Generators provide backup power during outages and help power your devices when you are off the grid. Despite the value they provide, generators have a reputation of being loud and distracting. Starting one may fuel noise complaints from disgruntled neighbors in a heavily populated area. These loud noises, however, are typical of older and conventional generators. Over the last few years, many different types have emerged with advanced features that offer functionality and convenience. If you prefer something that is quiet, lightweight, and offers clean and efficient energy, we can swear by inverter generators.
As mentioned, inverter generators don’t contribute to noise pollution. Almost all models come with sound dampeners allowing the generators to produce between 50-60 decibels of sound only. For context, the sound of an engine while inside a running car or conversations in a restaurant fall within this range. Inverters also consume less gas overall. This is because their internal systems are capable of adjusting electricity output depending on the requirement of the device plugged into them. This means that inverter generators can save up to 30-40% fuel.
Another factor one must consider when getting a generator is safety. CO emissions from regular generators may cause poisoning if they are run in enclosed spaces. An inverter generator mitigates this problem because of its efficiency and the fact that it produces fewer emissions.
On top of all that, you can take inverter generators anywhere. Their compact and lightweight design allows for easy transport and storage. This is especially helpful if you’re camping or going off the grid for a couple of days to unwind. While inverter generators can be more expensive than traditional ones due to their unique set of advantages, you will be getting the bang for the buck with every purchase. Since there are plenty of options to choose from, read through our inverter generator reviews to select the best one for your unique needs.

Buying Guide
Power
The more power a generator delivers the more electronic devices or appliances it can run at the same time. Some generators can support more than 10,000 watts for hours, but these are the cumbersome and loud types. Inverters, on the other hand, are focused on efficiency, quietness, and portability. However, this also means a slight sacrifice in their total power output. Most inverter generators only operate between 2000 to 4000 running watts. An easy fix to this issue involves linking two parallel-compatible generators to increase power. Almost all modern inverter generators in the market today are capable of the said parallel connection.
Noise Levels
Always consider the noise levels if you do not want to make enemies of your neighbours. Equipped with great noise reduction technology, inverter generators ensure quiet operation. They have built-in suppressors in enclosed casings to reduce noise levels. When buying, you should aim for inverters that promise around 50-60 decibels. Running inverter generators indoors or outdoors should not be a problem as most of their noise levels are low enough and blend quite well in the environment.
Safety
LED indicators are present in almost all inverter generators. They let you know important information that traditional generators may not provide. If oil is at minimum levels, low-oil shut off prevents engine damage. Some inverters are also equipped with CO sensors which detect carbon monoxide emissions and automatically shut their engines down if the surrounding area reaches hazardous levels of CO. Spark arrestors also give you peace of mind especially when using the generator in areas where the risk of fire is high.
Features
Inverter generators have increased in popularity in recent years. Helpful features include weather-protected panels for outdoor use, built-in wheels for easy transport and manoeuvrability, and different outlets depending on the electrical need.
Traditional generators consume more gas than needed, whereas inverter generators deliver the exact power a device or gadget requires, saving more fuel in the long run. Most generators come with an economy mode for enhanced fuel efficiency.
Price
Although inverter generators are generally pricier than their conventional counterparts, they are often worth the investment. You can use them indoors or outdoors and have longer lifespan than other types due to their built-in safety checks. Other types of generators do not compare in terms of fuel economy. Inverter generators can be as much as 50% more efficient! Combined with their power, high-tech features, and safety, they are the best types of generators if budget isn’t much of an issue for you.
FAQs
How loud are inverter generators?
Unlike conventional generators, most inverter generators have noise reducing features that allow them to operate between 50-60 decibels. For smaller inverters, the sound can be compared to a quiet office or library. For larger ones, the sound is similar to normal conversations. They are measured at an industry standard of at least seven meters away from the source ensuring legitimacy of values.
Can I use my generator indoors?
Carbon monoxide poisoning has been widely reported as a hazard associated with indoor generator use. As much as possible, generators should be used outdoors. It also helps to buy a generator with a built-in carbon monoxide detector so you can ensure CO levels are safe at all times.
How can I store my generator?
For short term storage, keep generators clean from any debris. For long term storage, filling the fuel tank to its capacity and treating it with a stabilizing agent is recommended. This ensures that your generator will run properly when the need arises. Finally, always perform scheduled maintenance which is at least once a year for inverter generators.
