I have a small (2kw) suitcase generator that runs on gas, but doesn't
supply quite enough watts for some uses.
One option is to buy another just like it, except made to run parallel
with the first one, giving 4,000 watts peak and 3,200 watts continuous
But 3,200 is probably more than I need and I'm thinking I could live
with the reduced power output when running on natural gas (which is
piped in to our house) and reap the benefit of not having to store
The Question: Is it realistic to consider a remote gas outlet somewhere
in the yard with a flexible hose that could be connected to the two
To answer your question: No, to the flex hose.
Your best bet it to simply limit your usage during the periods where a
generator is required.
If you use two generators you will either have to synchronize them which
will require complicated and expensive hardware...or completely separate
If you really need more power a 4000 watt generator does not cost much
more than a 2000 watt unit, just get a new one and sell your old one.
natural gas are different systems.
As to two gennies, some can be put in parallel, but again
to check the manual.
Philo had a couple good idea. During power cuts I go
into energy saver mode, and wait it out. What extra power
is so badly needed that it can't wait a few hours?

I think it's the perfect solution for using a portable natural
gas generator. No different than using a gas grill and people have
outdoor gas quick-connect type settups for those. As long as
the installation is done correctly, there isn't anything wrong
with having a gas connection available outside. You could plug
a gas grill in there using it's flex hose and it's A OK.
On the generator side, taking a gas generator and converting
it to nat gas or propane, will result in a generator/appliance,
that is not listed by the appropriate agencies, etc. But
certainly a lot of companies are selling the conversion kits
and a lot of people are doing it. I see tri-fuel conversion
kits, that allow you to switch back and forth or permanent ones.
Given that it's going to be
outside, in an open area, I don't see a lot of risk in it, but
you'll probably hear opinions to the contrary. In which case,
you could buy a portable nat gas generator, but the one's I've
seen cost a lot more than converting one.

Forgot to add, you can't parallel those generators. There is
no way to keep them synchronized. I think what you really mean
is to use one for some loads, the other for other loads. As
long as your doing that via extension cords, that's cool.
But if you really mean to parallel them and use them to feed
the main panel, that's out.

Interesting. I didn't know or expect that. I just looked
at it though and you're right. The Honda EU series allows it.
They are inverter based, which makes sense, since then it's
easy to synchronize because it's independent of the RPMs. Looks
like all you need is a special cable to link them up.
The gennie that I have now, a Honda EU2000, is designed to be paralleled
with another like it. It's quite a popular option among campers
because it offers the ultimate in fuel economy but allows for higher use
when that use is needed. One of those things, pushing 800-1,200 watts
goes 6-7 hours on a gallon of gas for me.
800-1,200 is what our house cruises on. The high figure for when the
furnace and an old refrigerator are running.
From what I have read so far, two EU2000's pushing the same load, will
go maybe 5 hours on a gallon instead of 6.... but I'm still searching
for actual use data.
The attractions of running them on nat gas would be:
- Not getting up at 0200 to fill tanks - although that's probably
a red herring given the availability of six-gallon external
- Not having to store gasoline against a power failure
- Not having to worry about hunting down more gas if/when
the reserve supply runs out.
- Not paying highway tax on the fuel.
The EU2000 served us well during the recent 5-day outage. Our little
gasoline hoard in the garden shed took us through it with
plenty to spare while our neighbor with one of those loud Home Depot
monsters found himself driving an hour and waiting in line to get enough
gas to feed it.
For cooking, we used 16-ounce propane cylinders driving a miniature
grill and a screw-on stove burner.
Do they come with key locks? I'd be nervous about a gas line that was
accessible by juvenile delinqents from the outside. While I expect it's too
technical for most of them, a few special rugrats do learn how to hotwire
cars and perform other "technical" criminal tasks. (-:

I don't think so. It's just that last time I looked, couple years
ago, there were very few companies that offered nat gas portables.
There were a lot more manufacturers that sold propane powered ones
and those were half the price. With either fuel they are very similar,
so I think their thinking is with propane it's portable so you can
use it with a cylinder anywhere. More manufacturers, more choices,
lower price. I guess you could buy one of the propane ones and probably
run it off nat gas too, but then you're still converting something
into something else.
But as I said before, if you have nat gas available, using that
with one of the portable generators, like the OP plans on doing
IMO, is a real good backup power solution. I'd also consider one
of the tri-fuel types that can run on gas, propane or nat gas.
You could get set up with that for less than half what one of
the whole house nat gas generators would cost.
Sure, but check your local codes. In some places the gas device must be
secured in place and flex lines may not be permitted. You can also ru n
a gas grill to make the piping worth while too.
Some generators cannot be run in parallel either so you may have to
split the load.

I'd extend that to almost all typical portable generators used for
backup power. The typical generators
you'd buy at HD, Lowes, etc can't be run in parallel. There is no
way to keep the engines synchronized. So far, the
only ones I've seen that can are the Honda ones EXT was referring
to. And those are *inverter* type, the most expensive ones and
not the typical ones most of us here have. They do it via a
special cable that you need between the generators to keep the
inverters in synch. The inverters decouple the engine speed
entirely, so it's trivial to keep them in synch. If you have a
generator without an inverter, ie the less expensive ones, forget about it.
The thing I was worried about was the open ended concept of
paralleling generators. The origial post didn't make any
qualifications, which might leave some with the impression you
can do that with any generator.
