Where do I start. There is so much wrong with this video. I've seen comments with the RPM discrepancy. They do both run at 3600 RPM. The STARTING wattage of these units is not 20,000 and 22,000. That is their nominal running wattages. Kohlers advertise their STARTING wattage, which in this case is in excess of 40,000 KVa for the 20KW. Generacs do not advertise their STARTING wattages. There is a reason. This is important in selecting a generator if you want it to start large motor loads, such as large central air conditioning units. It does mention that the Kohler is heavier. This is true. Most of that weight difference is in the rotating mass of the generator. The higher the rotating mass, the more inertia it has, which will counteract any large load trying to screech that generator to a halt when it is applied. Generac is the top market share because they spend enormous amount of money on advertising. I wonder how much money they spend on their generators? Generac also mentions in their promotional material that they manufacture engines specifically for their generators. All I understand when I read that, is that nobody else wants their engines for their power equipment. Kohler Engines have a huge following from multiple manufacturers. Kohler engines (in their horizontal air-cooled generators) have hydraulic lifters, while Generacs have solid, that require periodic valve adjustments. I'll let you figure out how many generators I visit that won't run because the valves are out of adjustment. I will tell you, the valves are out of adjustment because electricians think they are servicing the unit by changing the oil. This is why it is important to have a very well versed generator tech work on your unit. There are some electricians that do ok, but most leave a lot to be desired. Generator quality in my opinion of the four top market share manufacturers is as follows from best to worst. Kohler Cummins (a very close second) Briggs and Stratton Generac Yes, all generators have their issues. No you will not change my mind.

Ive been a generator mechanic for 35 years now. I've had more problems with the generacs then any other brand. Notice they leave Cummins Onan out of this comparison. 9 times out of 10 i find water in the oil when i service the generac air cooled units. Why? Because they only run 12 mins on exercise each week. Not long enough to get hot enough to get rid of moister and with the short run time they actually pull moister out of humod air! Generac's answer? Not to change the run time (cant be done in the field) but to tell your customers to run it once a month, under load, fir an hour!

This video is just a paper comparison. What the internet needs is a real electrician who's worked with both and which one they would put in their house, an honest opinion without trying to milk affiliate marketing.

We have used the kzfaq.infoUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!

Thanks everyone for the real reviews it means a lot I’m trying to decide .. Koehler seems to b winning!

I have owned a product of each manufacturer and currently have a Generac 24kw system on my farm. Both are good, but if you have one you must maintain it. Just changing the oil is not enough. Yesterday, I had the technician that installed my system do the annual service, that was not only an oil change, but a full diagnostic to ensure peak performance. Well worth the cost.

I have a 30 KW Kohler. It runs at 1800 RPM's its quiet and reliable. It ran for 10 days straight after Ian. I only shut it down to check the oil and for an oil change. Living in Florida I like the liquid cool generators better than the air cool ones.

At 2:49, you mentioned that the Generac turns at 1800 RPM. This is not true for any Air Cooled Home standby! The Generac utilizes a 2-pole rotor and therefore it must turn at 3600 RPM to produce 60Hz, which is the North American standard. Only the Protector Series (liquid cooled) has a 4-pole rotor which spins at 1800 RPM.

Given the reason most consumers buy a Home Generator is for emergency use your criteria for deciding which one is best is flawed. Reliability, installation cost, maintenance cost, and service availability are all more important than cost per kilowatt hour given most of these generators will be operated for a few days or less. Of course, if you are using the generator in an off-grid application or experience frequent long-term power outages the kilowatt hour criteria may be a consideration but still does not trump reliability or the other costs involved in installing and maintaining the generator.

I have a 22kw Generac and my biggest complaint is how loud it is. In your video you mention you can hold a conversation around it. Mine is not at all quiet enough to conversate around. If I could do it again I would go with a smaller, quieter unit.

02:50 Incorrect on the Generac RPM. All of these air-cooled engines run at 3600 RPM, either Generac or Kohler. You don't get into the 1800 RPM engines until you get to the larger, liquid-cooled engine models.

Any input on engineering standards? Which one has superior cooling and reliability?

Seems to be a Generac commercial. Generaac has customer service issues on different forum platform.

That guy has absolutely no Idea what he is talking about. First of all he is stating the starting watts at both units normal running watts. Kohler 20RESC or 20RCA are 20,000 watts continuous and 41,000 watts starting which is 210% starting capacity. Generac 7043 or 22kw Air cooled is 22,000 watts continuous and 33,000 watts starting which is 150% starting capacity. Further as many years as I have been installing generators all Air cooled generators run at 3600 RPMs. This is because of using a 2 pole vs 4 pole rotor. They are less expensive and allow for a smaller engine to run higher rpm to produce HP needed to make wattage. Third of all they are talking about the pricing of a Generac without ATS versus a 20RCA(L) Kohler that comes with an $800 Service Rated 200amp ats. Generac Switch of similar design is around $700. Kohler is more expensive by a few hundred even if you don’t get the same running watts but wait till you try to turn on a 5 ton A/C or 2 or 3 on the same generator. Hands down Kohler will win that battle every time. I am a dealer for both brands. Yes Generac advertises and holds a bigger market share in Residential products. But thats only because people prefer what they see more often than doing the research. This guy needs to read some more into the spec sheets before comparing. If you want to know more feel free to visit our site at Star-Generation.com you can find out how to contact us there.

This comparison merely reads the sales brochures and spec sheets. Uses stock footage, he’s probably never seen one in person.

I've seen in past videos that the Generac has a design flaw. The air filter box has a drain port for moisture build up. In sub freezing temps. this drain hole clogs up with ice and pressure builds up and blows oil all over the interior of the cabinet and making the engine oil level low. Now, I don't know if this flaw was ever fixed, but ,to me that could cause problems.

Kohler #1. Topgun. The Toyota of home generators. 💯

Good comparison. I'd of liked to know how those two compare in terms of Warranty coverages as well.

The images in your video show the General is 20kw, same as the Koehler unit

I would never own another Generac house generator. Bought one almost twenty years ago and had nothing but trouble with it. Came with several broken teeth in the flywheel right out of the box. Hard time getting warranty service too. Never again. I gave it away to a guy that I have do work for me. I replaced it with a 10KW multifuel one I bought on line five years ago. Runs on gas, or LP. I have to start it myself, and that's even better for me. No problems at all. My neighbor bought a Generac and had the dealer install it probably ten years ago and their out here having to work on it several times a year. Mine even has a hand start as a hack up in case the battery is low.

Also only generac liquid cooled units run at 1800 rpm. All generac air cooled models run at 3600 rpm.

When you do your shopping remember the product is only as good as the people that serve it!

You forgot to mention that Generac currently holds 82% of the North American market share for residential standby generator sales and they're the only manufacturer that regularly advertises on TV and radio to support dealer sales. 👍

One thing you forgot to mention the generac 22kw is on propane the same generator on natural gas is 19.5 kw. I have noticed a little condensation on the dipstick, so will start running for an hour once a month.

$16000.00 for a Generac 24kw installed at NJ beach home. Price included: The Generator The transfer unit. Building a 3 ft high platform - by code. Municipal Code permits and inspections. Plumbling for gas lines and Code inspections. Electrical inspections. Elevation Certificate from Engineering Surveyor for Code.Building permit for raised platform and inspection. Transfer line to opetated seperate stand alone garage. 4 exterior gfi exterior outlets. 2 Gfi outlets installed in garage. ** In NJ I would not install a home standby generator WITHOUT all the Municipal building code permits and inspections. The 24 kw is a bit loud running at full load. When and if neighbors complain do as I do and show tell them that the Generator has been installed and APPROVED per the Municipal Code office and I have all the approved closed out permits to prove it. If not you will run the risk of the Municipal Code inspector shutting down your unit / fines / and costly reinstall.

Everyone is talking just about the two Generators. They are both good Generators. The problem I have found being a Trouble Shooter for a large east coast Utility are the transfer switches. After an outage has been picked up we get calls from customers about the generator still running. All transfer switches I have found were Generac. I explained to the customer that they have full power at the meter. Since i am not allowed to mess with customer owned equipment I tell them to pull the cover off and they will find the electric plunger that operates the transfer switch is burned up. I have yet to find a Kohler switch burned up.

Forgot to mention the Generac uses a Gforce engine? It's the same engine used in formula one race cars.

Wrong wrong wrong . 22kw on lpg on 19 kw on natural gas. Surge wattage is way above 22kw. 22kw rating is constant power. Time to go back to school.

And consider how quickly you can find parts and service people to replace them if necessary.

Unless you experience frequent and long power outages, the fuel consumption numbers seem pretty irrelevant to me.

Kohler will go up to 120 percent of that rating. WHy dont you do a segment where you load bank both of them at the same time and see which one holds up. It WILL be the Kohler.

Generac 22kW runs at 3600 RPM as well.

I bought a 14 kw Generac ten years ago and the stator, rotor and control panel ate themselves at 16 months. Generac had a one year warranty at the time and told me to GF myself.

Pink energy went out of business due to crappy Generac products. Please research before you buy. I had a 20K Generac installed after hurricane Sandy. It never worked once when I needed it. The ATS froze and caught fire, almost burning down the house. Then the control board went bad. Never again.

This comparison completely ignores another significant consideration with code-compliant standby installations. If ATS (rather than manual transfer) is used, a load-shedding component is essentially mandatory unless you want to install a MUCH larger and more costly genset [702.4]. The Kohler shedding system is, in my opinion, far superior to the functionally primitive Generac approach, particularly if operation is likely to occur when unattended. This can also be avoided in well-planned new construction where emergency and non-emergency panels are organized to segregate loads at the outset, but the more typical experience is adding standby power to an existing electrical system.

FORGET Kohler. I was living out in the desert in Mexico and had a Koehler 20Kw generator as my backup generator. Thing ran exactly 48 hours and died. NOBODY in Mexico or the USA could fix it. I now have a Cummins 13KW and it runs so good. Wouldn’t recommend anything else but a Cummins Generator. Nice on the noise too.

I bought a Generac 18kw over 12 years ago from Home Depot. I paid about $1800 out the door(on deep discount because a new model came in) and another $100 for parts. I am a DIYer. It took about 2 days to do the complete install. I had a hvac friend check my gas line install. I did the electrical because of my military training. The only problem I have had is bad battery. So I change the battery every 2 years along a with a synthetic oil change.

For the first year of ownership the Generac would produce more energy and cost $6335.59 for 50hrs at a LP Cost of $2.40, while the Kohler producing less energy would cost $6806.52. for the same LP cost, all the while producing less energy, and more noise. The savings from the first year at 50hrs would almost pay for another 50hrs. My pick is the Generac!

I'd buy a Kohler, without hesitation.

I work for a generac dealer and let me tell you, buy a Kohler. Generac has major manufacturing issues. 2 of the same unit can be made with the same exact model, same production date, same spec sheet - open it up; different parts with completely different part numbers making it very difficult to source parts.

In my area, Generac is the only way to go. Not because it's better, but rather it's the only game in town.

Without objective reliability data, your comparison is meaningless. In true emergencies, that’s all that matters.

There is a reason why the electrical contractors I know call them gene-wrecks. Go with the Kohler and save yourself a lot of hassles and expensive repairs.

I will stick with my 1966 ONAN generator diesel

Kohler is best. I have one.

Kohler unit price included panels. The generac did not. Units are also not similar sized. I would not use this review to make a decision.

This is brutally loud, and my neighbors would not be happy with me. Why can't you and the other generator manufacturers look at the Malie DCA-45MZ Generator, which is quiet by design rather than loud and putting a bunch of installation around it.

This video is just a gloss over and really does not get into the important information. Generac is NOT a great product. It's good but has less quality, design and requires more professional servicing. The engine valve lifters are not hydraulic and need to be adjusted after a break-in period and again at 400 or so hours. It's louder and uses more fuel than the Kohler. The Kohler has better harmonic distortion specs protecting your electronic equipment. Kohler is a bit more money for very good reasons. Do your own research and see the true important facts. Who gives a crap on how much they weigh. It's not important.

Just because they advertise on tv does not make them the best. I can only tell you what I've read and seen. You like Generac? Fine. I'll get a Kohler.

When I lose power I lose the internet...so this will not turn on or off my generator...it is only good for monitoring...

Generac notoriously lies on their spec sheets. They've been sued multiple times. Ask dealers who work with both to give you their feedback. The joke in the industry is Generac is a marketing company that sells generators and Kohler is a generator company that doesn't know what marketing is. The quality and reliability, and warranty of Kohler is heads and tails above Generac.

Kohler dealer in Ione, California, gave me a price of $12,000-$15,000 for a 14kw backup generator. What a ripoff!

I heard Cummings is best

So this is an ad for Kohler. FKohler for that.

Odd that a 3600 rpm generator consumes less fuel them a 1800 rpm generator. Wonder why no one uses pulley and belts over direct drive coupling?

Genecraps are cheap to buy but expensive to repair......you see these cheap unit's at home center's in the front door......good luck getting service from these home center's, buy a Kohler or a Cummins from your local distributor and you'll get better service....if you call the local Generac distributor for service and bought your unit from a home center you'll wait weeks for service and you can't blame them, they didn't sell it and didn't make any money on it

Generator techs say don’t buy generac they are junk or anything that is air cooled stay the hell away from

Home come you are comparing a 22kw to a Kohler 20kw and saying they are comprable but you show a photo of a Generac 20kw? Shop apples to apples . Kohler outperforms your 20 and 22kw Generac all day long. Generac wont handle handle a full load without dropping Hertz. Want something to last 8 years buy a Generac. Want something for 15 years or more get you a Kohler.

I couldn’t believe when this video stated Generac used 93 (cubic ft) per hr. I would go broke using this generator. So I made my own calculations and it’s 93.6 cubic ft per day. Or 3.9 gallon per hour full load or 2.5 gallons per hour half load. Poor video

video is so full of errors - thumbs DOWN

Kohler! End of Story!!

This video is a joke do not listen to most of what you hear here.

Sick and tired of computer generated voice videos.

This is a puff piece at best, maybe AI generated.

Do NOT buy a Generac generator mine only lasted 3 years and NOONE will work on one trust me

I have a Kohler engine on my Xmark. It’s sucks😂 So. STFUP

I've read that Generac has a moisture build-up and freezing problem. Also, I've read some consumer reviews and it seems that the after-sales service for Generac is terrible. In my opinion, the Kohler is better.

Generac junk

Without objective reliability data, your comparison is meaningless. In true emergencies, that’s all that matters.
