Inverter Generator Vs Standard Conventional Generator

This infographic shows a side-by-side comparison of a 2200-Watt inverter generator and a 7500-Watt conventional generator under no particular brand or model. Observe the huge differences in terms of fuel consumption within 15 hours of run time, the engine speed to run a 1000-Watt load, and the cost of fuel in most home applications.

Inverter Generators

What They Do and How They Work?

Inverter generators are smaller, lightweight, and much quieter generators. The inverter generators draw power from a DC source like solar panels or car battery, and convert it into AC power using electronic circuits. 

With advanced technology applied in designing inverter generators, they are considered to be the most innovative products. Inverter generators are your “to-go” electricity.

Here are some of the best features of portable inverter generators. 

  • Additional Features: The idle or low power feature allows an inverter generator to run at a lower level when not in demand. Most inverter generators would refer to this as the Eco Throttle System. This system enables the inverter generator to run efficiently at a lower load.
  • Noise: Often as low as 45 decibels and even at full load, inverter generators are still the quietest in the power generator industry. This makes them the first choice when it comes to home application usage or camping and tailgating where a conventional generator machine noise is unbearable. 
  • Size: On average, inverter generators are small and can be hand-carried. Their insulated parts and compact design makes them lightweight portable units.
  • Power: Inverters are a clean source of energy, which allows sensitive tools and equipment to be powered by them. Examples are mobile phones, computers, and laptops.
  • Parallel Capability: In order to produce twice the electricity output, identical inverter generators can be hooked to one to another with the use of cords.

Standard Conventional Generators

What They Do and How They Work?

Conventional generators are the most widely used units today. They can run either on diesel, gasoline, or propane. This engine basically provides power to a motor attached to an alternator in order to produce electricity. The electricity produced is typically 120 Volts AC. The size of these engines can range from anything as low as 500 Watts to up to thousands of kilowatts, allowing various appliances to run simultaneously. 

Best Features 

  • Fuel Capacity: Conventional generators often have larger fuel tanks compared to other generator types in the market. This feature allows for a longer run time and fewer efforts to refuel them.
  • Maximum Power Output: With engine sizes of up to 50 kilowatts, conventional generators provide you with a lot of options that are suitable for your extensive and specific needs.
  • Price: Regarding market competition, conventional generators typically have a lower initial cost to remain in the competitive landscape of generator industry. 

Choosing a Suitable Type of Generator

With all the makes and models of generators, as well as the types, choosing the right generator can become a tedious and quite an overwhelming task. Below are some factors you should consider prior to the purchase of a generator.

1. Fuel Efficiency

The level of fuel efficiency can be determined by engine speed and fuel tank size. Conventional generators typically have larger tanks, and inverters are slightly smaller. Since inverter generators run on shorter times, they provide you the chance to adjust engine speed to reduce fuel consumption and produce only the electricity needed. Conventional generators do not have the idle mode feature of inverter generators. 

2. Power Output

Your power needs will largely determine the type of generator suitable for your needs and application of use. Inverter models typically range between 1 kilowatts and 4 kilowatts, whereas conventional generators can range from 500 Watts up to more than 50 kilowatts.

3. Noise Level

For indoor-use generators, you must opt for a unit that produces the lowest possible decibel level. Inverters are designed for this specific use. The muffled sound of inverter generators is associated with the insulated body design. 

Conventional generators, on the other hand, typically run at a constant speed of 3600 RPMs. With this, they are significantly louder than inverter generators.

3. Convenience

More than anything else, the generator must provide ease of use and convenience. If you are looking for a portable power source, then an inverter is your best option. Inverters are usually small and compact in size, which makes them incredibly lightweight and can be hand-carried with ease. 

4. Price

Inverter generator units are said to cost more than conventional generators. The reason behind this is that fitting an efficient engine into a compact enclosed casing with a bunch of other additional features prompts the price of inverters to rise. With this, conventional generators become a common purchase for buyers that are looking for the superior power of convenience.


Although conventional generators and inverters are two of the most common equipment used in the power generation industry, they vary significantly in operation and in capacity. 

Conventional generators are complex and heavy-load devices with large tank capacities that use mechanical energy, like propane, gasoline and diesel, and convert them into electrical energy to produce electrical power. 

Inverters, on the other hand, are low-power devices that draw power from a fixed DC source and use a microprocessor system to convert the DC power into AC power. Inverters can be applied to modern household appliances such as lights, television, refrigerator, and so on. They have eco-throttle systems that allow for a much quieter operation.

To conclude, both generators supply power. Most conventional generators are used for establishments and buildings that do not require silent operation and demands for more power production. Whereas inverter generators are perfectly designed to be applied in residential homes. 

Your decision on whether to purchase a conventional or an inverter should heavily depend on your usage. If you are to transport the generator every now and then, then opt for an inverter. For fixed placement and if the noise level does not bother you, then a conventional generator can power several equipment and appliances simultaneously.
