Yamaha EF2400iS 2,400 Watt 171cc OHV 4-Stroke Gas Powered Portable Inverter Generator (CARB Compliant) Review
I purchased a Yamaha 2400ishc inverter generator through Amazon and we are delighted with the service and the performance. The generator was purchased from SW trading in Utah and arrived early. Upon taking it out of the box I oiled and gassed it, turned on two switches, set the choke, pulled the recoil starter and the engine sprang to life, and quietly too.
We have a 33 foot travel trailer with a Dometic 13,500 BTU rooftop AC unit. At first the Yamaha would not run it but after some research I found that by installing a hard start capacitor on the AC unit everything worked perfectly. I am writing this from within my RV in 90 degree heat and the Yamaha is quietly purring behind me while the temperature inside is 78. The only items I cannot use with the AC on are the mocrowave or a hair dryer, otherwise everything will work while the AC is running including the TV, hot water heater, water pump, battery charger for my electric scooter, this computer and all the lights. You can't do better than that for the money.
Last night a fellow camper came to our door and asked if we knew the people in the rv next door because their "loud" generator was keeping him up. I said no, but my Yamaha is running and I will turn it off if you want me to. He responded by saying the Yamaha was fine, it was the Honda that was too noisy. Go figure, the Yamaha is 400 watts more powerful than the Honda.
By the way, if you decide to purchase a Yamaha 2400is, be sure it is an ISHC. THE HC is the newest model and the one most likely to run a 13,500 AC unit.

 The OHV engine provides excellent heat dissipation for long life. View larger. |
The EF2400iS is built around an innovative inverter system, which is able to deliver higher-quality, cleaner electricity than competing generators. It produces energy in the form of pure sine waves, which are cleaner and more reliable than most commercial power sources.
In simpler terms, this means that you'll be able to confidently power delicate machinery, such as products with built-in microcomputers or microcomputer-controlled electric tools, without having to worry about the damage caused by unrefined energy. An electrical overload breaker is also included, to prevent generator damage in case of an unexpected overload.
 Detachable side panels allow for easy maintenance. |
The EF2400iS is exceptionally fuel efficient, able to run for up to 8.6 hours without refueling when in Economy mode. Its OHV engine runs reliably and dissipates heat efficiently, allowing for both a long life and optimal fuel consumption.
With its Smart Throttle Load feature, the generator is able to dynamically adjust engine speed depending on output, resulting in greater overall fuel efficiency. The generator also features an exclusive multipole alternator, which has a light, compact design with a great power-to-weight ratio for fuel economy.
Ergonomic, User-Friendly Design
Featuring a die-cast aluminum frame, the EF2400iS weighs only 70 pounds. It is ultra-portable and features comfort-grip handles and an easy-to-carry design. It has a convenient, centralized control panel, which allows you to easily access all of the generator's features at the push of a button. It also starts up responsively due to its auto-decompression system, which reduces compression and makes startup less difficult.
 TwinTech technology allows you to hook up two units for 4,600 watts of power. View larger. |
Noise Reduction for Quiet Operation
The EF2400iS uses sound reduction technologies to ensure the quietest operation possible. Featuring a special sound-blocking design, the generator has noise-absorbing glass wool construction, which helps dampen noise even during heavy operation. And along with the EF2400iS' super-quiet muffler with USFS-approved Spark Arrestor, as well as vibration-isolating feet, this generator keep noise at a minimum (53 to 58 dBA).
The EF2400iS is backed by a two-year warranty.
