If you can’t make heads or tails of what exactly is an inverter generator, no need to worry guys, you have landed on the safe page. So you might be wondering whether it is an inverter or a generator or both?
What is an Inverter Generator?
Okay, first of all, what actually do we mean by the term inverter? In simple words, an inverter is a device or an apparatus that converts a direct current into an alternate current. There you go! This is what an inverter generator does. Well, along with tons of other processes going on. But, you do get the idea, right?
What is the purpose of an inverter?
An inverter is an electronic device or we can say circuitry that changes the direct current into an alternate current. The overall power handling, frequency, input voltage, and output voltage depend on the design of the specific device.
The power is not produced by the inverter itself, instead, it is provided by the DC source.
In the common generators, each engine rotation produces one block wave of AC power. Around 10-12 years back, Honda introduced these new types of generators, which are more portable, quieter, lighter, and efficient as compared to the other conventional models.
The alternate current that you get in return is no longer in block waves but in sine waves. This is because an inverter module turns DC power back into standard 120-volt AC power. It gives you the option to invert the electricity back into more stable and constant power.
Basically, the key function or purpose is to produce more AC electrical energy per engine rotation but it’s not in the form that can be used directly. So, the raw electricity must be transferred into DC power. You get the direct current(DC) from a battery and the alternate current(AC) from the wall outlets.
How does an inverter generator work?
The inverter takes the raw power produced by the generator and with the help of a special microprocessor several processes take place:
Step 1: High voltage multiphase AC power is produced by the generator’s alternator.
Step 2: The AC power is converted to DC.
Step 3: Finally, the inverter converts DC power back to AC.
The inverter consists of a special microprocessor that controls the entire process as well as the speed of the engine. Moreover, the inverter cleans and smooths the power to make it more high quality.
What’s the difference between a generator and inverter?
In simple terms, an inverter is a device that converts direct current to alternating current. It is a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. The inverter itself doesn’t produce any power, in fact, the power is provided by the DC source.
The AC power is first converted to DC using a rectifier and then is stored within a rechargeable battery. For various household purposes, industries, and traction, the power required is AC, while the stored one is DC.
So, the main role of the inverter is to convert this DC to AC, hence, making the stored power usable.
An inverter needs electricity for charging and can supply only as much energy that is stored inside the battery. For the places with more power cuts and outages, the inverter might need the backup of generators. It acts as an auxiliary power source during outages.
On the other hand, the generator is a device that converts mechanical energy produced by the engine into electricity. It basically converts motive power into electrical power for use in an external circuit. An electric motor is responsible for the reverse conversion of electric energy into mechanical energy.
One thing you need to note is that the generator is an electromechanical device, whereas an inverter is a power electronics device. For household purposes, industries, and traction alternating current is required.
AC is generated using an alternator (AC generator) in power stations. This electricity is then transferred over a long distance to our homes, industries, etc.
Inverters are more efficient, clean, and reliable and do not cause noise or environmental pollution when compared to a generator, which can make a lot of noise.
A power source such as kerosene, diesel or petroleum is needed to run a generator, whereas, on the other hand, an inverter charges the battery with the electricity itself.
But, although generators can be noisy and bulky as compared to inverter generators, which are more portable and lightweight, they have high capacities and are your best friends if you require more power output.
Some of the other differences between an inverter and a generator are that a generator requires an effort to start. Whereas, an inverter starts on its own whenever the power is gone. However, portable generators can be used right out of the box, but inverters proper installation and wiring.
In conclusion, both of them have their specific features and come with various pros and cons. While generators can prove to be advantageous in places with long power cuts, inverters can be more convenient in places with short power cuts and camping, etc.
Typical uses of an inverter generator
An inverter generator instead of running full tilt all the time throttle the engine up and down to meet the required demand. They are generally popular for producing lower emissions and operating quietly than the old conventional generators.
An inverter generator can be used for multiple purposes, giving you the advantage of versatility. They generally have small size and hence are perfect for recreational activities or purposes like camping or on yachts, where you need a portable device which is easy to move around.
Some of the models are capable of parallel connections that can be used in cases where more power is needed, with the help of more than one generator to increase the total power or current output.
Moreover, they are well suited to power your house during outages and start automatically whenever there is a power cut.
What are the advantages of an inverter generator?
An inverter generator comes with many advantages as compared to a conventional generator. Over the years generators have been labeled as heavy, bulky, and loud electrical tools. But, the smaller, lightweight and quieter inverter generator with its innovative technology has been responsible to bring a change.
Older models of generators used to have power fluctuates, but this has been eliminated with the process of transforming the power from DC to AC in the case of inverter generators. Many manufacturers are selling such units in the market, which comes in different sizes and power capacity.
Inverter generators have engines that run at variable speeds depending on the amount of load. They can adjust the speed according to the power requirements. Whereas, the conventional generators operate with constant speed. This awesome feature in inverter generators allows them to be more fuel-efficient and makes them environment-friendly equipment.
Electrical output and parallel capability: An inverter generator has high electrical output and parallel capability. The technology used in an inverter generator allows it to produce enough power similar to as used in homes. You can pair it up with another identical unit to double the power.
Moreover, with the feature of power capability you can use two small and lightweight inverters instead of using just one bulky and big old traditional generator for various applications, both indoors and outdoors.
High fuel efficiency: The conventional generators run at a speed of 3600 rpm. On the other hand, an inverter generator can run at slower rpm while at the same time, also maintaining the power and frequency. It can automatically adjust its engine speed, to produce only that much of the power which is required or needed. Since the engine does not run at full speed constantly, an inverter can reduce fuel consumption by up to 40%.
Super Quiet operation: A good quality inverter generator is equipped with a sound absorption system including large-size sound mufflers to absorb the operating noise of the engine and can relax during a power cut.
Maintenance: In the case of conventional generators, the fuel is needed to be replaced every 200 hours of use. The carburetor will run dry if the generator is not used for more than 30 days. A lot of maintenance is required to get proper power output.
But you don’t have to worry much about special treatments or maintenance. Just the inspection of batteries once in a year will work fine.
Drawbacks of inverter generators
Although inverters are quite popular because of the awesome advantages they give you over conventional generators, but still, there are some drawbacks we might come across.
When it comes to power, an average size generator can produce around 4000 watts of power, while an inverter generator will produce around 2000- 4000 watts of power. Hence, the generators are more powerful for heavy-duty machinery and tools, than an average size inverter generator.
Although inverter generators don’t need much maintenance and are more reliable, they can not be repaired by any random technician who is not so experienced, because of their complex technology.
Since they are more sophisticated and advanced than standard gas generators, you will have to pay more, and thus, you might need to check your budget.
Drawbacks of conventional generators
One of the biggest drawbacks of traditional generators is that they are quite huge and bulky. Hence, you might have to face problems while moving these big bulky machines from one place to another, if they are without wheels.
They tend to waste a lot of fuel if not operated at full load for a long period of time and can pollute the environment if not used near its capacity.
Which inverter generator size to choose?
Inverter generators come in various shapes and sizes. So, to get a better understanding of which size to pick for your needs, we have divided it into three categories:
Large: Large-size inverter generators usually weigh around 250 pounds which is quite bulky to move around, but big enough to power your house. They can generate powers of up to 5000 watts and can be connected directly to your electrical panel with the help of a device called a transfer switch. If you need high power output, then we will recommend you to go for a large-size inverter generator.
Medium size: Medium-size inverter generators can weigh around 80 pounds or more, and may or may not come with wheels. They can generate power of 2500 to 4500 watts but don’t allow the direct connection to your electrical panel using a transfer switch.
Recreational: These can weigh around 50 to 60 pounds and are mainly designed to be carried with one hand. Most of the models can produce power of around 2000 watts and are portable for camping. But, one thing that you should be careful about is, they emit carbon monoxide, which can even kill you at higher concentrations, and therefore, should never be operated inside an enclosed space.
Features to consider before buying a portable inverter generator:
Inverter generators come in various designs and their variations can greatly affect things like, how easy they are to operate and maintain and also their price.
The weight and size of the inverter generator might differ depending upon the design and features included in it. If you are going for the heavy one, it would be convenient to look for the one that comes with a wheel kit or apparatus, so that moving it around could be easy.
Some models have a feature or control that allows you to switch from the automatic power-saving mode to power boost mode when there is a need for short surges of power.
Don’t forget to consider the noise levels, especially concerning how far the unit was placed from the sound meter and also how much load it was running.
Technology like Intelligauge is featured in some models that include a display that allows you to monitor the voltage output, hours of operation, and frequency. Moreover, there is also a sort of LED to make you aware of an overload.
Parallel cables are included in some units that allow you to connect more than one generator at the same time to double the power.
Finding the best portable inverter generator for yourself
The decision of which inverter generator to choose from depends on various factors including what are your specific needs and what type of design and features you would like to have in it.
An inverter generator gives you the freedom of movement since they are easier to move around and are best for recreational activities such as going camping, or tailgating parties and will serve you as an efficient, quiet and reliable source of power.
