The Yamaha brand has a reputation for impressive and high-quality equipment. No less impressive is their selection of inverter generators. This article reviews two of the most popular models; the Yamaha EF1000iS and EF2400iS.
Yamaha EF1000iS Generator
The Yamaha EF1000iS is one of the most powerful, efficient and portable solutions for all your power needs. Its innovative gas-powered inverter is able to deliver maximum electrical output without sacrificing portability, generating up to 1000 watts of clean AC power.
Many consumers have praised this generator for its ability to run for continuously for up to 12 hours without the need for refueling, which is due to the use of premium Yamaha technologies for the maximization of fuel efficiency. This model is able to deliver higher quality cleaner electricity than competing generator models because its inverter system produces energy in the form of pure sine waves, which tend to be cleaner and more reliable than most other commercial power sources.
The overall fuel efficiency of this unit is enhanced by the presence of its Smart Throttle Load feature which allows the generator to dynamically adjust its engine speed depending on output. Additionally, its exclusive dual coil alternator stator allows for the reduction of both the engine speed, as well as the total fuel consumption.
Weighing a mere 27.6 pounds, the Yamaha EF1000iS is also very portable and comes in an easy to carry design, making it very user friendly. Its centralized control panel conveniently allows you easy access to all of its features by simply pushing a button. What makes this generator model even more attractive to users is the fact that it is able to recharge 12-volt batteries with 12-volt DC output, which makes it the ideal choice for those who wish to take it along for use in their RVs, boats and automobiles.
Its noise reduction technologies - including a special sound-blocking design, noise-absorbing glass wool construction and super quiet muffler - work to ensure that it provides the quietest yet most efficient operation possible.
Yamaha EF2400iS Generator
The Yamaha EF2400iS generator model comes in an efficient and powerful design, whose gas-powered inverter is able to deliver maximum electrical output without sacrificing its portable design. The innovative design of its inverter system enables this unit to generate up to 2400 watts of clean AC power, and continuously run for up to 8.6 hours without refueling. This generator produces high quality clean electricity by producing energy in the form of sine waves.
Many consumers have been happy with this unit due to the fact that it enables them to power delicate machinery such as products with built-in microcomputers or microcomputer controlled electrical tools confidently, without fear that they could be damaged by unrefined energy. This model also comes with an electrical overload breaker which helps to prevent generator damage in the event of an unexpected overload.
It has an OHV engine which runs reliably and efficiently dissipates heat, thus enabling the unit to have optimal fuel consumption as well as increase its lifespan. The Yamaha EF2400iS also features an exclusive multiple alternator which comes in a light compact design with a great power to weight ratio for fuel economy. Available in a die-cast aluminum frame, this unit weighs a mere 70 pounds making it very portable and user friendly.
With an auto-decompression system, this generator is able to start up responsively, thereby making start up less difficult, by reducing compression. This unit is also able to recharge batteries with its 8A12V DC output which comes with cables included. Users will be pleased to learn that they can also hook up two units for 4,600 watts of maximum power, because of the Yamaha EF2400iS generator's Twin Tech technology.
