Portable Inverter Generator Buyer's Guide
Written by Dan GibsonIntroduction
A portable inverter generator is a great addition to any home or RV, that can provide you with a reliable source of power for a variety of purposes. Portable inverter generators are designed to be light and compact, making them easy to transport and store. They are also very quiet compared to traditional generators, making them ideal for use in campgrounds and other locations where noise is a concern. In addition, most models come with a variety of features and accessories, allowing you to customize your generator to suit your specific power needs. When selecting a portable inverter generator, there are a few important factors to consider in order to get the best value for your money.
Types of Portable Inverter Generators
There are two main types of portable inverter generators: open-frame and enclosed. Open-frame generators are designed to be lightweight and portable, making them perfect for camping trips and other outdoor activities. Enclosed generators are typically larger and heavier, but they offer more protection from the elements and provide more power output. Additionally, some models come with additional features such as electric start and remote control, so it’s important to consider which features you need before making a purchase.
Size and Power Output
The size and power output of your portable inverter generator will depend on what type of applications you are using it for. For most home and RV applications, a generator with a wattage of around 2,000-3,000 watts will be sufficient. For larger applications such as powering a large RV or a construction site, you will need a generator with a higher wattage. Additionally, it’s important to consider the size of the generator, as larger models will be bulkier and harder to transport.
Fuel Type
The type of fuel your portable inverter generator uses is also an important factor to consider. Most models will use either gasoline or propane, but there are also models that use diesel fuel. Each type of fuel has its own advantages and disadvantages, so you should consider your needs and budget when deciding on which fuel type to use.
Noise Level
Noise level is an important factor to consider when selecting a portable inverter generator. The noise level of a generator is measured in decibels, and the lower the decibel level, the quieter the generator will be. Most portable inverter generators range from 55-65 decibels, which is comparable to a normal conversation. If noise is a concern, look for a generator that has a lower decibel rating.
Price
Price is always an important factor when making any purchase, and portable inverter generators are no different. Prices can range from as little as $200 to several thousand dollars depending on the features and size of the generator. It’s important to consider your needs and budget when selecting a portable inverter generator, as the more features and higher wattage you need, the more expensive the generator will be. Additionally, it’s important to compare prices from different retailers to ensure you are getting the best value for your money.
