Yamaha EF2000iSv2

Yamaha is a leader in many aspects and now, they have become one of the best with generators. There are several features and systems which made the Yamaha EF2000iSv2 a great model. It is small, portable, and convenient, but it is still loaded with amazing capabilities and it is truly a desirable unit.

Smart throttle and longer running time
The unit we are reviewing is a newer generation generator. Correspondingly, it has some advantages, compared to older versions. The smart throttle is one of them. The system is actually complicated, so there is no need to explain how it actually works. A much better alternative is to explain what it does. First and foremost, it will match the throttle according to the load. A higher load means higher throttle. As a result, users can expect longer running time on a single time (10.5 hours) and quieter operation. The unit will generate between 51.5 dBA and 61 dBA.

Parallel operation capability
Another feature you will definitely appreciate is the twin-tech system. It allows to the users to connect two generators in order to get a higher energy output and meet more demanding operations. A great addition is the ability to connect a newer, Yamaha EF2000iSv2 and older, EF2000iS versions! Together, they will produce up to 30 amps. In addition, the procedure is simple and doesn’t require any special knowledge, although, future owners will need a cable for connection.

Pulse Width Modulation or PWM
Here we have another system that is desirable. Using clever technologies, the generator has the ability to adjust and maintain voltage and frequency, within 1%. In other words, the power output will stay the same and be well-maintained regardless of energy consumption. Just to add, the frequency will also be within 1%. For sensitive devices, which require stable electricity, this is an extremely important system and it really makes the generator even better.

Automatic decompression
Starting the generator is easier than ever, thanks to the automatic decompression system. What it does is reduce the comparison in the cylinder. Starting the engine is then much easier, obviously. Once the engine starts, the compression will be restored to normal, meaning that the generator will continue to work in the optimal range. The auto warms up feature is implemented as well. In general, the engine will run on higher RPMs during cold starts. It heats up the engine to the working temperature, allowing the users to get the highest electricity output (1600 running watts and 2000 starting watts) as soon as possible.

  • Auto-decompression for an easier start
  • Automatic throttle control
  • Twin parallel system for linking two generators
  • Auto-warm up of the engine
  • The price is higher than we expected
  • Some units burn oil
  • Cable for parallel connection isn’t included

There are no other words to define the Yamaha EF2000iSv2 except perfection. It is a truly amazing generator, with all the features, quality, and even with superior systems. If the price isn’t an issue, this is the generator to choose from right now.
