How Inverter Generators Work

how inverter generators work

Inverter generators work by converting AC electrical current to DC, then inverting it back to AC to produce a cleaner wave of electricity. This can be useful if you are using a fuel cell or battery to generate power and need AC for equipment that operates on mains electricity. However, you should be aware of the disadvantages of using an inverter generator. If you do not have access to a utility grid, you may not be able to operate your equipment.

Reduced total harmonic distortion

A large advantage of using inverter generators is reduced total harmonic distortion (THD). THD is a percentage deviation of sine waves from the ideal condition. When power is delivered to a sensitive device, higher THD levels can cause damage. Fortunately, many inverter generators are designed to limit this distortion to below 1%.

The AC voltage supplied by a generator has a sinusoidal waveform. This means that it is very close to the ideal curve, represented by the math function sine, which is near zero. As a result, the current flows towards the edge of the wire. However, due to the presence of harmonics, this current does not add up to zero. Consequently, the current can flow through the neutral wire, which can lead to overheating.

Another harmonic phenomenon, voltage notching, can cause malfunctions in sensitive electronic devices. However, inverter generators are designed to produce lower THD than conventional generators.


When it comes to generators, inverter generators are a great option because they are quieter than regular generators, and produce cleaner electricity. They also tend to weigh less than traditional generators. Many of these units are also portable, making them perfect for boondockers and campers. Some models are equipped with wireless remote starts, which lets you start your generator with the push of a button.

Unlike standard generators, inverter generators have smaller motors and use sound dampening technology to reduce noise. They can also throttle when the load is low, reducing fuel consumption. Although inverter generators aren’t completely silent, their decibel levels are much lower than standard generators, and they’re also safer for sensitive technology.

Quieter inverter generators are ideal for emergency situations. The sound levels of traditional gen-sets typically increase as they age, and inverter generators reduce that risk.


Fuel-efficient inverter generators offer a number of benefits over conventional generators. For starters, they are more environmentally friendly. Their smaller fuel tanks and inverting technology allow them to run on either gasoline, propane, or natural gas. They can also be connected in parallel to increase their capacity.

Fuel-efficient inverter generators are also quieter than traditional generators. However, these models are still not designed for heavy commercial use. The maximum output is 6500 watts, so if you need more power, you should consider a trade or AVR model. A large variety of inverter generators are available, from small and lightweight units to large and heavy-duty models. To determine which model is right for you, consider how many devices you plan to plug into it.

Another feature of inverter generators is their ability to generate clean, smooth electricity. This is critical when using sensitive electronics. Fuel-efficient inverter generators can adjust the engine speed to match the load. As a result, they use less fuel and are more compact.

Less bulky

Conventional generators consist of a motor with an attached alternator. They are simple machines that are relatively easy to maintain and operate. They crank at a standard rpm, typically three thousand or four thousand, and do not require any complex controls or electronics. They also offer portability and quieter operation.

Inverter generators are available in a variety of shapes and sizes. Each model falls into a category based on their specific features. Because each category addresses a different problem, it’s important to know which category to purchase. Inverter generators typically range in power output from 1000 to four thousand watts.

The weight of an inverter generator is another important consideration. Although most inverter generators are marketed as portable, any model that weighs more than forty pounds is too bulky for most users to carry. Ideally, generators should be lightweight enough to be carried easily with one hand. Additionally, generators should have wheels.
