Buyer’s Guide

Should I keep it at a distance from my house?

Considering how loud these models can get, besides, it emits carbon dioxide which is injurious to health. It is advised you keep the generator at a considerable distance between 15 – 20 feet away from your house.


Afraid someone might steal it outside your house? Then don’t. You can build an enclosure to keep it while it’s running.


What are the advantages of a portable inverter generator?

Fuel Efficiency

Most of the Inverter generator models are created with a special type of technology to adjust to the engine speed to produce only the amount of power needed.


Traditional generators run at 3600 RPM to produce 60 hertz of electricity. While portable inverters utilize throttling equipment to run at lesser RPMs maintaining the power at a stable frequency. In essence, this method significantly helps to reduce exhaust emissions and fuel consumption.



Portable generators are lighter and smaller than conventional models which makes them easier to transport. Compared to large models where transportation and installation pose a great disadvantage, portable models are a respite in such situations. As they as lighter, you can carry them in the back of your RV or Car without hassles.


Quiet Operation

In some parts of America, there is an acceptable standard of decibels allowed from an equipment. This restricts outright disturbance in quiet neighborhoods. Most inverters have their engine speed throttled reducing the noise created. Inverters also utilize dampening materials to reduce the impact of sound. For most parts, 60 decibels or less is generally accepted to be the maximum limit of sound that doesn’t cause noise pollution.


Parallel Capability

Some Inverter models allow you to connect as much as two models for double output. This is convenient especially when you need mobility & portability over large heavier generators. Yes, you can get more power by simply joining compatible generators together without sacrificing portability.

Frequently Asked Questions (FAQs)

What’s the Difference Between a Regular Generator and an Inverter Generator?

Conventional Generators

Regular or conventional generators utilize diesel, gasoline or propane to power a motor attached to an alternator to produce electricity. They normally run at 3600 rpm despite the power load, this leads to a significant reduction in fuel.

Inverter Generators

These Units are produced with a special kind of technology which converts AC to DC voltage then inverted to clean AC voltage. This enables it to maintain a constant flow of current to an electric appliance, thus reducing fuel consumption.


How Does the Inverter Work?

Inverters utilize the power produced by the generator which passes through some processes explained below.


The first step involves producing high voltage multi-phase AC power through the alternator. The AC (Alternating Current) is converted to DC (Direct Current).


The inverter follows some processes to convert the DC into AC, the result is a clean power that’s efficient and smooth. A microprocessor controls the speed of the engine as well as the process leading to a quiet & stable operation.


Are Inverter Generators Worth the Money?

Yes, Inverter generators are worth every cent you spend. They are quieter, portable, lighter than conventional generators. And what’s more? inverter generators offer carbon-less emission. If you are concerned about green house effect, then there’s no better way to show it than using inverter generators than portable generators which are louder and emit a lot of carbon emission into the atmosphere.
