Frequently Asked Questions About Inverter Generators (FAQs)

How Does the Inverter Generator Work?

To explain how portable inverter generators work, we must understand the two aspects of the inverter generator; the engine, and the alternator.

The engine is the main thing that powers the generator, and it usually consumes gasoline or propane as fuel.

The alternator has two primary components, which are the rotor and the shaft.

The stator gets the power from the engine shaft as it turns the rotor. This process allows the generator to produce energy and helps in powering sensitive electronics, power tools, and much more.

When compared to a regular generator, the inverter generator works entirely differently.

First, the power produced by the alternator is sent directly to the rectifier.

Rectifier is a device that converts the power from the (AC Power) or the alternating current to the direct current or the (DC power).

Then, the energy from DC is inverted back to the AC power using the generator’s computer before being sent out to the control panel. This process is where the generator gets its name, “inverter generator.”

Generator vs Inverter: What Makes an Inverter Generator Different?

What makes the inverter generator so unique is that it works efficiently by managing its power output.

Although, as mentioned previously, the running power is controlled by the computer inside the generator, it produces power with low THD, which means clean power in layman terms.

Furthermore, the drop in power will also mean that the generator will work more quietly, making it a pleasant experience for the users.

This is a basic overview of how the inverter generator works. Still, many more aspects allow the inverter generator to work.

That being said, the brief overview should give you an idea of the mechanics of an inverter generator.
