I live in Virginia and was without power for 4 days after the storm that came through the mid-Atlantic Friday night. I currently have a 8kw "whole house" Generac generator with a 100A automatic transfer switch. Running 4 days straight just about killed it. It is leaking oil bad now, eating about one quart every 4 hours. The unit is from 1996 and has 350 hours on it. It is plumbed into a 500 gallon in ground LP tank.

I have salt water fish tanks, so I have to keep the generator running 24/7 or fish/corals would start dying within hours. That 8kw unit also runs the well pump, fridges and freezers, furnace and a lot of computer/tv/entertainment stuff. I have a 14 month old daughter and my wife is 34 weeks pregnant with a 2nd girl. To say she was upset with the heat due to no A/C and temps close to 100 and high humidity would be the understatement of the year.

My folks house down the street also was without power for 4 days, and they have a Generac Guardian 15KW generator that I installed for them back in 2008 or so. It also burned oil (didn't leak like mine) but due to bad rings or valves I'm guessing. It would shut down after 8 hours due to low oil. I would then top it back up, and have a really hard time getting it to start again. In fact, I could no longer get it to start the morning of day 3. My mother is 78, and the heat was really hard on her. Her generator was setup to run their 4ton A/C unit, but after day 1, it would no longer come on.

So I'm pretty much done with these air cooled non-continuous run generators and am looking at alternatives. I know that Generac offer liquid cooled units, but I think I want to steer clear of that brand going forward.

So I came across this John Deere 30kw generator:

Description as follows:

Continuous-duty diesel engine that operates at 1800 RPM and comes with a muffler and 4 point vibration mounts for quieter operation. This unit features a 2.4L John Deere 4024TF turbo charged diesel engine, electronic governor (0.5% frequency control), electronic engine controls (including snapshot diagnostic data), cast iron crankcase with reborable liners, full flow lube oil filteration, brushless generator end (fan-cooled), solid state automatic voltage regulator w/ stability adjustment and underspeed protection, turbocharged aspiration, electronic fuel controller, extended 500-hour oil change and filter interval, single-side service points, liquid cooling, residential-grade muffler, replaceable foam air filter element, heavy steel skid base and control panel w/ hour meter.

The combo you see above runs $8,799 from generatorsales.com, which seems like a good deal for a liquid cooled 30kw diesel generator. I'm curious if anyone had any experience with the JD 4024TF engine? Its interim tier4 btw.

Since its diesel, I was planning on getting the optional trailer with a 250 gallon fuel tank. The generator consumes 1.3 gal/hr at 50% load. I anticipate using well under 50% at most times, so I'm thinking maybe 0.75 gal/hr, which would give me a run time of about 14 days, which should be plenty I would think.

Here's the trailer with the 250 gallon tank:

The dual axle trailer w/ the 250 gallon tank adds $6,375 to the cost, but I feel this a much more flexible option than going with just the 250 gallon sub-base and sound attenuated enclose for $3,495.

I would then also add the two wire auto start option for $375:

And the 200A transfer switch for $1,295:

So the grand total for everything comes to $16,844, which seems very competitive to other 30kw liquid cooled options, let alone something that is tow-able with a 250 gallon tank.

I have 400A service to my house. Basically I have a 400A meter base on the outside that goes to a pair of 200A C&H panels on the inside. I was thinking I would consolidate all my critical circuits into one of the 200A panels and put the transfer switch between it and the meter base. I would love to be able to run both 200A panels off the generator, but that would mean a 400A transfer switch I think, which would be a lot more money.

Here's what I got to work with on the inside:

power1.jpg


The metal box in the middle the where the cables are feed from the 400A meter base outside on the opposite side of the wall. Off to the right is my current 100A transfer switch and 100A sub-panel. Those would both go away and be replaced with the 200A transfer switch.

And the meter base on the outside:

So I figured I'd just pull out the 3 cables feeding the one 200A panel and run new cables to the transfer switch, and then trim the cables I cut out for the run between the transfer switch back to the 200A panel.

Do you really need it to be portable? That is a lot of $$ for the trailer option. I wouldn't shell out $3K for their enclosure either -- I'd either put the generator in a barn/shed, or build an enclosure to fit. You could do something for a couple hundred bucks (even add automatic louvers if you want for a couple hundred more).

I was looking at the Kubota generators from the same company. Haven't checked out the specs of the Deeres yet, but will.

If you have a diesel tractor, consider using some sort of common tank that you can fuel the tractor from, and periodically have it topped off. That way, you know the fuel will always be fresh and you don't have to worry about long term storage (not a huge problem with diesel, but something to consider).

I started a similar thread a few months ago, and got some great advice here. Hopefully folks will be along to add their opinions. By the way, sorry to hear about your troubles -- these storms have affected a lot of people in VA. My family got lucky this time.

Peter, 1st thing is get rid of the coral tank. I had a 180 gal set-up for 7 years, lots of work and money. I have a 17 kw Briggs lp system. Does your gens run a cycle once a week?

Granted, a lot of money, but that Deere is one heck of a generator! Deere, as you may know, also manufactures a lot of marine diesels for all sizes of boats (I think the largest I've seen is about 120' (40 meters).
Anyway, that generator should be one extremely reliable unit and when comparing the kW output to the others on www.generatorsales.com, you're getting a lot of power. Most of the 10-12 kW units were in the $4K-$5K range, so the Deere unit is about 3 times the power for about twice the price.

30 KW is a big unit. Nice, but running costs and purchase price are both high. I agree that an 1800 RPM diesel is the way to go. I have a 10 KW Kubota powered unit, which I can power my entire house. The only things I can't do is run the hot water heater, dryer or oven without reducing other loads. But none of these are critical loads. When I "recharge" the hot water, I shut down the AC/Heat pump for an hour or so. Otherwise I can run all 3 zones of heat/AC, refriges and freezer and all of the creature comforts (TV, PCs, lights, etc).

I would get what you need, but don't go overboard. Running costs will be lower.

Each summer I typically throw a pig roast part in my field with live music, etc. I have been renting a generator for each such event. By having my own portable and quiet generator, I could forgo that expense. I also like the convenience of being able to have plenty of portable power anywhere I go. It is a lot of dollars, and I might rethink that.

Good point. My shop/barn is 250 ft from the house. I'd have to figure out what the cost of running power lines that far would be compared to building a shed attachment to the house in the vicinity of where the current generator is located.

If you have a diesel tractor, consider using some sort of common tank that you can fuel the tractor from, and periodically have it topped off. That way, you know the fuel will always be fresh and you don't have to worry about long term storage (not a huge problem with diesel, but something to consider).
Yes, I have 2 diesel tractors and would be looking at cycling through the fuel. I would need to be careful about not procrastinating in keeping the main tank topped off in case of a major incident what I would not be able to pick up additional fuel if needed.

Lol, I hear you on getting rid of the tank. I got a 150 and a 180 that share a common sump in the basement. The 180 for 3 x 250w halides on it and the circulation pump is a 330w hammerhead. Skimmers, heaters, chiller, etc. consumes a lot of power. Also got a 210 that is not in use at the moment. I might take them down now with a 2nd baby on the way. Way too many things/projects going on as it is! Yes, my current generator does automatically exercise once a week.

Paul, does your 10 kw Kubota sit in your basement? Are you venting the exhaust to the outside?

5 years from now nobody at the Deere dealership will know where Mother Deere sourced the head or other electrical parts for that genset. Full-line manufacturers outsource low-volume stuff like that and when the initial contract is up, most of the time the support vanishes. Buy a genset from a company that treats gensets as their bread and butter, not an afterthought.

Actually, the Deere generator is being sold through a company that specializes in generators (www.generatorsales.com)...not a tractor dealership.

How often are you to change oil on your gen?
 
/ John Deere 30KW liquid cooled generator #12  
just curious.. 350 hrs doesnt seem like a long time to me.. Is that typical for that size generator?

I'll admit that about 4 years ago, I disconnected the low oil pressure switch because it kept shutting the generator down. That took care of that problem, but I suspect it might have been at the detriment of the engine.

It exercises for 10 minutes each week, so that works out to about 9 hours per year. So that accounts for about 144 hours over the last 16 years. The rest has been spent holding a full load more or less. The hour meter has 5 digits plus a 1/10 one, so in theory, the hour meter will read up to 99,999.9 hours. That's 11.4 years of running 24/7!

I took a closer look at the unit tonight, and it appears that the oil leak is coming from the oil pressure switch. Hmm, maybe I just need to replace it and that will take care of the oil consumption issue and perhaps it won't shut down if I reconnect the wires to the new pressure switch.

The 15kw unit at my mother's house is definitely burning oil as there are no leaks anywhere. I spoke to her about it, and think I know the culprit. When I installed the unit in 2006, I told my father that he needed to change the break in oil after running it it for 4 hours at progressively increased load. Then switch to 5w30 synthetic. Well, I think the break in oil was left in it until 2008! Maybe it just needs new rings and valves?

Dang, that would be an awesome ser up, but a lot of money. Wondering if at that price a pto gen would be a better option, you already have 2 tractors. And at over 16k$ i would think you can get a top shape use 2wd tractor plus a well known brand pto genny. Than you ll have portable diesel water cool generator with an engine that can last over 5000 hour and an other tractor that have some use when power is not out. Just a tought.

Dang, Here I am researching what generator option I'm gonna choose (was leaning towards generac) and I read 3 failures just from your experience with them. Ughhh...........I'm getting on the ball with this, electrician is coming out next week for a consult and assist with sizing. I'm debating on a big portable unit @12Kw or a whole house standby. I could get by with smaller but I want central AC when needed.
 
/ John Deere 30KW liquid cooled generator #17  
The 1996 Generac is not comparable to the Deere. I look down my nose at the Generac, and smile looking at the Deere. I have a Kohler 20kw diesel in my motorcoach and a Yamaha 6600w gas for the house. SOunds like you need a backup genny. On boats where you need genny 24/7 there typically 2 identical gensets and you give them a rest alternating units. But marine gensets have unlimited cooling capacity due the availability of cool water for the jacketed manifold. So I like the yellow unit, just keep the fuel fresh, rent it out locally and get a backup genny for the main genny if you cannot afford to loose power. I am prepared for the 3-4 week icestorm outage that I hope never happens. PTO units are cheap and powerful. Not always wife friendly. There are commercial NG/propane units based on 4 cylinder car engines with liquid cooling.

This topic brings up bad memories of hurricane Ike and my 40kw Generac with a 4cyl. Mitsubishi engine.
Horrible piece of equipment suitable for standby power of maybe 6hrs in 90 degree heat.
I got them to give me full credit towards SG 70kw with a v10 Ford. Both running on natural gas with auto transfer switch.
If I could have, I would have dumped Generac and gone with Koehler for auto. Standby.
That said, if I ever move I will have a manual transfer switch with twist lock cables and a Multiquip trailer mounted diesel unit. These are rental grade units and are,IMHO , the best generator available.

Is the engine a briggs vanguard twin? If so the oil should be 5w30w. I use Mobil 1. You need new engines not new units. Hope all is well for you folks, good luck peter.

Howdy,
I had the same problem with the 400amp service situation. The transfer switch prices are crazy. I was able to work with my electric utility (Rappahannock Electric Coop). Its a special device which is connected right behind the meter. I made a posting about different transfer switches here.
generator-transfer-switch-connections
The unit says its rated at 40kw continuous and 48kw peak.

I use a tiger power 30kw pto generator with it. The tractors are always serviced and running. I do not have another engine to maintain. The pto generator is 30kw continuous with 90kw surge. It covers everything. I am very happy with my choice
