A couple months ago.. during debate on portable power generators, one
poster stated if I remeber correctly that majority of portable
generators produced modified sine wave power, compairable to quality
of power from cheap inverter ( bad for sensitive electronics)
1. Is this true? IIRC it was one poster who was stating this..
2. If this is true.. what do you look for when buying a generator
that delivers "quality" power that won't fry electronics? I have not
seen any stickers on units for sale that say they're modified sine
(tropical storm/ hurricane season is here!)
You have it all wrong. Generators produce a real sine wave. However...
Inexpensive generators are usually not voltage regulated. There are two
consequences of this; they can wildly fluctuate voltage as the load changes,
and they are usually very noisy (both is waveform and sound.) Either one
can damage sensitive devices.
Six years ago we had a major wind storm that left a few hundred thousand
people without power for up to a week. I know of 5 furnaces that were burnt
out by unregulated generators, but there were thousands of unregulated
generators powering furnaces. So your odds are good, but the price for
being one of the losers is pretty high. Do you feel lucky? Personally I
prefer a good generator; they are safer, quieter, and generally use less
gas. Those are all good things that justify their price.
If they have voltage regulation (or possibly automatic voltage regulation)
they will feature it in their advertising copy, as it is an important and
expensive feature. If they don't mention it, they don't have it.
Sadly, it will probably cost twice as much as an unregulated genny, but you
get other good features as well; such as low noise, etc.
If price is a problem, you might get lucky with a used one. Last year I
bought a small used regulated Kawasaki with only 20 hours on it for $350; it
was about $1,000 new, but apparently the market for used Kawasakis is not
good. (Or you might get one with 1000 hours without an oil change; you have
to be careful.)
You might be able to get a deal on new ones, too. Around
here in Upstate NY, Home Depot has been selling the Generac
7550EXL for about $1K. Seems to be a decent generator - voltage
regulated, has an idle setting that substantially reduces
noise, electric start, pressured oiling, etc. Only other
thing I'd wish for is an oil filter.
The Generac EXL line all have oil filters. EXL is Electric start
Extended Life. The 4000EXL the 7500 EXL and the one you mentioned 7550
EXL, They also come with an extra oil filter , Battery and float charger
and cover. I have a 7500 EXL from Lowes which often has a Transfer
Panel kit giveaway. The models on EXL are similar but Generac badges
each stores unit as unique so they dont have to expose the store to
price wars. So ineffect HD and Lowes carry the same unit plus or minus
a few features but HD will not match a price at Lowes saying it is a
different model when in actuality it is but say a 50 watt higher rating
and different color and extra extension cord, or other giveaway. The
700$ 4000 EXL is nice as is the 7500 EXL which I paid 1250 but got allot
of freebees, Air - Oil filters, plugs, Oil, Charger, and a completly
wired transfer panel , Wire- cable, Plugs , and ccver. Generac makes
their own steel sleeve, pressurised , oil filtered , electric start
motor and is owned by Briggs & Stratton.
Remember to run it with a mild load of 220 in no longer than 6 mo
intervals or the Gen Head can loose residual field magnitism and need
complicated " Flashing " to Re -magnitise the Gen Head magnetic field.
Bzzzt. Sorry, but your advice is as inaccurate as usual. I have
a 7550EXL currently sitting in my garage, and I can tell you
with 100% certainty that the engine does not have an oil
filter, and neither does it come with a cover.
Got any more uninformed statements to make?
USER . You either dont have an EXL , got screwed, or dont know how to
look at a motor , or dont know what an oil filter is.
EXL models have oil filters, you stupid Bozo.
As I said " Extras " define store model differences, a cover is an "
This exchange reminded me of yet another thing Uncle Schlomo told me...
"If someone comes up to you with a deck of playing cards and offers to
bet you $20 that he can make the Jack of Spades rise up out of the deck
and spit prune juice in your eye" - - - - "Don't bet him, you'll be $20
poorer with an eye full of prune juice."
I'm definitely not taking sides, but I can't wait to see the outcome...

"As long as there are final exams, there will be prayer in public
I'm with you Jeff. This will probably resolve itself with something along
the lines of;
"The older model XYZ123 HAS an oil filter. However the new model (which has
a different design of engine?), also labelled XYZ123 does NOT HAVE a .......
etc. etc. ".
But is it not worrying when people jump so quickly to fixed conclusions?
It's rather like saying "Some posters to this news group don't know to
properly discuss, debate accept or refute information. Therefore all posters
to this news group aware incapable of doing so!
Stay tuned; we may learn something. Cheers.
I have the 7550 exl...There is an oil filter.(Yes an oi
filter)...panel...lots of cords and much more...Id like to hear som
ideas on quietness for this model, esp for camping scenarios..
Thinking about a sound solution car muffler and a insulated - vente
quiet box.....Biggest downfall is weight and traversability.

USER you the looser
Generac model 1470 at HD the 7550 comes with an oil filter, go check
the Generac site Bozo, Are you so stupid you cant see it in plain view,
or to fat to bend over and look. You better learn to use your equipment
USER-Looser. Mr A
You mean the one that I have in my garage, as opposed to the
one you don't have?
I'm rather curious about what you'd have to say if I posted
photos of each side of the engine, and have you try to point
out where you think the oil filter is. And then see if
you even bother to respond, when you can't find it. :-)
