Some of these handheld oscilloscopes go up to 750+ volts, but only 10 amps. Not sure that works on 240 volts, 50 amp generator. 😳

Quote HistoryOriginally Posted By BJDFL53: So, this meter would produce a wave output without melting down? It's just looking at the wave form. The capability of that meter is measuring 10A.

I was telling my employer the other day that I was researching inverters. Today he came up to me and said, "Are you still sold on an inverter? I've got an extremely low-hour generator that has been in my way in the garage for probably 20 years. I'll give it to you for free as long as you don't take it just to resell it."
I jumped right on it and hauled it home tonight after work. The thing looks very nice. I haven't tried to start it, but I'm 99% sure it's probably going to need some carburetor work after sitting that long. The gas tank is empty, so that has to be a plus. I can certainly afford to take a free generator in to a small engine shop for maintenence. Is this thing going to sound like a dump truck driving through a nitroglycerin plant?     |

Way back when I used to race motorcycles, there were always some guys in camp that that brought some old jobsite generator with a fucked up muffler. They were really good at pissing people off. Smart guys would mount an OEM bike muffler to the existing muffler. It would make them a lot better to be around.

That's a VERY nice generator - Actually built for Sears by Generac (before they were bought out and split up by Briggs & Stratton). Has a Generac-built engine (made in Japan, IIRC) with pressurized lubrication - Has a real oil pump, and an automotive-style spin-on filter. Unlike most other portable generators with splash-type lubrication, the low oil sensor is actually a low oil pressure switch, rather than a oil level float switch. The power quality should be very good, as non-inverter models go - They used an exceptionally sophisticated version of AVR (automatic voltage regulation) in it. It will indeed be loud, but not as loud as some "contractor-grade" generators - Generac used a pretty decent muffler. There are dozens of brands oil filters that have a direct replacement for the Generac-branded part: Generac Part No.: 70185 Luberfiner Part Number: PH2840 STP S4967 BOSCH 3311 MOBIL_1 M1-103 FRAM PH4967 K&N HP-1003 MOTORCRAFT FL836 BECK/ARNLEY 041-8102 Wal-Mart (SuperTech) ST4967 WIX 51394 AC/Delco PF1233 Luberfiner PH2840 NAPA 21394 Pennzoil PZ-39 Lee LF2840 |

Quite the free generator. Looks in great shape too. As soon as you get it running you will want to start stockpiling fuel cans, because you will need it with that beast. Wish mine was that big.

Oh yee of generator wisedom- I have a 2k watt Champion “suitcase” inverter generator, a 3100 Champion watt inverter and just snagged a 4500 watt Champion inverter generator.
The 2k there isn’t much I can do about but the 3100 and 4500 are able to take “High Altitude” jet kits. I’m in CO and when camping I am easily at 9k altitude. Does a high altitude jet make a difference and if so, how much? Do I need one? |

Yes, it's certainly a monster -- and weighs a ton! I had to use ramps to load and unload it. Model number is 580.327180. The only owner's manual I can find online is for the 181, but the pics look just like mine, at least at a quick glance.
Thanks, @Skibane, for the very detailed post! It was very informative. @SR712, I'll probably take your advice and try to perform the maintenance myself. Worst case scenario (carb gummed up, etc.), I'll take it to a small-engine shop about 20 miles from me for service. I have a lot to learn, as I have nothing that plugs into any of those sockets except the standard "wall outlet" style 120V ones.  I wonder if there's a way for me to use the other ones for something? The only 220V things in my entire house are the water heater and stove. It'd be great if I could backfeed the house with it, but that would take lots of research on my part, as I'm not an electrical sort of guy. I do know that you need to isolate it from the main line into your home to avoid killing a lineman, but that's it. As far as the noise this thing will generate, I live in the country and my neighbors are at least 200 yards away on either side. Plus, I have to sleep with a fan due to tinnitus, so this dinosaur may put me to sleep. LOL! I'll more than likely still get an inverter. |

For a longer term outage the inverters will go further on less fuel, best idea is to get both or multiple inverter units and a parallel kit. The only thing I can't run in my house is the A/C and pool equipment. I'm considering a small portable AC unit. |

Everybody picks their pick.
With generators, I like the "two is one, one is none" approach. Needing to work on a broke-down machine when grid is down, is not my idea of a good time. I've got two of the HF 2K's...and the HF parallel box (which, btw was the best set-up and an absolute steal at $49--don't think it's that cheap anymore). If one poops, I got the another one, by my side. And, I can get by for a couple of weeks on ten gallons of gas, if I'm careful. Old skewl 3600 RPM-all-the-time...better have a lotta fuel. I'm in a coastal area, with exposure to hurricanes and potentially significant storm surge. I can fit one of the HF 2Ks in back seat footwell, if I decide to evac. Could I wrestle a 200# genny up in the bed? Maybe... Could I evac a whole-house Generac?

The main factor that affects fuel consumption is electrical load. For the same generator size and electrical load, an inverter generator running at 2000 RPM consumes just about as much fuel as an open-frame generator running at a fixed 3600 RPM. |

Noise or quiet isn't intended to allow you to sleep, it's to reduce your potential to draw unwanted attention. Fuel conservation by inverter generators is an even more important factor. Running all the house essentials for 8 hours on a single gallon of gas really extends your available fuel supply. |

Inverters do not run at constant RPM, open frame standard generators must. Load certainly consumes more fuel as the engine works harder, but an inverter at 1/4 or 1/2 load is going to consume significantly less fuel than a standard generator at the same load. As load demand changes the inverter throttles up and down. |

Example 3: Champion 3250 watt open-frame generator: 9 hours of run-time at 50% load (1650 watts) from a 3.4 gallon tank. That's 0.23 gallons per hour, per KW. Example 4: Champion 3100 watt inverter generator: 7.5 hours of run-time at 25% load (775 watts) from a 1.6 gallon tank. That's 0.28 gallons per hour, per KW. In these particular examples, the open-frame models actually delivered slightly better fuel economy than their inverter counterparts. And that would all be true, if loads were constant, which they frequently aren’t. |

There's nothing magic about the particular load chosen when specifying the fuel consumption of any of these generators. The same trend holds true over a fairly wide range of anticipated loads - i.e., anywhere from approx. 20% to 80% of max rated load. |

Smaller displacement engine, idling down and up with demand, driving a more efficient multi-winding
alternator, is more fuel efficient than larger displacement engine running at a constant 3600 RPM ( because it's needed to provide 60 Hz, not to provide higher wattage demand). Ask someone who lives off-grid and has used both types, for several years, on a daily basis. |

Ask someone who lives off-grid and has used both types, for several years, on a daily basis. Since the manufacturer's specifications don't show any significant fuel economy improvement for inverter models over their non-inverter counterparts, it's possible that any mechanical efficiency improvements in having a variable-speed engine are offset by conversion losses in the inverter circuitry. Converting 3 Phase AC into a variable DC voltage - and then into a fixed AC voltage - is never 100% efficient. There may also be some compromises being made in the alternator head design of inverter models, in order to make them as compact and lightweight as possible. |

Inverter generator shine where the motors can idle down or you need extremely clean power for electronics
3,600 RPM generators shine when there's a constant load 25% or higher |

WOOT has the WEN 56225i 2250-Watt Invertor Generator for $419 right now
not familiar with WEN but specs look pretty decent for it. HD has it for $524 WEN 2250 Watt Inverter Generator |
