More often than not, people already have certain brands on their list whenever they shop for inverter generators. Two of the huge brands in the inverter generator industry are Yamaha and Honda. In this article, we will review both the Yamaha and Honda Inverter Generators. In this manner, we will be able to learn the strong and weak points of each brand’s generators. 

Yamaha Inverter Generator

For 20 years, Yamaha has provided its customers with the best power products at a valuable price point. Their product line-up of inverter generators promotes safe and quiet models and clean electricity. The brand’s models are highly rated and top ranked for reduced noise emissions, power quality and delivery.

Overall, Yamaha inverter generators are designed to deliver quality power and electrical output without compromising portability.

Major Features of Yamaha Inverter Generators

  • Produce more controlled and clean power. Through a controlled electrical circuit process called Pulse Width Modulation (PWM), Yamaha’s inverter system is able to produce AC current. This greatly eliminates the effect of engine speed fluctuation to the voltage or frequency of the electrical output. 
  • Adopts a Highly-Efficient Multi-Polar Alternator. The alternator enables the generator to be more efficient, with high frequency, 3-phase AC current. The current is turned into a single phase of electricity. With Yamaha’s highly efficient alternators, a much lighter and more compact generating unit is achieved. The multi-polar is more functional than conventional 2-pole rotor type alternators.  
  • Economic Idle Control – Smart Throttle. Yamaha created Smart Throttle, a feature that automatically adjusts the engine speed to precisely match the load. This feature allows the generator to run quieter while increasing fuel efficiency, prolonging engine life and extending running time between refueling. 
  • Advanced Sound Reduction. Yamaha created Noise Block, an acoustically engineered sound reduction system. The feature enables silent operation while maintaining quality performance. With its various sound absorbing materials, molded cases, intake silencer, fibreglass insulation and uniquely designed muffles and fans, the inverter generator is set to operate efficiently and more quietly.
  • Less Than 2.5% Distortion Ratio. The distortion ratio result means that Yamaha inverter generators can be used with equipment that require stable frequency and voltage. Examples are power tools and projectors with built-in computer functions and microcomputer controlled equipment.

Additional Features of Yamaha Inverter Generators:

Besides the aforementioned general features, here are other functions and features that make Yamaha inverter generators to be among the best in the industry.

  • TwinTech: This basically allows Yamaha inverter generators to have the parallel use function. Easily hook up two generators with similar specifications for an approximate double power output while maintaining the frequency and voltage of a single generator unit. 
  • Electronic Circuit Breaker: Once the output voltage exceeds the designated maximum output capacity, the inverter generator automatically cuts off current. 
  • 4-Stroke OHV Engine: The four stroke OHV engine consists of powerful performance, precise valve actuation, excellent heat dissipation, low fuel consumption and reduced noise level.
  • Oil Warning System: When the oil level is low, the engine automatically stops to prevent engine damage that will minimize costly repairs.
  • Electric or Non-Fused Overload Breaker: The overload breakers prevents damage on the generator by automatically reducing power output. 
  • Auto Decompressor and Electric Starter: This function allows for an effortless start through the light recoil start that reduces compression. 
  • Petrol Petcock: The petrol flow is turned off to reduce carburettor contamination during storage and this also allows the carburettor to run dry.
  • DC Output Capability: This capability allows for convenience of charging the battery. 
  • Fuel Gauge: The gauge is exposed externally. In this manner, the fuel level is displayed without the need to open the fuel cap. 
  • Voltage Meter and Brushless Alternator: Yamaha inverter generators only require minimal maintenance, hassle-free service and clean output. The voltage meter is clearly displayed on the control panel. 
  • Spark Arrestor and Long Range Fuel Tank: Yamaha inverter generators have improved efficiency and longer running time. The spark arrestors are USFS-approved to contain sparks from exiting the exhaust system to reduce the risk of unnecessary sparks that could cost fire.

Below we have handpicked the best Yamaha inverter generator suitable for residential use that will surely deliver the value of your money.

Honda Inverter Generators

The Honda company has been in the automobile and power industry since 1953. They have manufactured millions of power products delivered worldwide. Honda power equipment has 6 different major product families; generators, lawn mowers, pumps, snow blowers, tillers, and trimmers.

Besides that, Honda boasts of a network of thousands of independent dealers across the United States and not counting the countries in Asia. 

Major Features of Honda Inverter Generators

  • High Quality Power Output. Honda inverter generators produce power that is as reliable as the power obtained from outlets at home. The brushless inverter technology used on units ensures that power is closer to “line power” than any other generator design. 
  • Lighter, Smaller Size. The inverter technology used in the unit integrates parts from the engine and the generator. In this manner, the alternator on models EU1000i, EU2000i, and EU3000iS is combined with the engine flywheel for reduced size and weight. 
  • Higher-Fuel Efficiency. The Eco-Throttle feature of Honda inverter generators allows the engines to automatically adjust the speed to produce only the power needed for the application in use. It is said that traditional generators have to run at 3600 RPM to produce 60 hertz of electricity. But generators with Eco-Throttle can run at much slower RPMs while maintaining frequency and power for the requested load. Due to the reduced RPMs, the Eco-Throttle feature reduces fuel consumption by up to 40%. This helps reduce exhaust emissions.
  • Quiet Operation. The Eco-Throttle feature is also capable of reducing the noise level of inverter generators. Due to the fact that the engine is not running at full speed constantly, it is much quieter. Honda inverter generator units also consist of sound dampening materials and quiet Honda engines that help make the units incredibly quiet.
  • Parallel Capability. Basically, the parallel capability of Honda inverter generators allows the usage of two smaller, lighter generators to do the work of a much larger generator, without sacrificing the portable feature.
