Ok, I see I asked here: http://www.bobistheoilguy.com/forums/ubb...026#Post2380026

But that was a while ago, and it was about invertor-generator vs generator. Back to looking again. I noticed a 3kW jobbie at Home Depot that I think is too small, and lacks wheels on it--but when I mentioned it to She Who Must Be Obeyed she was very open to the idea of getting one this year. Although she did warn about going too small--or too large. We haven't had a more than an hour of power outage since the last ice storm (2009?) so really, running just the well pump, or just the furnace, or just the fridge is ok. A big generator would be nice, but as it is I have no place to store a generator right now. But what is a good brand?

I do have a HF freight down in Nashua, and Home Depot has a few generators in stock. I see Powermate, which is the one that is tempting me at the moment (3.25kW/4.05kW surge, vs 3kW/3.75kW surge, both with 240 recepticals) but have no knowledge of how good Powermate is. I saw a Homelite, which I thought used to be bottom of the line; it has a Subaru engine, which is good—but does that mean the generator head is low quality? Again, this is going to sit a lot, but I’d rather pay an extra $100 and know it’ll work until the engine is blowing blue smoke—that is to say, I’ll get lots of advance warning that the unit is wearing out.

I hear about this Champion 3500W, but I don’t think it’s sold anywhere near NH. I hear about Chonda motors being good but I’m not sure if that is what HF uses or not. Ideally I’d keep this investment below $400. At $500 I’m just going to put off for another time; or simply buy a smaller unit, as I just don’t need to run “everything” at once.

House specifics: oil heat, hot water off the burner, water pump, gas stove. Water pump is the only thing on 240. Transfer switch already installed, along with exterior hookup for generator.

Best I can tell the water pump is 3/4hp at 230V; max current of 8A. But that’s assuming the recommended breakers were installed, as per the manual (a reasonable assumption, but it would have been nice if the PO had simply written down what pump he installed on the manual that covers 10 different pumps). Old fridge, 25 years old. Oil burner furnace with horizontal flue (1/7hp burner but is class T motor, don’t know what the squirrel cage motor is at the moment). Those are the three big loads; I’m not sure if the microwave is on the transfer switch or not.

I personally would not go below 5000W normal for someone with a well pump. You need a clamp-on ammeter with peak hold to check out the starting load of your pump. Some of it has to do with its HP and whether your wire to your pump is a 2 wire or a 3 wire. (Ground is not included in the 2 or 3 setup. It has to do with where the starting capacitors are. A 2 wire setup takes a higher starting current than a 3 wire for same HP.
 
+1 the well pump is your great unknown. You might be able to approximate it by videotaping your electric meter: shut off all other loads and run a faucet until your pump kicks on. There is some way to reverse engineer how many spins of "the black spot" on your big dial are how many watts. If you have a "normal" non inverter generator it'll handle a half second surge that's too quick to see on the meter.

OTOH if you have a 5 hp gas engine with the resultant inefficiencies it should run a 3/4 hp electric well pump.

This is the generator I was looking at:
http://www.homedepot.com/h_d1/N-5yc1v/R-...0_0&cj=true
3kW, no wheels--but in wintertime, I'm not sure wheels will help as much as being mounted on a sled. And it's on sale, not for $330 but $240.

Edit: HF has this, looks similar, not nearly as cheap as the HD on sale; but what is a "Predator" engine? http://www.harborfreight.com/engines-gen...ator-69729.html

I'll have to look to see if I can find a clamp on AC meter. I thought I had one, maybe it's buried in my basement.

Also: I'm looking for a manufacturer recommendation more than sizing info. As I said, I'm ok with undersizing my generator; I just don't want to have to replace after twenty hours because it wore out or was otherwise junk.

How long does it have to last? I dunno--I guess a couple hundred hours usage is probably "good enough", anything more is great. I honestly don't know how long it should last, but preferably longer than its warrenty.

Pramac/Powermate stuff is good. They make large generators too.

I would not recommend a Homelite generator. They are made by TTI and usually have a good engine attached to the cheapest gen head they can get.

I was told B&S makes most of the gen heads sold, regardless of the engine make.
 
I would get a used one that looked heavy duty rather than a cheap new one. The cheap ones are using chonda engines. I think any generator will last longer if you run it less than full load.

B&S owns Generac, so everything that is just a rebranded Generac uses a B&S gen head.

TTI is a competitor though, and they source their own gen heads for Homelite and Ridgid.
 
I don't know if they have Pawn shops where you live, but this a great place to pick. Up a used generator. Most generators don't wear out. They die of. Neglect. I would look for a rugged built used one, over a cheap new one. The older cast iron Briggs are much better than the new OHV ones. They are litterally indestrucable. Honda is overated in my opinion. Your buying the name. Briggs stratton makes Great simple rugged motors, parts are cheap and if you store it properly, you will likely never have a problem. Gas stabilizer is a must.
 
I dunno. If they die of neglect, how do I know that a pawnshop/CL find wasn't one of those neglected ones? Also, don't brushes/whatever is in the head wear out on a time basis? Buying used means having no idea how many hours (unless if it has an hour meter on it--I don't think many do?).

One benefit of the Champion and OHV/ Chonda is they run much quieter. Many have car sized mufflers.

If you hate a generator after a hurricane blows through, chances are good you can sell the thing on craigslist for near what you paid for it.

I'd keep your ear to the ground, Black Friday is coming up and there are sometimes random web sales throughout the year. Someone on here got a 3k watt unit for $200 from home depot last month on a one day web only sale.

My well pump is shallow and only 120V/ 15 amps but you know when it kicks on on my 2500 watt generator. That pump might run a minute per hour, not much of a duty cycle, and if your generator can handle it odds are the pump will shut off before the head or diodes or brushes or whatever can overheat. Another concern should be low voltage killing the windings in your pricey well pump motor. But if your generator is struggling you should know it.
 
Yeah, I'm starting to look at dB ratings too. My boss pointed out that putting it under my deck (which has no walls, and it's about a story up) is a great place: protected from the snow, and easy location for chaining down (to the deck support 4x4's), so I don't need wheels after all. But that means close to the house (10' or so), so it might be worthwhile to pay a few extra bucks for low(er) noise as a result.
 
Hmm, ok, doing some looking, and I do find similar recommendations for a 5500W generator for a 3/4hp well pump elsewhere. I'll have to give further thought to this, as the better half indicated running water was the goal; but I don't think either wants that kind of cost.
 
My 5kw Coleman is 25 yrs old. I got it going after last October's snow storm. It is loud, recoil start, is on a little skid. A bare bones rig that isnt worth the trouble to use. It has a 1 gallon gas tank. It will run the house less the drier and oven. I have a 3/4 hp shallow well pump. rigged for 230. After I got it running last fall , I load tested it with a length of baseboard heat and a drier heating element. I would do it differently if I buy another one. I would look for a 5 kw , electric start, Quiet, OHV, A tank big enough to allow a 12 hr run. Got to have circuit breakers , be good enough AC to run electronics, a transfer switch in front of the main breaker.

Face it, most gensets are going to use just about the same engine set up and maybe different generators, all made similary for a given price. Prices are nominal 100 bucks per Kw. Most will work, but the key here is to over power for what you need. Gensets die quickly if they are forced to run the max all the time so get more than you need. Also, storage is also very important. You can easily take off the fuel hose from the drain cock and let that fuel pour back into your storage cans and then use that fuel in your car or yard tools. Bad gas is a devil. Around here, weather services give you a good solid 3 days of warnings before major ice storm hits. During that time, I'm filling everything I got up with gas. Ice is the worse because it can shut down a whole town and having no power, you can't get gas to run the genset. If they do got power, your in line forever. But with tornadoes, it's usually isolated and you can find gas 10 miles outside of town with out any problem. Plan ahead. You'd be surprised how many folks aren't, at least around here for gasoline, but if you go to walmart, shelves are almost bare two days out.....I just don't get that.
 
That's a good point; I go through maybe 5 gallons of gas per year in the lawnmower and snowblower. And I don't see myself dumping gas into the Camry--we track mpg's, plus I'd rather not dump "old" gas into it. It's slightly more expensive and all if there's any issues.

This is getting too expensive and complicated for this year.
