Yamaha EF2000iS Review | The Best Inverter Generator?
UPDATED Yamaha EF2000is Review – We decided to take another look at this Yamaha inverter generator and see if the customers are still weighing in with high marks. We even added a little section to the right of Buy Quiet Generators.com – so that it would update daily. As you can see – the Yamaha EF2000is is still this highest ranked portable inverter generator out there.

3) How To Connect 2 Yamaha EF2000is Generators Together
Over and over again, the Yamaha EF2000is continues to impress those who have bought it. If you look at the Generator Comparison chart you will see it is also the most quiet generator out there – 51.5 dB is the lowest and they have it. As some have said, you get what you pay for.
A Few Yamaha EF2000IS Considerations
As of the time of this post (which was originally back in January 2011), the Yamaha EF2000iS 2,000 watt portable inverter generator is leading the way with excellent reviews from those who have purchased it and used it. It is a very quiet inverter generator that can be used for camping, RVing, tailgating, fishing outings or any other outdoor pursuit. Of course it would make a great back up generator in those times of power outages, storms, you name it.
One consideration to look at is the fact that it does NOT come with oil, an oil spout, gas can or generator power cord. This Yamaha EF2000iS review can say it does come with the cord that will allow you to charge batteries: 12v output designed for charging vehicle or boat batteries DC outlet – (cables included)
Another possible drawback for some folks will be the price. It is definitely more expensive than comparable models – yet this doesn’t seem to deter those looking for quality and quietness in their generator. I would say do NOT pay more than $1,089.10 (as of this writing) I have seen it selling for over $1,300.00 and there is certainly no reason to pay those amounts.

Powerful Inverter System Delivers Cleaner Electricity
The EF2000iS is built around an innovative inverter system, which is able to deliver higher-quality, cleaner electricity than competing generators. It produces energy in the form of pure sine waves, which are cleaner and more reliable than most commercial power sources.
In simpler terms, this means that you’ll be able to confidently power delicate machinery without having to worry about the damage caused by unrefined energy. An electrical overload breaker is also included, to prevent generator damage in case of an unexpected overload.
Smart Technologies for Optimal Fuel Efficiency
The EF2000iS is exceptionally fuel efficient, able to run for up to 10.5 hours without refueling when in Economy mode. Its OHV engine runs reliably and dissipates heat efficiently, allowing for both a long life and optimal fuel consumption.
With its Smart Throttle Load feature, the generator is able to dynamically adjust engine speed depending on output, resulting in greater overall fuel efficiency. The generator also features an exclusive dual coil alternator stator, which lowers engine speed and reduces total fuel consumption.
Ergonomic, User-Friendly Design
Weighing 44 pounds, the generator is ultra-portable and features an easy-to-carry design. It has a convenient, centralized control panel, which allows you to easily access all of the generator’s features at the push of a button. It also starts up responsively due to its auto-decompression system, which reduces compression and makes start-up less difficult.
For added convenience, the EF2000iS is able to recharge batteries with its 8A12V DC output, making it ideal for RV, auto, and boat owners. You can even hook up two EF2000iS units for added output, thanks to TwinTech technology. And you won’t have to worry about engine damage due to low oil levels: an oil-watch warning system constantly monitors oil levels and lets you know when an oil change is needed.
Noise Reduction for Quiet Operation
The EF2000iS uses noise reduction technologies to ensure the quietest operation possible. Featuring a special sound-blocking design, the generator has noise-absorbing glass wool construction, which helps dampen noise even during heavy operation. Along with the EF2000iS’ super-quiet muffler and vibration-isolating feet, it helps keep noise to a minimum.
The EF2000iS is backed by a two-year warranty.
