Solar Energy Backup Power?

[Kiwi John]

set it up in a trailer that way if you dont get hit and a mate does you can
hire it out

 

[Kiwi John]

if it going to be cloudy and youre worried about solar power use a
hybrid system
with a wind genny as well

then you dont have to stand in line to get fuel

 

[Kiwi John]

go to the front of the car most now days have a electric fuel pump

Put in a transfer panel, 6 circuit can be purchased and instaled for
apx 400. Get a voltage regulated dual or tri fuel gen, Ng, propane,
gasolene. www.propane-generators.com has conversions and companies
like Northern tool sell them converted. You just run a piped gas line
outside with Quick Release fitting and use house gas, so you never need
to store fuel. With your electronics you need to research gens. Cheap
unregulated units swing 30v+ from no load to full load with 4% Hz
swings, these will blow sensitive electronics. Govenor regulated swing
4-10% much less than non regulated but still alot. Honda, Yamaha, and
other inverter designs can swing 1%, They do cost 3-5 times that of a
Generac but can also last 10000- 14000 hrs because RPM is load dependant
, a 1800 rpm unit lasts 4x that of 3600 rpm. A HD Generac 4000 EXL is a
good deal at 800$ , converted to Tri fuel for apx 400 more. It is a 3600
RPM unit with electric start, voltage regulation of apx 7% and a
pressure oiled system with filter, it is good for 2-4000 hrs, but LOUD.
Cheap lawnmower engine, unregulated power styled units may do only 250-
400 hrs. DB - sound ratings are important, many units like Generac will
keep a neighborhood awake for a 1/4 mile. Honda and Yamaha have units
you cant hear at 30ft. In generators you realy do get what you pay for.

It gets hot and humid here in south Florida, especially after a good
hurricane. "Waiting until the grid comes back on" can mean weeks. That said,
all of the above things can be great. You forgot to mention a good woman! I
find that helps a lot.

How about the neighbors woman while the old mans out refueling and tweaking his Gen.

Forget the wind generator. The neighbours would never tolerate the noise and
you need a few acres of land to set the ugly thing up on. The controllers
are much more complicated and pricey

 

[Kiwi John]

well im not talking a bloody big tower with a blade that came off a dakota
im talking some thing that will do about 500 watts durring the storms you
have they pretty much go 24 hours a dayeven if they worked 18 thats about
9Kv

and they dont make a lot of sound at all

last thing id want if i was your neighbour was to hear a constsnt swish
but an extention cord passed over the fence would be a godsend

 

[John P . Bengi]

Well the reports I have read differ about the noise. Never recommended for
any city properties at all.

And the few I have seen so far are quite audible at 500-600 metres away.
Especially the small ones that furl out of the wind. Noisiest things. They
would last a few days here without the city damanding them taken down. If a
neighbour of mine had one I would shoot the blades off it or saw the tower
down at night if they wouldn't comply. Like a small helicopter landing in
your backyard.

Other stories report people stopping them after 9 PM because of the noise as
a compromise.

I have some digital film of a few larger 2-3MW units and you wouldn't want
to live within a km of them. I thought it was a jet passing overhead until
it never went away. That was about 200 metres away.

Read some of this. None of them are acceptable

Relatively quiet, you say. Gas mowers are far from quiet... try in the
range of 85 to 95 db's.
Only slightly quieter than your average AC/DC rock concert.

OK, they can throw in a muffler kit.

Forget the noise, a good muffler, soundproofing in the shed and vibration
damping under the unit aren't so difficult to achieve. Manual hookups
aren't a problem, I do it all the time. It's not rocket science to
disconnect the grid before connecting the generator.

Ok, smart guy, explain this: Millions of lawnmowers are used in suburbia
every day. Running a lawnmower-generator during a power crisis is going to
suddenly become a noise issue? I agree with those who say you post things
just to read what you are writing.

Come back when you are sober.

A product that is missing from the marketplace is a
flywheel/pulley/alternator that bolts in place of the blade on a
rotary mower. That would eliminate the duplication of gasoline motors
and provide relatively quiet battery charging for use with a battery
and inverter.

Not exactly what you are looking for, but might help someone in an area
with frequent power outages- how about a riding lawnmower with a generator
built in? Kinda small at 1000w continuous /1500w peak but might be better
than nothing

Interesting idea!

I look forward to the idea when just abt all cars and
trucks are hybrids and can be used as portable power
generators as well as transportation

 

[Kiwi John]

ok I live in an area of Australia where theres no grid power at all so
everything is genny or anything else we can rig up

Back to the lawnmower idea? What you need depends on how many Kilowatts you
want and for how long. If you just want to run your radios for a few hours a
day, go
the battery route. The batteries can be charge either from your auto, or
from a cheap
Chinese generator. You can pick up a 1000 watt unit from ebay for $100.
