Today we inspect a generator shed I built in 2017 for our Harbor Freight Predator 8750 watt generator. Prior to building the generator shed, we lost power many times. Once I completed the construction and install of the generator, we have lost power once, and we didn't need the genny that one time. The Predator 8750 is big enough to power our whole house. It may even run the A/C, but we have never tried it. It works awesome!
The shed is built with cedar siding and a roof that opens for easy access to the gas tank and generator removal. I even sized all of the wiring and generator shed for a larger 50 amp generator, if one day I choose to install one. The generator shelter is insulated and provides airflow so the doors can be shut while the generator is running, greatly reducing the noise of the generator. We designed and built the shed based on previous interweb research. I am extremely happy with the design and it works well.

We have used the th-cam.com/users/postUgkxOTeIs0vv4_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!
That shed looks better and is built better than my house.
The best generator shed I’ve seen.
Awesome!
Get some rock wool insulation. Line the inside and it’s fire proof and would soak up the sound and noise like crazy.
I agree. Some 1 or 2 inch thick rock wool would make it much quieter.
By far the best homebuilt generator shed I have seen.
I built a generator shed just like this one last summer 2022. We had a tornado March 2023 we had no power for 5 days. This design worked great for me, the hinged roof was so nice to add gas and change the oil. I kept the doors shut and the fan kept the shed cool. Thanks for sharing.
Living in Florida without sufficient power to run the A/C when the grid fails gets old very quickly- about 2 hours. One never knows when a severe thunderstorm will knock the power out for and hour or two, or longer. Then there's hurricane season. So I just got a 9500 watt generator to replace my little 3500 watt machine. We were once without power for 4 days. I have two refrigerators and a freezer loaded with meat. Now that I have the power I need, I was looking for a way to quiet my system down, and you just gave me some great ideas. Your gen shed looks great and has enough room for storage of fuel for several days. Thanks for taking the time to make the video and the great ideas. I especially like the way the roof opens so the generator can be refueled easily.
Sounds good! Thanks for watching!
No one never ever puts a generator that far from the house. It is always on the side of the house. The cable must be huge. The rest of your shed is great. Great explanation. 🙂
The cable is actually sized if I were ever to install a 50 AMP generator (I used 6-3 wire). It's actually not that far of a distance but I wanted it as far as possible to reduce the noise I'd get in the house. You can put it as far as you want as long as you properly size the wires for voltage loss. Southwire has a nice voltage drop /wire size calculator on their website and we are all good there :) www.southwire.com/calculator-vdrop
Thanks for watching!
@@OutdoorsEngineer The down side to quiet, when you sleeping with it running... someone can steal it and you won't know it until you wake up. Mine is about 15 feet from the house. I know when it stops in my sleep. 🙂
@@2fukWu ONLY???? The larger the size the higher the price and harder to work with. 🙂
went 13 days with no power in 08 when Ike hit Texas, got a genny now, the old type land line never quit and family were able to call us 24/7
The old time land line. Ha. Phone with a curly cord!
Love the shed design, especially the hinged roof. This gives me some ideas for my next project.
It works awesome. Thanks!
Fantastic design and the way it blends into the nature setting is awesome!! Great job!!!
Looks like a good job and it is quiet, nice.
Thank you!
I have just finished milling some cedar that I was going to use to make raised beds for the greenhouse. I've decided to build a generator shed like this one and mill some more cedar later. This is a great design.
That is awesome!
This is the nicest generator shed build that I’ve seen. 😍
Thank you!
Hope you enjoyed our generator shed! What do you think?
Beautiful Generator Condo! 😎 I'm also very impressed with the noise reduction, and the hinged roof! Nice work! I have a little different set-up, I have two 2500 watt Champion dual-fuel inverter generators (Gas/Propane) since we are miles from any Natural Gas pipeline and can run the house for 10-11 months (stove, oven, water heater, clothes dryer) with our 250-gallon propane tank. My thought was fuel efficiency and portability, I can run one or both generators in tandem depending on the demand and run them both for months without needing fuel. I can also move them easily to anywhere I need power since they only weigh 40lbs each but combined with a parallel kit have a peak output of 5000 Watts, more than enough to run everything in the house (excluding Central A/C). My shed is 8x8x4 and 2x4 framed with exterior siding and insulated with *Rockwool (sound-absorbing, fireproof, water repellant) insulation. I used 50amp breakers and 6Ga. wiring with a main breaker interlock, all connected through an additional breaker panel with 30 and 50 amp RV outlets, mounted alongside the outside garage wall. ~Roy~ *Critter Ranch, Apple Valley, CA.
Great need those build plans 😊
@@khiaraslaw I probably have some old cad drawings of them laying around!
Fancy schmancy. I especially like the underground wiring.
Do you have the plans? That is one nice shed
Nice looking gen shed, I am getting ready to upgrade our gen shed, we also have the same gen 8750, it has helped us over the years, one time our power was out for 7 days. I am also working on a small solar system, and that also came in handy. Loved the video!
best example Ive seen. I like the forced intake and exhaust system.
Wow, super quiet and very nice looking.
Yes, thanks
Great job and thank you for sharing and explaining it so well.
shed looks awesome. Great job.
Thank you
That is well built. Like how the roof hinges.
Beautiful looking shed. Great job !
Glad you like it!
I DO LIKE IT ! I had a generator at my last house. The problem with it was I built it too small. The size of yours is good. Good job. CHEERS.
Great info and a nice simple approach. Thanks!
This Generator Shed is very Well Done 👍 and Great job 👍
Thanks!
A solar trickle charger to keep the battery topped off would also be a great addition.
I usually start the generator once a month and let it run 15-30 minutes. Have not had a problem with the battery yet. Not much draw on the battery when not running I suppose.
fantastic setup
Nice design but I would put some angle slats on the exhaust vent to deflect the noise to the ground. Also put some exercise rubber mats on the floor and the doors to absorb the sound.
Heading out this morning to pick up an 8750 on sale! Great video with several great ideas.
Have fun!
Looks good! I’d bond the ground rod to the house service ground in case lightning ever strikes in the area.
Not a bad idea
Excellent video. I am preparing to build a generator shed very similar to yours. I picked up several tips from you that I can use to make my design better. Thank you.
Awesome!
Living down South we deal with the Hurricanes Every year,just got us a nice 8700 as well. This Generator House is great I'm gonna build one for ours as you know they are LOUD. Thanks for sharing
Sounds great!
beautiful design and detail!
Thanks!
Really like your shed design. I am in the process of building mine and will incorporate some of your design into mine, especially the roof and fresh air intake.
Awesome!!
I only needed my generator 2 hours in the first 8 years of ownership. The freak windstorm in August of the 8th year that knocked my suburban power out for 60 hours had me so happy I had it. Neighbors lost freezers full of meat & refrigerators full too. It paid for itself 3x over that one time. Since then 5 more years it’s been used for 2 4 hour outages. Not terrible but with wife working from home very necessary
Yep. It's nice to have just in case!
Nice work. A lot better than mine.THANKS!!!!
Best gen shed I've seen so far.
Thanks!
Good job! Thanks!
Nice shed, good job. BUT , I would have put it on my deck or at the bottom of the steps because in a severe thunderstorm you gotta trot way out there to start it . Plus way less wire (expensive) but more noise but in an emergency I can put up with noise to have power. Just my flea bitten opinion . I still am impressed by your setup I know how much work you put into that !
Excellent and beautiful work ! thanks for this video
Thank you! Cheers!
Nice job !! Nice house to.
Nicely done my man. Great ideas and just in time for my forthcoming generator rollout.
Awesome!
First time seeing this duct fan setup nice
Sweet generator house!
Thanks!
Great vid, so helpful and simple thanks
Glad you liked it!
Nice job!! Greetings from Brazil
Thank you very much!
You don’t buy a generator to keep your electricity on, you buy it to keep the electricity from going out. 😂
Exactly!
That is a bad ass gen house 👍🏽👍🏽
Did a nice job 👍
Thanks!
Nice job!
Thanks! I should have an update out in the very near future. I upgrade to an inverter generator!
great dog, nice design, pretty complete
Thank you very much!
Quietest gen house video I seen yet. The plastic garden shed ones don't seem to cut the noise that much
That was my main goal. Keep the noise level down, especially if we need to have some windows open in the evenings. Haven't really had to test it out with that respect because I still haven't had a need for using it since I installed it.
Nice and quiet
Nice job
Thanks!
nice shed
Set it on sand will make vibration better, not too bad for a Predator gen they are not known to be quite.
Certainly not quiet. The shed certainly helps.
Pretty good one of the best i seen
Reallly nice job
I'm glad you like it
Not sure about Wisconsin, but for here in Texas, I’d put some finer mesh screening over all your vents. Our wasps and hornets here will find a way to get into any structure and make giant nests.
We have wasps and hornets, but they usually build nests under overhangs., and I promptly knock them down if they get in a bad spot.
Very nice work
Thanks!
@@OutdoorsEngineer 🥰
Very nice.
I really like your enclosure A LOT. The only thing I might do differently would be to have the intake and exhaust on the respective sides of the enclosure to eliminate as much of the bends in the air flow pipes. Fewer bends make for faster air speed. This would also prevent any exhaust fumes from being pulled into the enclosure. You can also find pistons, similar to what holds the hood and hatch on a car or truck, but heavy duty enough to support the weight of the roof which would make it much more stable than the 2x4 you're using in this video. A sudden strong gust of wind could lift the roof off the 2x4 and allow it to fall while you're under it.
Good points! I did make a Tee on the exhaust that pushes the exhaust away from the intake. The main reason I went out the back was to minimize noise on sides that face the house.
Great ideas for my Duromax 12kw. I defiantly like the hinged roof idea. Only comment is the length of cable to house, voltage drop. I keep my 240v 50a service cable no farther than 25ft from house. Just an opinion, everyone has one...lol
For sure! It is something to consider. I did plug my numbers in I think Cerro wire's voltage drop calculator and all good. It's always a good thing to consider the voltage drop. Thanks for watching!
Great design. I converted our 8750 to liquid propane. There's a kit for it on Amazon.
I have thought about making the conversion - - If I used it more I would!
i was considering the generac or the enphase, but for the cost i could buy 1 generator a year for 30 years.. so im gonna build a generator house, for the emergency,, whenever SCE decides to turn it off i will still have power,,, thank you
Love the shed. I wish you had maybe included dimensions of exterior wall length and depthfront and back wall height and roof frame exterior length and width.
If you send me an email at inthenorthwoods.yt@gmail.com I can send you the basic plans.
Really like the Gen house. Nice design. Pop-up roof is sweet. Good job. Might want to get a single lug or crimp-on eyelet on that ground wire to clean it up a bit and enhance the connect. How did you hinge the back of the roof? Thank you.
Thanks! They are just old interior door hinges. They stay out of the elements and I made sure they got full of stain so they don't rust. I think I have 3 hinges on the back of the roof.
Oh, and good idea on the ground wire. I'll have to look for something that will fit the wire size I have. Thanks!
Very nice! I have the same generator in a shed that I just bought over the summer. I installed a duel fuel kit so I can use propane also. Propane can be stored long term and easy to stockpile in case the you know what hits the fan. ✌️
Very cool! I've thought about it!
Nice Shed , Better to have it and not need it, then to need it and not have it.
if you are running your whole house by code you do not want to ground the generator. your house ground will work fine. as long as you have house ground connected.
Thanks!
Been two years after wiring a Wen to my house with no power outages. Before that it went out several times a year. I'm just wanting it to go out for a few hours. Start mine up about every month just to charge the battery and hook my welder to it a few times.
Yeah, it's a good thing to start the generator every month to keep it fresh.
Good ideas! I found yours looking for ideas to build mine. Good idea to pipe out the exhaust. Good idea to make it ready for 50 amps. Good idea with hinged roof.
I think I'd be worried about the intake clogging with blowing snow in a storm. Have you had any trouble with snow in this design? I think I'll use a vented soffit and skip the air intake. I'd add wires for remote starting, and a battery charger.
No problems getting it clogged...haven't had the opportunity in a snow storm. I honestly don't think it would plug either way, at least in my situation and the amount of blowing and accumulating snow around the exterior.
I did find that the cold air intake directly over the motor is needed to keep it cool enough, especially in the summer.
@@OutdoorsEngineer Thanks, interesting info. Tough to balance summer and winter conditions.
Nice job. I have a Wen 875i and am looking at building something similar. I was thinking of a smaller more portable enclosure. Did you go with the intake and exhaust plumbing after doing testing? I am planning on having powerless cold air intake at floor and exhaust through the roof ceiling with as many sound deadening turns as i can get to the rear of roof. Hoping the heat rises theory will keep the generator cool. Most of our outtages are due to snow.
I went with the plumbing because i had built a temporary shelter at one point and it started over heating. I figured I needed at least the intake and it wouldn't hurt to get the exhaust out as fast as possible. I have thought about drilling holes in the floor so the attic fan would draw cool air from the floor across the generator.
I think the biggest problem is heat, and making sure that engine stays cool. Thanks for watching!
Thats funny how you mentioned when you have it you won't need it. A few years ago Texas had record low temps, in conroe tx it got down to about 9 degrees and 14 degrees two nights in a row. and the power was out for about 72 hours during this cold spell. In my opinion it was one of the worse natural disasters that has happened in the past 30 years. Yes hurricane season the power goes out but its usually warm outside we are too far from the coast to really get hit hard anyway. I don't have natural gas so I had no heat. So that prompted me to get a generator. Its been like 3 years and the power has not went out since. I know that northerners think this is nothing, but down here most people are not prepared for cold weather like that. Most people don't have generators and oil burning stoves for backup. because it usually only drops to about 30 degrees and the power is usually on.
I remember that! Wasn't it a big ice storm that did a bunch of damage and took out power? We lost tons of power prior to 2017 when I installed this generator. Now we've only used it once or twice since! It is a nice piece of mind though, just in case, and really isn't costing me anything except for a little bit of oil every year or two.
@@OutdoorsEngineer I guess it was an ice storm, and from my memory I was about 4 years old 1989 it actually snowed enough to turn the ground white. Besides that, it has never snowed that much in this area. The first night all I had was some bell peppers and onions and tomatoes. That was my meal, lol. The next day all the stores had empty shelves and I had like a few bags of chips to eat. I know other people in different parts of the world have way worse hardships to deal with, but this was the only real time I went hungry and was cold. Actually I'm a veteran and I have been colder but not as hungry during those 4 years, lol. So I have nothing really to complain about, but think about all the people that have young children and elderly, that was a real natural disaster.
NICE JOB on the generator shed and generator installation! Could you let me know what the "alert alarm" is technically called, and where you got it???? I'm talking about the "thingy" that lets you know when grid electricity comes back on??? Thank you Sir!!!
I got it on the good old Amazon. www.amazon.com/gp/product/B003KREORA/
#GOALS👍
Thanks for watching!
Cool shed...Make one for people with less time and less resources..
Nice setup! I just wanted to let you know that the "Amazon link" to the "Electric Mains Return Alarm" is the same link as the "Hour Meter"
Thanks! It should be fixed now!
Nice shed - but can't seem to figure out how you made the roof lift. It appears you cut the door header and it lifts with the roof. Does this cause the doors or front wall to be a bit unstable when the roof is open? Any details on how the front wall to roof construction was done would be very much appreciated.
Yes, the roof header is separate from the side wall. With the sheathing on the sidewall and sturdy attachment of the wall to the floor, I have had no issues with the walls becoming unstable. They are essentially rock solid. The header is attached to the roof and is just sitting on top of the sidewall, attached through the latches. It's been 5 or 6 years so far and no issues with it holding up.
Email also sent.
Awesome video and the first vid that I can see a noticeable noise reduction. what do you think of using sandbags for the outer perimeter wall?
Thanks! That is an interesting idea for a wall. I don't have much experience with using sandbags but I'm sure they noise reduction would be great!
@@OutdoorsEngineer you can even do a stand alone wall right in front of the gennie that faces your house. If you place it about 6 feet away from the front door of the shed, and if necessary, angle it so it blocks the sound heading towards your home. The theory is that the sound coming from the shed's front doors would bounce away parallel to your house
Do you have a wireless remote start or do u have to go out in the elements to start it?
Elements. But I have seen wireless remote start kits for them! Just never had a need for one.
The building is nicer then the generator
I just might be!
is it necessary to ground the generator when the breaker panel to the house is already grounded? Basically is it safe to double ground?
How many gallons of fuel do you keep on hand? Nice set-up.
Typically I have a rotation of 3 - 5/6 gallon cans that I work through for lawn mowers, etc. Most of the time I have at least 1 full can.
Great job. Have you lost power since making this video?
Thanks! Nope!
Wow what a nice job! Is that generator enough to run your air or heat?
I honestly haven't tried the A/C. It does run our well pump, and looking at the power requirements for the AC, I'm pretty sure it would run the AC as well. It has no troubles with the furnace!
@@OutdoorsEngineer I had a generator that was a little less powerful than yours before I got my Kohler standby, and it could not run my air or heat. The initial draw was just too much apparently. So of course our power went out on a cold winters day. It was out for about 6 hours. That’s what made me decide to get a larger Kohler standby. Just something to consider. But again, it looks really great. A great piece of engineering.
Can i ask sir? Is it noisy at the back of the shed, where the exhaust fan placed sir?
Yes, there is noise st the back of the shed. I have it aligned for the back side points away from our house.
Ahh. Thank you for your response sir
what type of insulation did you use?
Just regular kraft face. Probably not 100% the correct stuff but it is working so far and its been a few years.
good job ,sir i am trying get my Generator video on you tube i think it will be a good one
I know this was a time back but do you know about what the costs were for all the parts to make this shed including the fans, exhaust etc. I realize prices have gone up but wanted an estimate. Will prob buy the plans ... got a genny on order....
I honestly don't know at this point anymore, it's been 7 years :). It really depends on what siding you choose to use.
Great job man 👍 I have the cat 8000 wanting to get mine permanent. What type of insulation did you use in your shed ? Thanks liked 👍 and subscribed 👍
Thanks! I just used regular residential insulation. Not sure if that is right or wrong ;)
@@OutdoorsEngineer looks like it is working out great for you.👍 I don't think right or wrong. Only done and working matter. And your shed does both 👍 thanks for the reply
I would bet that a 4000 watt would run almost everything in your house that you would want, for half the fuel consumption.... these big 9000 watt generators are good for when you want to run big loads, but probably better off running a 4000 watt most of the time, to save fuel. Fuel can be hard to get in an emergency...
Agree. I don't really see a need for that kind of wattage either.
If you want a 230v output, which you really need if you want to connect to your main panel, generators don't seem to have it until they are 5000 running watts or greater. I just bought a Champion 100519, it seemed the best option for people who want to tie in and want to run more than a refrigerator and a few lights but less than a whole house.
@@jshepard152 If you live down south, you really don't know how much you miss your A/C until you don't have it for a while, sometimes even days. Yes, hot water is a luxury when you want to take a shower after you've been sweating through a 4-day outage, but it is nice to have. 6½ gallons of gas will run my 9500W generator about 9 hours with the A/C running @ 78°. I can also shut it off for a couple hours at a time and restart it with a remote which is nice. With two refrigerators and a freezer, a 3500W gen is pretty much used up. The 9500W and a few more gallons of gas lets me A/C my house. For me, it's worth the upgrade.
@@freed6343
Makes sense I guess. I'm at 3600 watts on my generator. I only use one fridge and that's 1000 watts, probably less. Microwave would be infrequent for me and I could unplug something else for a short period if needed. I have propane for heat but still have capacity for a space heater if I wanted. If I really needed AC I'd probably use a window unit in one room only. Hot water in large quantity is something I'll just have to live without. But to each his own.
Nice.... but if I were you I would upgrade to an inverter generator, because those "worksite" generators will over time shorten the life of any sensitive electronics, which a lot of people don't actually think of as "sensitive". Pretty much everything in your house nowadays has some type of control board in it that it's lifespan will be shortened by a dirty sine wave, and fluctuations in the cycle (60hz). Even a furnace, you don't think about it, but unless it's twenty or thirty years old, it has a digital circuit board that can suffer from premature failure from dirty power. And an added benefit, inverter generators are usually much quieter.
The dirty power this gentleman is talking about is known a THD total harmonic disturbance.
Most modern control boards need a Total Harmonic Distortion of less than 5%, most non inverter generators are 12-20% THD
Nice shed, bur right now it would cost over 3k in lumber
For the most part, lumber has returned back to almost normal, if I heard correctly. It's the rest of build materials that are expensive.
Great shed, fantastic job!!! What are the base dimensions?
Thanks! Overall it is 4' x 6'
Plans are available: in-the-northwoods.com/product/genshedplan/
Love it, but I’m going to build mine that you can walk in and have shelves…also I have solar so I need a battery/generator room with ability to use as small
Shop to do basic maintenance on the power system
Sounds like a great setup!
Thanks, not built yet…and thanks for your video to give me some interior ideas!
Why do you need an exhaust port? Won't the exhaust go out of the box with the fan?
The faster the exhaust leaves the better. You are also adding extra heat that is easily plumbed out using the exhaust port. Plus, newer generators may have a CO detector on them, and if you dump exhaust directly into the shed, it'll shut off due to the CO safey mechanism.
what intake fan did you use?
I used this one: www.menards.com/main/heating-cooling/ductwork/booster-fans-accessories/corded-in-line-duct-fan/db206c/p-1449099006884-c-1453749027449.htm.
But you could probably get away with somthing like this too: amzn.to/42v75xi
Did you connect the exhaust to generator with magnets? Maybe my eyes arent so good, but i didnt see a cooling fan, just an exhaust fan, im i wrong? Overall, very nice work...
I just used some small self tapping screws, similar to rain gutter screws.
There is a cooling fan inside the metal duct. A 6 inch online duct fan.
Hi, what type of acoustic foam did you used and the thickness?
No acoustic foam. Just regular household insulation
@@OutdoorsEngineer Thanks
