Hybrid Car – More Fun with Less Gas

Honda "EU" Series: Still need to consider fuel/power?

From other threads, I gather that with most generators using one whose capacity
exceeds the load by any significant amount will result in much more gasoline
used per hour of output.

But the Hondas seem to have an automatic throttle feature that cuts back the
power when the load is less.

My kneejerk reaction, if faced with a supposed requirement of 2kw is to get a
3kw generator just on general principles - and the feeling that I probably don't
have as good a handle on the requirements as I think I do.

So, bottom line: will using an EU3000 when the load really is only 2000 consume
significantly more fuel than using an EU2000?

    Actually, an EU 2000 is not good for 2000 watts continuously (only rated for
1600 VA continuous ).  You did not pick an extreme enough example to properly
illustrate the point.  The more common example is a 6 KW genny that is running a
refrigerator and a couple light bulbs for a total load of something under 1 KW.
That 6KW genny with (probably) a B&S engine will drink up to 1 gallon an hour,
while the EU2000 would run that load for several hours on that same gallon of
gas.   I have a 4 KW Natural gas fueled Onan connected to my house through a
transfer panel.  If the only load is my 'fridge, it is much cheaper to drag out
my EU2000 for the job.

     By the way, rather than buying the EU3000, consider 2 EU2000s.  That gives
you the option of tailoring your capacity to the load.; running two of them in
parallel for large loads, or just one for smaller loads.

Good idea. An Eu2000 can be purchased in Michigan for 850 USD. The
cheapest I found a 3000 was about $800

And you can pull start the EU 2000's with one for each hand. The 3000
will electric start....

Hey Vaughn,  How much racket does the 4kw Onan make compared with the
eu2000?

I need a genny about that size that will run propane to replace my
eu-2000. Any thoughts ?

     Mine is in a factory-made steel outside enclosure.  It makes enough noise
that I would not want it pad-mounted directly outside my living room window.  It
makes a Harley-Davidson exhaust rumble plus a good bit of fan noise.   I ended
up putting mine 20 feet away from the house surrounded by a tight/heavy wooden
fence with a ducted air inlet.  Now I can hear a reasuring low rumble inside the
house and I doubt if my neighbors hear anything.


     There is a company out there that sells factory-blessed tri-fueled versions
of the Yamaha generator line, or you can buy kits to convert a wide variety of
generators to propane.
