A conventional generator might not be the best choice to run delicate appliances. You need an inverter generator as it produces clean energy thanks to the presence of an alternator.

Inverter generators convert AC electricity into DC electricity that’s safer and more reliable. Thanks to this clean energy output, an inverter generator can be used to power sensitive devices including medical appliances, mobile phones, and laptops.

There are many benefits of an inverter generator. It helps you save fuel, minimizes emissions, and also reduces noise. Thanks to these traits and the ability to convert AC into DC, this generator is a viable fit for both heavy and sensitive appliances.

Such generators are perfect for indoors and outdoors, hence you even carry one when you go out on camping or hunting trips.

There are many inverter generators on the market to choose from, however picking one can be quite difficult due to the huge variety of available options.

To make it easier for you, we have selected a few inverter generators that are perfect for all users. Let’s have a look:

Yamaha EF2000iSv2 is a gas powered smart inverter generator that caters to both indoor and outdoor needs. It is quiet in operation and thanks to the inverter technology, adjusts the engine speed according to the power requirements.

    How To Find The Best Inverter Generator

    Inverter generators are great as they are safe to use and offer some other benefits as well. However, they all claim to be the best inverter generators, hence you need to be careful when picking one.

    Let’s have a look at some of the features that will help you identify a suitable inverter generator for your needs:

    Factors To Look Into When Buying An Inverter Generator

    This is an important section. Go through all the headings to know what factors matter when you set out to buy an inverter generator.

    • Choosing The Right Power Inverter: You can get smaller generators that only product about 2000W of power or you can opt for bigger generators that can go as high as 10000W.The only thing you need to consider is the number of appliances you have to run and the power they need to operate.1000W inverter generators are good if you only want to run a fan, bulb, and small appliances. It can also charge laptops or phones but may not be able to run bigger appliances.For those, you will need a unit that can produce at least 2500W of power. Such units can run television sets too. However, for bigger appliances like air conditioners, you will need a generator that can produce about 3000W of continuous power.
    • Noise: It’s important to choose a generator with as little noise as possible. This is because loud generators can ruin the surroundings and also make it difficult to work or rest.You need to look at the decibel rating to understand how much noise a generator would make. Higher the decibel rating, louder a generator would be.If you are looking for extremely silent generators, go for ones that come under 50-70 decibels. It’s even better if the unit comes enclosed in a noise reducing frame and mufflers.Generators under 50 dB produce little to no noise. Anything above that can be troublesome. Remember that it will be hard to find a generator that’s completely silent. You can, however, take steps to reduce the noise.Never make the mistake of placing the generator on the ground as it can cause vibrations. Other than this, consider placing it at a distance so that the noise can be reduced.A distance of about 20 feet is said to be good as it does not only suppress the noise but also reduces the risk of health hazards.
    • Starting Technology: Go for a generator that is easy to start. The electric start system is the best as you will only need to press a button to get the general started.Some generators, however, only offer a manual start. They require pulling the cord to start the generator. This mechanism can be irritating and also lead to backache.
    • Safety Features: If you’re a beginner, pick a generator that comes equipped with meter gauges so that you can keep tabs on the status. Moreover, look for features such as low oil shutdown so that you can prevent the unit from shutting off due to low oil.It can be very risky to operate a generator when the oil is low. Hence, such features can come in handy.

    FAQ: 5 Questions About Inverter Generators

    #1 How can I know if it is an inverter generator?

    Ans. Most inverter generators will contain the letter “I” in the name. This I stands for ‘inverter’ and can help you identify an inverter generator. However, a more reliable technique is to look at the features.

    Honda EU2200i 2200-Watt 120-Volt Super Quiet Portable Inverter Generator, for example, contains the letter “i” in the name “EU2200i”.

    Since inverter generators are in demand, most sellers clearly mention it on the marketing material.

    #2 What are the benefits of inverter generators?

    Ans. The biggest benefit of inverter generators is the ability to charge sensitive appliances. These generators produce clean output, hence there is no risk of fluctuations and damage.

    #3 Which inverter generator should I buy?

    Ans. The right generator depends on your needs and requirements. .Yamaha EF2000iSv2, 1600 Running Watts/2000 Starting Watts, Gas Powered Portable Inverter, for example, can be a good pick if you want to run only a few appliances.

    Consider Honda 7000W Super Quiet Light Weight Inverter 120/240v Fuel Efficient Generator with iMonitor LCD if you want to run a high number of appliances or need a lot of power.

    #4 How often should I change the oil?

    Ans. While this changes from generator to generator and the manual is the best option to get the answer, you should ideally change oil every 100 hours of use.

    Only use the recommended oil and follow all the guidelines perfectly. Champion 4000-Watt RV Ready DH Series Open Frame Inverter with Quiet Technology comes with a detailed manual that answers all oil change related questions you may have.

    #5 What are the risk factors associated with using an inverter generator?

    Ans. Inverter generators like Briggs & Stratton 30675 Q6500 Inverter Generator are safe to use but you need to be careful about a few things.

    These generators, like most other generators, may produce harmful gases so make sure to keep distance. Also, follow all maintenance tips and get the generator serviced if you encounter problems.

    The Bottomline:

    These are some of the best inverter generators you can go for. Pick one that suits you the best.
