Silence is subjective. What constitutes annoying noise for any one person may barely be noticed by someone else. It's also fair to say that a 100pc silent home generator does not exist, give the power that the units much generate in order to provide backup for when your mains electricity shuts down during an emergency, or in situations where you have no access to mains power.
But when people speak of finding a silent home generator, what they actually mean is that they are looking for the quietest unit possible. Admittedly, these are most likely to be the portable appliances, but we deal with those elsewhere on this site on a post devoted to the most silent portable generator units.
When you step up a gear from portable, what is available in terms of silent home generator units or systems that are going to be so quiet as to not intrude on you or, indeed, your neighbours?
Our team judged these to the be 10 most silent home generator appliances, or the machines that would be considered least intrusive in noisy terms by general opinion.
Running from 55dBa, the Westinghouse WGen7500 is also an all-round efficient home generator. This can undertake extremely demanding power generation workloads without fuss or annoyance to anyone, making it especially prized in the home.
The WGen7500 is also reliable and user-friendly, with numerous attractive, easy-to-use features, including its intuitive controls, rubber-covered GFCI power outlets, and steel frame with roll bars to protect the generator's 6.6-gallon gas tank.
The WGen7500 is covered by a three-year warranty, and there is also access to Westinghouse's nationwide network of service and support technicians.
The Sportsman GEN4000LP can handle just about any power backup task, so it's a pleasant surprise to discover that this is also one of the best quiet to silent home generator appliances.
Operating from 68dBA, the Sportsman can run on gasoline or propane and, with a 50 percent load, can run for up to 10 hours on a full 3.6-gallon tank of gas. It can also run for 12 hours with a full 20lbs LP gas grill-type cylinder (not supplied).
Given the power packed by this, it's one of the best silent home generator units.
DuroStar DS4400 is as reliable as you would expect for a generator from this manufacturer. It's a failsafe power backup generator when you need it most, and its noise levels make it particularly suitable for the home, running at 69dBA.
We also included the DS4400 in our review of silent home generator machines as we admire its all round versatility. It's rugged and robust, yet very portable, so it can also be used on, for example, camping trips where you don't want to annoy your Great Outdoors neighbours with noise!
The Duromax's XP4400E may be a beast of power backup, but it's another machine in our silent home generator roundup that runs surprisingly quietly. Despite its powerful 7.0HP air-cooled OHV engine, whose 3500W (max 4400W) output is sufficient to fully power a small house, the XP4400E emits 69dBA.
The muffler design of the machine keeps the noise to a minimum, meaning that you can use it without any nuisance in the home, or out of doors on campsites, etc. This generator has a 4-gallon tank, and the unit can deliver up to 8 hours of continuous power at 50% load.
Emitting noise levels from 70dBA, the Generac 5734 underscores the reputation of its manufacturers as a producer of superior power generators that are efficient, reliable, and cause little or no annoyance regardless of circumstances.
Driven by the powerful Generac OHVI engine, this appliance has sufficient power to operate air conditioning systems of up to 5 tons. The quiet operation of the unit is the cherry on the cake for anyone seeking a great all-round power backup solution.
The DuroMax's XP10000EH is rightly acclaimed for its dual-fuel flexibility—giving the user the choice of running on gas or propane—and its relatively quiet noise emission of 72dBA is another reason to get excited about the unit.
It's also user-friendly, with an electric start option, while its suitability for the home is enhanced by its portability, an easy proposition thanks to its 10.5in pneumatic solid=fill tires and flip-up handles. The XP10000EH has a 10-hour running time at 50% load, and its quiet exhaust also comes with a built-in spark arrestor.
We couldn't leave the user-friendly Champion Power Equipment 100165 7500 Watt Dual Fuel Portable Generator out of our roundup of the best silent home generator units. It's easy to use, and is powerful whether on gas or propane.
On gas, the unit produces 9375 starting watts and 7500 running watts, and on propane 8400 starting watts and 6750 running watts. Easy to use with great inbuilt features that enhance its efficiency, the noise generated by this powerful little performer is just 74dBA.
The Sportsman GEN10K works well whether indoors or outside. Powerful and rugged, the Sportsman GEN10K makes our list of silent home generator units by virtue of its reliability and sheer power. Added to this is its operational noise level.
The GEN10K, which can handle pretty much any domestic power requirement demanded of it, runs at just 74dBA, making this another of the best quiet home generator units, without question.
Briggs & Stratton is one of the most reliable power brands. The 30664 produces 8000-watts of power, emits 81dBA, and can run a plethora of large appliances and power tools simultaneously, delivering up to 9 hours of continuous operation at 50pc load on a full tank.
It's portable too, and rated in accordance with CSA and rated in accordance with PGMA standards. The machine also has a 3-year limited warranty to protect against defects in materials and workmanship.
