Portable Diesel Generator Recommendations?

[Sawyer Rob]

Made me wonder what harm wet stacking actually does? Fowl up the Turbo which none of my gennies have, or the muffler?

I have a lot of diesels around here, and I've NEVER seem even one of them wet stack, even when run lightly loaded for many hours on end. The only wet stacking I've ever seen was on OLD diesels, never once on anything newer...

I'll bet the wet stacking "myth" will carry on just like the "diesels don't start in the cold" myth!!

I have a 3000 Watt Telecom Inverter all wired in with a manual transfer switch behind my automatic switch. But the 48 volt battery bank died and I have been "MEANING" to make an Anderson connector off of my 48 volt E-Gator. In the back of my mind, is the thought that by many days end, the Gator is 1/2 discharged. Not a good place to start for back-up. ALSO, I think the Telecom inverter is not very efficient. Idling, it probably uses a good amount of power. I do like it though. It's BIG, Heavy and transformer based, right up my alley! It runs my fridge/freezers all night, and the water pump no problem. ONE major issue. It has never liked the power from a generator as the frequency has to be spot on or it won't accept it. SO I have never been able to charge my battery bank off a generator with this unit. I tried to go in there to defeat the frequncy monitoring but can't get a proper schematic.



I just wish that the lighting circuits in the house were not mixed in with everything else. Then put a small UPS at the panel. With modern LED lighting that wouldn't take much of a battery. It would also be nice, because on an outage, you wouldn't be in the dark.

might want to talk the MEP guys, almost every single unit they get in has the "myth" wet stack. they show pictures of them blowing out all the carbon a lot on steel soldiers.

I wish someone would take apart MEP generators and reveal how unique or different they are and what one might have to be a-scared (lol) of. I love the concept and no-expense-spared designs, but have little interest in having anything with hard to find (or non existent) parts and components.

Really, I wish I had a house with a totally seperate Emergency lighting system. Probably run on an inverter. Because, a the end of the day, no matter how many generators I may have, when I decide to shut them off, I am in the dark.

I have wall hung oil lamps and candle sconces for navigation lights. I also have two Aladdin lamps and four LED camp lanterns. We don't leave the Aladdins untended, because we have dogs in the house, but wall hung stuff is above animal height and pretty safe. We have a little wall hung oil candle in the hallway that lights the way to the bathroom in the middle of the night.

One of the Aladdin lamps has a glass shade that diffuses the light nicely. The LED lanterns are obnoxious to look at on high. I'm puzzling over how to put a shade on or around them. I suppose I could just set a lamp shade over them. Batteries are not a problem, because alkalines have such a long shelf life. I keep a large shoebox full of batteries, which will keep a house lit for weeks. Plus, I have a dozen of the Hardly Fraught $2 mini flashlights scattered all over, in vehicles, night stands, junk drawers, etc.

My objection to generators is the freaking noise. Most of the time at my house the only sound is water in the creek and wind in the trees. I'm thinking about cobbling together a battery inverter system charged by a lawnmower engine running an automotive alternator. With a couple deep cycle batteries it would run the house for hours with no engine noise. I just bought an LED 4k smart TV that only pulls 60 watts.

I've seen very good military surplus generators go for cheap!. talk about quality.. U.S. G.I. 3kW Diesel Generator MEP-831A

My main genny sits in the corner of my garage/shop. A bit noisy to work in there with it going.



Outside, it's just a gentle purrrr.

My almost finished Onan 7.5 Inverter Quiet Diesel is so quiet, you can have a quiet conversation at the gnerator!

Well, yes, it is one of those spare no expense designs, and the parts are mostly mil-surplus. So, yes, not trivial to get, but not impossible, either. The basic generator is Onan, but the wiring...well let's just say they are wired entirely with white wires, and the master switch is custom.

But, they are well built, quiet diesel generators.

Yes the Army wet-stacked a bunch of them, but then stripped them down and rebuilt many them, so you can get very low hour units, some post rebuild, some just plain never used.

Wet stacking isn't a myth, and it can do quite a bit of damage to the exhaust, and valves due to carbon deposits.

You have to want to do your own service, and be willing to spend time on Steel Soldiers and other websites hunting down advice and parts.

YMMV....

All the best,

All Onan Generators are wired with white wire and have printed numbers the entire length of the wire. Nice for troubleshooting. That's where the niceness ends though. Onan always seemed to wire things in very odd fashion if you ask me. Like wiring relays in series.

I've been running a MEP803A for a few years. Bought it with 2600 hours on the clock for just under $1200 after fees. I did have to make a 500 mile trip to pick it up.

The year after I bought it Purto Rico got hit and auction prices went through the ceiling. I saw a low hour unit sell for $5700 today.

I run mine on a resistive load bank at 40 amps for an hour every month. I am told the wet stacking problem only happens after many hours of low load use. Mine had no signs of it and hasn't been a problem even when run for 5 days straight. During an extended outage we will pick a day to bake cookies to load it for a while. My house is popular during outages.

And enforced by Government Regulators requiring annual load bank for licensing

I believe running the generator at a high load just makes the valves and pistons much hotter, so the carbon gets blown out..

 

[user.69169]

I love dese threads. Mine's bigger den yers is. I need more power cause I not smart enough ta capture de waste heat off de engine. Engine wastes off more fuel energy as heat den it makes into electric powr most times.
Good God, what so hard about lookin at de electric bill and seeing how many KWH you use. Power company knows dat number for sure and prints it on bill every month.

I have a small 6 HP 3000 Watt Yanmar pull start diesel. Best starting engine I have, hands down, always 1 pull. I run it during long power outages to keep the freezers and fridge, etc. going. If I need more than that I have a 7500 watt Honda powered setup. Sound level is about the same. Not what the OP is looking for, but works well for my 3000 sq ft house with wood stove as heat. Power never goes out in summer up here.

 

[ultrarunner]

Do you have 240 with the diesel Yannar?

And, how old are they??

The units or guys?

Age doesn't matter. It seems any MEP unit that is lightly run may experience wet stacking. From what I've read a long run gradually increasing load will burn it out and cure the problem.

Sure it matters, I stated that I have never seen a "newer" diesel wet stack, and I haven't...

I have quite a few newer diesels here, NONE of them have ever wet stacked on me, even when run for hours on end at low RPM's, with a light load.

Last diesel I owned that wet stacked, was an -------> old D-7 CAT.

I keep reading on this sight, guys telling newbs, about how you have to keep your tractor/diesel under load or it will wet stack, like when running a lightly loaded PTO generator. I don't believe it, and it's another thing, one newb reads and takes as gospel and repeats it.

IF, it's true, why doesn't it happen to any of mine??? I have 2, 3, 4 and 6 cylinder diesels, you would think at least one of them would have that problem under a light load, wouldn't you?

My Yanmar 3.7 is 120/240. At the risk of saying things over and over. All my gennies go into an auto transformer and I only produce 240 on all generators and inverter, so the gennies are never out of balance, especially important on something as small as a 3.7. So I can easily suck 3.7 off one 120 leg and if it were not for the transformer, you would hear the genny somewhat unhappy.

My Deere 6200 seems to wet stack, if that what the greasy black goo on the hood and loader is. It has 1800 hours and never gets worked hard except maybe blowing snow. Never done any ground engaging field work.

 

[goeduck]

Do you have 240 with the diesel Yannar?

Yes, it has 240 and 120 outlets. I use the 240 to power the house at night when the load low,. Basically the 2 fridges, 2 freezers and fireplace insert blower... and enough lights so I can make it to the bathroom or outside to pee.
