What You Need to Know About Quiet Inverter Generators
Why be concerned with generators under 55 decibels? Because that’s about as loud as you would expect a normal conversation to be. So if you are looking for a generator that creates the lowest level of background noise, you’re in the right place to be doing your research.
These types of engine-generators come with integrated inverters to help convert the AC (alternating current) output to DC (direct current) and then back into a more stable AC. Inverter generators vary their engine speed to generate power on an as-needed basis. As a result, the engine runs quieter and fuel is consumed more efficiently.
In contrast, standard generators have to maintain a constant engine RPM irrespective of the current electrical demand.
Inverter generators are generally preferred for their quieter operation, fuel efficiency, smaller and lightweight form-factor, and cleaner energy output. However, they don’t produce as much energy as their conventional counterparts.
What To Look for In an Inverter Generator
In a sea of brands and varying styles of generators, it is important to refer back to what makes a good quality inverter generator. Beyond going for the quietest inverter generator, you want to consider other factors such as the power output, fuel options, ignition type, and included safety features.
Inverter generators will typically run half as loud as standard open-framed generators, which can go beyond the 100-decibel mark. Additionally, these generators throttle down to match the electrical load resulting in a quieter operation.
Double-check that your inverter generator of choice operates within a range of 50 to 60 decibels.
Power Output
A generator with a high wattage rating equates to higher power output. Manufacturers will typically list the starting watts and running watts in the given unit’s specifications. The starting watts indicate the initial surge needed to start specific power tools and appliances while the running watts are the required power to continuously run the devices.
A generator with a watt rating ranging from 2000 to 3000 watts should suffice for running common household and recreational appliances. These might include fridges, TVs, laptops, air conditioners, coffee machines, small power tools, and outdoor lighting among others.
Inverter generators rated beyond 4500 watts can power a welder or act as emergency power for an entire house. To overcome the power limitations of inverter generators, some models may come with load-sharing capabilities. You simply link two compatible generators side-by-side or stack them up to get double the power.
It is good practice to add up the power requirements for all your devices to get an inverter generator ideal for you. Lastly, your ideal inverter generator must come with multiple outlets so you can plug in most of your appliances and devices accordingly.
Fuel Source
Most inverter generators run on gasoline but some models can also be powered by propane. The main advantage of gas-dependent generators is that gasoline is readily available all across the country. However, gasoline is notorious for slowly evaporating over time and going stale (oxidizing) too quickly.
Gas might even leave tar-like deposits that can easily clog up or accelerate the corrosion of the generator’s components.
Dual-fuel inverter generators get you the best of both worlds – the higher heat content of gasoline and the convenience of using propane.
Propane has a longer shelf life and is easier to store than gasoline. Additionally, using propane affords you the luxury of having an “unlimited” fuel source that is not dependent on the fuel capacity of the generator. With a hose and pressure regulator, you can hook up just about any propane tank size.
Keep in mind that gas-only generators typically have a fuel capacity of just a few gallons. That said, propane generally has fewer BTUs (British Thermal Units) as compared to the more superior gasoline. Moreover, expect to spend a few more dollars on dual-fuel inverter generators than their gas-only alternatives.
As for the ignition type, you have two main options including an electric start or a recoil cord. The recoil cord might require some effort to get things started but is often more reliable than an electric start. An electric start relies on a charged internal battery or else the generator won’t start.
Safety Features
Like with most fuel-powered engines, exhaust gasses containing carbon monoxide (CO) are to be expected when using inverter generators. Fortunately, most models will come with automatic CO shutoff features whenever there’s too much CO build-up.
Other models will also come with low-oil sensors that initiate shutoffs whenever the oil levels are too low.
Portability
The weight and size of the generator must be considered, especially if portability is a concern. Most inverter generators have compact sizes with top handles for easy handling and transportation.
Wheeled units offer even more portability and can have slightly higher power outputs. However, they can be a pain to haul in space-constrained camper vans or truck beds.
