    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.

    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 Choose A Solar Generator For A 2000 Sq. Ft. House?
