What Size Generator to Run a House (with Chart)
Table of Contents

A generator that can provide between 3000 and 5000 watts would be enough to power essential appliances during power outages or blackouts. However, the exact size depends on the number of appliances you want to run simultaneously and the size of your home.

Sudden power outages due to natural calamities can cause a lot of inconveniences, especially when no power source is available. A solar generator is a highly versatile and convenient power source for homes.

Think of it as a solar power source that can charge all home appliances, from electric kettles to large refrigerators. However, different solar power station sizes are available on the market, making it challenging to make an informed choice.

Before investing money into one, you need to ask yourself, what size generator to run a house? In addition, you need to understand which appliances you need to power daily.

This article will help our readers figure out what solar generator size will suit their power needs, how to calculate it, and which solar power generator they should buy.

Can a Solar Generator Power a House?

Yes, a solar generator can power a house, but the size of the generator will vary depending on the household's energy consumption and the size of the house. A 5000 - 8000-watt generator is enough to power most household needs — AC, water heater, washer/dryer,  lights, and kitchen appliances. 

For a whole house, a generator with a capacity between 15,000 and 20,000 watts is highly recommended, which can typically power most household appliances including lights, refrigerator, freezer, and even a central air conditioner, though the exact size depends on your specific power needs and appliances you want to run simultaneously

What Is a Solar Generator For a House?

 A solar generator for a house is a device that uses solar panels to convert sunlight into electricity and portable power stations to store the generated power. Jackery Solar Generators can power a whole house and combine Jackery Portable Power Stations and Jackery SolarSaga Solar Panels. 

When sunlight hits the solar panels, it converts the solar energy into DC electricity. The pure sine wave inverter in the portable power station then converts DC to AC electricity, which is suitable for charging household appliances such as refrigerators, ACs, and lights.

Can a Solar Generator Power a House?

Yes, a solar generator can power a house. However, the capacity of a solar-powered generator will depend on the home size and the number of appliances you charge simultaneously. Here is the breakdown of solar generator size based on house type: 

  • Small Apartment/Studio: 3-5 kW 
  • Average 2-Bedroom House: 5-7.5 kW 
  • Large Family Home: 7.5-10 kW 
  • Luxury Home with High Appliance Usage: 10kW+ 

What Size Generator Do I Need For My House?

Determining the right generator size depends heavily on which appliances you need it for. You can use the power generated by the solar generator to recharge different appliances and electronics, which will determine which solar generator you should invest in.

What Size Solar Generator Do I Need: Based on Square Feet

The size of the solar generator you need will depend on your power requirements, including the appliances you want to run. The right solar generator also depends on how many kWh does a house use and the home size, and here is a simple breakdown, indicating how many kW generator is needed to run a house:

  • 1000 - 1500 sq ft home: A 5000 - 7500-watt generator is suitable 
  • 1500 - 2000 sq ft home: A 7500 - 15,000-watt generator is suitable 
  • 2000 - 3000 sq ft home: A 15,000 - 22,000-watt generator is suitable 
  • 3000 - 5000 sq ft home: A 22,000 - 32,000 watt generator is suitable 
  • Over 5000 sq ft home: A 32,000 - 36,000 watt generator is suitable 

For example, a 7,500-10,000 watts generator is needed for a 1200 sq ft house as it can charge most of the household during long-term power outages.

  • No Fumes, No Need to Use Fuel

Solar generators use solar energy rather than fuel to recharge and power home appliances. That said, no fumes are produced, guaranteeing clean energy at home. To charge the home appliances with a solar power generator, you need to connect the explorer with solar panels and let it recharge its battery.

  • Saves Money and the Environment

Monthly electricity bills can dread you. However, that's not the case when you have a solar generator at home.
