Off Grid Saviour
Have had this generator for 3 years as my alternative power source when free camping in our 22' caravan. We have been on the road for the past 5 years and have other generators to compare to.
Apart from regular servicing, which is really an oil change and air filter clean, i have not had a single problem with this generator. Has been used in the recent heatwave to run the air con on our van which it does with no problems. Has run continuously for 10 hrs (apart from stoppages to refuel) with faultless service.
Starts first pull everytime and...is reasonably quiet for a larger generator. Comparable to the similar sized honda. Currently has 258 hours of use. I have fitted an hour meter to monitor use for servicing purposes. I have no hesitation in recommending this generator.
Purchased in September 2015 for $1,899.00.
not as good as I'd expect for a Jap machine
This is the second EF2400is Ive had. The first one after three years, the ECU failed. It was always an easy machine to start, usually first pull, but anyway I decided to stay with the brand...bought another one....and again the ECU failed..!!...after a few years..
Before the Yamaha I had a Honda...not once did i have a problem with it. It always started first time, and not once did it ever let me down. ...Im going back to Honda. You might be ranting how good your Yamaha is now.....but it will stop working sooner or later.....Honda's seem to go on for ever..!!
Purchased in August 2015 for $2,200.00.
I tested my caravan AC (older Ibis) on both Honda and Yamaha 2 generators. No go. Bought a cheapy 4.4kw - what a mistake, it would not power anything over 1600w. Bought the Yamaha iS 2400 and have not looked back. Runs AC, washing machine (300w) and battery charger (240w) at the same time. No Eco switch needed - it's in full time Eco as the oversized engine (171cc) has enough grunt to power up under full load. a bit heavy at 32kg, but that's not surprising with the large, easy-working engine. Starts easy, and I like the fuel gauge, so I can refill when it suits me.
Starts first time every time.
I bought my generator back in December from Totals tools and I have set it up on a fridge slide in the ute canopy. We are basically full time travellers and I have been using this genny in conjunction with the gas cooking to boil the kettle, cook toast and use the frying pan. In the 3 months we have owned it we have not had any issues with it. The main reason we bought it was to run the aircon which we haven't had to yet but we won't have a problem as it runs all the other appliances with ease. A bit heavy but on the fridge slide I don't have to man handle it. Runs super quiet as well.
The perfect Builders tool.
I have just finished a 650 sqm 2 storey home to lock up stage using only the Yamaha 2400 as my power supply. Permanent power is now connected and the money saved installing temp power almost paid for the inverter. Simply brilliant and a must have tool for remote building.
Perfect caravan genny!
Weighed up the options for a long time for home backup power and for our caravan and ended up with 2 prefered options. The Honda EU20i and the Yamy EF2400is. Decided on the Yamy for a few reasons. Extra power, fuel gauge and fuel tap. Our air cond is an old AirCommand Wren....no soft start...genny roars a bit on start up but purrs 5 seconds later. AirCommand weren't confident the honda EU20i would handle the hard start and that decided it for me. Yammy is heavier and bulkier but is a powerful unit. As far as the noise goes there is no such thi...ng as a quiet genny. Ive heard both units and they are bearable 10m away. Better 25m away or further but long leads arent a good idea either. You get used to the constant hum. I would be surprised if there is a caravan aircond the yammy couldn't handle. Definately recommend the Yammy EF2400is!
Very quiet and plenty of power
I needed to upgrade from my current generator a Honda eu10i as I've changed from camping to caravaning. So I did the compare the pair, on one hand the Honda eu20i & on the other the Yamaha ef2400is.
The Honda eu20i would have been the same as the eu10i in quality and a great unit, The Yamaha seem to have the extra punch alowing for the reducution in power output in hotter/colder climate or altitude.
I've owned a 4stroke Yamaha outboard engine for 9 years and I'm absolutely impressed with the finish, fuel efficiency & decibels, so I sold my ...
Excellent product, easy to start, and ultra reliable
I bought this genny tossing up between the Honda 2kw.
Was used to power the aircon in my caravan. But, unlike some competitors, I could run the Microwave AND aircon simultaneously!
It starts easily, runs a hell of a long time on a tank of fuel, and would be perfect for caravans where you have the room, especially larger vans
It's only fault is size and weight. It's big, heavy, and cumbersome. I could slog it around myself, but it's really a 2 person lift, and not something you'd want to toss around a camp sight without need.
Otherwise, if you were looking for a home backup genny, or one fixed into a larger van, it was bulletproof.
Quality Yamaha engineering, would gladly recommend to anyone.
EF2400IS - Great Geni
This generator is great. Quiet and efficient and starts real easerly. We bought this unit after researcing and comparing against the 20i Honda. i found that overall the Yamaha came out on top. If there was one thing i think the Honda had on this unit, it would be the ease of moving it.
Very low noise. Ease of operation.
Hard to move one out.
Questions & Answers
My Stator has gone on my EF2400IS. I need to buy the part but from what i can se they are way to expensive. Do i have to buy genuine?
Would this generator be a good back up generator to an off grid solar system? Can it be wired in for automatic start? Does it have an RCD?
Roz, the Yamaha is2400 does not have electric start. It's a very reliable pull cord start. And it does not have an inbuilt RCD as far as I know. As a camping/caravan power unit, the RCD is inside the caravan. It would certainly make a good backup to a solar/battery off grid system. On a 48v system it could power a 40 amp 48v charger.
I would like to use it for back up heating in power outages in a small bungalow. Can you recommend a simple heater it could power?
The Yamaha 2400is is rated at 2200watts continuous, so any heater of less than this rating would be ok. Look st the power rating in the box or the heater itself. There are a number of small inexpensive two stage ceramic fan heaters available which are around 800/1600, or 1000/2000 watts which will work well with this generator. Any oil column heater rated below 2200 watts would be ok too. Small reverse cycle air conditioners of around 3000watts heating capacity (less than around 1600 watts power usage) will probably work ok too. I say probably there as reverse cycle AC units have motors which have a surge current when the compressor cycles on, which must be less than the 2400 watt surge limit of the 2400is generator. "Soft start" AC units reduce this surge on start up - talk to the people selling ACs if considering this option.
