What Size Generator Do I Need for My House?

When sizing generator for home use, you should search for a product that will meet the power needs in your house. By opting for a generator that will match the power needs in your house, you will have minimised the amount of fuel that your generator will require to run.

You will have to consider the power output of the generator. In a common home setting, a standby generator may give you up to 2,000-4,000 watts power output. From this standby generator, your refrigerator may require 700W, a laptop will require 200W, a smartphone charger will need 20W, a security system will require 100W, and 5-10 light bulbs will need 250W.

What size generator to run a house will also be determined by the frequency of power outages in your location. If you experience prolonged power outages, then you will need a generator tailored to the conditions in that area. If the outages in your area are mostly prolonged by severe weather like storms and blizzards, then you will need a standby, portable or larger inverter generator.

Many times, the outages are controlled quickly, and you may not want a standby generator that is overly expensive. If this is the situation in your home town, you should consider buying a large inverter or portable generator. You will have to keep the large inverter or portable generator in a garage during the outage and install a transfer switch. By choosing the right type of generator, you will be able to light your whole household reliably in case of a power outage.

A standby, portable or larger inverter generators can connect directly to your home’s circuit breaker panel. These generators will also allow you to control and run appliances that are hardwired like air conditioners, central heat systems, well pumps, water heaters, and electric ranges. If you choose to go for these types of generators to help in power outages, make sure you hire a licensed electrician to install a transfer switch at your breaker box.

If you rarely lose power for long periods, then there is no need to purchase a large generator. Instead, you should go for mid-sized and recreational inverter generators. Mid-sized inverter generators have enough power to run a window A/C, space heater, or a fridge. Recreational generators are portable and compact enough to fit in the back of a pickup. A recreational generator will be able to power a TV and an electric cooker.


The Generator’s Wattage

When deciding what size generator for house, it is also important to consider the wattage. For this purpose, all you will need to do is simply add up the wattage of everything you want to power during an outage. While undertaking this process, you should keep in mind that some appliances like pumps, air conditioners, and refrigerators increase their wattage as they run. The surge watts can affect your calculations significantly. To calculate the power consumed by such appliances, you will need to hire the services of a licensed electrician.
