Now more than ever, full-house generators have become essential equipment for families, especially during power outages. Whether you’re living in areas where power failures frequently occur or just looking for a backup power source in case of emergencies, purchasing an appropriately sized generator is crucial, particularly to run your AC. A generator that can run a full house with AC is often dependent on a number of factors, including the size of your home, your energy consumption, the wattage your AC requires, and more. Let us discuss in-depth the size of the generator one needs to run a full house with AC.
What Is A Full House Generator?
A full-house generator, also known as a standby generator, is a backup power source that powers up automatically in case of a power outage or electric failure. The generator’s operations begin automatically, typically within ten seconds of a power failure. Fortunately, full-house generators have a high capacity, and they can power all of your home appliances, making them an ideal choice for long-term power outages.
Factors That Determine The Size Of Generator Needed To Run A Full House With AC
Numerous factors determine the size of generator one may need to run a full house with AC. Some of these factors include:
Size Of Your Home
The size of your home plays an essential role in determining the generator size you need. A larger home requires a more powerful generator. The more square footage you have, the more appliances and electronics you’ll need to power up to keep your home running comfortably.
AC Wattage Requirements
Your AC wattage needs determine the number of watts your air conditioning unit needs to run effectively. To determine the AC wattage, check your AC owner’s manual or contact your AC manufacturer to find out the AC wattage you require.
Energy Consumption
To determine your energy consumption, you need to assess the appliances in your home which will run on the generator. Assessing your energy consumption will help you determine the amount of power you need to sustain your home during a power outage.
Peak Demand Hours
Peak demand hours occur when most people are using electricity and coincide with the hottest times of the day. During peak hours, the electricity is most expensive, and power grids tend to be more stressed. A generator that can handle peak demand hours will often need to be more powerful.
What Size Generator Do You Need For Your Full House With AC?
The size of your generator for your full house depends on the above factors. However, as a general rule of thumb, generators can have anywhere from 22 kilowatts (kW) to over 150 kW.
To determine the size of the generator you need for your full house requires some calculations. However, you can estimate the required generator size using some specific formulas based on the above-discussed factors. Here’s a quick overview of the process of determining the generator size required:
- Compute the total wattage of your nominated appliances and devices to be powered.
- Add the AC wattage requirements of your air conditioning unit.
- Determine the starting wattage for each nominated appliance or device.
- Calculate the total starting wattage and use it as a guide to select a generator.
- In general, one needs a generator between 20 kW to 40 kW to power a full house with AC.
Conclusion
The size of the generator you need to run a full house with AC will depend on several factors. However, the best way to determine the generator size required is to start by computing the power needs of each of your devices and appliances. This way, you will be able to assess the total energy consumption of your house and make an appropriate decision when selecting a generator size. With the right generator size, you can guarantee your family’s comfort during power outages.
