Great video. It highlighted the product details very well and the aerial shot of the delivery was cool. I am considering getting one and your video has helped a lot.
The last week I was installing a copules of this generator, this generator works with GasLP and it can bring to you a 20KW of energy and for that and that works with Gas makes that generator to the most efficient in the industry
I'm having a hard time trying justifying the difference between the air-cooled (Kohler 20 KW @$14.2K) and the liquid cooled (Kohler 30 KW Kohler w/500 gal LP underground tank upgrade @ $36K). The price difference doesn't add up so I'm still trying to figure that one out. We have a 17 year old 16 KW Generac w/250 gal LP buried tank that's EOL and needs replacing. Our Generac probably still would be running for years longer if the encasement didn't rot out from rust, allowing critters to make their new home inside our generator. After 6 years at this home so far the worst that we've had is a day without power, but you never know. We live in Florida in the Sarasota area and we're about to get hit with our fifth hurricane since living here. I don't see global warming getting better, and the pesky thing about hurricanes is they don't come in winter when it's in the nice '70s but instead in our fall when it's still in the '90s. Anyway, excellent video. You need to do an update.
@@ChrisMasto .. Here's a list of a few things off the top of my head: 1. Why did you choose a liquid cooled over an air cooled. Basically for the same price you could have gotten two air cooled 22 kW generators and had redundancy. 2. Any additional problems? 3. What would you have done differently? 4. What are you going to do if your NG goes out? I live in Florida and it's happened which is why we have a buried propane tank. 5. Since you have a Tesla, why not one of their powerwalls or a powerwall as an UPS? 6. Maintenance plans and monitoring? Basically all the above is what's going through my mind. I will call you mentioning about having UPS systems. In Florida we have brownouts frequently and basically everything that I care about has a UPS .. I have over a dozen of them which is why I'm seriously debating about a powerwall now that it can be used, as to my understanding, a whole house UPS. All my networking components including my ONT, switches, NAS, router, and obviously PCs plus all of my TVs and streaming boxes each have an UPS. My PC alone requires a $600 UPS. My point is by the time I factor in the overall expense and aggravation a whole house solution becomes more appealing. No doubt money if you throw enough of it can solve "almost" any problem.
@@ChrisMasto .. BTW clearly in your case, I understand why you needed the additional capacity because of your EV charging. If I wanted full capacity then 300AMP service * 120V or at least a 48 kW (guessing a 36 kW nominal load) generator.
I have a 30RCL liquid cool at my home in Florida. It just ran for 11 days non stop after Ian except for an oil change. The 1800 RPM generators run very quiet. Mine didn't burn a drop of oil. From what I've read online the 24,30, and 38 all share the same engine. A 2.2 liter. We had a discussion on the Generator forum Smoke Stack. The 2.2 liter engine Kohler uses in the 24, 30 and 38 is the Toyota Forklift 4Y motor. Its an excellent engine that will run for 30,000 hours with no problem.
@@Dqalex .. We still haven't made up our mind but more than likely I'm probably just going to go with the air cooled. The reason is we have another house in the area with a different power provider, and if all power is out for more than 4 to 5 days then we'll take a trip up north to visit family. Trust me though, I'm not a huge fan of noisy generators. We live in the Lakewood Ranch area and for whatever reason we're generally prioritized for getting our power up and running.
Liquid cooled is way better without a doubt when you're talking the about the vtwin air cooled models, there is no comparison... I have an older kohler 20rz with. the FAST RESPONSE 2 generator side, what a machine. In the future when its time to upgrade im gonna do something similar to what you have there. Nice unit!
Definitely more reliable- how would I know? Live in southern Louisiana, out of power 12 days due to Ida. Only residence in my development who had liquid cooled genny. Neighbors had to change oil every 48 hours, entire region out of 10w30 by four days, and I didn’t have to change till 480 hours. Day they installed my Cummins, replaced neighbors 7 y/o air cooler generac due to breakdown … with another air cooler genny. Regular maintenance that you can do yourself and expect 30,000 hours from a quality liquid cooler generator
Thank you for sharing your information and experience! We've still only had a few very short outages, but I feel pretty confident this thing is up to the task if/when we need it.
It's quieter than the 20KW air-cooled would have been, but it's still an engine. We haven't actually had a power outage yet, so it's hard to say how people would react to having it running for hours or days, but so far there has been no objection to the weekly automatic test. We can hear it inside our house but barely. Also, we're on good terms with the neighbors, and if we had to use the generator, we'd make sure to offer them a place to charge their phones or whatever. Last time there was a big outage, we could hear small generators all the way down the street, so I don't think we'd be a major contributor.
It's a great generator, but very cramped. The gas pipe with the two shut off valves blocks access. The oil filter has an extension so it stands vertical, which is less than ideal, though I assume those filters have a valve to keep it full of oil when not running. Stock up on filters and oil. You Need the Block Heater. My Generator Ran Terrible when the block heater broke. You have a Great Generator, I have the 35KW version (Aside from the Computer they are all the same and made by Delco) which has much more space. Good luck doing an oil change.
"I'll see you in the next video..." My butt is *so* sore from sitting here waiting. "But seriously," I just got an estimate for a 24RCLA and I'm planning to order it.
Sorry about that. Once it was installed, it has basically been a box in the corner of the yard that runs a self test every week. I'd follow up with a full "review" if we had an extended power outage to put it through its paces. Otherwise, not too much else to say about it. I hope yours is equally as boring. :-)
It passes its self test every week, that's all I can really say. We have had no power outages to give it a run for its money. I haven't heard too many negative reviews, maybe you just got a bit unlucky.
My one year old 24RCL suddenly shut down after running for 1.5 hours during a 16 hour power outage. The battery was fully charged and it has been doing its weekly exercise. The control panel is dead. Nothing is on. There is power at the transfer switch. After the grid power was restored, the transfer switch did not work. Had to manually move the switch to power the house off the grid. I spoke to the Kohler dealer who will come in three weeks to diagnose it, yes, 3 weeks! We believe the controlled has died. Have you ever had this issue?
That's unfortunate. I hate when a thing that you need for emergencies breaks during an emergency. Since I bought the generator, we have had no power outages.
One thing I've been doing, is that once every month or two I run a "loaded full-speed exercise", which does the whole switchover, in addition to the weekly unloaded cycle. That gives me a little bit more confidence that all the components of the system are functional. But if it's just your unlucky day for a capacitor to explode on the circuit board, there's not much you can do unless you want to keep a spare controller on hand.
Wow, your neighborhood just look like an European village: brick houses with natural gas. Didn't even know😁 You said you had a long power outage a while ago I'm just wondering: did your stove work...? In the Netherlands, gas is pumped around; there are booster stations in cities. So, they work on... electricity. Normality it has no sense to power them during an outage, because all gas heaters at home don't work: they all need electricity for the (small) circulation pump and electronics. Maybe they will put a generator for the stoves. But, I must admit you have some balls to install a gas powered generator. No guarantee it will work. At least not directly after a power outage. Or am I missing something?
The situation where you live is very different, apparently. There's nothing ballsy about a natural gas powered generator in the US, they are extremely common. And to answer your question: yes, the gas continued to work during every power outage I've experienced. It's how we heat our house. When we lost power for a week, I had to hook up a temporary generator to power the boiler's electronics and the pumps to move the hot water around, but the gas supply was uninterrupted. I've never experienced a gas outage. Here's a forum thread discussing this topic: www.bogleheads.org/forum/viewtopic.php?p=6495184&sid=2a7df5a01a4200ba1fafc2d51aa1e918#p6495184 And here's more discussion: www.jefftk.com/p/why-not-a-natural-gas-generator And here's a government report: www.nrel.gov/docs/fy19osti/72509.pdf "We find that natural gas provides the largest additional reliability compared to diesel for regions that face high risks of long outages."
@@ChrisMasto very interesting. Well in your case I also would go for neutral gas. How often do you have an outage? I think we, in the Netherlands, don't have much problems because we barely don't have power poles. All lines are under the soil. I think we have 2 hours of outage every 5 years. And mostly local issues at the local 10kV substations. That said...: haha, we did have an issue with a powerline which snapped in the air. Not by a blizzard: it where 6 high voltage transport lines, I think 150kV. They snapped because our airforce didn't have a map of the gridlines. Jeez, an Apache helicopter was flying over the river and crashed into the powerlines. 50.000 houses had no power for a couple of days. In the middle of winter. We had some flashing of our lights, and no outage happily.
@@gubbernl All of our power lines in this area (and much of the country) are overhead, and they run right down the street along (or often tangled into) the trees. (A random neighborhood with similar power lines: goo.gl/maps/2jECaBUVqfVj4gPG8) We don't invest much in infrastructure in the US, so this stuff gets neglected until there's a major incident. Add to that being on an island that gets hit with hurricanes, and all the climate change lately, and it seems like we can count on at least one multi-hour power outage every year, and huge ones every couple of years. It was the one in 2020 that finally cemented my decision to buy a generator. newyork.cbslocal.com/2020/08/11/long-island-extreme-heat-power-outages/ patch.com/new-york/portwashington/more-300k-without-power-long-island That being said, this generator is still an extravagance. I got it because I wanted it, not because I needed it. I could have used something much smaller and simpler if the only goal was to ensure we have hot water, a way to charge our phones, and a working refrigerator for those rare outages that last longer than a day. It will never "pay for itself" in any way whatsoever, but we will be more comfortable and happy.
It's a big box, but it's "only" 24KW. It's the smallest liquid-cooled Kohler. I covered some of why I chose this one already, but in short: * I wanted a liquid-cooled generator for the reasons I describe in the video * We have 200A electrical service, central A/C, an electric car charger, etc. This unit makes probably 70 or 80 amps on natural gas. One decision you have to make on sizing is whether you want to try to power the whole house or just the basics for emergencies. I chose to go big enough that if we ever have another week-long outage, we will basically not be affected by it. I would never say "need". We really don't need backup power at all, so this was mostly about finding our personal level of comfort vs. cost.
Great Video - Yes, the Liquid Cooled run slower and quieter and are More Reliable and provide better quality electricity. The maintenance is more, but worth it, you did Great. I have the 35KW Briggs Generator - I love these big ones: th-cam.com/video/ZfQxptYsk0w/w-d-xo.html
I have a 30RCL in my house in Florida. I should have bought a 38 or a 48. My house is 100% electric no natural gas for anything. My electric heat draws 15 KW alone. My hot water heater another 5 KW. Electric stove, pool filter, water well, RO water maker no way could I get by with a 20kw
@@Dqalex see, that makes sense to me, electric heat/ hot water uses a lot. but most houses on long island have natural gas or fuel oil for heat and hot water. no pool, low sq ft.
