Yamaha EF2000iSCH Overview

The beauty of the Yamaha EF2000iSCH is that you can put it to lots of uses because of its versatility and adaptability to changing conditions. The Yamaha 2000 generator will quietly power an extensive range of your applications for an extended duration and is highly portable.

I find the EF2000iSCH easy to transport or store for it is compact (2.2 cu.ft.) and lightweight at less than 45 pounds. This inverter generator will give you an amazing 10.5 hours when running at 50% of its full load capacity. It is beautifully designed with a camouflage-inspired, outdoorsy design. The EF2000iSCH is certainly an upgrade from the older Yamaha EF2000iS in more than one aspect.

Yamaha has designed the EF2000iSCH around an innovative inverter system capable of delivering cleaner, higher-quality electricity than most rival generators. Energy is produced as pure sine waves which make them more reliable and cleaner than the majority of commercial power sources. It has easy controls access and the handy fuel gauge allows you to know fuel level at-a-glance. It comes with two outlets (120V AC) and a single 8A 12V DC Outlet —for charging your batteries plus cables.

​How Does the Yamaha 2000 Watt Generator Perform?

The EF2000iSCH 2000 Watt generator is made with lots of smart features designed to make your life easier. One such feature is what Yamaha refers to as Smart Throttle. This automatically changes the generator engine speed so that it coincides with the changing electrical demands. This ensures that your generator preserves fuel and runs efficiently, enabling it to serve you for a longer period before the need to refuel arises.

The generator features the proprietary Yamaha TwinTech capability. This is a parallel function designed to make it easy to squeeze up to 3,600 Watts and 30 Amps of more power by linking up two of these Yamaha EF2000iSCH generators using an accessory cable. Another great feature, Auto Warm-Up allows you to boost the engine speed of your generator during cold starts to cope with appliances that demand high power right away.

For durability and optimum heat dissipation, this unit boasts of an air-cooled 4-stroke powerful OHV engine that comes in a cylinder liner made of cast-iron. You will conveniently charge your batteries using the included cable through the Yamaha 2000 Watt generator’s 12V 8-Amp DC outlet. Thanks to the RealTree® AP™ camouflage pattern the Yamaha 2000 generator has a great outdoor look.

If you are asking what the Yamaha 2000 watt generator can do, let me tell you! I have run pumps, air compressors, furnaces, and hot plates on this amazing unit, both indoors and outdoors. I have even used it as a window air conditioner when out camping. This is certainly one little powerhouse you cannot afford to miss in your arsenal.

How silent is the EF2000iSCH?

A major drawback with most portable generators is how loud they tend to be. Personally, noise drives me nuts as I tend to lose my concentration and enjoyment. Thankfully, the EF2000iSCH runs quietly thanks to the noise blocking body design that has a molded casing made using noise-absorbing glass wool. That is something you will not find in other similar generators. At below 58dBA, the Yamaha EF2000iS is designed to be extremely quiet. It is fitted with one of the most technologically sophisticated mufflers from Yamaha that has a USFS-approved spark arrestor. To further reduce noise, the Yamaha 2000 generator has vibration isolation feet made of rubber.

Nowadays, there’s absolutely no excuse for buying a loud inverter generator. Sure, it’s possible to get a cheaper one than the EF2000iSCH but I can guarantee you that the noise will drive you crazy. Even when the Yamaha EF2000iSCH is running at full engine speed, I can still have a very normal conversation without having to raise my voice or even talk on my mobile phone without any stress. We love using this Yamaha generator for tailgating and the amazing thing is that we can’t even hear ours over the drone of other models. The EF2000iSCH is one quiet unit for a portable for a generator.

How Reliable and Portable is the Yamaha 2000 Generator?

Efficient, powerful and reliable, the Yamaha EF2000iSCH will give you maximum output without in any way sacrificing portability. Built around Yamaha’s innovative inverter system, EF2000iSCH is more efficient than its competitors or predecessors like the Yamaha EF2000isv2 and it can generate 2,000 Watts of cleaner electricity. It’s capable of serving you continuously for nearly 10.5 hours without refueling as it employs premium technologies in maximizing fuel efficiency. The pure sine energy waves are not only more reliable and powerful but cleaner.

The Smart Throttle feature enables the engine speed to vary depending on load thus improving fuel economy as well as noise levels. The auto-decompression system helps in reducing compression to facilitate easier starting. The auto warm-up feature of the Yamaha EF2000iSCH allows you to increases engine speed to handle high power energy appliances. The new programming gives you more control over a broader range of applications compared to the previous generation of generators like the Yamaha EF2000isv2.

Anything You Need to Know about EF2000iSCH Maintenance?

The Oil Watch Warning System from Yamaha prevents damage to your generator engine caused by low oil thus averting potentially costly repairs. The feature also helps in minimizing downtime. You can prevent damage caused by stale fuel when you store the unit by using the Yamaha gasoline petcock feature. This shuts off the gas completely so that you run the engine carburetor dry.

Just in case you intend to use the EF2000iSCH extensively, a convenient parallel feature allows you to connect two generators with a potential of 30 Amps. As you buy the Yamaha EF2000iSCH, you also get a 2-year warranty.

Why Should You Get the EF2000iSCH?

This unit is engineered to bring durable and quiet power to the outdoors. The impressive 2000 Watts and increased versatility will easily cope with the majority of higher load applications such as heaters, hair dryers, tire warmers, microwaves, and much more.

The Yamaha EF2000iSCH is a high-quality generator unit with an easy-to-carry design. Whether you are out camping, tailgating, hunting or prepping, this is the portable generator you need. The Oil Watch Warning feature prevents potential engine damage due to low oil, helping you avoid costly repairs as well as reducing downtime. At a glance, a fuel gauge allows you to see fuel levels whenever you want. This definitely boosts confidence and gives you peace of mind.

In particular, I like the Yamaha 2000 generator’s fuel gauge. Like me, I am sure you will not want to be worried about fuel levels when you are out there doing your thing. At 10.5 hours when running at half its load, you are certainly getting an excellent return for a unit weighing below 50 pounds. One thing you are going to enjoy is the quiet running of the 2000 generator courtesy of the Yamaha Noise Block Sound Reduction feature. With this unit, I don’t have to worry about disturbing my neighbors!

Yamaha generators have consistently received the longest engine durability ratings from both the California Air Resources Board and the Environmental Protection Agency. And don’t forget that when you buy the Yamaha EF2000iSCH it comes with a 2-year manufacturer warranty.

It’s so nice and courteous not to disturb your neighbors whether tailgating, camping or just partying. The 2000 Watt generator helps me to achieve that as it runs efficiently especially when on the eco-mode. The "eco-mode" setting tapers down the generators engine throttle and noise levels when you don’t require a full load. Additionally, at half-throttle or less, it is amazingly quiet.  Yes, even with the Yamaha EF2000iSCH running in the background at half load, it’s actually possible to have a quiet conversation under the evening skies.

Does the EF2000iSCH Have any Shortcomings?

The biggest shortcoming is the power of the Yamaha EF2000iSCH. Coming at a max of 2,000 Watts, don’t plug in each and every appliance in your house or RV camper simultaneously and expect it to run everything. It can also be hard to start this unit and you may want to have several practice runs at home rather than waiting until sunset when you are on the other side of the lake or mountain!

The Yamaha EF2000iSCH generator is only capable of producing a maximum of 1600 Watts although it can hit close to 2000 Watts for about a minute or so. However, the overload indicator comes on when it goes any longer than a minute. Once illuminated the breaker trips and your generator revs down. Until it’s restarted, you will be without electricity.

The higher portability features translate to lower size and power effectively meaning that if you want a generator that can power a relatively big home or during power outages, this may not be your best option.

Conclusion

Overall, I rate this 2000 Watt generator as one of the best generators today. It may not be the cheapest but certainly one of the best inverter generators. It’s portable, efficient, quiet, and well-engineered for maximum power. Just don’t expect it to power everything in your entire household for a full day but as long as it’s bought for the right practical reasons, I see no reason why it will not make you happy.

Carrying the Yamaha 2000 generator around is easy as it weighs below 50 pounds and storing is convenient as it is just 2.2 cubic feet in terms of size. When I combine the portability, Smart Throttle feature, easy storage, quiet efficiency, and the camouflage design, personally, I couldn’t ask for more from this upgraded inverter generator.
