Back in January this year, I did purchase this generator with the intention of mounting it in a fix location in the RV and having it as a backup and for those days when the washing machine is in use.

So far I have probably used for 20 hours all up and beside the initial “problem“, it has run perfectly fine since…

The Pros:

  • Low fuel consumption
  • Very quiet
  • Easy start
  • Large fuel tank
  • Easy access to oil/spark plug
  • Economy mode

The Cons:

  • No hour meter
  • No way to tell if the overload has tripped
  • Awful manual layout

Because of the small size engine and the Economy mode, you get nearly 20 hours out of one full tank. This is however not the standard situation, unless you bough the generator just to run the LED bedside lamp… It would be wise to take 10 hours as the average run per tank.

Again in the Economy mode, you can hear the birds and at full speed, you can still hold a conversation three metres away from the unit. Sound level is low and good.

Electric key starter with optional remote control and easy recoil for backup..

This generator does come with 13 litre tank, that it is the same size tank as all others good brand 3kW generator on the market. It is a good size tank and has a very large inlet with mesh filter..

Oil change or level check, battery and spark are all easy accessible by mean of small hatches on the sides

I didn’t think much of the Economy mode until I did use the generator while repainting the roof of the RV. In a nutshell what the Economy mode or Smart Throttle does is allowing the engine to run at a specific speed based on the actual load.. If you are for example only using 700 watt the engine will produce only 700 watt instead of the 2800 that can produce at maximum speed.. It does make sense and it does save a truckload of fuel and minimise components wear..

One thing that I can get my head around is, how on earth are you suppose to know the engine running time without an hour meter. That to me is a serious fault, as even most $1000 Chinese generator (I do have one that is 7 years old), do have a $10.00 display with hour meter, Voltage and Amperage, that are the three basic information required by most users!

What they give us instead, is a 12 Volts battery charger plug that, if you have any understanding of the minimum voltage required to charge a 12 volts battery, you quickly realise how useless that is. That, is not a 12 Volt battery charger, but merely a 12 Volts DC output!

Another feature that in my mind could have been better implemented is the over load mode.. Yes it does protect the generator and yes it does lit the red light, but because the engine continue to run undisturbed, unless you are right if front of the generator, there is no way for you to know that the generator has actually stop producing electricity. At least a $4.00 small piezo buzzer could have been implemented with the red light, for the customers like myself, that don’t sit in front of the generator drinking Martini with olive like in most of their advertisement!

Finally the manual.. Oh Jesus… why do we need 8 language and printed in landscape mode.. The best way to describe this is if you try to hold a t-shirt by both end perfectly flat.. It is simply impossible  :D .. If you want to read the manual, you will need a table…

Now that the Pros and Cons are out of the way I would like to offer a couple of easy modifications that I have already performed on my generator to improve on those two very silly shortcoming from Yamaha.

The first one will required the removal of the 12 Volts plug and use the existing hole (it will need to be enlarge a fraction) to insert an hour meter..

As you can see from the above picture the 12 volts battery charger is gone and I can finally see at glance how many hours the engine has been running.

There are six small screws and four larger one to remove the control panel. Don’t worry about as there is nothing to break behind. The 12 volts plug has a white (positive) and a black (negative) wires going to it. Those are the wire you will need to use to plug in your hour meter. You can buy cheap ones on Ebay for as little as $10 dollars..

Finally I connected in parallel with the Overload light the Piezo buzzer mentioned before, so that when the light comes on, if the generator overload, I also have an audible sound to warn me that the generator is actually off. Plenty of room for it, in the back of the panel..

Total cost was short of $15 dollars and I do feel sorry for all this big brand name, when they tell me that I’m getting a great product and then they skimp on important details to save few dollars.. Good news is that if you buy Yamaha or Honda generator around the $5000 dollars, you do get those feature as standard..

Back in January, when I did had to decide between Yamaha and Honda (as 98% of the specs are identical), I went for the Yamaha for three main reason.

All three where not really by choice.. Because of the chosen location in the RV, the Honda would have had the control panel facing the wrong direction..

The second one was that, again to allow for oil changes without having to remove the generator from the vehicle, the Yamaha oil change panel was facing the right direction, (same as the control panel).. The recoil would have been also impossible to operate in the Honda as it would have faced the main engine

Seriously, there are no real difference between these two units, other that with the Yamaha, you get the trolley wheels for free where in the Honda, they are optional (at least they were at the time). So either one you may pick, they are both great generators..

Someone will argue that the Honda does have the Parallel Connection Operation Ports, but frankly I rather pay much less to purchase the $5,200 dollars 6.3kW generator than two $4,200 ($8400 for 2) 6kW combined power.. It just doesn’t make any sense spend that much money for that little power…

Yamaha ES6300iSE (Watt5500,12 Hours per 17 litres) $25.5 dollars per tank or $2.12 dollars per hour of use (current price of $1.5 per litre)

Honda Eu30is x 2 (Watt 5600, 7 hours per 26 litres) $39 dollars per both tanks or $5.57 dollars per hour of use

At the end of the day the Yamaha would cost me $25.5 dollars in fuel where the two Honda would cost $66.84…
