Yamaha EF2400iS 2,400 Watt 171cc OHV 4-Stroke Gas Powered Portable Inverter Generator (CARB Compliant)

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.

Yamaha Generator - Popular Models

It would prove hard to distinguish Yamaha generator's popular models. Almost all models in their product line are sought after because of their durability and reliability.

If terms of usage are considered, Yamaha generator models which are the most popular would be the Inverter series. These models are popular because of their portable and lightweight features. The fact that they provide ample power suitable to your need should not be disregarded because of their size. Here are the models of the Inverter series which is considered to be Yamaha generator popular models.

EF2000iS

This model weighs only 44.1 pounds but capable of delivering enough power to take anywhere. Its design comes with an extra large handle for ease in carrying it into work sites or camp sites. It is also equipped with a muffler which is sophisticatedly technological making it quiet as a whisper. Another feature of this model gives a maximum of 30 amps by using a parallel function making it possible to connect two generators with each other. This is said to be the greenest way while providing power requirements as it meets the strictest standards of the environment.

EF3000iSE

This 149.9 pound model delivers 3000 watts of power while operating smoothly because of its Noise Block Technology housing. It has ergonomically designed handles and sturdy wheels make the transportation and transfer of this model as convenient and smooth as it gets. Through the help of Noise Block technology, this model operates at 53-60 dBA making it run quietly as a whisper. This model also has Smart Throttle, Pulse Width Modulation, and Oil Watch Warning System. The EF3000iSE also consumes only a one quarter load when running for 19 hours.

EF3000iSEB

This 154.3 pound model has all the power and features offered by the EF3000iSE. The only thing that sets it apart from the previous model is it has Yamaha Boost Technology making it one of the popular Yamaha generator models. Notice the B added at the end of the products model name. This stands for boost. With the help of the Yamaha Boost technology, output is increased within 10 seconds providing the required power to feed demanding high draw tools. This technology also reduces appliance motor temperature and excessive build up of heat when starting up thereby increasing the appliances' life.

EF4500iSE

The EF4500iSE is one of the popular models of Yamaha because it incorporates the advantages and features of the EF3000iSE and offers additional power at the same time. This 194 pound model is designed to deliver outstanding fuel efficiency and minimal noise when in operation. This is possible because its engine runs at a rate of only 2600 rpm. This low engine speed is 1000rpm slower compared to other generators found in its class. This also has an optional wireless remote control as an added accessory.

Among those included in Yamaha generator popular models is the EF6300iSDE model. This 200 pound model can crank up 6300 watts of pure inverter sine wave power. This generator can power high demand equipment such as RVs well pumps and ideal for outdoor recreational usage.

This only goes to show that the Inverter series are the most notable popular models of Yamaha generators. Not only are they fuel efficient, they operate quietly and effectively.

Yamaha EF2000iS 2,000 Watt 79cc OHV 4-Stroke Gas Powered Portable Inverter Generator (Non-CARB Compliant)

Yamaha EF2000iS 2,000 Watt 79cc OHV 4-Stroke Gas Powered Portable Inverter Generator (Non-CARB Compliant) Review

I have had this for about a month. This is a very high quality unit, nicely designed. I chose it over the Honda Eu2000i because it has a fuel gage and is a hair lighter (2 pounds), and liked the styling better. Specs are so close it's a tie... the Yamaha unit specs a bit quieter in "eco" throttle but the Honda specs a bit quieter at full power. Prior to this purchase I had bought a Honeywell inverter generator (a much less expensive Chinese-made knock-off) from Costco which I returned, because I was unimpressed with the Honeywell unit's quality and noise level. While the price difference is major, you get what you pay for in this case. Anyone looking at the cheaper knock-offs should really consider that a 5db increase in noise level is about twice as loud, the way humans perceive it.

The most impressive thing about this unit is how quiet it is. Even at full engine speed you can stand about 6 feet away and have a normal conversation without raising your voice, or talk on a cell phone without undue distraction. It features an "eco" setting which tapers down the engine throttle and noise when full load isn't required. At half-throttle or less, from about 6 feet away it is about half as loud and amazingly quiet. I used it to run a 50-amp 12v battery charger and at full charge level the charger only required the generator to operate at about half-speed, and when the charger tapered down the charge level to under 30-amps the generator became so quiet I literally forgot about it. It is MUCH quieter than my boat's inboard diesel engine, and more efficient than running the main engine just to top off the batteries. I also used it to power a heavy duty 120v grinder and it had no problems supplying the needed power, even on electric motor start-up.

I got this mainly for charging our boat's batteries at anchor but I also wanted the ability to run power tools. The lighter 1000-watt inverter generators could easily handle the charging application but not the more power-hungry tools. Having the extra power also means the eco-throttle will likely kick in earlier and the unit will operate quieter. The number-1 purchase criteria was "quiet" because I don't want to be distracted by incessant noise or be a bad neighbor in anchorages. The Honeywell was not quiet enough in my opinion.

An appeal to other boaters and to campers: Please don't settle for "cheap". Get a better quality inverter-generator unit that's quieter so you minimize noise pollution in get-away places. (Leave your "contractors generator" at home!!!) Also, please be considerate of neighbors and limit running it to times/places you aren't as likely to disturb others... and don't leave your boat or campsite while it runs and runs. We all like our electric conveniences, but if you really need 120v power more or less constantly; you should stay home or get a dock/parking space where you can plug into "the grid". It's rude to disturb others who are trying to get away to find some peace and quiet. If generators are abused it will lead to regulations banning them.

Negative: The unit ships without engine oil, so you need to buy a quart of standard 4-stroke engine oil and fill it. You will also need a funnel, and a pan to catch excess oil. There is no dipstick; you need to fill to the level of the bottom of the filler hole until any more runs out. It uses less than 3/4 quart. I think they should have included the required amount of oil, and a plastic filler container with a spout, marked to show the proper amount of oil to use.
