Understanding Your Power Requirements

Listing and Calculating the Power Needs of Your Appliances

To accurately determine the power needs of your appliances, start by creating a comprehensive list of all the devices you plan to run using the inverter generator.

For each appliance, note its wattage, which can typically be found on the label or in the user manual. Add up the wattage of all the devices to establish your total power requirement, ensuring you have a clear understanding of the inverter generator capacity you need to safely and efficiently power your equipment.

Determining Continuous and Surge Power Requirements

After establishing your total power requirement, it’s essential to account for the surge power needs of certain appliances.

Devices with electric motors, such as refrigerators, air conditioners, and power tools, often require a higher initial power surge to start, which is typically 2-3 times their continuous power rating.

By factoring in these surge power requirements, you can ensure that your chosen inverter generator can handle the peak power demands of your appliances without overloading or causing damage.

Sizing Your Inverter Generator Based on Your Power Needs

Sizing your inverter generator based on your power needs involves selecting a model with a capacity that meets or slightly exceeds your calculated requirements.

This ensures that the generator can comfortably handle the load without straining or overheating, ultimately leading to a longer lifespan and more reliable performance.

Additionally, properly sizing your inverter generator allows for greater fuel efficiency and prevents potential safety hazards, such as overloading and electrical fires.

Fuel Type and Efficiency

Inverter generators commonly run on gasoline, diesel, or propane, each with their own advantages and disadvantages in terms of fuel efficiency, availability, and emissions.

Understanding the pros and cons of each fuel type will help you make an informed decision about which inverter generator is best suited for your specific needs and preferences.


Gasoline is the most commonly used fuel for inverter generators, mainly due to its widespread availability and relatively low cost.

However, gasoline-powered generators typically have shorter runtimes and lower fuel efficiency compared to diesel or propane models.

Additionally, gasoline has a shorter shelf life and is more prone to degradation, which can negatively impact the performance of your generator.


Diesel-powered inverter generators offer better fuel efficiency and longer runtimes compared to gasoline models, making them ideal for extended use.

Diesel fuel is also more stable, with a longer shelf life, which reduces the risk of fuel-related issues.

However, diesel generators are generally more expensive upfront and can be louder and heavier than their gasoline or propane counterparts.


Propane-powered inverter generators are known for their clean-burning properties, producing fewer emissions than gasoline or diesel models.

Propane has an indefinite shelf life, making it an excellent choice for long-term storage and infrequent use.

However, propane generators usually have lower power output and can be less fuel-efficient than diesel models. Additionally, propane tanks add extra bulk to the overall setup, which may affect portability.

Portability and Size

One of the main advantages of inverter generators is their compact design and portability.

When selecting an inverter generator, consider the importance of portability for your specific needs and applications.

Will you be frequently transporting the generator, or will it remain stationary for most of its use? Assess the weight and dimensions of various inverter generator models to determine which one best suits your requirements.

Handles and Wheels

Some inverter generators come equipped with handles and wheels to facilitate transportation.

These features can be especially helpful if you plan to move your generator between locations frequently or if you have limited lifting capabilities.

Keep in mind that adding wheels and handles may increase the overall weight and size of the generator, so be sure to account for these factors when comparing models.

Noise Level

Inverter generators are known for their quiet operation, making them ideal for use in residential areas, campgrounds, and other noise-sensitive environments.

However, noise levels can vary between different models and brands, so it’s essential to compare the decibel (dB) ratings of various inverter generators to find the quietest option for your needs.

As a general rule, a difference of 10 dB corresponds to a perceived halving or doubling of the noise level.
