Advanced Inverter Technology with Pulse Width Modulation - Clean Power for Sensitive Electronics

The “iS” in EF2200iS stands for “inverter” and “silent,” highlighting two of its most crucial features. Unlike conventional generators that produce raw, unregulated AC power, the EF2200iS utilizes sophisticated inverter technology to generate clean and stable electricity. This is achieved through a multi-stage process: the engine first generates high-frequency AC power, which is then converted to DC power. Finally, the DC power is inverted back to AC power using a process called Pulse Width Modulation (PWM). PWM creates a smooth, pure sine wave output that is essential for the safe and optimal operation of sensitive electronic devices like laptops, smartphones, and medical equipment.

Why is a Pure Sine Wave Important?
Many modern electronics are designed to operate on a pure sine wave, which is characterized by a consistent voltage and frequency. Conventional generators often produce a modified sine wave or a square wave, which can contain harmonic distortions. These distortions can lead to overheating, malfunction, and even permanent damage to sensitive electronics. The EF2200iS’s pure sine wave output, thanks to its advanced inverter technology and PWM, ensures that your devices receive the clean and stable power they need to function correctly and last longer. The inverter system also enables the generator to automatically adjust its engine speed to match the load, resulting in better fuel efficiency and reduced noise.

Yamaha Quiet Technology - Power Without the Disturbance

Noise is a significant concern with traditional generators, often disrupting the peace and quiet of both residential areas and natural environments. Yamaha has addressed this issue with its proprietary Quiet Technology. The EF2200iS is outfitted with a specially designed, sophisticated muffler that significantly reduces noise levels to a mere 57-65 dBA. For comparison, a normal conversation typically registers around 60 dBA.

Understanding Decibels (dBA):
The decibel (dB) scale is a logarithmic scale used to measure sound intensity. An increase of 10 dB represents a tenfold increase in sound intensity. The A-weighted decibel scale (dBA) is adjusted to reflect the perceived loudness of sound by the human ear. The EF2200iS’s low noise level of 57-65 dBA, confirmed by numerous user reviews, ensures that it can be used in noise-sensitive environments without causing significant disturbance, making it ideal for camping, tailgating, and residential backup power. Many users appreciate its quiet operation, with one user stating, “Those who say it’s loud need a psychiatrist. It’s very quiet like the Yamaha 2000IS it’s replacing.”

Smart Throttle - Intelligent Load-Sensing Technology

The EF2200iS incorporates Yamaha’s Smart Throttle technology, a load-sensing feature that automatically adjusts the engine speed to match the power demand. This intelligent system optimizes fuel efficiency and reduces noise levels by ensuring that the engine only works as hard as necessary. When the power demand is low, the engine runs slower, conserving fuel and minimizing noise. When the demand increases, the engine speeds up to provide the required power.

How Smart Throttle Works:
Smart Throttle utilizes sensors to continuously monitor the electrical load connected to the generator. It then communicates with the engine’s electronic control unit (ECU) to adjust the throttle position and engine speed accordingly. This dynamic adjustment ensures that the generator operates at the optimal speed for any given load, maximizing fuel economy and minimizing wear and tear on the engine. User reviews often highlight the effectiveness of Smart Throttle, with many users reporting significantly longer run times than expected, especially at lower loads. With a fuel tank capacity of 1.24 gallons and Smart Throttle, it will run up to 10.5 hours at 1/4 rated load on a tank of gas.
