Before you visit http://gardeningandhome.com/best-inverter-generator-guide/ to help you purchase the right inverter generator for you, there are two things you need to know about them first.
#1: How do they work?
Inverter generators still include a mechanical engine which winds a magnet in copper, just like in standard generators. The difference is that inverter generators create high frequency, 3-phase electricity that goes through two steps in order to turn into regular AC to be used for home appliances.
What is the three-phase thingy you ask? It makes inverter generators, inverter generators. The energy in our houses, as well as the power that inverters produce, is single phase. That means it’s a single sine wave. However, you should know that some inverter generators use square wave or modified sine wave.
If a single phase has only one wave, then naturally, the three-phase power consists of three sine waves or three electrical signals that overlap one another. This allows inverters to supply more energy in a given amount of time compared to conventional generators. The voltage also never goes to zero, that’s because if one phase is declining, it’s going to be filled in by the summit of another phase. A lot of industrial motors are tailored to run on three-phase power, but they can’t be utilized for typical consumer applications.
Inverters convert the high frequency, 3-phase AC into DC using a solid state rectifier. Then the power goes into an established 60 Hz. full sine wave inverter. After the conversion, you can use it to provide power for your appliances.
Because three-phase electricity generates more power for every rotation, the engine of the inverter generator can be smaller. The speed of the engine isn’t critical too. If the load is changed, the engine can either idle down or power up to meet the requirements. And because the engine is small and it runs only at 3,600 rpm (rotations per minute), the inverter generator is quieter than a standard one.
#2: How much do they cost?
Because they’re quieter, more efficient, and more environment-friendly, they come with more expensive price tags. Inverter generators are worth at least twice the price of conventional ones. Some are even eight times more expensive! This is because the high technology used in the 3-phase system and the microprocessor-controlled rectifiers are costly. The higher the level of the power, the higher the price of the inverter generator. Still, without minding the price, we can’t deny that inverters are better at supplying power than standard units.
