-than-average homes. They can also meet the energy needs of average-sized homes with higher-than-average energy usage, or when combined with battery backup, may be able to support small to average-sized homes nearly full time.
Home Load Calculation
The regular load of a home is generally approx. 300W at all times whereas the maximum load of a home is 2200W. A homeowner never runs all loads at the same time. If he installs a 3kW solar system, he can run up to 2.5kW load at the same time.
Whole House: Starting at about 12,000 watts, these generators can generally keep a home running without missing a beat. You'll be able to run lights, fans, TVs, refrigerators, computers, space heaters and pretty much anything else you plug into an outlet.
Its starting watts will vary depending on the brand and model of each generator, but based on our experience the range is somewhere between 8000 – 9500 surge watts. Just don't expect to run your whole house on this machine simultaneously as this will require a lot more power than any 7500 watt generator provides.
Can I power my house with a 10000 watt generator?
In layman's terms, a 10000 watt generator can run all household appliances, power tools, RV & camping appliances, including: Small window AC unit – 1,200 watts. Fridge with a freezer – 700 watts.
As a general rule, the generator should be around 2 times the size of the inverter's continuous output. For example, a 4,000-watt inverter should be paired with an 8,000-watt generator. 8kW would make sense as a minimum generator size to power the loads and have enough power to charge the battery bank as well.
Running a generator full time means that replacement may happen every three months, but using a generator may be a necessity. Houses constructed in remote areas can have problems getting access to electrical power. Installing a generator capable of powering a whole house may be the answer to your needs.
At 12,000 starting watts and 9500 running watts, this unit can handle it all in an outage – lights, refrigerator, modem/router, security system, window AC, furnace blower, TV, computer, phone charger and more.
With 15,000 watts of power, the XP15000EH Dual Fuel generator will keep your entire home running during a storm or power outage.
