Brief Answer: The right generator size for a house depends on your total wattage needs. You will typically need around 3,000 - 3,500 watts for running only basic essentials at home. If you live in a larger home with an AC or multiple appliances, you may require 5000 watts or more.

When the power goes out, one question comes to mind almost instantly: What size generator do I actually need to keep my home running? The truth is, there is no one-size-fits-all answer. A small home that only needs to keep the lights and fridge on will have very different requirements compared to a larger household that relies on heating, cooling, or medical equipment. In order to choose the right size generator for your home, you can start by looking at your appliances and their wattage needs. 

Once you know how much power your home uses, you will have a clear idea of the right generator size for you. If you are considering a cleaner, quieter way to keep essential appliances powered for hours or even days, Jackery Solar Generators are reliable solutions. These home battery backup solutions can power essential appliances with ease, while also helping you cut down on monthly electricity costs. 

AI Takeaways 

  • A solar generator can power a house, but the capacity you need depends on whether you want to run just essentials like lights and a fridge or the whole home, including HVAC and heavy appliances.
  • A solar generator for a house is a battery backup solution that stores energy from solar panels and supplies electricity to appliances during power outages or periods of high demand.
  • You need a generator that matches your home’s total wattage needs, which is typically 3,000 to 5,000 watts for essentials, and 10,000 watts or more for whole-house coverage.
  • A generator size chart lists common household appliances with their wattage, so you can calculate the right generator size by adding up what you want to run.
  • Why do you need a solar generator for the home.

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 3000 - 5000-watt generator is enough to power most household needs, including AC, water heater, washer/dryer,  lights, and kitchen appliances. 

For a whole house, a generator with a capacity between 10,000 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 portable power system that uses solar panels to convert sunlight into electricity and portable power stations to store the generated power. Jackery Solar Generators can power essential appliances in your 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 powering household appliances such as refrigerators, ACs, and lights. 

While a solar generator can power a house, the capacity of a solar-powered generator will depend on the home size and the number of appliances you power 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.

What Size Solar Generator Do I Need: Based on How Many People Live in 

A typical small household with 2-3 people usually requires a generator of around 5,000 watts. On the other hand, larger families of 5 or more may need a 7,000-10,000-watt generator, depending on the appliances they want to power simultaneously. Here is what size generator is needed based on how many people live in the house:

Why Do You Need a Solar Generator For House?

Preparing your home with an efficient and reliable power source is becoming more than necessary. With power outages and blackouts becoming common, keeping a power backup solution for the home is ideal. Until recently, fossil fuel or gas generators were the go-to choices for people. But today, people realize the immense benefits of solar power generators. Some other advantages of solar generators include the following:

  • Reliable and Renewable Energy

Solar generators are a reliable and renewable energy source compared to other power alternatives. The solar panels arranged beneath the sun will store the solar energy and convert it into electrical energy. As no artificial elements are involved in energy production, it adds up to help you access natural and reliable power.

  • Safe to Use at Home

Advanced solar generators like Jackery products feature a first-rate lithium battery that houses two chips for dual protection. In addition, four core detectors ensure an appropriate amount of charge flows to and from the solar generator.

The in-built Battery Management System (BMS)™ protects the circuit, guaranteeing that the generator is safe to use at home.

  • 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. Once you know the answer to "what size generator do I need for my house," you can reduce the high electricity bills. Not only does solar energy help you cut down the high bills, but it also ensures that you cause no harm to the environment by producing toxic carbon emissions.

  • Easy to Use and No Maintenance

Unlike gas or fuel generators, solar generators are extremely easy to use and require no maintenance. You can dust off the solar generator with a clean cloth to ensure it runs efficiently. The press-and-play feature of Jackery Solar Generators provides that anyone can operate it with a single button press. In addition, it features a battery-level monitoring system and fault code indicators that make it user-friendly.

  • Quiet

Solar generators do not have any moving parts. That said, no noise is produced while the solar power station operates. The solar generator's cooling fan produces no more than 53 dB of sound. That's why solar generators can also be utilized during nighttime as it works silently to give access to clean power.

Before buying any generator, always ask what size generator to run a house. Once you know the answer, understand its features and make your purchase. For example, an essential home backup solution, such as the Jackery Solar Generator HomePower 3600 Plus, is easy to use and can help you power your core house appliances during blackouts.

For Stephanie Adkins in Florida, repeated blackouts during hurricane season once meant spoiled food, unsafe heat, and sleepless nights. With the Jackery Explorer 5000 Plus and a transfer switch, she now keeps her breathing machine, refrigerator, and lights running seamlessly, without the fumes or noise of gas generators.
