I found it hilarious when you mentioned why try to be quiet when your neighbors are just making so much racket. I deal with similar issues. My home is in a neighborhood with homes very close together. I run a Westinghouse 5000w closed frame inverter generator to try to be as quiet as possible so not to disturb neighbors. What did my neighbors do when we lost power during hurricane Beryl?….Run a large open frame construction style generator that they borrowed from a friend out in the open 30’ from my bedroom window. Talk about frustrating!
In the event of a power outage you can't possibly have enough fuel stored to keep the house powered. Those things chug fuel. This is why inverter generators are better. They can rev up and down depending on the draw.
That lizard running up the wall distracted me! Lol
Job will done ✔️ sir
First time seeing ur chanel i love it you go into details but i wanted to see u start the generator
This was an update. There is a startup in the original video. Thank you for watching
Nice project. Just FYI, that, foam does not really provide a reduction or absorption factor in the frequency range where you need it. You need rock wool or some other dense material (not foam of any type) and air gaps or resonator boxes tuned to the right frequencies. Secondly, you want to reduce vibrating surfaces and open gaps where the sound escapes directly to the environment. Obviously, we all look to balance cost, effort, and time, so of course, all of these are just tips if you look to improve the design over time. SoundBlab here on the tube has a great example of an S tier enclosure if you are interested. Looks like an enormous amount of work though :P
Wow just when I start working on my shed
Yup…tons of variations. Just go with what you can or choose. I watched probably 15 videos before building mine. And still did things I wished I did differently. Just be safe.
Nice work ! I wonder if using some sound insulation on the shed roof/cover would help lower the noise even more.
That's an extremely dangerous setup. With all that flammable foam insulation. I built a generator shed out of solid concrete but the only thing I couldn't build out of steel and concrete was the door. I had a exhaust system with a 2 inch iron pipe through the cement wall that would make up with the exhaust port on the generator. Well this ran fine from 2011 to December 31st 2023. And then on New Year's Eve 2023 the exhaust must not have been perfectly lined up with the fort in the wall because hot Vapors ignited the door frame and cause the fire. This inside of a concrete strull with 1,000 cubic feet per minute industrial fans pulling air in and exhausting air out the other side so the generator is in the cross wind of the fans. The Saving Grace was that the intake fan was a slightly higher capacity than the exhaust fan so the air pressure in the room was higher and kept the Flames away from the generator itself. And the irony is I had run this thing in 95° heat in August without a fire. It was 34° and raining the night of the fire. I've since replaced that generator with a military MEP 803a diesel generator.
From what I understand, if your generator has a floating neutral for running the house, if you decide to use it for direct applications the ground wire connection does not all of sudden make it bonded. You need to connect the neutral and ground directly in the generator again. It needs a jumper wire.
One more thing I noticed. You have gaps all around your doors as well as nothing on the top. If you put your egg crates on the top that will help a bit, but more importantly, those edges where the top sits on the tops of the side walls is not only letting noise out, but it is also a major vibration point and creates more noise. Maybe run a strip of foam on those contact points of the top as well as the doors.
I didn’t even think of the weatherstripping along the top. That is a great idea.
What kind of heat buildup are you seeing on a hot day when running with doors and top closed?
So, if you are going to make the pad larger, Go in the opposite direction, away from the house. I did not see this video until after I made a few comments on the other video of this shed. You are supposed to be a minimum of 3 feet, and in some areas, code is 5, from the house. Unless the code in your area is different, (which I do not think anyone has less than 3 feet from the house), then it is best to simply drill 4 holes (evenly spaced) in the front (side farthest form the house) of the slab and insert some rebar dowels into them. Your dowel should be at least 6 -8 inched into both slabs. So, drill the holes and then fill them with concrete adhesive and insert one end of rebar into the holes and allow them to dry. Then build your new 3 sided form and pour your new extension. You may want to look into installing some anchors of some kind to attach and secure the generator to the slab, so that it will not move and disconnect the exhaust.
Also, don't worry too much about the aggregate showing through, when you add the other extension, that will be covered. Just be sure to mix your concrete a little longer than you think it needs to be. Some people may argue that water can penetrate where there is bare agg, but I'd only worry about that issue if you have any open agg on the top of the slab, and if it freezes in your area. But agg on the side like that isn't a major issue since there isn't any major weight on it.
Since you are making a larger pad, you can then make a double walled enclosure. Sort of a box within a box, or a shed within a shed. Just don't make the air inlets and air exhaust holes inline with one another, have them staggard, meaning have the air inlet of the inner box on the ends, but have the openings of the outer box on the front and rear. Then simply section them off so you are not mixing the two in the void between the boxes. I know you said you were not really worried about sound, since your neighbors also run their generators when you do, but any and all sound deadening is much appreciated by your ears, and the loudest generator is the one that is closest to your house.
At first I wanted a gen house. They are cool and look good. Did a cost/time benefit analysis and decided its not worthwhile to do it right in Florida. I just put a lean to on the side of my shed to keep it out of the rain if it needs deployed.
@@EeEric727 I did that at first too. But where the hook up to the house is and where I stored my generator was a pain in the butt to move in the rain and snow. So the shed made sense for me
@sa3key thank you for your time to create this video. You shared some good tips and tricks. I got lucky with the shed near the service panel. Maybe eventually I'll change my tune. Few yard space projects in the works.
When putting these in small sheds, why don’t you make a bracket or chock for the wheels to keep the Gen from moving due to vibration?
Actually a great idea!
Did a similar job to yours. Comments:
- If you want to properly soundproof your shed you need a combination of a sound barrier and an absorbant material. You have only the latter but sound barrier is heavy and not practical for the door and maybe the lid. There is nothing on the roof. Bare spots negate the work you have done. A crack or opening in the shed will allow the sound to escape. In my build I put curved vents on the intake and fan exhaust. since sound likes to travel in straight lines and is forced to go at right angles. I put adhesive window weather stripping on the floor to seal the doors and also the lid. Good soundproofing is expensive and can blow the budget so be careful. Think about a muffler on the exhaust.
I cannot understate the importance of good air flow. I hear comments from others like - it ran for 9 hours and no problems. Remember the cyl. heads and generator windings don't like heat and failure is progressive until it reaches the point of failure which will happen when you most need it.
In my case (Honda 5 kw) I installed a 16" ac infinity fan on the outlet rated for 3,000 cfm. to get the temp down to no more than 15 F above ambient. Get a remote thermometer and monitor inside temps. This will confirm if you have an inside temp problem.
Hard to see from the video but if you do not have vibration/ absorbant pads under the feet, then think about doing so.
You have an extended length of exhaust tubing. It radiates and conducts a serious amount of heat. Glad you wrapped it. If sealing the gen. exhaust tube end is an issue put some muffler cement around the connection. When you remove the gen for servicing it will easily debond.
I would consider also buying bimetallic high temp shutoff disks (normally open) and connect these to a shutoff circuit such as the low oil shutdown. There is an excellent 2 part videos on TH-cam and also buy these Shutoff disks (Ebay/Amzn) for a temp above the normal operating temp of your generator to protect it from say a fan failure and meltdown when it is unattended. These are cheap and I settled on 130 F. After install I tested with a hair dryer.
This is amazing feedback and I appreciate it. I am always looking to improve and tinker around. I will absolutely look into what you laid out and maybe do another shed update video.
It’s that time of year in Va, I will probably have to use the generator soon.
I don't know about your particular generator but my Duromax manual says to keep it a minimum of 20 ft from the home when in use.
I have the same generator. From my research on this generator, I believe the 20 foot recommendation is to keep the noise level down in the house.
Do you like this generator? I'm thinking between this and Westinghouse.
I do. I got this one in particular because there was a hurricane coming and the news was predicting power outages. I had just moved to the area and needed a generator in a pinch. This was the last one available at Harbor Freight. None were at Home Depot or Lowe’s. So by default, I grabbed this one and it has not disappointed. I did intend to use it for my RV which is also why I grabbed the size I did. But it will be used only for the house now. I do the maintenance on it myself and run it every couple of weeks per the manual. But I think you would be good with any generator you pick. Just make sure it has the watts and amps you need to run whatever you need.
Have you ran it for extended periods of time in 90 degree weather to see how it handles the heat?
@@taylorcampbell985 about 6 months ago I had to run it for 6 hours due to downed power lines. No issues.
@@sa3key awesome I’m in middle of making mine right now. Was gonna go with cement board and a 16inch exhaust fan. With the amount of heat it puts off. Plus we have 95degree weather during hurricane Season
Do you happen to remember how many bags ( approx.) of cement it took to make the pad ?
I bought way to many. But I am thinking it was about 20 bags
Thanks for getting back to me so quick. I'm about to get a shed for this and I am going to build a pad, but I wasn't sure how many bags to get. Usually I get to little and in mid project I have to run back down to Home depot. So at least now I have a general idea of how much to get. Thanks again @@sa3key
@@ronbrown4551 absolutely. Here to learn and help. I bought a whole pallet of concrete and returned what I didn’t use. That way I didn’t have to keep running back and forth. There are calculators online to help to. Just a simple google search and you input some measurements. If you use one of those, I would still buy a couple extra bags, just in case.
@@sa3key thanks I never thought about that. I'll check that out
Each 60lb bag of Quikcrete makes 2/3 cu ft. A 2ft x 3ft x 4" slab will take about 4 bags + 1 or 2 extra if your ground isn't too level.
Get an intake duct fan
I have been looking at those. I saw another video where a gentleman had one. Have been thinking about it
In the comments section.. .where's the "but your fan is too small" guy? Lol
I agree that insulation is unneeded after a natural disaster. We would have much bigger issues to deal with...
Enclosing a generator not designed to be enclosed is never a good idea, over time your investment will degrade your generator faster than normal.
Yes, it presents challenges but if you pay attention to heat levels and ensure the temp rise is kept at or below a 15 F above ambient you should have no problems. Most project builders ignore this but many manufacturers such as Generac and Kohler for example sell enclosed generators but these are properly engineered.
Remember too that these installs are for emergencies and see few hours and in that respect they are foregiving.
Need enclose the generator and secure it. It would be stolen during the night. My house a/c 4 ton was attempted to be stolen. Welcome to Florida.
Don't talk bullshit man.!!!
GEICO on your wall 🦎🤣🦎
