how do I "hook up" a 7500 watt portable generator - Page 2

 

I asume ekryder- philkryder one in the same, the Honda is a superior
machine in every way, why are you considering a Generac 7500.

 Have you considered a conversion of your honda,
www.propane-generators.com    they even have Tri fuel. Costs are cheap.  

 The Generacs cilinder head needs retorqing at 100 hrs and may not give
as stable a V as the Honda, my swing is 5V+. Ive run it at 7000 W . with
resistance heat, but who knows on surge.

 A Generac 4000exl was tested by Consumer Reports and failed on the load
and surge.

 You may not need a transfer panel but to balance loads 2 watt meters
help, one on each leg, V meters let you monitor V , the generac will
drop to 117?? under full load, and Hz lowers, Maybe your Honda is better
than that.
Meters let you know what is going on. Even generator speed needs
adjusting periodicaly.

 You have a 6000w now and want 7500w  Forget surge ratings , they are
not standardised.

 You need to hear a generac, My neighbors are far, the noise bothers ME
and I like loud music, and am a musician. Generac developes higher watts
for one good reason, it is not muffled much.

 You want to sell it after 1000 hrs, for what 200$, I have one with 9
hrs on it Ill sell you cheap, I want a Honda EU 2000.

 To get an idea of motor life there are EPA ratings on the motor for
different class and designs, 500- 1000 hrs as an example. The ratings
are for when the motor starts to pollute logicly when the rings are
allowing oil to burn.

 Before you buy a generac listen to one and test it, load it to
6500-7000 watts with resistance heat and kick on a circular saw.

 Whatever unit you run a synthetic like mobil 1  5-30 will make it last
much longer.

 

Thanks for all the help -

We have the volt and watt meters and will use them.
Again, I will try to ask, "How do we use the recepticles on the unit to
avoid tripping breakers during surge load?"

Regarding the other points:

Can you tell me where to get the EPA RATINGS?

Regarding the noise -
It is not an issue in this installation.

One other reason for the higher output may be the larger engine size.
The Honda is less than 400 cc.

Here are the ratings which may be inflated.

Automatic Voltage Regulator     Standard
Power Single-Phase     ---
Maximum Output     13,500 watts
Continous Output     7,500 watts
Load Amperage at 120 volts     ---
Maximum Load     112.5 Amps
Continous Load     62.5 Amps
Load Amperage at 240 volts     ---
Maximum Load     56.25 Amps
Continous Load     31.25 Amps
Sound Level @ 23 ft(7 m) at full load     71 dB(A) <<<<<<<<<<

Yes, I agree - we are buying the Generac because it is less than half
the cost and is tri-fuel.
Also, we've had seven (7) of these Honda units since 1994 - they wear
out as well.
The prices have gone up and they break too.
We are ready to try something else at a lower price.
The 25% increase in CONTINUOUS (not surge) rating is a bonus.

As a comparison - If we can run 1000 hours and sell it for $200, we
will be paying about $1.50 per hour for capital costs.

The Honda would have to provide 2000 hours and sell for $600 to achieve
the same cost per hour.

Let's see, the rating of the generator is more than the rating of its
main outlet. That is suggestive that the rating is not an indicator of
what you can really get out of the generator under realistic use
(powering the house). My guess is that the generator cannot
continuously produce its highest rated power, that the rating is BS,
and the outlets are made so that the limit is never realistically
reached. Probably similar to "6 hp" 110V compressors etc.

Well Ive pulled 7000-7200 continous, I do it as my 6 mo testing. I use
240v electric heaters

 

 Do you really think you will pull 13500 watts or trip a breaker

 Look at the sticker on the motor for EPA rating
let me now if you need help

 Power may not be as well regulated for the Generac as the honda

71db at 21ft , Hondas rating is apx 7 ft or something and listing a
lawnmower as 95 db, so I dought 71db as my 7500exl is louder than 10
lawnmowers. noise wont be an issue unless it bother you, and it may, but
Ive thought about a new muffler.

 How many hours do you get on a honda, do you change oil as recommended.
Do you use an hour meter, generac has none, put one on. What breaks on
the hondas. One good thing is the Generac has an oil filter, I dont
think honda does, but still Mobil 1, 5-30 is best for long life.
Running on Ng or propane you lower end will be much cleaner and last
longer, but hours are critical in oil changes, not condition or color.
