Pros and Cons of Inverter Generators

Pros and Cons of Inverter Generators

The new Inverter Generators are designed to produce more AC electrical energy per engine rotation. Raw electricity from this unit is transformed into DC power. An electronic inverter module turns the DC power into the standard 120 volt, 60 HZ AC power.

Inverter Generators produce electricity that is safer for sensitive electronic devices such as cell phones and laptops.

Pros of an Inverter Generator

Power outlet of high quality

Inverter generators are capable of producing power similar to the reliable power you get from your outlets at home.

Smaller and lighter in size

Inverter technology integrates parts from the engine and the generator. This technological integration makes the generator lighter in weight and smaller.

Fuel efficiency is now higher

The generator’s engine automatically adjusts the engine speed. When the engine doesn’t have to run at full speed constantly, the generator reduces fuel consumption by 40% and reduces exhaust emissions.

Operation is quieter

The newer engines are not continuously running at full speed creating a quieter engine.

Double your power capacity with parallel capability

Parallel capability makes using two smaller, lighter generators capable of doing the

Fewer emissions

Consumer Reports explain these generators have a more sophisticated exhaust system which results in less carbon monoxide poisoning emissions. The unit is much safer for you and your family.

Cons of an Inverter Generator


Inverter Generators are 2100% more expensive than a similarly rated conventional generator. The alternator that converts DC to AC systems is much more expensive than a simple Alternator on a Conventional Generator.

Inverter generators are more complicated

A conventional generator is simple in design.  The motor usually runs at 3600 RPM and once started continues to run. The alternator is not able to adjust the rpm of the motor if demand requires the change. The motor senses the change in load and tries to maintain it automatically at the standard rpm.

Expensive repairs

The Inverter Generator is capable of measuring the load and adjusts the rpm as the load changes. This service is normally electronically controlled. When it does not work properly, you will have difficulty finding someone to service it. You will need to use an authorized service center for your specific machine.

Inverter generators are not available in large sizes

These types of outdoor power equipment are not available for higher loads. For example, the largest Honda Inverter Generator is 6500 watts and has an MSRP of $4500. The largest Yamaha Inverter Generator is 6300 Watts and MSRP of $3700.

Generator Types to Consider

People usually buy generators before or after a major storm – without a plan for using it. To help you decide which generator you require, know your power priorities. The amount of power a generator delivers determines how many lights and appliances you can run at one time.

Generators come in three varieties. It’s worth knowing about them all in case an inverter generator isn’t right for you:

  • Home category generators
  • Portable generators
