Servicing and transfer testing a 24kw Generac standby generator 

One of the few that actually shows the air filter change, thank you.

Retired builder here ... really cute helpers you got there ... definitely good training for them to start learning basic, tools, maintenance, etc ... i run a portable generator with a whole house hookup,... I've contracted and hooked a few up (via certified generac installers) ... funny how you mentioned running unit with the fuses out first ... had a really wealthy rich Wall Street guy ... built him a house and he wanted 2 units (redundant) because he lost power a lot in the country ... showed up one morning after a storm and he was livid, lost power and neither unit stayed on ... both ran and didn't power the huge house ... tech came out, checked boards, okay, checked fuses, both blown ... he had good luck with them afterwards ... but boy was he pissed that day ... probably 50K invested on both ... i watched the install video's .... as a shade tree car mechanic, I would have removed the battery terminals and cleaned (wire brushed) ... bad connections and bad grounds kill batteries prematurely ... other than that I like that you checked and cleaned everything ... that's the way I was taught

Just got me a 24kw Generac a few days ago. Can’t wait to get it installed this week. This last Hurricane had a lot of us without power in TX for days. I ran my old 9000 w Generator and it kept us good but running out looking for gasoline was not my favorite thing to do. I just couldn’t give up on my grandkids like that. I feel much better knowing the next time they’ll be nice and comfortable here with Grandpa.

watching your aon be right there with reminds me of me and my daddy 45 years ago. There wasnt one thing that i didnt help him do. its great that you and him are working together.

Little helper is so cute

Thanks for the great video! You have one cute little helper there! He's going to be a very knowledgeable young man, as you are teaching him so much just by having him by your side.

Thank you for your demo on servicing the Generac Guardian 24kw. I purchased one in Sept 23 and feel much more relieved having it just in case here in Texas.

I've had my 20kw Generac Guardian about 9 years. It is connected to a 1000 unit lp gas tank. I do my own maintance and it is easily done as done as you are showing. Mine has been trouble free and reliable and i would definitely recommend it. Thanks for your great video.

I just bought mines, definitely getting an electrician, but its good to see your videos so if I do have questions, I'll get similar answers based on your video!!

I so love my Generac 20kw! I've had it installed now going on it's forth year, and while the first year and a half it wasn't used to supply house-hold power, the past year and a half it's been used nine times - two of those times for six plus hours each. I'm still on the maintenance plan from the installer for another two years, but after that I'll most likely switch to self-maintenance as it doesn't seem to be that difficult. Thanks for sharing!

I watched all your impressive professional generator installation videos. Now I know how one is installed properly. All I need is a helper like yours when it needs servicing!😉 Couple of helpful suggestions I should mention, which many mechanics will agree. To prevent oil starvation in the first moments when the engine is first started after replacing the oil filter, fill the filter with as much oil as possible but not enough to spill out when reinstalling the filter. And, since baking soda is a base, if any should get into the battery cell the acid will weaken. When I install a battery or clean up the corrosion on a battery I put axle grease on the battery post and clamp to prevent oxidation. 🙂

That's a good idea to let fresh oil flow while the plug is still open. I'm going to start doing that to my vehicles once a year or so. I've always been concerned about that residual oil left behind.

Good morning farm families going to pour my pad today for my 24kw in a couple weeks hopefully install the generator. Watched your video on that too. Awesome keep it up Brother.

Hello from Foxfire, NC Thanks for the tips! i have the same one 22k now I can do my own service !

I've enjoyed watching the Generac videos, after Hurricane Sally hit us direct in 2020, we've been greatly considering one of these, we are in hurricane alley, so better safe than sorry, we also have random power outages and severe thunderstorms often enough to justify the need.

Our 24KW takes 5W30 oil. If youre under warranty then you MUST use generac's branded oil. I guess its formulated for the generator. Oil filter can be a comparable cross referenced brand. We love ours.

Thanks. My 24K will need annual maintenance in about a month. It looks easy.

Good idea EMP-proof

I need a generator for my house as well. Ive been looking into one but i was thinking of installing it myself i do have electrical experience but i sometime question myself to much at times.. we have natural gas so that would be the way to go for me.. thanks for sharing this.. as always god bless and stay safe from the buckeye state..

on batteries voltage is one measure but for an accurate test it should be voltage under load (a resistor) ... there is test equipment that does better for that than a voltmeter. Thanks for the walkthrough

Buen trabajo amigo, muy profecional y muy bien explicado todo. Gracias

thank you for shearing it is very helpful ... keep up the great work

I always label the oil filter with the date of replacement. I also put a computer hard drive magnet on the back of the oil filter. These neodymium magnets are very powerful.

Thanks for the tips! Have a great one! 👌👍

The manual calls for 5W-30 oil not 5W-20. You may want to measure out the 1.9 quarts before guessing the amount.

I have the 24KW and I use the app to monitor the voltage.

Good video thanks !

The battery cables/terminals had a ton of corrosion & only removed it from the outside of clamps & terminal but never removed the battery cable to properly clean the battery terminals & inside of battery csbles cable clamps with a wire brush or sandpaper to avoid a no start situation when you need the generator most. If put a small amount of wheel bearing grease orotund where the battery terminals protrude up thru the battery case prior to reinstalling the cleaned battery cables that will stop the acid from weeping thru that area causing the white/green corrosion too. Lastly the voltage was good on the battery as you stated but you may not be aware a std good cond flooded or new maint free lead acid 12v battery has an idle fully charged voltage (off the maint charger for a few hrs) of 12.6v-7v & a newer Gen more expensive AGM 12v battery has an idle fully charged voltage of 12.9V. Hss as port Wrenching Genracks.

Speaking of oil. The Generac oil probably has zinc in it. Most all modern synthetic oil is void of zinc. There are zinc additives that can be added to oil.

at 1:50, you should toggle that I/O switch to the O position so the generator doesn't start.

I have an opportunity to buy a Generac 24KW generator with the transfer switch, but wanted to know what it would cost to install. Most of the work you did I can do; the pad, instal of the transfer panel, wiring, etc. that said, Generac site says it can cost about $5k to have it installed. They go on to say that’s you need an electrician certified to work on Generac to do the final adjustments to make it run properly. Is there a lot of adjustment needed once installed? Appreciate you doing these videos.

Cool video tutorial my friend. I have a couple questions. Did you get a 22 or 24 kv generator? My house is approximately 3k square feet with 2 ac units single story house in Houston area. Also how often do you manually operate the generator per year for general maintenance? Thanks again and I’m glad I found your channel.👍 19:01

Great video. Can you explain how you would configure it to be completely manual and not use the ATF. If I wanted to manually turn it on and off manually how would you do that? Sort of like running it like you had an interlock.

my neighbour has a generac and i swear i hear that thing once a month they must do monthly maintnence

Are these whole home generators good to run the whole house as the name implies? From what I hear you have to do the standard house calc just as you would for the service. Thinking about getting more involved in this field for work.

Can you provide more info on why you had to add a ground bar to the transfer switch?

I'm thinking about the 24kw. It's probably more generator than I need but I read that a 22kw uses more fuel than a 24kw

Were you using Kirkland Oil in that?

Sounds like it could use a valve adjustment, startup was kinda rough

Can someone tell me ball park cost of Generac 24kw unit and their installation in the Atlanta area. And if I should go through Costco or calling them directly?

How to raise great kids!

I've been hooked up for 15mos and I have yet to experience an outage. We've had one or two but I wasn't home and My generator was off.

They ordered my generator 8/11 they tell me 2 weeks to get it then 3 more weeks for installation I got the 24kw. I could of got by with the 22kw but it would be cutting it closer

You cannot do battery maintenance without disconnecting the battery charging cable. It makes you volt test invalid and could also cause harm

will it turn on if there is a brownout

Why such light oil. Your temperature doesn't get that cold.

Why are so many of these batteries corroding

It is a 24kw not 22.....!
