How do Inverter generators work?

Inverter generators use a three-step process to generate power. First, the engine spins an alternator to create AC electricity. This AC power is then converted to DC by the inverter’s rectifier. Finally, the inverter uses electronic circuits to convert the DC back into high-quality AC power with a pure sine wave output.

What is an inverter generator?

The inverter in an inverter generator produces a pure sine wave electrical output, which is cleaner and more stable than the power produced by a conventional generator. This makes inverter generators well-suited for powering sensitive electronics and appliances. Inverter generators are able to adjust their engine speed based on the power demand.

How much power does an inverter generator produce?

Midsized inverter generators weigh 80 pounds or more and may or may not come with wheels. They produce 2,500 to 5,000 watts, but you can’t connect them directly to your electrical panel with a transfer switch because they lack 220v connections. That means you can’t use them to power equipment such as a water heater or a well pump.

How does a car inverter work?

The engine runs and spins the alternator, which generates raw AC power. This AC power is then fed into the inverter. Inside the inverter, the AC is first converted to DC power using rectifiers.

Should you buy an inverter generator?

It all depends on how you plan to use it and, ultimately, your willingness to pay more for better performance. As with a traditional portable generator, an inverter generator can power your home appliances and electronics when the electricity goes out.

What makes a good inverter generator?

An inverter generator tends to deliver power that’s “cleaner,” with more consistent voltage, which is reflected in the power quality test in our ratings. All of the recommended models have earned our highest score for power quality, while some of the conventional generators that we recommend score slightly below that.
