Standard portable generators or generators without automatic voltage regulation supply plenty of power but this power can vary somewhat and it can have a higher noise ratio that can damage sensitive electronic devices.
To combat this, power equipment manufacturers have introduced inverter generators that supply a steady stream of near perfect sine wave energy. These won’t damage sensitive electronics and they can be linked together to scale the power to demand.
The power coming from your home outlet is Alternating Current, as opposed to the Direct Current like you find in your car. A normal generator consists of an engine and alternator that converts rotary energy into electrical current and dispenses it as AC electricity at a 60 Hertz cycle.
An inverter generator works basically the same but runs the current through an inverter that converts the AC to DC and then back to AC.
The AC is still at 60Hz but it is now more even and with less THD or total harmonic distortion. (a.k.a. noise) This AC is comparable to the utility grade power that you find in your home.
Also, this process can be increased in dimension by adding another inverter generator in parallel to the original generator. This adds more wattage to the end result. For example, a 1K Watt inverter generator in parallel with another 1K Watt inverter generator produces 2K watts of power. Thus allowing you to increase the power generation in response to your demand.
This can be important for RV users as their demand can change depending on the circumstances and usage in the vehicle. It is true, that inverter generators tend to be more expensive but when you consider that you are protecting all your devices from damage, it becomes worth the investment.
Five Great Inverter Generators For the Money
Best Quiet Camping Inverter Generator
A basic inverter generator that is great for camping, tailgating and charging devices. The Powerhorse 2K Inverter Generator has 2000 Watts of surge capacity and a continuous generation of 1600 Watts. The total harmonic distortion is less than 1 percent making it the equivalent of utility power in your home.
It has two three prong outlets and a 30A twist lock for RV use. It has a front parallel port for easy connecting another Powerhorse generator.
Purchasers of this generator speak very highly of how quiet this generator runs and how well it performs at providing steady power.
Best Rated Inverter Generator
It comes as no surprise that the leading manufacturer of batteries has moved into the power generation market. The Duracell Model #DG2.0i Inverter Generator has a surge capacity of 2000 Watts and a continuous generation of 1600 Watts.
It has a larger than normal tank for a longer running time and it comes with the standard features found on many inverter generators including dual outlets, a 12 volt connection and more.
It comes with a two year warranty, including two years on the alternator. People who have purchased and used this generator love how quiet it runs and how easy it starts.
Top Rated Portable Inverter Generator
The Briggs & Stratton Model #30651 Generator produces a surge capacity of 2200 Watts and a continuous generation of 1700 Watts, plus the parallel port allows you to connect up to two more generators for up to 6600 Watts of surge energy.
It has a USB port for charging devices and a DC lighter style port for other connectivity, plus the standard dual outlets. People who bought this generator loved the power output, the fast starting and the quiet operation.
Highly Reliable Inverter Generator
Yamaha is one of the top names in power generation equipment and this generator offers the same quality and dependability found with other Yamaha generators. Fully CARB compliant, the Yamaha Model #EF1000iS Generator has 1000 Watts surge capacity and 900 Watts of continuous generation.
It has the standard connectivity options but it also has a load sensing throttle thus it is capable of running up to 12 hours before refueling. People who have this generator love how portable and super quiet this generator is and how clean the power delivery is as well.
Ultimate Large Inverter Generator
The Champion Power Equipment Model #75531i Generator is a larger generator than the rest but it still provides the clean and steady energy required. It has 3100 Watts or surge capacity and 2800 Watts of continuous generation. It is also lightweight coming in at 80 pounds with a wheeled case for extra easy mobility.
Super quiet and with dual operating modes that adjusts to the power demand, this generator is also fuel efficient.
It has the standard connectivity as other inverter generators including a 30A plug for RV use. People who use this generator love the quiet power delivery and the two year warranty. When you need clean and stable power, this generator will be there to keep your power flowing.
Importantly, practice safe fueling by allowing the generator to cool before adding additional fuel.
Do not use in spaces that are closed in, including garages with the doors open as the fumes will still accumulate and as always, read the operator’s manual before using your generator for the first time.
