Generators are a great source of power when you are not connected to a grid. A generator will allow you to run your appliances and devices during a power outage. It also allows you to charge your phones and other electronics when you are camping.
Different Types Of Generators
Generators come in various types and sizes. Aside from knowing what an inverter generator is, you need to get the right generator that will satisfy your power requirements. Here are the different types of generators:
Home standby generator
Also known as a whole house generator, this type can keep all your home appliances running. It is expensive and takes up a lot of space, but it can power your entire home for several hours. It can be connected directly to your circuit board, and whole house generators will turn on automatically in times of emergency.
Portable generator
If you prefer a smaller generator, a portable generator is what you are looking for. Because it is small, you can easily move and carry portable generators. However, it does not have much power to keep all your home appliances running.
Inverter generator
What is an inverter generator? This type is very different from the standard generators. It automatically adjusts its engine speed depending on the electrical demands. Because it is not running at a constant speed, inverter generators are usually not noisy. It is more expensive than other generators, but it produces few emissions, easy to carry, and is easy to maintain.
Gasoline generator
It is the most popular type of generator. It is suitable to help run your lower-powered appliances, electronics, and tools. It is quieter than a diesel generator and cheaper to acquire. But you have to consider that over time, the cost of gas is more expensive.
Diesel generator
This generator runs more efficiently compared to the gasoline generator. It is cheaper to operate and has a longer lifespan. Since it is heavier in design, it is less portable.
Natural gas generator
This type of generator runs on natural gas. It produces lower emissions than gasoline and diesel. A natural gas generator is the most cost-effective type.
Solar generator
Solar generators run on renewable solar energy. You can run a solar generator indoors because there are no emissions. This type of generator is more expensive to purchase, but it requires low maintenance.
Solar generators have lower power output, and since they rely on renewable energy from the sun, they may not be reliable during an emergency.
Now that you already know the different types of generators. Let’s focus on what is an inverter generator and how it works.
What Is An Inverter Generator?
What is an inverter generator? An inverter generator is a newer type of portable generator. It is similar to conventional generators but with an electronic upgrade. It automatically adjusts its engine speed depending on the electrical demand. Since it is not running constantly, fuel consumption is significantly reduced as well as the noise level.
How Does An Inverter Generator Work
After learning what is an inverter generator, it is now time to learn how it works.
In simpler terms, an inverter generator works by converting the alternating current (AC) into direct current (DC) and then inverting it back to alternating current (AC) to create a cleaner power. Inverter generators improve the quality of electricity and allow you to run your appliances and devices without fear of damage.
Conventional generators produce “dirty” power. This power refers to the voltage spikes that can harm sensitive electronic devices. It has a high total harmonic distortion (THD), which means that if you plug in your device to a regular generator, the spikes in the voltage could cause operating errors.
Inverter generators eliminate this and produce “clean” power. It is done by inverting the electrical wave to allow for a consistent flow of electricity, avoiding voltage spikes or “dirty” power.
Inverter Generator Vs. Conventional Generator
Inverter generators are not completely different from other fuel-powered generators. They still follow the same concept, with some added features and modifications. Inverter generators and other conventional generators serve the same purpose – provide power when you are not connected to a regular power source.
Aside from learning what is an inverter generator, it is also important to know its similarities and differences from the other types of generators. Here’s how they differ in terms of storage, power output, weight, maintenance, and noise level.
| Features | Diesel Generator | Inverter Generator |
| Energy | It generates electricity through mechanical devices that convert diesel into electrical energy. | It converts AC to DC. It stores converted energy and reconverts energy to a more stable electrical wave. |
| Storage | It does not store energy. It generates electricity once it starts. There is a time lag between starting and receiving the power back. | The power is stored in the batteries and then reconverted to AC to run the appliances. No time interval between starting and receiving back the power. |
| Weight | It is usually heavy and bulky. It is still portable, but the convenience factor is not there. | It is usually portable and easy to move around. However, its portability is affected by the set of connected batteries. |
| Maintenance | The diesel generator needs dedicated maintenance (oil change, lubricant change, etc.). | They don’t require a lot of maintenance. Just check the water level and make sure the battery terminals are clean. |
| Noise Level | It produces more noise. | Due to how it operates, noise is very minimal. |
