Yamaha EF2000iSv2 Gas Powered Portable Inverter Review
Yamaha is known for its motor sports, but also exceeds at their line of power equipment which adheres to the same standard of quality that was set forth back in 1953. Packed with the latest technology, their line of portable generators display an enhanced power and performance that boast high standards of durability and reliability. This review talks about the great features of the Yamaha EF2000iSv2 Portable Inverter Generator and what it delivers in efficiency, durability, convenience, and more, making this unit one of our Top Ten Best Portable Generators.
When talking about portable generators, first let’s define the differences between inverter and conventional: Conventional generators are the most popular and widely used, having been around the longest. They are gas-powered with a motor that is attached to an alternator, producing electricity at a consistent speed that is usually 3600 rpm to produce the required 120 volt current.
Inverter generators are a relatively new technology that has been made possible through advanced electronics and the highest quality magnets. This functions by outputting AC current like most generators, but then the current is converted to DC voltage and “inverted” back to clean AC voltage. The advantage to this method is that it keeps a constant flow of current to your appliances.
This Yamaha EF2000iSv2 generator uses inverter technology with a Pulse Width Modulation, which is a more sophisticated control circuitry to deliver consistent, clean current that supports better fuel efficiency and durability. Voltage stability is within ± 1%, and frequency stability is ± 0.1 HZ. Worth mentioning, it’s pure sine wave is as clean as or cleaner than the power produced by public utilities. This model runs at 1600 watts and has an air-cooled single cylinder, 4-stroke engine that provides impressive heat control.
The OHV engine is built to last, and includes a steel camshaft and valve train components with a cast iron cylinder liner. There is a smart throttle with a sensor that controls the engine speed, which improves fuel efficiency and helps with noise reduction by automatically adjusting the speed of the engine to match the load.
On one tank of gas, It will run up to 10.5 hours at a one-quarter rated load. Other features include an Oil Watch Warning System that prevents any damage to the engine when the oil is down below the minimum level, protecting the engine from destruction and avoiding any costly repairs.
There is also an electrical overload breaker that will prevent any damage to the generator in case of overload. The fuel gauge can be seen at a glance with the gasoline petcock, allowing you to shut off the gas to run the carburetor dry for storing, and to prevent any stale gas issues.
Equipped with a new controller and advanced programming, this cool retro-style unit has the ability to run a large range of applications than its previous generation EF2000iS and is lightweight, weighing less than 45 pounds for easy portability and storage. This EF2000iSv2 generator is CARB-compliant, which allows for operation in all 50 states.
Easy to start with the auto-decompression system that reduces compression and the auto-warmup works to increase the engine speed during those cold starts to better handle those high-demand appliances. Fitted with a sophisticated, technologically advanced muffler system that includes a USFS-approved spark arrestor, this generator runs so quietly that you can carry on a normal-toned conversation beside one and may even forget that its there. The rubber vibration isolation feet helps the unit operate smoothly and quietly.
Why We Liked It
We like knowing that a lot of smart technology has been applied to this generator, and it shows with a consistent, smooth output of power and a long-lasting operation. This compact, sleek design made it very easy to transport anywhere, and we especially liked the the twin tech parallel operation that allows the connection of another Yamaha EF2000iS model (twin tech cable not included) to provide extra power and performance.
In terms of revolutionary technology, Yamaha cannot be beat. This compact inverter generator provides a lot of the latest and greatest features on the market today, and is jam-packed full of impressive components that work together to make this high-quality Yamaha EF2000iSv2 generator run consistently, powerfully, and efficiently.
