We are in the process of buying a 2010 Winnebago Esperance. Which inverter generator do you think would be best for us. I'm considering the Yamaha EF2000IS. We live in Tasmania but will be travelling to the mainland next year.I'd recommend a Yamaha generator. Yamaha generators come backed with a 4 year manufacturer warranty and have over 200 approved service agents around the country.The next step is to find out what size you require. This depends on the number and type of appliances you intend to run off the generator. Most RV and caravan owners run the majority of appliances off their auxiliary batteries while stationary. When the batteries run low you can charge them back up using the generator and a battery charger. The Yamaha EF2000IS is very popular for this.If you intend to run appliances that draw a lot more power (especially at start up) like air conditioners, microwaves, kettles or toasters, then you might need a generator with a larger power output. Perhaps the Yamaha EF2400iS which is great for running caravan air-con units. For even more power, the next step up is the Yamaha EF2800i which has extended run time.We have a guide that shows you how to calculate the wattage for different appliances here: https://www.mygenerator.com.au/generators-buyers-guide/Regards,Steve

Hello, looking for a reliable generator with invertor...its for camping, needs to be quiet. Would be good if you can recommend?Hi Graeme, we'd recommend a Yamaha Inverter Generator if you are looking for a reliable, good quality inverter generator, 4 year warranty and with nationwide service agent support. Yamaha are the lightest and quietest inverter generators in the market and extremely popular for camping/camper trailers/caravans.The size of the generator would depend on the type/qty of appliances you intend to run off it. You'll need to know how much power your appliances draw to make sure you get the right size, but as a guide the following will help you:Yamaha 1000w Generator: ultra light, very popular for charging camping battery packs via a battery charger and for running a few small appliances; laptop, phone, TV, lights, small fridge etc.Yamaha 2000w Generator: extremely fuel efficient, also great for charging battery packs and running a few more appliances or items with greater draw such as fridges or smaller air-conditioners.Yamaha 2200w Generator: the latest and greatest from Yamaha.

Hey, I am looking for a generator to run some 150w LED flood lights. They will be used to light up a playing field outdoors. I am looking for the quietest solution. How many lights could a Yamaha 2000 power? Would this generator be the best option?Hi Sam - The Yamaha 2000w generator has a rated or continuous output of 1600w (with a max of 2000w). This means it could run 10 x 150w lights continuously. Yamaha generators are the quietest in their class and come backed with a 4 year domestic warranty + over 200 approved service agents across the country.Obvisouly if you want to run more lights, you will need to get a bigger generator with more capacity. You can check out the full Yamaha Range, which has models up to 6300 watts max.Cheers!
-
With the TwinTech option, are both generators required to be the exact same? For example two EF2400iS?
Yes,
You can connect two 2000W Yamaha Inverter Generators and increase the peak output to 3600 watts and continuous output of 3000 watts.
You can connect two 2400W Yamaha Inverter Generators and increase the peak output to the peak output to 4300 watts and continuous output of 3800 watts.

Will this generator be enough to run my camping equipment? I have a fridge, lights battery charger and perhaps will have some other small appliances like phone and laptop.
G'Day - these are very common appliances for camping and usually a 2000 watt inverter generator will be fine...however, just to be sure, you need to determine the amount of power required to not only run the appliances you wish to use, but also the power required to start them (particularly for appliances like fridges with a motor). For many appliances, the starting output requirement can be up to three times (or more) greater than the continuous running power needed. The exact starting and running wattage for your appliances can be found within the product manual or on the appliance data plate. We have a simple step by step guide to take you through what size generator you need right here: https://www.mygenerator.com.au/generators-buyers-guide/ Take a look at guide and just to be certain you can determine whether 2000 watts will be enough to run all your camping appliances.
Lastly, both 1000watt and 2000watt generator models are very popular and suitable for charging your camping battery packs, however just me sure to use a battery charger between the generator and your battery packs, as this will appropriately regulate the charge.
Thanks.

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!

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.

I have a caravan with an Air Command Ibis 3 air conditioning unit. The manual indicates the Power Input as 1300W for cooling and 1210W for heating. It states the Rated Capacity as 3100W for cooling and 2700W for heating. Would the Yamaha 2000w do the job?
Hi, great question!
This a very common inquiry here at My Generator. The Dometic Air Command Ibis MK3 has been in production for several years with various versions of this model requiring different size generators to start. We know that the majority of the Ibis MK3's out there can be started and run with a quality inverter generator with a peak output of 2200W. The Briggs & Stratton (link)2200W is one of our most popular generators for this air conditioner. If you want to be 100% sure of starting and running the Ibis MK3 then look no further, then the Yamaha EF2200IS inverter generator.
The Yamaha EF2200IS Inverter Generator has a unique boost feature that is ideal for starting all caravan rooftop air conditioners. The boost feature allows the Yamaha to handle a short overload whereas other inverter generators will cut out when under similar demand.
In reference to your question about Rated Capacity (3100W), this is simply the rating of the compressor output and can be used as a size guide but should not be relied upon to size the starting requirements of the Air Conditioner.
Other great options for all roof top caravan air conditioners are the Yamaha EF2400IS and Cromtech 2400W Inverter Generators. To make the decision easier please refer to our Air Conditioner / Generator Sizing Table - displayed in the Product Description of each caravan air conditioner.
-
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.
-
Will this 2000w model run my 240v/ 40amp DC battery charger plus a 50 Waeco liter fridge? thanks
Hi - a 2000 watt generator is very likely to be enough to charge your batteries via your charger, particularly if you are talking about battery packs for camping/recreation; just double check the specs on your particular battery system to see what the required draw is. This model generator is very popular for recharging battery packs for caravan/motorhome/camping uses. We also recommend that you use a battery charger between the generator and your battery packs to ensure regulated charging.
A 50L Waeco fridge will draw less than 100 watts so the generator will have no problems keeping your fridge running. Cheers!

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.
-
I am looking at the Yamaha 2kw to power a 1.6kw Window Air conditioner on a boat. Will the Yamaha run it?
If 1.6kw is the load required at peak to start the A/C, then this Yamaha generator will be fine to run it. Just be sure to check that this is in fact the peak load - you can sometimes find this information on the A/C data plate or within the product manual, but often you'll need to contact the A/C manufacturer, speak to their technical dept. and they can tell you how much power at start up your particular A/C model will require.
The Yamaha EF2000iS inverter generator is suitable for some smaller sized A/C units in boats, caravans and motorhomes. But for many caravan/boating A/C units, the peak wattage requirement is more than 2000 watts - therefore the Yamaha EF2200IS or EF2400IS inverter generator model is the most popular for Air Conditioners: the boost feature of the EF2200iS and the larger engine and greater output in the Yamaha 2400 generator, respectively suits most caravan A/C units on the market.
-
Hi, does the Yamaha 2000 inverter generator warranty cover parts and labor for 4 years? It's for camping use, not commercial. Thanks
Hello - thank you for your query. Yes, all Yamaha Generators have a four year consumer warranty which would cover recreational/camping use. The owner's manual lists the full details of the warranty which you can download on the product page on our site.
-
Hi, Can the Yamaha 2000w generator power a desktop PC? If yes, then; A) How many desktop can it run? (Note-these PCs will share 1 monitor). B) How long will the power last to run x number of PCs? C) Once the generator runs out, what is the next solution?
Hi - firstly, yes the Yamaha EF2400iS can power a desktop PC. It is an 'inverter generator' meaning it provides pure sine wave power; this is a clean type of power that is suitable to run sensitive electronic equipment, like your PC and monitor.
The Yamaha EF2400iS provides a continuous power output of 2000 watts. So it depends on how much power your particular PC’s draw. A standard PC will only draw around a few hundred watts (give or take) – so once you find out how much your particular PC models draw, then you will know how many you can run at any one time from the Yamaha EF24000iS.
For your type of requirement, you may want to look at a UPS (uninterruptible power supply) device - it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries. A backup generator can then provide power to the UPS after the UPS runs out of its initial power. Sizing and type of generator to backup a UPS would best be advised by an electrician, who would insall the UPS.
-
I am interested in the Yamaha 2000 watt, but wondering if there is an option to fit a larger fuel tank, to extend the run time?
Thanks for your question; The manufacturers do not recommend any extended fuel tank be fitted to their generators, as doing this would void the warranty. Addtionally, for this type of inverter generator, it is recommended that after running a full tank of fuel, the generator should be shutdown to cool briefly, then oil checked/added if required before running again.
As an alternative inverter generator which provides longer run time, you can check out the Yamaha EF2800I which has a run time of 17hours at quarter load.

Hello, I need to run 2 wet vaccum cleaners: both require 8 amps max draw, then 4.5 amps running. Also I want to run a steamer which says it takes 1500 watts to start. I thinking of getting this generator my mobile detailing business.
G'Day Serge - using the simple formula of: Starting Amps x Volts = Watts, means that your 8amp vacuum cleaners at 240volts will draw 1920 watts at start up, and then drop to 1080 watts running. So, if you were to use your vacuums or your steamer one appliance at a time, then this generator would be fine.
However, if you wanted to use both vacuums at once, or with the steamer as well, you would need a larger generator. If this was the case and you still required an inverter generator, then another option would be the Yamaha EF6300iS, which is a popular model for mobile business uses requiring multiple appliances running at once.
-
Please clarify if the DC charger facility can be used at the same time as the 240AC is being used? The manual is a little confusing regarding this.
Hi - yes, simultaneous use of the AC and DC power is possible, but wattage should not exceed the rated output.
It should also be noted that the DC charge from the generator is not regulated and is mostly designed for 'just in case' situations, i.e. your flat car battery needs a short trickle charge. For full charging of your batteries, you should always use a quality battery charger which connects between the AC output on the generator and your batteries - this will ensure safe and efficient charging of your batteries.
Thanks.
-
Can I charge my battery pack from the generator?
Hi Adam, and thanks for your question; in short, yes you can. The Yamaha EF2200iS, EF2000iS and EF1000iS units come with DC outlets and 12V charging cables and are popular models to charge battery packs. However, it is strongly recommended that you use a battery charger to charge your battery pack - the DC charge from the generator is not regulated, and so it is much safer and effective to connect a battery charger to your generator, and then the charger to your battery pack to charge up.
The charging cables can be used directly to provide a small trickle for a short period of time in situations such as needing to start a car battery...but once again, for charging your battery packs, ensure you connect a suitable battery charger between the generator and your batteries.

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 just ordered the Yamaha 2000 generator. What type of oil do you recommend? Can I buy the oil anywhere?
Hi and thank you for your order. The oil you require is 10W-30 or 10W-40 as per the product manual. This can be purchased at any service station. Enjoy the new purchase! :)
-
G'Day - which 2000w genny is better, the Honda or the Yamaha?
Hi and thanks for visiting our My Generator site: both the Honda and Yamaha 2000w inverter generators are great products and they both come with 4 year warranties and national approved service networks. However, when it comes to splitting the two units and comparing the specs, Yamaha just comes out on top as being slightly lighter, quieter and more fuel efficient. For more details you can check out our article for an in-depth comparison: Yamaha vs Honda 2000w generator.
It’s also worth noting that the Yamaha comes with 12V DC cables as standard, whereas the Honda doesn’t, and the Yamaha has a fuel shut off valvle enabling you to drain the residual fuel from the carburettor, which again, the Honda model does not have.
-
G'Day, is there a way to shut off the petrol supply so I can run the carborator dry? Have had issues with this in the past on different gensets.
Hi and thanks for your question - the Yamaha range has a fuel shut off switch which is independent to the on/off knob. This means that you can turn off the fuel line when the unit is still in operation, enabling you to use up the remaining fuel from the carburettor. Very helpful if you intend to store the generator away for a while before using again.
-
Can I use the Yamaha EF2000iS to provide temporary portable power to my home refrigerator or freezer in an emergency and to run some lights? If not, what is the best portable generator that can?
Hi Greg - the Yamaha EF2000iS is very suited to running the appliances you have listed. It is our most popular inverter generator and used by many of our customers for backup power, as well as recreation or small business requirements. To be certain this model has the capacity to run your fridge, freezer and lights, you first need to know the exact wattage required to run your appliances (both starting and running wattages), this can be found on the product data plate or within the product manual. This will help you determine whether a 2000 watt generator will be suitable for your needs.
Once you have the wattage information for your appliances, we recommend you follow our simple step by step buyers guide which will help you find the right size generator for your appliances.

We would recommend that you refer to our Generator Buyers Guide which provides a simple step by step guide to help you chose the right size generator for all your appliances.
The Yamaha EF2000iS is a great little generator and while most of customers use it for recreational purposes, many happy customers also use it for smaller to medium tools as well. Again, it just depends how much your tools draw and how many of them you want to run at the same time - find out that information, follow our Buyer's Guide and you'll be sure to get the right sized genset!

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.

Looking at buying a new caravan, and generator. Never had a geni before. A number of caravan vendors have suggested buying a geni larger than the 2kVA as the new air cons can require more than 2kVA, I would appreciate your advice on this?
Hi there - yes, this is a very common question. The best generator for Caravan Air Conditioners is the Yamaha EF2400iS - it will handle the start up load of Caravan Air Conditioner units.
As you mention, most Caravan Air Con units will require more than 2kVA at start up. Some 2kVA generators will run some Caravan Air Con units, however we find that when the outside temperature increases, 2kVA generators will struggle with the Air Con start up loads (as every generator loses power capacity in hotter temps).
So, for caravan Air Con units, we recommend the Yamaha EF2400iS.

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.

We have a 1979 Bedford bus-motorhome. We plan to travel around Aust, and we have a 2kva generator. What Aircon do you recommend? Bus is 10 metres long. Cheers
Lucky you mate! This is an easy recommendation: with your 2kVA (2000 watt) generator and size of your RV, we would certainly recommend the Dometic Harrier Roof-top Inverter Air Conditioner. The will easily start and run from your sizzed generator and the size of this A/C model will suit your larger type of RV.
Many thanks, and happy travels!

Sean, can you connect two of the EF2000iS generators and make a 4000 watt generator?
Yes you can. The Parallel Kit is an optional extra and with it you can connect two of the Yamaha EF2000iS units to almost double the power output at peak, and provide 3000 watts of continuous power. Look for the kit under the Accessories list on the Yamaha EF2000iS product page. 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.
