The best inverter generators provide you clean, reliable power for your RV, camping trip, or any other activity that requires portable electricity. Inverter generators are quieter and more fuel-efficient than traditional generators and produce a smoother waveform of electricity, which is ideal for sensitive electronics such as computers, TVs, and sound equipment. However, with so many different inverter generators on the market, choosing the right one for your needs can be a daunting task. In this article, we will discuss the key factors to consider when choosing an inverter generator and review some of the best models available.
One of the most important things to consider when choosing an inverter generator is the wattage you need. Wattage is a measure of how much power a generator can produce, and it will determine how many appliances and devices you can run at once. To determine the wattage you need, add up the wattage of all the devices you plan on using simultaneously. It is also a good idea to add a buffer of 20-30% to account for any unexpected power needs. For example, if you plan on using a 1000-watt microwave, a 500-watt coffee maker, and a 200-watt TV, you will need an inverter generator with a minimum wattage of 1700 watts.
Another important consideration is the runtime. Runtime is the amount of time a generator can run on a single tank of fuel. Runtime will vary depending on the size of the fuel tank and the fuel consumption of the generator. If you need a generator that will run for long periods of time, you will need to choose a model with a large fuel tank and a low fuel consumption. Additionally, you should consider the noise level of the generator. Inverter generators are generally quieter than traditional generators, but some models are quieter than others. If you need a generator that will not disturb your peace or the peace of others, you should choose a model with a low noise level.
Choosing the Right Inverter Generator for Your Needs
Consider Your Power Requirements
Determining the appropriate inverter generator for your needs hinges on accurately assessing your power requirements. To ascertain this, tally the wattage ratings of the appliances and devices you intend to power simultaneously. Once you have this figure, add a buffer of 20-25% to account for surge loads and future expansion. This calculation will yield the minimum wattage capacity you require from your generator.

Understanding Inverter Generator Technology
How Inverter Generators Work
Unlike traditional generators that produce raw AC power, inverter generators use a more advanced process to deliver clean, stable electricity. The process involves three main steps:
- Power Generation: The generator’s engine converts fuel into mechanical energy, which is then used to spin a rotor and stator. As the rotor rotates, it creates an alternating current (AC) in the stator.
- AC to DC Conversion: The raw AC power generated in step one is converted into direct current (DC) using a rectifier. This process removes any fluctuations or inconsistencies in the AC waveform.
- DC to AC Inversion: The rectified DC power is then inverted back into AC power using an inverter module. This module simulates a sine wave, producing smooth, stable electricity that is comparable to the power supplied by the electrical grid.
Benefits of Inverter Generators
Inverter generators offer numerous advantages over traditional generators, making them ideal for a wide range of applications. Here are some key benefits:

Inverter generators are designed to operate at varying loads, adjusting their engine speed and power output as needed. This results in improved fuel efficiency compared to traditional generators, which run at a constant speed regardless of load.
Portability and Convenience
Inverter generators are typically smaller and lighter than traditional generators, making them easy to transport and store. They also feature user-friendly controls and often come equipped with convenience features such as LCD displays and remote start capabilities.
| Feature | Traditional Generator | Inverter Generator |
|---|---|---|
| Power Output | Raw AC, with fluctuations | Clean, stable AC with low harmonic distortion |
| Fuel Efficiency | Runs at constant speed | Adjusts engine speed to load, improving fuel consumption |
| Portability | Bulkier and heavier | Compact and lightweight |
| Noise Level | Louder, due to constant engine speed | Quieter, thanks to variable engine speed |
Power Output: Sizing Your Generator for Maximum Efficiency
Determining Your Power Needs
The primary factor in choosing an inverter generator is its power output, measured in watts. To determine your power requirements, make a list of the appliances and tools you plan to use simultaneously. Each appliance will have a wattage rating, which you can find on its label or in the manufacturer’s specifications.
Essential Appliances
* Refrigerator: 700-1,500 watts
* Freezer: 500-2,000 watts
* Microwave: 700-1,600 watts
* Lighting: 100-200 watts per circuit
Power Tools
* Circular saw: 1,500-2,200 watts
* Drill: 300-1,000 watts
* Impact wrench: 800-1,500 watts
Calculating Power Requirements
Once you have a list of appliances and tools, add up their wattage ratings to determine your total power requirement. Remember to include a 20-30% surge capacity for starting motors and handling temporary overloads.
For example, if you need to run the refrigerator (700W), freezer (1,000W), microwave (1,200W), and two power tools (2,000W), your total power requirement would be:
“`
700W + 1,000W + 1,200W + 2,000W = 4,900W
“`
Assuming a 25% surge capacity:
“`
4,900W x 1.25 = 6,125W
“`
Therefore, you would need an inverter generator with a power output of at least 6,125 watts.
