Comparison Home Stand By Generators

[check]

I think you did miss a lot lol. The link that I posted brings you to a website to compare generators and they have Cummings, Hondas, Yamahas, B&S, Generacs and whole bunch of others. Try this link Electric Generators Direct | Specializing in Power Generators see if you get a different one if not I will find the right one. Funny when I punch it in I get the right site.
This is the original site Outdoor Power Equipment @ Power Equipment Direct - Outdoor Power Equipment Superstore - Power Equipment Dealer, Outdoor Power Equipment Store, Outdoor Power Equipment for Sale, Outdoor Power Equipment Dealers

Thanks, K man, I had a look at the reviews. All I could see was Generac after Generac, with a few B & S thrown in, and 2 Kohlers. The Kohler reviews were from people who at least had them for a couple of years, but the Generac reviews were mostly from people who just got theirs. So, little or no long-term reliability data, which is what I was looking for. Also, the website really seems to promote Generac/B & S.

We had 14 days without power in 2013. I had a new neighbor move in, he didn't believe he needed a generator. After a 30 hour blackout, he changed his mind....

Yes, piece of mind was worth a lot to us up in Cottage Country (North of Toronto). We of course HAD to have a whole house standby generator at the cottage, because we have a hot tub that must have power at all times in the (very cold) winter. And the automatic transfer switch was also a no-brainer, because we live 150 miles from the cottage.

One idea for those who don't want to pull your meter when installing the automatic transfer switch: (The instructions on our Kohler called for power to go first to the transfer switch, then to the panel.) What we did was to take all the breakers out of our main (service entrance rated) panel, and then instal a single 100 amp breaker back into it and run a cable over to the transfer switch. Then, we bought another 100-amp panel kit of the same brand (costing less than $200), wired it downstream of the transfer switch, and put all our breakers back in to this second panel. (Of course you have to have enough room to put the second panel close by, so that all your wires will still stretch to it.) The beauty of this setup is that we can test the generator from indoors any time we want, by simply turning off the single 100-amp breaker in the first panel, whereupon the transfer switch will act as if the power coming in to the house has gone out. Works great!

having just put in a small (175 gal) hot tub I wondered about that, dealing with an outage in the winter. But I can easily drain mine out on the lawn off the elevated porch where it is. 4kw is how many amps? Only really is an issue when compressor driven appliances or heating devices start up. Which in a modern home can be a lot of total demand at once.

I thought most well insulated hot tubs were good for a couple days. Where I live, I just can't imagine a multi day outage in the dead of winter. Fall hurricane, you bet. But in January? In NC? With Global Warming to protect me? ha....But if I lived in Canada, where a lot of the high quality tub brands are made, then what, dump the water on your deck or lawn and have it turn into a skating rink? Or over your walkway...So I can see why you would want to keep the heat in there. Which means you need a gen. And maybe a portable backup too...belt and suspenders.

~16 amps @ 240VAC

Watts/volts=amps

4000/240=16.667
7500/240=31.25

thanks, I should remember that from my college course, what a fluff course, electronics 101. I had to learn these things, which came in handy later on in life when I owned a Radio Shack store. In that course we had to build an AM radio from scratch and have it receive three stations. I got two and some static. Passed....it was the late Sixties.

Can anyone speak to the quality of the AC output produced by various generators? Did the consumer reports article talk about that? I'm sure there's some spec, but tighter is always better. Not a pure sine wave I'm sure, but how "good" is it?
And what happens when the motor bogs on full demand and those nice tops get chopped off? Doesn't that create heat in the appliance, another negative side effect like a brownout on a refrigerator motor?

Can't drain the hot tub completely, since some of the pipes will still contain water, and thus freeze and split. And we use it the most in the winter - love sitting in it with our toques on, catching snowflakes on our tongues - even at 20 below! BTW, our hot tub breaker is 50 amps, times 240 volts = 12,000 watts. Our standby generator is 17,000, so we are covered. (it would never use more than about 40 amps, but still, we need the big generator and are certainly happy to have it.)

Also BTW, the actual tub on our (Dynasty) hot tub is insulated, but the pipes that surround it are not, other than the flimsy enclosure and a very thin membrane. (Dumb design!)

Now there is a VERY good question - indeed, the Kohler guys made a big deal about how "clean" the power was on our model RES17 when we got it back in October of 2010, but I have not seen a comparison of the various brands anywhere. Wonder why not?

Here is a review from someone who seems to be quite knowledgeable (from www.complaints.com):

I would beg to differ with you on the buy Generac they will support. I am certified service for them all and Kohler is by far the better generator. The difference is Generac dealers are signed up by Generac, Kohler dealers are signed up by a distributor and have to work through the distributor, and yes some distributors are more industrial and do not understand the residential line. If you go to Kohlers site and look up the service locator I'm sure you will find a qualified service dealer. I would still rather buy a Kohler than a Generac I have never replaced a Kohler engine but have replaced many Generac engines. Lightning strikes damage pc boards there is nothing you can do to stop a close by hit from damaging a board

Calculating so Called watts via colts X amps and ending up with volt amps is the reason why a "correctly sized" generator will not carry the load.
There is the fact that a 1000W load on 120V can draw 1500VA if there is a leading or laggin power factor. Bubba adds up 4000watts, purchases a 4000Watt generator and wonders why the generator won't carry the load. Loading the 4000 watt generator with a 4000watt load that draws 50amps instead of 33.3 Amps as expected.
