Why Should You Invest in An Inverter Generator?

Best 3000 watt inverter generator

Whether you’re looking for a home power backup plan or a portable power source, there are numerous reasons why an inverter generator should be your best pick.

  • They are fuel-efficient

Inverter generators have proved to be more fuel-efficient when compared to conventional generators. Inverter technology enables inverter generators to adjust the engine depending on the load size, unlike a traditional generator whose running speed is constant. When the load is low, inverter generators will use less fuel because they run at a low rate; this contributes to fuel efficiency.

  • They produce clean power

The mode of power production in an inverter generator ensures that it delivers clean energy for your sensitive electronics. While inverter generators produce power with less than 3% THD ratings, conventional generators have a higher percentage. The pure power from inverter generators also lowers their emissions, and it is therefore friendly to the environment as well.

  • Low noise ratings

Inverter generators run on small engines and have a casing made from sound-dampening materials. These two physical features ensure inverter generators produce noise levels below 60 decibels. Additionally, the engine speed adjustments of inverter generators also reduce the engine sound, and the noise level is low when the unit has a low load. This is different from conventional generators, which run on big engine sizes and no sound dampening materials. Conventional generators produce more than 65 decibels noise levels.

  • They are portable

Most inverter generators are lightweight because of their small engine and fuel tank capacities than conventional generators. The presence of convenient carrying handles and wheelsets on these units enhances the portability of inverter generators. They also come in small sizes for easy storage.

  • Most inverter generators come with parallel capabilities

In situations where you need more power, you can connect two generators to achieve your power demands. If you were using a conventional generator, it would have necessitated you to buy a bigger unit because they are not parallel capable. Parallel connection is economical because you will only use the two units when you have more power demand.

Factor to Consider When Buying the Best 3000 Watt Inverter Generator

Inverter generators differ in properties, do not be surprised to find two generators from the same company differing in their properties. Some models are perfect for RVs, camping while others are for home backup plans. Here are vital factors to look at;

  • Control panel

Check out the number and types of outlets available on the inverter generator you are about to buy. Different inverter generators have different types of outlets for connecting various electrical equipment. If your interest is to get a home backup unit, find one with household outlets and a Transfer Switch ready for easy connection to your home’s breaker box.

In our review, the Yamaha EF3000iS inverter generator can be operated from 75 feet away with remote control, thanks to its remote control feature.

  • Portability

If you are looking for a portable power source for your outdoor activities such as RVing, tailgating, and a construction site, you need a portable 3000 watt inverter generator. It should be easy to carry, have wheels, and a good handle. However, if you are looking for a home power backup plan, portability may not be a big issue.

  • Guarantee period

A reliable 3000 watt inverter generator should have a considerable warranty period of at least two years. Such a generator has a better bargain because you are sure of free repair or replacement should it break down or malfunction during the warranty period. Inverter generators are costly investments; you need an assurance that the unit you are buying will serve you for an extended period.

Other common factors to consider are the size of the fuel tank and noise level. The bigger the fuel tank, the more runtime the inverter generator will offer. However, this will depend on the efficiency of the generator. Noisy generators can be a bother to you and your neighbors. There are places where noisy generators are not allowed. Do not ignore the rated noise on your generator of choice.
