Hi there, I'm considering a Yamaha, but have noticed several other 'generic' generator brands for around a third of the price and offer similar specs. What's driving the price difference?
Great question Craig, thank you! Some lesser known brands have their place, really only for people who will use their generator infrequently - in which case you can save some money. Then there are also many cheap brands out there that are a good chance to break down on your first starting attempt!
With Yamaha, firstly - their specs are superior; not only are they the quietest and lightest inverter generators in the market, they are also built to handle more intensive, frequent operation. So with a Yamaha, you know it is going to handle your power demands easily and you can use your unit for multiple applications if required; recreation, home power backup, small business, events etc. It is the premium inverter generator brand in the market.
Secondly, with a Yamaha you get a 4-year warranty (which is much longer than the cheap brands) and you get the support of over 200 accredited service agents around the country. Our experience is that the Yamaha after sales support, servicing and parts support is excellent. You don't get a national service network with the cheap brands.
Hope that help explains the price difference, cheers, Steve!

Looking at yamaha 2800i, noticed its in open frame compared to closed in designs. How does this go for a caravan? Only need it to run AC in the van.
Hi Laurie – great question. The most popular generator models for caravan air-conditioners are the Yamaha EF2400iS and the Yamaha EF2800i. The main difference between the two is that the EF2400iS is the more typical inverter style enclosed generator with sound proofing insulation, meaning its extremely quiet with a noise rating of 54dBA. The EF2800i provides a bit more power, and is in the open frame style (as you pointed out) – which makes it 3kg’s lighter, but also means that it has a higher noise level rating at 60dBA as it doesn’t have the enclosed casing.
Choosing between the two, obviously people first look at their power requirements and opt for a generator which best suits their appliance’s power draw (noting that both the Yamaha EF2400iS and Yamaha EF2800i will run mostly all caravan air con models on the market). Then it comes down to how particular you are with noise level; the Yamaha EF2800i is not considered “loud” like a conventional trade generator, but it is just not as quiet as the EF2400iS, which is super quiet.
The other notable feature of the EF2800i is its 11 litre long range fuel tank; meaning it can run for 17 hours at quarter load. This makes it also popular for backup power at home (running fridges etc.) or for off-grid weekender cabins etc.
Hope that helps - Cheers, Steve.

My product manual for my inverter generator mentions an 'earthing wire / earthing stake' - do I need this?
Hi there, good question. This is mentioned in generator manuals and is a safety feature that will earth the generator. You do have the option to fit an 'earth wire'. Connecting an earth wire and stake is an option available to customer's that purchase a generator.
An earth wire and stake are not supplied with generators that we sell and is application specific. In practice, we do not see customer's do this, especially for inverter generators. It can be something that is implemented for more specialized generators on mining work sites for example...for common applications, it is not common practice to 'earth' the generator with a wire and stake. If you are in doubt, and you have a specialized generator requirement that may need 'earthing', please consult an electrician. Hope that helps.

Hi we are looking at going on the road (nomads) and would like to have a idea on what size generator to run a Caravan A/C and a 185l fridge/freezer? regards Bryan
Hi there, great question. The item that will draw the most power will be your Caravan A/C unit - it would be a good idea for you to contact the manufacturer of your A/C unit, speak to their technical dept. and find out what size generator they recommend for your particular model. We find that the quality Caravan A/C brands such as Dometic, Air Command, Coleman, Denso etc. are very helpful.
In our experience, most Caravan A/C units will require a starting wattage of around 2000 to 3000 watts. So, the most popular generator models to run your Caravan A/C unit are the Yamaha EF2400iS and the Yamaha EF2800I.
Some smaller and newer/more efficient Caravan A/C models can run on the Yamaha EF2000iS. Again, once you have spoken to your A/C manufacturer, you will be best placed to make the call, however we find that most caravan owners will opt for a 2400watt or 2800watt inverter generator model for two reasons: 1) it gives them some extra power capacity for other small appliances if required, and 2) in hotter environments, any generator's capacity is slightly de-rated, so having a generator with slightly more capability than you need can be very useful as the ambient temp gets well into the 30 degrees and above temperatures.
As for your 185L caravan fridge-freezer, this will not draw much power. Most quality upright caravan fridges will only draw around 100 watts (give or take). Thank you.

Is there a way to shut off the petrol supply so I can run the carburetor dry?
Yes, all the Yamaha generators have a fuel valve shutoff (petcock) allowing you to switch off the fuel whilst the generator is operating so the remaining fuel in the carburetor runs dry.
This feature is especially popular if you intend to store your generator in a car, as the petrol fumes ill not permeate through the vehicle thanks to the shutoff valve.

What size generator would handle my Caravan air con? The unit has a nominal cooling capacity of 3.0 kW and run at a frequency of 50 Hz at at all times.
Hi - sizing the right generator for caravan air-conditioning units is a very common question. Firstly, you need to find out the starting (peak) watts of your particular unit; we suggest the best way to do this is to contact the manufacturer of your air-con unit and their technical department will be able to inform you what the exact starting wattage of your model is. For many common air-con manufacturers such as Ibis Air Command, Dometic, Coleman, Mitsubishi etc. the technical departments have tested their range of units against leading portable generator models and can advise what size generator will best do the job.
For the vast majority of popular caravan air-conditioning units, the advised generator size is 2.4kVA to 2.8kVA. The most popular generator model is the Yamaha EF2400iS - it is a great performer for caravan use (including running caravan air-con units) and was rated by Caravan & Motorhome on Tour as the best Caravan Generator. For people that want more power, the Yamaha EF2800i or the Yamaha EF3000iSE are good options.
Just remember that each caravan air-con model is different with slightly different power draw requirements, so doing your research is good practice. Other things to consider is the power draw of any other appliances you also intend to run, along with noting that external factors such as high temperatures (above 30°C) and running long extension leads will slightly de-rate any generator's power capacity. Overall we recommend you size the right generator for your air-con and appliances (by following the steps outlined above), ensuring you also have a bit of power capacity up your sleeve if required. Thanks

Hi, just wondering whether the EF2400is and EF2800i are made in Japan or China? Also, I have a EF2000is bought from you and am wondering if it could be connected with either of the above? Cheers
Hi Andrew, the Yamaha EF2400iS and EF2800i models are made in Japan.
In terms of parallel connection, this is possible for the EF2000iS and the EF2400iS - only these two models in the Yamaha Inverter Generator range have the parallel connection capability. Note that you need to connect two of the same models for it to work...so with your existing Yamaha EF2000iS, you would need to connect it (via the Yamaha Parallel Twin Tech Cables) to another EF2000iS, and this would almost double the power output. You can't connect an EF2000iS with an EF2400iS.
Many thanks.

I'm considering this generator for home backup. How much is it to get an electrician to fit a transfer switch to my home so this generator can power (part) of my house during a blackout?
Hi Anthony, great question. You've certainly identified a popular generator model for home backup power. In terms of cost for an electrician to install a transfer switch to your home, the short answer is; it depends. Not every home install is identical in terms of works required, switch configurations etc.
However, to give you an idea, click HERE for a video from a My Generator customer who had a local electrician install a transfer switch to enable the power supply to their house to be transferred to a portable generator when there is a mains blackout. You can see from the video that the transfer switch install cost was around $600. We would suggest this is a pretty good price, and perhaps indicative of a straightforward install job. We have heard of higher install costs than this for other jobs, usually requiring more configuration works.
My advice would be to get a quote from your local electrician. They can also help advise what size generator best fits your particular home backup requirements. Many thanks!

Good morning, Karen here from Semaphore Caravan Pk Adelaide SA. We are getting ready for our trip around Australia. We would like to know what size Yamaha Generator would best suit us? We have solar panel set up, duel battery among other things.
Hi Karen, to be sure you get the right generator for your Caravan trip, its best to know in a bit more detail exactly what you intend to be running. If you just want the generator as backup option to charge your batteries and a few other small appliances then the most popular generator models are the Yamaha EF1000iS and the Yamaha EF2000iS.
However, if you also want a generator to run appliances with a larger draw such as a Caravan air-conditioner, a microwave, a washing machine, a standard kettle etc. etc. then you may need a larger generator such as the Yamaha EF2200iS, the Yamaha EF2400iS, the Yamaha EF2800i or the Yamaha EF3000iSE. In this instance you would need to know the exact starting and running wattages of these larger appliances to ensure you get the right sized generator for the particular make/model of appliances you have. The starting wattage of these appliances is the most important number to obtain. You can do this by checking the product manual or contacting the manufacturer of the appliance (we find this is the safest/most effective approach).
I hope that helps - if you still need help, please feel free to give us a call on 1300 400 122! Thanks.

I plan to leave the generator outside my long term camp setup, what's your best inverter generator that can handle all weather conditions, especially heavy rain?
Hi there, sounds like a nice set up! The short answer is that electricity and water don’t mix. Whilst we are aware that some people run their inverter gensets in all weather conditions, it is not recommended as safe or best practice for your equipment, as inverter generators do not come with weatherproof outlets as standard.
Ideally, you would somehow shelter your generator from the rain. But just remember that fully enclosing your generator whilst its running is not an option - generators need fresh air intake for the engine to run and they emit carbon dioxide, so they should never be contained. Overall, some rain protection but also room for fresh air intake and fume emission is what you need.
-
How frequently do I have to change the motor oil? Product info says to change it after the first 20hrs, and after this first change?
Hi, after the first oil change, the recommended oil change time frame is every 6 months or 100 hours of use. When in doubt always consult our user manual for recommended maintenance. Thanks!
-
Will this generator run the pump for my house water system?
Hi, that is a tough question to answer without knowing more details about your pump. Water pumps come in a range of sizes and some smaller pumps can run on a small 2000 watt generator, whereas some house pumps would need around 6000 – 8000 watts or more!...electric pumps are notorious for having quite high starting loads. So, you would need to find out the peak load (in Watts) required to start your pump. If you cannot find the starting load from the product manual or data plate, you could contact the manufacturer of your pump, or engage an electrician to take a reading.
Once you have that all important stating load amount for your pump, you can then choose the right sized generator to run your pump.
-
Is the warranty on this product a factory warranty from Yamaha?Â
Yes, you get the full manufacturer’s warranty from Yamaha Australia which would be covered by any local Yamaha service center that works on generators.

How easy is the unit to start? Especially for a female. Can it be converted to a key start?
Hi - The Yamaha Inverter Generator range have very easy recoil start...one small pull for a well functioning generator and it starts. We have sold to many female and elderly customers who do not have any problems.
This EF2800I model cannot be converted to electric start. The next size up in the Yamaha Inverter range, the EF3000iSE comes with electric start. Thank you

I wish to buy a generator for power outages as we are on a rural property that relies on power for water. I have looked at the Supa Swift 3600 inverter and the Yamaha EF2800 inverter. Why you rate the Yamaha above the Supa Swift?
Hi Alan, we would recommend the Yamaha EF2800 above the SupaSwift 3600 model because Yamaha are premium brand, built to handle more regular use and come with a longer, 4 year warranty. The SupaSwift is designed for only light / recreational use.
Using the Yamaha EF2800 for small home backup requirements via a manual transfer switch to your home is a very common application for this model of generator. In fact, you can watch this short video of a customer here using the generator for this exact purpose: https://www.youtube.com/watch?v=573XoF0ZPP4
Many thanks

What is an "inverter" generator?
Hi Alison, and thanks for your question. An inverter is a lightweight microprocessor that converts power from direct current (DC) into alternating current (AC). They are a fairly recent advancement in technology from the older style conventional generators. What it means is that the inverter generators produce very clean power which is required to run sensitive electronic equipment such as laptops, mobile phones, camera equipment etc.
The other benefits of inverter generators are that they are typically much smaller and lighter than standard open frame style generators and tend to operate at very low noise levels (less than 60 decibels). Lastly, they are also very efficient; their engine speed automatically adjusts in accordance with the required load, maximising fuel efficiency.
Overall, they are an extremely popular portable power source for camping, caravanning, DIY tasks, small business uses and home power back up. Inverter generators range from around 1000 watts up to 7000 watts. -
I'm looking at this generator and the eu30iu handi honda, can you please tell me the main differences?
Hi Anita,
We have a comprehnsive article that compares the Honda eu30iu and the Yamaha EF2800i which you will definitely find helpful. This looks at the specs of each unit in detail: please check out the article hereHowever, in summary; both generators have their advantages, but with an extended running time, and a much cheaper price tag, the Yamaha EF2800i comes out on top. Again, please have a look at the comparison article for full details.Many thanks! -
Does the generator engine have an over temperature cut out - I plan to operate it in the Pilbara to run my C.Van AC
Hi Glen,
This generator does not have a high temperature sensor.
The use of the correct weight of oil, keeping the generator in the shade, etc should allow this generator to run without much cause for concern.
-
I plan to place the generator in an enclosure located on rear of my C.Van the enclosure does have vents - will the generator get too hot operating in the enclosure when used for Air Conditioning in the NW of WA
Hi Glen,
We would never recommend running the generator in an enclosed box.
These generators require as much exposure to air as possible to prevent over heating.

G'day guys! I would like to get some advice. I am after a generator for emergency power supply for a water pump, home backup power and DIY projects. Most importantly, I need a reliable generator to run my water pump of 1.7kw with electronic controller.
Hi Marcos - An inverter generator such as this one is going to give you clean, efficient power so you can power any of your sensitive electronic appliances.
The Yamaha 2800i produces a max of 2800w and a rated or continuous output of 2500w. This model also comes with a long-range fuel tank which is handy. The 2800i is the most popular in our Yamaha range for your type of dual purpose application.
The only thing I would point out is that you need to be aware of the starting wattage for the appliances that have electric motors (like power tools and water pumps). The starting wattage can be a lot higher than the running wattage. Sometimes this information isn't always available on the product. You might need to search for this information in the product manual or online, or use a wattage meter to measure this.
You will likely find our Generator Buyer's Guide helpful; this explains in a simple step by step format how to choose the right sized generator for your appliances.
Assuming all the appliances you intend to run (at one time) draw less than 2800w at start up and less than 2500w when running continuous, then the Yamaha 2800i would be a great option.
If you have any further questions, please feel free to contact us on 1300 400 122. Cheers!

Looking for a generator as home back up when power goes out. Maybe for work around property. We live in a rural location, so needs to run house watertank system and fridge, plus some lights. Will the unit suffice?
Hi Philip, for your type of dual purpose use, the Yamaha EF2800i is a very popular generator. To ensure this unit would be able fulfil your requirements during a power outage and for work around your property, we would recommend that you find out the exact starting and running wattages of all your appliances you intend to run. This information can be found on the product data plate, within the product manual or from the manufacturer of the product.
It would then be a good idea to refer to our Generator Buyer's Guide which explains in a simple step by step format how to choose the right sized generator for your appliances.
Assuming the Yamaha EF2800i can power all your appliances, then it would be a great choice; it is an inverter generator which produces clean power so you can run any electronic equipment, it can run for 17hours at quarter load before needing refuelling (making it great for home backup use) and is easy to move around as it only weighs 29 kilos.

Do you guys have some general tips for generator maintenance? Ta
Hi there - good question, yes, we do! Firstly, as a safety note, always stop the engine and let the generator cool down before starting any maintenance work. The five main general tips are;
1. Replace engine oil
2. Check spark plug, replace if necessary
3. Check fuel level and ensure it is fresh fuel (fuel left for a long time can go "off")
4. Check air filter, replace if necessary
5. Clean muffler cover and check spark arrestorYou can also check out this helpful video on generator maintenance tips.
For further maintenance help, you should take your generator to a small engine specialist or an accredited generator service technician.

I am told by my electrician that to wire this into my home - the generator must not have a "centre tap" - Can you advise if this has or hasn't?
Hi, these portable generators don’t have a centre tap.
Many thanks.

I am buying a Yamaha Inverter Generator from you. If I plan to not run it for a period of 4-5 months, so should I just use a fuel stabilizer?
Yes, a good fuel stabiliser will keep your fuel fresh during periods when you are not using your generator and in your case this should be fine.
Other good practice recommendations are:
- Drain the excess fuel in the carburettor after use. All Yamaha generators have a fuel shut off valve (petcock) that you can switch off while the generator is running to use the residual fuel and ensure it does not sit in the carburettor
- Start up your generator every few months for a short period to lubricate internal parts of the unit and even apply a small load to the generator ensure everything is in working order for when you need it next.
Customer Reviews
Excellent product for Home back-up power supply Review by GrantPurchased a few years back from MyGenerator for a home b/up power supply during storm season in QLD. Neighbours very jealous during power blackout. Minutes to set up via transfer switch (Electrician Install) and runs everything we need (TV's, Internet, 2 x Fridges, ceiling fans, LED Lights) even a small A/C unit in kid's bedroom all at once. Powerful little unit. Will run for ages on a tank of fuel. Auto throttle response feature is fantastic and will ramp up or down depending on appliance load.(Posted on 15 November 2022)
