Yamaha RV Portable Generator:


Yamaha rv generator Yamaha Inverter Generator 2400EFiS
  • TwinTechTM capability - Hook up two EF2400iSs for 4600 watts of maximum power.
  • Auto-decompression system - Reduces compression for easier starting.
  • Gasoline petcock - Helps prevent carburetor contamination during storage.
  • Controls all on one panel - Easy access to controls.
  • Smart ThrottleTM varies engine speed based on load - Improves fuel economy and reduces noise.


Yamaha listened to what their customers wanted when they built their latest inverter generator. The result is the EF2400iS. Not only is it super-quiet (53-58dBA), it only weighs 70 pounds and produces 2400 watts of maximum power. Cleaner, quieter and more powerful, the EF2400iS is the next step forward in Yamaha generator technology.

RV generators are a special class of generator sets that are designed to be installed into various types and sizes of vehicles available in the RV industry. This could include special conversion buses, Winabago type campers, large towable campers, and even some smaller camp trailers. Many of these units are installed inside an enclosure underneath the main RV body, but some may be roof mounted or even rear or front rack mounted.

These RV generators can be powered by gasoline, diesel fuel, or even propane gas depending upon what makes the most sense for the particular installation. One of the unique features of these quiet rv generators is the extra sound abatement, and muffling that has been built into the product line. In some campgrounds (including State and National Parks) there are now strict noise limits so that RV campers do not disturb their neighbors, and the acceptance of portable electricity may be grudging (at best). So be aware of the local camping protocols before starting up any power equipment!

The small Yamaha portable camp generator sets are covered here because they sometimes may be purchased in addition to an RV generator, or in the case of a small "pop-up" camper might make more sense than a "real" RV generator. These are really very small lightweight portable Yamaha generators that are usually built to be very quiet during operation. These units generally can only operate a single small appliance at one time, (i.e., a radio, TV, hairdryer, or a couple of lights.)



Generators vs. Inverters: An inverter rv generator is a type of generator that produces electricity in three phases: high-frequency AC, DC, and then stable AC. A conventional rv generator is a type of generator that produces electricity in one phase: AC. Some of the main differences between these two types of rv generators are:

  • Running speed: An inverter generator can adjust its speed according to the power demand, while a conventional generator runs at a constant speed.
  • Power quality: An inverter generator produces power with low THD (total harmonic distortion), which means it is cleaner and safer for sensitive electronics. A conventional generator produces power with high THD, which means it is less stable and more prone to surges.
  • Portability: An inverter generator is usually smaller and lighter than a conventional generator, which makes it easier to transport and store.
  • Efficiency: An inverter generator is more fuel-efficient than a conventional generator, because it uses less fuel to produce the same amount of power. A conventional generator wastes more fuel by running at full speed regardless of the power demand.
  • Noise level: An inverter rv generator is quieter than a conventional rv generator, because it runs at lower speeds and has better sound insulation. A conventional generator is louder because it runs at higher speeds and has less sound insulation.
