How To Determine The Sizes Of Generator To Run A 2000 Sqft House?
Understand Your Power Needs
First, list all the appliances and systems you plan to use. This includes your fridge, lights, and maybe air conditioning.
Write down what you can’t live without. Each item has two kinds of power needs: starting wattage and running wattage.
Calculate Total Wattage
For this part, you’ll need a calculator. Don’t worry; it’s simple math. Add up the running wattages of all items you listed.
Now, find the item with the highest starting wattage. Make this your peak power need.
Your total should be the running wattages plus the peak power need. You can also use this handy generator wattage calculator to make things even easier.
Check the Square Footage Factor
Your house size is crucial too. A bigger house often means more power needs.
But here’s the thing: your house’s square footage doesn’t always directly tell you the generator size.
Yet, it gives a ballpark range. For a 2000 sq ft house, you’re looking at a 5000 to 7500-watt generator for basic needs.
Learn about Types of Generators
Two main types of generators are out there: portable and standby. Portable generators are cheaper.
You have to start them manually. Standby generators are pricier.
They kick in automatically when the power goes out. Knowing the type can help you decide the size.
Read Generator Labels and Manuals
Manufacturers put a lot of info on labels and manuals. You’ll see a term called surge watts.
That’s another name for starting wattage. You’ll also see rated watts, which is the running wattage.
Always double-check these numbers against your calculations.
How To Find The Best Size Generator for A 2000 Sqft House?
Many generators are presently presumed to be suitable for specific housing sizes.
Keeping an eye out for the following aspects might make picking the right generator for you a breeze.
A Consistent Power Source
The generator must be capable of maintaining constant active and reactive power.
Alternating current (AC) is the most commonly used type, however, some generators can offer direct current (DC).
If your home’s primary energy source is renewables, you may want to consider adding batteries to store surplus electricity during periods when there isn’t much sunlight or wind.
Noise Level
Noise pollution is a serious concern for ordinary generators. When deciding on the size of your generator, keep the noise rating in decibels in mind.
The generator is calmer if the rating is lower. A generator that produces 80 decibels is as loud as your neighborhood’s main street, complete with automobile honks.
To protect your ears, look for a generator with a decibel level of 60 or less.

Availability of Fuel
It’s worth noting that certain versions can operate on several fuel types, which might make them a suitable choice if your home runs on numerous sources at different times, such as solar panels and oil tanks.
This refers to the sort of fuel that the generator will utilize.
Back-up generators require a constant supply of fuel to be operational, so you’ll want one that can run on anything from natural gas or propane tanks to diesel.

Generator Types For 2000 Sq Ft House
Portable Generators
Portable generators are great for quick use. You can move them around easily.
They usually run on gasoline. Most have a pull cord to start the engine. This type is perfect if you plan to use it for different activities.
For example, you can also take it camping or to a work site. They’re not just for home use.
The downside? You’ll have to start it manually when the power goes out.
Inverter Generators
Inverter generators are a type of portable generator. They are quieter and more efficient.
These are great for sensitive electronics like computers. The reason they’re better is they produce cleaner energy.
So, your gadgets are safer. You can even pair two smaller units to double the power.
That’s cool, right? But keep in mind, they are generally more expensive.
Standby Generators
A standby generator is a permanent solution. A professional installs it for you. When the power goes out, it turns on by itself.
That’s very convenient. They usually run on natural gas or propane. These types can power your whole house.
Yep, every light and appliance. You won’t even notice the power went out! But remember, they are costly. You’ll also need space in your yard for the unit.
Diesel Generators
Diesel generators are known for their longevity. They are often used in commercial settings.
You could use one for a 2000 sq ft house too. These are fuel-efficient. They can also produce a lot of power.
But they are noisy and emit fumes. So, it would help if you placed them far from your living areas.
Solar Generators
Solar generators don’t use fuel. They use the sun’s energy. During the day, they collect sunlight.
They store this energy in a battery. When you need power, the battery provides it. They are silent and eco-friendly. The drawback?
They can’t store a lot of power. So they’re not great for long outages.
Dual-Fuel Generators
Dual-fuel generators can run on two types of fuel. Usually, it’s gasoline and propane. You can switch between them.
This gives you options. If you run out of one fuel, you can use the other. These are flexible but tend to be more expensive.
