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.
Will the Yamaha 2400 investor genset run my Heron 3 airconditioner? Regards Mr Pieter Lips
Research says yes easily even with a 2000. My experience doesn’t cover caravan A/Cs. The Yamaha 2400 will run a whole house lighting system, ceiling fans, media and refrigeration. On top of that it won’t run any of our A/Cs, stoves or toasters. Providing the refrigerator is not on a compressor cycle it will even run a microwave if set at a lower power rating. In power blackouts we live very comfortably.
Pieter, it should run the Heron 3 no problems. It runs my 10 year old roof mounted Ibis air conditioner, PLUS a 300watt caravan washing machine at the same time. Together they make quite a big load, since that Ibis has no soft - start technology like some more modern AC units, and the washing machine puts a surge load on the generator each time the motor reverses direction (constantly). The oversized 171cc engine has plenty of torque to overcome short surge loads that can defeat smaller engined units. My sister has a fire fighting water pump on her farm which uses the same Yamaha engine (called an MZ175 for that use). It needs to start easily, and it does. It powers a water pump with a couple of 1 inch (25mm) fire hoses.
I would like to know why my Yamaha 2400is gen keeps hunting instead of running smoothly?
what are you powering up is the first q. next thing is make sure what ever you are running is turned to max other wise the items you are powering may be cutting in and out instead of continuously running, this may be your problem. hope this helps ron webb
My 1kva Honda Inverter gene would hunt with a 'cheap' battery charger... needless to say, it died after 3 years and the place I bought it from said the 4 year warranty didn't cover 'use' of the generator. I bought a Yamaha and CTEK battery charger and all is well. Hunting will wear the generator prematurely.
The answer is to take the air cleaner and little bracket off , drain fuel out of carny by a little screw with Spring behind , out , let fuel out , put screw back in , start motor , then have a tin of good carby cleaner , spray with nossle on It , into carby and onto outlets until you hear the motor run smooth , put the air cleaner back on and you won't have anymore issues with it until the dirty fuel gums it up again , so keep the carby cleaner nearby .
