Inverter generators have become a popular choice for portable power, offering a cleaner and quieter alternative to traditional generators. But what exactly is an inverter generator, and how do you choose the right size for your needs? Understanding the different ratings and sizes available is crucial to making an informed decision. Inverter generators are categorized based on their wattage output, which directly relates to their size and application. Consumer Reports breaks down these ratings into four helpful groups to guide consumers in selecting the best inverter generator.
Different Sizes of Inverter Generators
Choosing the right size inverter generator depends largely on your power requirements and portability needs. From powering essential home circuits during an outage to providing electricity for a weekend camping trip, there’s an inverter generator size designed for the task. Here’s a breakdown of the common categories:
Large Inverter Generators
Large inverter generators are the powerhouses of the group, typically weighing between 150 and 300 pounds, often including wheels for mobility. These robust models generate 5,000 watts or more, making them capable of powering significant portions of your home. A key feature of the largest inverter generators is their 220v outlets. These allow for a direct connection to your home’s electrical panel via a transfer switch. A transfer switch is a highly recommended safety device that allows the generator to safely power pre-selected circuits in your home, eliminating the need for numerous extension cords and directly powering lights, refrigerators, and other essential appliances. While their size makes them unsuitable for activities like camping or tailgating, their power capacity is ideal for substantial backup power at home.
Midsized Inverter Generators
Midsized inverter generators strike a balance between power and portability. Weighing 80 pounds or more, some models include wheels to aid in movement. These generators produce between 2,500 and 5,000 watts, suitable for a range of applications. However, unlike their larger counterparts, midsized inverter generators lack 220v connections, preventing direct connection to a home’s electrical panel with a transfer switch. This means they are not suitable for powering high-demand appliances like water heaters or well pumps through a transfer switch. Instead, appliances and electronics must be plugged directly into the generator. This size is particularly well-suited for recreational use, such as tailgating events or powering recreational vehicles (RVs). They provide ample power for plug-in devices like microwaves and toasters while remaining manageable enough to transport and position safely away from vehicles or RVs.
Small Recreational Inverter Generators
Stepping down in size, small recreational inverter generators offer a more portable power solution. These models typically generate between 1,500 and 2,500 watts. This wattage is sufficient for basic backup power, capable of running a refrigerator, some lighting, and charging phones. However, their power output is limited for more demanding needs. Similar to midsized models, small recreational inverter generators cannot be connected to a circuit breaker panel or power hard-wired devices without standard plugs. Many models in this category prioritize user-friendliness, often including features like fuel-level indicators, and some are equipped with wheels for easier transport. Weighing between 50 and 60 pounds, they are designed to be carried comfortably with one hand, enhancing their portability for various applications.
Compact Inverter Generators
Compact inverter generators represent the most portable and lightweight option. These units produce around 1,000 watts, enough for light-duty applications like powering a couple of small appliances during tailgating or camping trips. Typically lacking convenience features like fuel gauges or standard wheels to minimize size and weight, compact inverter generators prioritize portability above all else. Weighing between 30 and 40 pounds, they are designed for easy, one-handed carrying, making them ideal for situations where portability is paramount. Despite their small size, it’s crucial to remember that even compact inverter generators produce carbon monoxide. Therefore, safe operation outdoors and away from enclosed spaces is essential, and considering models with CO safety technology is highly recommended.
Conclusion
Understanding the different sizes and power ratings of inverter generators is key to selecting the right model for your specific needs. Whether you require significant backup power for your home, a reliable source for your RV, or a lightweight option for camping, inverter generators offer a range of sizes to meet diverse requirements. Regardless of the size you choose, always prioritize safety, particularly concerning carbon monoxide, and ensure you operate your inverter generator in a well-ventilated outdoor area.
