Determining Generator Size: An Explanation
Brief explanation on what generator size means
Generator size doesn’t refer to the physical size of the generator, but rather to the amount of electrical power (measured in watts) it can deliver continuously. It is crucial to comprehend that generator size typifies the maximum capacity the unit can provide. The size of a generator is directly defined by its power output capacity and is measured in kilowatts (KW) or watts, with each kilowatt equaling 1,000 watts.
In essence, the size of the generator reflects its ability to meet the power demand of the appliances and systems you want to be operational during a power outage. If you select a generator with a power output that is too small, it will not have the capacity to run all your necessary devices or systems, potentially leaving you in the dark or without essential appliances at a crucial time. On the other hand, choosing an excessively large generator will result in unnecessary expenditure and fuel consumption. That’s why understanding generator size is crucial when purchasing a suitable model for your home.
Factors affecting the size of the generator needed
Several factors can influence the size of the generator that will best meet your needs:
- Power requirements: The number of appliances and systems you want to keep operating during an outage determines your power needs.
- Size of your home: Larger homes generally use more power, so you’ll need a larger generator.
- Type of appliances: Some appliances require more power to start up (starting wattage) than to run (running wattage). For example, a refrigerator may need 800 watts to run but 1,200 watts to start.
- Medical or special equipment: If you have critical medical or special equipment that requires electricity, you may need a generator with more capacity.
- Future additions: If you plan to purchase more appliances in the future or expand your home, it’s wise to choose a generator with extra capacity to accommodate these changes.
Understanding these factors can guide you in choosing the most suitable generator for your conditions. Keep these points in mind when making any calculations or inquiries.
Ways to Calculate Generator Size
Discussing the manual calculation method
List of household appliances and their wattage
To manually calculate the generator size you need, create a list of all household appliances that you intend to power during an outage. Make sure to include everything from large appliances, such as refrigerators and air conditioners, to smaller items like a television, computers, or lights. The wattage requirement for each appliance can typically be found on a label affixed to the back of the appliance. Here are some average wattage values for common appliances:
- Refrigerator: Around 800 watts
- Freezer: Around 600 watts
- Washing machine: 900 – 1100 watts
- Dryer: 1800 – 5000 watts
- Dishwasher: 1200 – 2400 watts
- Air conditioner (10,000 BTU): 1500 watts
- Heater (10,000 BTU): 2500 watts
- Television: 100 – 200 watts
- Computer: 60 – 300 watts
- Light bulb: 60 watts per bulb
Remember that these are only average values and actual power consumption can vary depending on the exact model of your appliances. It is always recommended to use the specific wattage listed on your appliances. Also consider that appliances with motors, such as refrigerators and air conditioners, require more power to start up (also known as ‘starting wattage’) than they do to run. This should also factor into your calculations.
In the next subtopic, we will provide a step-by-step guide on how to sum up these wattages to calculate your total power needs.
Step-by-step walkthrough on computing total needs
Computing the total power needs manually might seem daunting at first, but with a clear understanding and the right method, it certainly gets easier. Here is a step-by-step guide:
Step 1: List down Every Important Appliance: Make a comprehensive list of all the significant appliances and systems in your house that you’d want the generator to power. This might include essentials like refrigeration, heating/cooling system, lights, or even sump pumps in certain cases.
Step 2: Identify the Wattage of Each Appliance: Every appliance has a distinct wattage needed for operation. You can typically find this information on the appliance itself, or its manual, or from online resources. For instance, a refrigerator might use about 700 running watts, whereas a standard light bulb could require 60 watts.
Step 3: Separate Running and Starting Watts: Note that you need to account for both running watts and starting watts (the extra burst of power to start the appliance) for certain devices. For instance, your refrigerator might generally require 700 running watts but might need up to 2200 starting watts.
Step 4: Add Up the Wattage: Now, sum up all the running watts of every appliance on your list you need to run concurrently. Then identify the highest additional starting watts needed by any single appliance.
Step 5: Determine Generator Size: Your total running wattage serves as a baseline for the size of generator required. The highest starting watt addition should also be within the generator’s surge allowance. If your total running wattage was 3700, for example, and the highest starting watt addition was 2200, a generator with a rated power of about 4000-4500 watts could handle this load.
Use this method carefully to understand your power needs and hence, the optimal generator size you will require. If your needs are complex, or you have special considerations, you might want to consult a professional for accurate numbers.
Discussing online calculator tools
Online calculator tools offer a significant convenience for those striving to determine the appropriate generator size. These tools can be easily found on the websites of many generator manufacturers, as well as on independent energy-focused platforms.
To use an online generator size calculator, users will typically be asked to enter information about their household appliances. Some calculators may provide a list of common appliances, allowing users to simply check off which ones are in their home, while others may require users to input the watts that each appliance needs. In some cases, users may also need to denote how many hours each day an appliance is in use to get a more accurate calculation of energy needs.
One of the great advantages of online calculators is that they can factor in additional information easily, like peak demand or surge watts. This is significant as certain appliances need extra power when they’re first turned on. A good calculator should incorporate this factor into the final recommendation.
Remember, while online calculators provide a generally accurate estimation, they should not substitute for professional advice. Consumers are always encouraged to consult with a certified electrician or generator supplier for the most accurate determination of their home’s power needs.
Typical Generator Sizes for Different Types of Homes
Small apartments and homes
Small apartments and homes typically have fewer appliances and smaller square footage, thus, their power requirements tend to be less. For these types of residences, a generator that falls within the 3000 to 5000 watts range may suffice. This size can power basic necessities like a refrigerator, basic lighting, microwave and small electronic devices such as television sets and computers.
An example of a generator suitable for these homes would be a 4000-watt unit which can provide emergency power for up to eight circuits. It’s compact, portable, and significantly more affordable than larger models. Moreover, it can comfortably support a home during short term power outages.
Keep in mind, these recommendations are for people who want emergency power for the basics.

Special Considerations in Choosing Generator Size
Highlighting the significance of a starting wattage
Starting wattage, also known as surge wattage, plays a pivotal role in determining the size of a generator for your home. It refers to the initial burst of energy that certain appliances require when they’re first switched on. They draw more power initially to start their motors, after which their consumption drops to a lower running wattage.
Items like air conditioning units, refrigerators, garage door openers, and sump pumps require high starting wattages, which often are much higher than their respective running wattages. For example, an air conditioner may have a running wattage of 1,500 watts but requires a starting wattage of up to 3,000 watts.
Neglecting starting wattages may cause the generator to overload when these appliances start up, potentially causing damage to both the generator and the appliances it’s powering. As such, both the regular running wattage and the starting wattage of all appliances should be factored in when determining the necessary generator size for your home. This ensures that your generator has sufficient capacity to handle the initial surge of power without problems.
Consideration for adding additional appliances in the future
When choosing a generator size, it’s crucial to factor in the potential addition of more appliances in the future. This is particularly relevant if you plan any home expansion or renovation, or if you envision adding more electrical devices or appliances down the line. Allocating extra watts for future needs will save you from the inconvenience and cost of upgrading your generator later on.
For instance, let’s say your current calculation for necessary wattage comes out to 7,000 watts. However, you know that you are planning to add an air conditioner and a powered tool shed in the next few years, both of which could add a significant load on your generator. Instead of purchasing a generator with just the capacity you need now, consider investing in a larger one to accommodate future power consumption.
Your approach can vary depending on your plans. If you foresee a considerable increase in power needs, it may be wise to go for a significantly larger generator. However, if the change is likely to be minimal, then a slightly larger generator could suffice.
Remember, an overloaded generator can lead to damage and may even pose a safety risk, so it’s better to have a bit of extra capacity than to fall short. Planning for the future is a wise step that can save you from additional expenses and hassle later on.
Discussing options for houses with medical or special equipment
Choosing the right generator size becomes even more crucial when considering houses with medical or special equipment that need continuous power supply. These could include devices like life support machines, oxygen machines, mobility devices, or research and lab equipment.
There are two main things that you need to determine. First, the kind of equipment that needs to be powered and second, the wattage that each of these devices consumes.
For instance, an oxygen concentrator device averages around 300-500 watts. More sophisticated medical devices, like a dialysis machine, need anywhere from 1000-1500 watts. On the other hand, refrigerators used to store medication may require around 600-800 watts.
Apart from the regular wattage consumption, it’s also essential to account for the starting wattage, which refers to the extra power that appliances need to start running.
For homes with these special requirements, it is heavily recommended to look into an automatic standby generator. These kick in automatically during power outages and can provide uninterrupted power for extended periods, ensuring the well-being of those dependent on medical equipment.
Remember, it is also crucial to have a discussion with a medical professional about the power requirements of the medical equipment you’re planning to run on a generator. In addition, consider discussing with a trained generator technician to fully understand your power needs.
