What Size Generator Do I Need To Run A 2000 Sq. Ft. House?

If you're planning to get a generator for your home, the first step is to understand your power needs.

Generator Size = Wattage Consumption × Number of hours you use it

Watts (W) = Volts (V) × Amps (A)

You can find the wattage requirements labeled on the top of the appliance. Generally, you can find the device's starting, running, and surge watts that determine the generator size for home backup.

• Starting Watts: The maximum energy your appliance will consume while starting up is called starting watts.
• Surge Watts: The maximum watts a generator must supply for a short time to start heavy-duty devices, like sump pumps, refrigerators, etc.
• Running Watts: The maximum watts of energy the appliance requires to run for longer hours.
• Rated Watts:The maximum wattage a generator can produce for a longer time to run electric devices in a stable condition.

The below table recommends the solar generator size based on usage.

Why Should Size The Generator?

In order to find the answer to "what size generator to run a 2000 sq. ft. house," you'll need to understand how much electricity the generator can output.

It's no secret that sizing a home generator is of utmost importance to understand if you'll get an uninterrupted electricity supply. When sizing the generator, you need to focus on how many appliances you want to power and for how long.

If you buy a generator that is too big for your needs, you'll waste your money on overspending. Alternatively, purchasing a small generator means your energy demands won't be met efficiently.  

Sizing Up

If you have a flexible budget, you can select a generator with more AC output and storage capacity. Investing in a solar generator that exceeds current electricity demands ensures you can add appliances in the future.

Sizing Down

Unlike sizing up, sizing down is a cost-effective option that suits best if you use less electricity. Smaller generators are portable and easier to operate. However, one downside is that you won't be able to charge multiple heavy-duty appliances at once.

How To Determine What Size Generator Do I Need To Run A 2000 Sq. Ft. House?

Choosing the right size generator ensures your electricity needs are met appropriately, and it won't run dry when used for long hours. Multiple critical factors determine what size portable generator to run a 2000 sq. ft. house.

What Type Of Generator Do I Need?

The first and foremost thing you'll need to consider is the type of generator, i.e., gas, propane, solar, and inverter generators. Even though gas and propane generators are popular choices, they are being replaced with solar and battery-powered generators.

How Many Watts Does A 2000 Sq. Ft. House Uses?

The watts consumption of a 2000 sq. ft. house will depend on the usage and number of appliances, like microwaves, TVs, refrigerators, and air conditioners. While an average household consumes around 5-7kWh, you might need a solar generator of 12-15kWh to power heavy-duty devices.

The below table indicates the common household appliances with their starting and surge wattage.

How Much Generator Power Do I Need?

If you're wondering "what size generator to run a 2000 sq. ft. house," you'll need to determine the common appliances' starting and running watts.

The simple formula to calculate the generator wattage is adding all the running watts of the appliances you want to use and then adding the single highest starting watts in those items.

Once you've calculated the wattage, sum the total running watts and highest starting watts to calculate the total watts needed.

Note: This is a general example, and your electricity needs may vary depending on how many appliances you're using simultaneously.
