Default Diesel Genset ?ís

Working towards finally going to contract on our new house. We will prewire for a generator. We will go diesel for a whole house system. Any leads on a go to source for the equipment? Also maybe some current brands to consider? I want to be sure I can get local install and service here in PCola.

Speaking out of pure ignorance here, but will this be mounted in an outside shed of it's own? Do you have a lot of land? I'd think the noise would negate the benefit?

Mine is very "quiet" but you can feel it when you are in bed (like on a cruise ship) it is in it's own building Turbo Lombardini ...

Just curious.
Why diesel? Diesel fuel sitting grows alge, condensation builds up, etc. Unless you have a fuel polishing system with it.
Why not go with propane?

Ditto... I would do propane every time.

Diesels engines operate at 1800 RPM. The propane genset engines run at 3600 RPM, are air cooled and use an aluminum block and the maintenance costs are considerably higher and the lifespan is considerably shorter than diesel. The maintenance on the propane gensets are considerably higher due to wear in those engines means you have to change the oil every 100 hours. Diesel gensets require an oil change every 500 hours. To put this into perspective if you had an extended power outage, do you want to worry about an oil change every 4 running days or every 20 running days? Personally I wouldn't want to have to change oil on a generator is the middle of a week long plus outage. The life expectancy of a diesel genset is about 20,000 hours, the propane is about 10,000 hours. Look at what a generator costs to run for one day. A $5000.00 Propane Generator / 3000 hours life x 24 hours = $40.00 a day A $10,000.00 Diesel Generator / 20,000 hours life x 24 hours = $12.00 a day.

Fuel cost, here is where the DIFFERENCE really is if you want to toss everything else out the window. As of April 1st, the average residential price per gallon of propane was $4.70. A propane genset will use just about 4 gallons per hour X 24 hours totals $451.20. During an extended 7 day power outage you are looking at $451.20 per day X 7 days or $3,158.40 in FUEL alone. DIESEL, the current average price per gallon based on a Google search is $3.21. Dieesl gensets burn on average 1.3 gallons per hour X 24 hours based on the $3.21 = $100.08 per day X 7 days $700.56. You could run the diesel genset for a full month for what it will cost you to run the propane genset for one week.

Diesel degradation is a concern yes. Did some reading and Exxon stated that diesel that is PROPERLY stored will last 6 months to a year without any significant degradation. If it's properly stored and in our case in an above ground tank and we add in Diesel Sta-Bil it will help to control the degradation. So that is why we are going diesel.

If you have natural gas, its a better choice and unlimited supply. Next choice propane with a BIG tank. Then diesel then gasoline. However some good points are made by Badbagger.
If you are set on diesel, see your local Cummins/Onan dealer or Caterpillar dealer.
In any case buy from the same people who will install it.

Solar would be much better, quiet, no need to refuel

If I was setting up a whole home system and owned either a diesel truck or equipment, it would be a Wacker 20kw diesel towable, with the optional extended run tank. It is one of the few ďstudio quietĒ diesel generators that has auto start capability. Big tank serves double duty to refuel farm equipment or whatever diesel equipment you have. Just add a 120vac transfer pump, and use the generator to power it whenever it is needed. Refill anytime you get below 1/2 tank.

If you have access to, and a way to keep Diesel fresh, it is superior in nearly every way. Not to mention is a fraction of the noise.

Initial cost being the big negative.

Get a 275 gal storage tank. Own a diesel truck or car. Draw off that tank to run your car. Then just refill the tank. That keeps fresh fuel and saves auto operating expenses

Buy diesel at the beginning of the hurricane season and treat it. If you don't use it in you generator just put it in your diesel truck a little at the time after the season is over saving some for regular engine exercise. This way the fuel is fresh, has no algae or much condensation. I've done this since Katrina with no problems in either my Lister style engine that drives my generator or my 7.3 Powerstroke, a little inconvenient but when the power goes out I still have dependable diesel powered electricity.

Get a Kubota engine with a Stamford or Newage or other industrial electrical end. Many packagers out there, I don't think any are much better or worse than the others. Look in Boats and Harbors, there are many ads for radiator cooled diesel gennies set up for industrial or work barge use. Cost is not that bad. Those will be noisy, but depends on where you install it. If you want a soundrproof unit, it will cost more.

I have a 8kW Kubota with an Onan electrical end and no sound box. It's installed in my detached garage that is about 40' from the house. Radiator cooled with no sound box with exhaust going out the back of the garage. From the house you can not hear it. It is 25yrs old and has like 1600hrs on it. I'm at the "end of the line" in lineman speak, meaning I'm about the last to get power after a storm. Once I toted it up to a buds house near Chapel Hill that had a new baby and no power from an ice storm. It ran ten days solid before they got power back. Longest it has run here was about two weeks. Glad I went diesel!! Propane would have sucked.

Diesel stores well even for years. Do use a stabilizer and have a way to "sump" your tank to get settled crud and water. In my case my car and boat are diesel, so I buy bulk fuel and fuel everything from the tank. So longest fuel is in the tank might be six months. Can store much longer, just look at things like hospital emergency gennies. They are careful with the fuel but it might be many years old.

I'd love to see the cost and area needed to have a solar system run even a few window units 24/7 plus fridge, TV etc.

Much of Fl. does not have NG, I'd say 80% of the homes I see on realtor.com have electric stoves.

Not a lot of natural gas in Florida. Iíve lived here since 1967 and have never lived in a house with gas.

Sure would be be nice for a generator though.

Look up powertech generators we use them for over 20 years in the buses we build we also use south eastern power for generators.

Your fuel cost are a little skewed.
20kw natural gas only burns 3.6 at full load 2.1 at 1/2 load.
10kw NG looking at under 2gal/hr at full load. Probably closer to 1gal/hr at 1/2 load
20kw diesel burns 1.8 at full and probably 1/2 that at idle
10kw diesel much less.

Also so for a home use unless you live in the worst place possible you will never come close to reaching the average hour lifespan before either unit rust out completely.
