Generator or Inverter: Which is Better?

Due to their similar applications, power inverters and generators are frequently mixed up. Despite their similarities, the two machines operate on different principles and vary in terms of usage and carbon footprint. The purpose of this article is to provide a comprehensive comparison between power inverters and generators. Furthermore, we will also explore diverse scenarios in which one option may be better suited than the other.

What is a Power Inverter?

A power inverter is a gadget that transforms straight present (likewise called DC) into basic rotating present (AC). Inverters are utilized to run electric devices utilizing power produced by car or aquatic batteries, or sustainable resources such as photovoltaic panels or wind turbines. Straight present power is kept in batteries, while many home devices need AC power to run, therefore the requirement for an inverter to transform the power into a functional develop.


What is a Generator?

A conventional generator is any device capable of converting mechanical energy to electrical energy. Portable generators commonly used in households run on fuels such as diesel or propane. A diesel-driven motor (which runs at a constant speed of around 3000 rpm) converts the rotational energy into AC electricity.

This 120V AC power supply can be used to operate typical appliances. However, direct DC power is not available. In situations requiring long and reliable power supply, a generator might be a better choice than an inverter.

Generators do not require an additional battery supply. However, they tend to produce a lot of noise and emit fuel exhaust that is not environmentally friendly. Let us look at a comparison between inverters and generators in terms of size, weight, portability, efficiency, and noise levels.


Comparison between Inverters and Generators

Size and Portability: Both inverters and generators can be carried around, but inverters are usually more compact in size. Generators are bulkier and require a frame or wheels for installation. Therefore, if you need to power up for small tasks like hiking trips or camping nights, the inverter will be your go-to option.

Fuel Efficiency: Inverters are typically more efficient than generators and, due to the absence of a large fuel tank, are more compact in size. However, it is important to remember that inverters work in conjunction with a battery and do not generate power by themselves. Inverters are capable of running loads for about 10 hours, making them suitable for most small applications.

Noise Levels and Exhaust: The main advantage of inverters over generators is that they are quieter and produce less pollution. Traditional diesel generators produce a lot of noise due to the rotating AC generator. The combustion of fuel also emits polluted smoke. This exhaust is often considered dangerous by different health departments and requires special disposal methods. Inverters are more eco-friendly and do not require such disposal methods.

Electric power quality: Diesel generators are usually connected to loads without any power electronics processing unit in between. Therefore, due to the fluctuation of the engine speed, the generated power frequency can also flicker. Therefore, the electricity produced by the generator is not "clean." This may have a negative impact on many modern appliances that are sensitive to power spikes and dips. On the other hand, inverters have built-in capacitors that can smooth out the AC output produced. The electrical energy produced is very clean. A true sine wave inverter can produce a perfect sine wave, ensuring durability of your appliances. Modified sine wave inverters are more suitable for light applications, such as charging a phone.


Generator or inverter?

Portable power can be obtained from inverters which offer a more environmentally-friendly, lightweight and space-saving option. Although generators are still utilized in certain scenarios, there is a growing preference for inverters due to their straightforward operation, compactness, and user-friendly nature. Before choosing between a generator or an inverter, it is crucial to first identify your unique power requirements. Selecting a generator would be a practical decision if you find yourself running prolonged, laborious tasks regularly. For instance, if your business or workshop requires a backup power source during times of power failures.

Inverters have demonstrated their usefulness in various everyday scenarios, including furnishing backup power for households, furnishing portable power during hiking or camping excursions, and powering mobile vehicles like RVs, food trucks, and boats. In situations where noise levels or exhaust emissions need to be considered (such as in enclosed spaces like food truck kitchens), inverters are a better choice than traditional diesel generators.

Where to use a generator?

Commercial diesel generators are useful in situations where you must run heavy loads for a long time. In some cases, choosing a generator instead of an inverter is reasonable.

i) Your business premises experience power outages due to routine maintenance, but you need to keep your business running and operate some equipment.

ii) Your home experiences power outages for several days and you need emergency backup.

iii) Outdoor activities, such as weddings or receptions held in remote areas, where there is no reliable AC power source and heavy equipment such as instruments, sound systems, and speakers need to be used.


Where to use an inverter?

In other situations, where you need to provide portable clean power for reasonable loads within a reasonable time, inverters are a very convenient and environmentally friendly choice. Here are some preferred power inverter applications:

i) On a fishing trip when you need power on your boat to charge your phone, camera, and GPS.

ii) When driving an RV and you want to keep your coffee maker, microwave, radio, TV, and toaster running.

iii) In mobile kitchens and enclosed spaces, generator exhaust emissions are a problem.

In conclusion, we have discussed several differences and applications of generators and inverters in detail. We hope that once you have determined the power you need based on your unique user situation, you will be able to make wise decisions about the equipment you need.
