Distinguishing Features of Yamaha Generators

  • Noise Block system– this is an acoustically designed sound reduction system that involves placing noise-absorbing materials at strategic areas inside the generator for increased noise reduction.
  • Auto warm-up– a common feature in Yamaha motorbikes, the auto warm-up increases engine speed for around 6 minutes for efficient and safe engine warming during cold startups.
  • Smart Throttle control– this is a load-sensing intelligent system that adjusts motor speed to match the load in Yamaha inverter generators. This results in noise reduction and improved fuel efficiency.
  • Dual coil alternator stator– this exclusive technology further reduces fuel consumption and noise level besides minimizing engine wear.
  • Auto choke– this feature makes starting the generator much easier, especially when it’s cold.
  • Brushless motors– Most open-frame Yamaha generators use brushless motors leading to a higher torque to weight ratio and increased efficiency, reliability, and overall durability.
  • Oil Watch Warning System– This oil-level alert feature prolongs engine durability and performance by warning you against dangerous low oil levels.

Moreover, most Yamaha generators come with a 3-year warranty covering most of the critical components.

This Japanese manufacturer is known for its cutting-edge sound-reduction technologies, including Noise Block system and Dual Coil Alternator Stators that keep the noise levels below average at all generator sizes, making them a good choice for a quiet portable generator.

Lastly, although Yamaha generators are pricey, you get a lot of bang for the buck thanks to their inexpensive maintenance needs and durability. Although many factors affect longevity, we expect a Yamaha generator to last 20-40 years with proper use and timely maintenance.
