How To Connect a Backup Generator to a House

Product Q&A

• 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.

• 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  

   

• 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. 

  You can find a Yamaha local service agent by clicking HERE

• 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.

• 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.   

• Whereabouts are the Yamaha service agents located? Thank you.

  Hi Martin, Yamaha has over 200 accredited service agents around the country. The following website link has the full list and you can type in your postcode to find the nearest service agent to you: https://generatoryamaha.com.au/where-to-buy/

• Just to be 100% clear, is it definitely not possible to wire in an Auto Transfer Switch (ATS) or just highly advised against, as it would void warranty?

  Hi Matt, our position is that it is advised against as it will void the manufacturer's warranty.  

  It is an electric start generator, so we are aware of people who configure electric start generators for auto starting capability. 

  However again, we recommend that if you are looking to use a generator for auto start (i.e. with an ATS), then you consider our Auto Start Generator Range HERE.  Thank you.

• Can I connect a power board to this generator so I can run multiple appliances from the board?

  Hi Sue, yes you can connect a power board to run multiple appliances. Just be sure that the sum of the power draw of all your appliances are within the capacity of the generator. Check out our step by step example of how to make sure you get the right sized generator for all your power requirements: Generator Buyers Guide

• 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 arrestor 
  

  You 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. 

• Can I run a 120v 20amp mig welder off of this generator? Specifically the Lincoln Mig Pak 140. If not, then I need a recommendation for a light weight generator?

  Hi there, this is not typically a generator we would recommend to run a welder. Most welders will need at least 4-5 kVA and above. However it is strongly recommended that you contact your welder manufacturer (Lincoln) and get their advice on what size generator best suits your particular welder. This way you can choose a generator that is the lightest possible, but still large enough for your specific welder model. Thanks.   

• Hello I have an existing ATS (automatic transfer switch) all wired up from my existing generator, will I be able to simply connect this generator to my ATS with a little customising or does this generator require a specialised ATS, thanks....!!

  Hi, the Yamaha EF3000ISE is not a '2 wire auto start' generator. This model can't be wired up to an ATS. We do have a auto start range which come with an ATS. You can browse the range here: Auto Start Generators.

• 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.

• If I run a 3000W inverter connected to my house with mains supply switch off can I run my domestic 3 kW solar system as well? Solar system normally needs a supply voltage to activate.

  Hi,

  Thanks very much for the question. 

  It sounds like you have an "On-Grid Roof Top Solar" system installed in your residence. When the grid is down you will not be able to make use of the power from these panels.

  You could use the Yamaha 3000W Inverter Generator, via a 15Amp lead through a Manual Transfer Switch (installed by a Qualified Electrical Contractor) wired directly into your control board for back up during mains failure. 

  Alternativly, you could browse the Auto Start Generator range, which could be configured to switch on automatically when the grid goes down. 

  regards

  Paul

• Can I buy the cover separately?

  Yes - Covers for our Yamaha models can be purchased as a separate item and can be found in our Generator Accessories section here.

• 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.
