Product Q&A

Ask Us a Question
  • Is this a good generator for home power backup?

    Hi and thanks for your question; yes, this brand and this size generator is popular for home backup use, especially if you intend to run quite a few appliances including those with larger power draw such as; washing machines, larger fridge/freezers, pumps, small to medium sized air-conditioners etc. along with all your other smaller household appliances as well. 

    You can either run your required appliances directly from the generator (via extension chords etc.), or speak to an electrician about installing manual transfer switch to your home so the generator then becomes the power backup source to your house. Another option again, is to consider an auto-start generator which can also be connected to your house mains via an electrician; these type of generators will automatically restore power to your home in the event of a blackout, as opposed to manually switching the generator on.

    In all cases, just be sure you know how much power all your appliances you intend to run will draw so you get the right sized generator. Thanks, Steve.

  • 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!     

  • Along with running fridges, water pumps, lights etc, is this generator also fine to power up wifi, tv, charge laptops / phones etc?

    Hi, this generator is fitted with an AVR (Automatic Voltage Regulator), meaning it reduces the voltage fluctuation to +/- 2.5%, making it suitable to run all your domestic appliances, including the items you have listed. The Yamaha EF7200E is our most popular model for household backup power and other models in that 6to 9kVA range fitted with AVR from the likes of DeWalt and Pramac are also very good. Many thanks

  • How is it that this generator has 15Amp outlets, but the generator's power rating is greater than 15Amps? (as 15Amps equates to 3600watts on a 240Volt appliance). Presumably you can get more than 15Amps out of the outlets then?

    Yes, that is correct. A 15 Amp outlet can deliver more power than 15 Amps for a short period, as there is no circuit breaker fitted to the generator as standard. You can briefly pull the full rated power amount of the generator (continuous and maximum) through the 15 Amp outlet.. noting that this is only for a short time - i.e. when you are first starting up an appliance such as a comprossor, drop saw, air conditioner etc. it may draw around 30 Amps (as an example) to start up, and then drop back down to 10 Amps to keep running.  

    However, if your appliance draws more than 15 Amps continuously, it is not recommended you run it for prolonged periods from a 15 Amp outlet, as it is likely to result in overheating issues. It may be prudent to consider re-fitting the outlets to a larger size to fit your continuous power requirement (i.e. 20 Amp, or 32 Amp outlet for example) - this can be configured upon request at extra cost. Thank you.

  • What engine oil should I use with this Generator?

    Hi - the generator requires standard engine oil;  either 10W-30 or 10W-40.

    This is available from any local service station. Many thanks 

  • Hi,I am thinking of this generator as a blackout back up for a water pump and whole house filtration system (mainly UV light). I would place the 1HP waterpump on it's own output, and would it be possible to have a power board on the other with the filtra

    Hi Matthew,

    Thank you for getting in touch.

    Provided you do not exceed the continuous output, and any surges do not go above the max output of the generator, you can certainly set it up how you described.

    If you did exceed the max output the circuit breaker will trip. You'd then need to reset the breaker and remove the excessive load.

  • Can I use this generator to charge my power tool batteries?

    Hi there,

    Charging battery packs is fine from a conventional generator, we'd recommend having a steady load on the generator and don't connect appliances that will cause the load to jump around during charging.


  • would this generator be suitable for food trailer? how does noise compare to a inverter generator?i was looking for something less expensive than inverter generator but still reliable

    Hi There,

    This generator will be significantly noisier than an inverter generator as the entire engine is exposed.

    It will still do the job, but may interfere with trading due to the noise factor.

    Inverter generators do cost more, but they are designed to be quieter and used in applications like this.

  • Hi, would this generator be OK to run a welder such as the Lincoln 180C mig welder?

    Hi There,

    This generator would not be suitable for your welder sorry.

    We would recommend a minimum of 8kVA, though a larger generator would be better suited.
