As we rely more and more on electronic devices, portable generators are becoming an increasing need in our lives. For backup power, remote locations or camping, having portable power is swiftly shifting from luxury to necessity. The noise these machines create can be intimidating and obtrusive, but we are looking into the changing generator market and searching for the quietest generators for personal use.
Having a generator for emergency or backup power is a good step in the direction of being prepared for whatever comes your way. The need for power on demand is not limited to the emergency situations of bad weather or disasters. Sometimes we want power in remote places.
Selecting Quiet Generators
The output capability of the generator will generally place it in one of three categories. The larger backup generators are 5000 to 10k and can supply power to an entire home, the midsized heavy duty produce 2500 to 5k and are good for construction job sites or running heavy appliances. The generators we will be looking at today are categorized as personal use, up to 2500 watts. Good uses for these generators include smaller needs such as tailgating in a parking lot or camping out in the woods in a tent or a cabin, but you need access to some power.
A good generator can provide you that power in almost any situation, but that power often comes at a cost. Aside from the material costs such as fuel and maintenance, any generator supplying power will come with the unfortunate operational byproduct of noise.
Why Generators are Loud
The nature of an internal gas combustion engine means heat and noise will be produced along with that critical power you crave. A loud generator may be placed further away from your activities to mitigate the noise but that is not always practical. Aside from the practical concern of security, tailgating parking lots fill up fast, and that noisy generator will break up the serene quiet of any camping experience, no matter how far away you place the engine.
However, all is not lost. There has been a significant makeover to the standard portable generator. The growing popularity of inverter generators comes with plenty of benefits, one of them being, the inverter generator is much quieter than its conventional siblings.
Conventional vs Inverter Generators
The inverter generator has an electronic control board that manages the generating system’s efficiency. This smart addition allows the generator to regulate the engine performance according to the electrical load drawn from the system. This “demand according to need” process means the engine is constantly fluctuating its RPMs, revving up at peak power demand and slowing down during lax power draw.
Conventional generators run at a single speed in order to generate consistent power. You’ve witnessed this when you add a new device to your generator and the engine momentarily lags before coming back up to speed and you see the lights dim. This is only an indication of how that engine runs. It is always running at full speed for maximum available output whether you are charging your FitBit or running a refrigerator. The disparity of need is enormous and is wasted in the name of conventional generator systems.
Why Conventional Generators are Loud
This can’t be helped on conventional generators because of how they generate power. Simplified, the engine turns an alternator which is a magnet surrounded by copper coils, the movement induces electricity onto the wire. The generator system is built and calibrated to run at a very specific speed to produce usable power at specified voltage and amperage. When the engine speeds up or slows down, the rotating magnet changes speed and the power output is affected. You get that “brownout” when the engine is bogged down. These brownouts and surges are indications of “dirty” power and are particularly bad for electronic devices that use sensitive microprocessors.
Benefits of Inverter Generators and Clean Power
“Clean” power is regulated to be much more consistent with the power you get at your home and is much safer for your electronics. Inverter generators operate by taking the power from the alternator and feeding through a rectifier that changes Alternating Current (AC) into cleaner and more stable Direct Current (DC). This power is then converted back to AC through an inverter, where this class of generators get their name.
The use of the rectifier and inverter system grants your generator powerful advantages over the conventional, strictly mechanical, generator.
The aforementioned cleaner power is better for your electronics. The electronic conditioning of power requires fewer copper coils and the generator is lighter weight.
Inverter generators are more efficient than conventional generators for two reasons. They can use a smaller engine to generate the same amount of power, and they regulate the engine’s speed according to need therefore eliminating the need to run full speed at all times. This efficiency directly converts to longer run times and less fuel consumption.
The Quietest Generators for Personal Use
This smaller engine is also much quieter. Attenuating the power through the electronics allows for the smaller engine and the flexible engine speed according to needs means the small engine won’t be running at full speed when you are not using the maximum power output.
The compact size of this entire assembly is enclosed in a case. The enclosure is made from sound attenuating materials and insulated with sound absorbing qualities. Inverter generators are also incorporating the latest upgrades in muffler technologies in an attempt to cut down as much of the excess noise as possible.
The result is the quietest possible generator available on the market today. Lighter weight, fuel efficient, cleaner output, and much quieter than the conventional alternatives. Focusing on the sound output for use in general areas where noise can be an issue, here are the quietest generators for personal use.
The Eastern Tools and Equipment model NI2000i is a great generator with solid performance reviews and plenty of standard and additional options in the 2000w class market.
This machine offers a running wattage of 1600 and a start/surge at 2000W. This is standard for this class of generator. The small frame comes in heavier than some of the others in this review at 64 pounds. However, the frame is solidly built and sturdy. The manufacturer rates their run time at half load capacity. Comparably, many others measure at quarter load. For this reason, a direct comparison can only be extrapolated. However, the one gallon fuel tank will run the unit for six hours at half capacity.
Boasting a moderately quiet 52dB, this model is certainly much quieter than the conventional generators of this size and is on the low side of even the better inverter generators in its class. 50dB is rated as the volume of a “private office” so, this 52dB model should impress.
California compliant, this unit can safely be deployed in any state park you are camping in. The control panel offers standard AC plugs, a battery charging port and a 5v USB port for charging your portable electronics. The unit can be connected and run alongside another in “parallel” operation for more demanding needs.
