The generator is electromechanical equipment that generates electricity from the fuel poured inside it. Conventional generators work by burning fuel to generate electricity, but in recent years one more category of generators has come to light, which is the Inverter generators.
The inverter generators produce electricity which is extremely clean compared to electricity generated by conventional generators. This is due to their internal working mechanism, which gives these generators the name ‘Inverter generator’.
They can control their engine speed which gives them more quiet and efficient operation. Due to this they also have smaller fuel tanks which makes them more portable. However, they cannot supply as much power as conventional generators due to the small fuel tank.
The inverter generators are eco-friendly because they are EPA compliant and meet all the guidelines set by different regulatory bodies.
How Does an Inverter Generator Work?
The first inverter generator was developed and introduced by Honda; it looked the same as conventional generators but was smaller, lightweight, efficient, and quiet in operation.
The inverter generators use the same working mechanism as conventional generators do up to some point. Inverter generators also feature an engine that works on fossil fuel, and a single-phase AC electricity is generated, that AC electricity is converted into DC by a converter.
Now, this DC power is converted back to the AC power as per the connected load with the use of an inverter, that’s why the name inverter generators. This AC energy will be very clean with a much less THD rating.
The control of the output voltage and frequency is done by the microprocessor, which means that the engine won’t have to run at a constant speed (3600 RPM). This electronic control of the output power is the reason behind all the advantages the Inverter generator offers.
Inverter Generator vs Conventional Generator: Which One Should You Buy?
Whether it is an inverter generator or a conventional generator both of them have some advantages and disadvantages over each other. So, lets’ go over it and see for yourself which one suits your needs best.
The main and the most important difference between these two generators is the quality of the electricity generated. The electricity generated at the output terminal of a conventional generator will not be as clean as the electricity generated from the inverter generator.
The clean electricity is what makes the inverter generators so unique. That’s why you can directly connect the sensitive electronic equipment to the inverter generator, while you can’t do that with conventional generators. Besides, most of the other appliances in the home can survive the power of the conventional generator.
Power generation, that’s the domain where the conventional generator beats the inverter generators, is due to several factors. Conventional generators provide more power than the inverter generator.
Inverter generators don’t always run at the full capacity, the speed of the engine is controlled by the connected load at the terminal which makes it more fuel-efficient and very quiet compared to conventional generators that always run at a full speed. Because of this, they need more fuel than the inverter generators, which is why they have larger fuel tanks and it makes them bulkier.
Due to fuel efficiency, the inverter generators will need small fuel tanks which is one of the reasons for the less power output of the inverter generators.
If we talk about the price point, then the conventional generators are cheaper than the inverter generators. The reason behind the high price of the inverter generators is their new technology which offers benefits like quiet operation, high fuel efficiency, and very clean power generation.
If you don’t have a large power requirement and if the price isn’t the concern then go with the inverter generator, for more powerful capabilities and lower price point go for the conventional generators.
Key Features of Inverter Generator
What is it that makes these inverter generators stand out? The answer is its unique features, which we have discussed below.
Very Quiet Operation
For a recreational purpose or home use, the most annoying thing would be the sound of those open frame generators that keep running for hours.
While on the other hand, the inverter generators offer a much quieter performance. If we go into the specific, then if you get one of the best inverter generators, the noise level will stay between 50 to 60 dB. To put the number in context, this noise is comparable to the noise when two adults have a friendly chat.
As the power output increases, the noise from the inverter generators is bound to increase but it stays below a safe threshold of 65 dB.
High Fuel Efficiency
The working technology of inverter generators makes them highly fuel-efficient.
The speed of the engine will not be constant as conventional generators, it changes with the change in the load, if the load decreases the engine speed decreases and vice versa.
If the generator works at a constant speed, it will consume more fuel, but if it runs at low speed when the power requirement is less, then the amount of fuel consumed will be less. The inbuilt microprocessor inside the generator monitors the load and decides the engine’s speed, which will consume fuel that will be enough to supply the load at the terminals.
The main reason for which the inverter generators are known is their ability to generate very clean electricity that can directly be used to power modern electronics like the laptop, mobile, and TVs.
This clean energy is possible to generate because of the inverter stage in its working mechanism. The inverter circuit in the last stage makes sure that the generated power has as minimum THD as possible. THD is used to represent the cleanliness of electricity. If it is high, then the power is not clean, and if it is low, then the output power is clean and consists of a pure sine wave instead of a modified sine wave.
The high fuel efficiency of the inverter generator means it will need less fuel to generate the same power as the conventional generator does. Due to less fuel requirement, the size of the fuel tank will reduce. The small size tank means less weight and compact size of the unit, making the inverter generators very portable and easy to carry for picnics or campsite.
To decide on an inverter generator model, you will need to consider a few things, so you don’t regret it after buying. This will ensure that you don’t make the wrong choice.
First, Understand why you need an inverter generator in the first place. Do you want the generator to during outdoor trips or picnics or you want to power your house in case of an outage? Will you be moving it from one place to another place much often or will it sit tight in one place?
When you identify your needs, you can calculate the power you will need for different things. When you know what size generator you need, you can narrow down your list of inverter generators.
Second, Now it’s time to decide what kind of generator you want; is it compact, or is it small? The small generators supply electricity ranging from 800 to 1,000 watts. With that power, you can run one or two appliances no more.
On the other hand, the small generators offer a little more power output, which is 1,600 to 2,000 watts, sufficient enough to power up a couple of appliances.
To run more appliances you may want to go for medium or large size generators.
Can I plug my Portable Inverter Generator into my household wiring?
Yes, you can but with the use of a proper transfer switch. If you connect the generator to your house without a transfer switch, then it may even turn out to be deadly for you as well as for others.
Sometimes the reason behind the power cut is because someone is working on the power lines that’s why they are unenergized, but if you connect the generator to the house directly then it may feed the power to the main lines and can electrocute the person working. The reverse can also happen if the power comes back and the generator is connected, then the house appliances or the generator or both will get damaged.
Can an Inverter Generator burn me or explode?
Yes, it is possible. After the operation of the generator, if you overfill the oil tank, then it is possible that it will overflow over the engine and may result in fire or explosion. So never fill the tank of a portable inverter generator full; always have some space so that fuel can expand.
Also, don’t pour fuel when the generator is in operation. Before pouring the fuel, make sure that the engine is cooled down. Many parts of the generator will be hot after the operation, so stay away from them.
What are the proper cords I should use for my Inverter Generator?
You must use the proper cables which are rated for outdoor use, so it doesn’t get damaged easily. Also, make sure that the wire used has an adequate gauge so that it doesn’t get overloaded. The overloaded cables can be dangerous, and they can create fire or damage the equipment.
It will be in your best interest if you don’t use the wires which have exposed wires or the one which has worn out shielding.
Can I use my Portable Inverter Generator indoors?
The generators use fossil fuel to generate electricity. Due to the burning of that fossil fuel, the generator emits exhaust, which contains carbon monoxide, a deadly poisonous gas that is odorless and colorless, which means you can’t predict its presence in the room.
That’s why it is recommended that you don’t run the generator in the enclosed places. Always use them in the outdoor areas where sufficient ventilation is possible to avoid accumulation.
Still, if you have to install the generator indoors, we suggest that you install the battery-operated CO2 detectors indoors.
