@@lawnpro979 I had to stare at a photo to remind myself (imgur.com/a/zr5HKag). The sides and back are 2x8s I believe. The sides were cut down to create the slope. The connect to a 2x4 laying flat on the front. The rest of the beams are 2x4s cut on an angle and notched so it and the flat 2x4 rest on the top of the wall framing. The roof is then covered with 3/4” plywood, felt, and shingles. It’s at least 100lbs.

@@cheetahb5 Ok thanks, WOW I bet it is heavy!

@@lawnpro979 yeah that’s why I had to get those two gas assist struts. And they’re rated pretty heavy.

@@cheetahb5 yea. I understand,,,, I got the front of mine fished today and will be completing the roof tomorrow, or hopefully, GOD it's hot here in TX! Were in Bellville

@@lawnpro979 oh yeah, any sort of construction when it’s hot as hell sucks to no end. Good luck!

@@ourtexasfamilyvideos62 yeah the closed frame really cuts engine noise down. The preponderance is from the exhaust, hence why I ended up adding that muffler. Amazing difference.

@@kurtauerbach5883 I’ve been meaning to get a remote thermometer for it so I can monitor the inside temp.

Thanks! I believe this is the one I ordered for the shed: www.homedepot.com/p/iLIVING-10-in-Wall-Mounted-Shutter-Exhaust-Fan-with-Thermospeed-Controller-65-Watt-820-CFM-Silver-ILG8SF10V-ST/316859554

I don’t have specific plans. I have some sketches I drew in my AutoCAD with dimensions, but nothing formal. If you’d want to private message me your email, I could send what I’ve got to at least get you started.

I’ll have to dig around on my computer to find where I got that one.

@@cheetahb5 that would be great if you find out, thank you for your time. Nice job on the generator box 👍🏻

I have the sensor completely disconnected. I designed the exhaust so I can easily unclamp the pipe and remove it in order to take the gen out. Where it sits now, I think I can actually do the oil change without having to move it.

Is yours an open or closed frame gen?

open frame@@cheetahb5

So the generator itself has a large blower internally that sucks air in and blows it out the side of the frame. So I have one duct taking that air directly outside and the extra air I found around the muffler is being directed to the fan which blows it out the backside of the shed. so the gen fan pulls plenty of air in.

Yes. So I discovered that the exhaust fan on the gen not only exits from the port on the side, but also from around the muffler area. So the curved duct directs that exhaust to the fan so I didn’t have to try and duct it out the side like I did with the main exhaust.

Thanks!

So I have 2 exhausts: one for the engine combustion exhaust (tail pipe) and the other for the engine cooling fan exhaust (flex duct). If you watch the updated video, you’ll see I added a bit of extra ducting to redirect another part of the cooling fan stream towards my exhaust fan. The intakes for the gen are located on the ends and are fed by those big louvered sections in the side walls. For the tailpipe exhaust, I got an adapter (1.5”ID to 1.5”OD). The ID end slips over the gen exhaust pipe after you take the spark arrestor off. I clamp it with a 1.5” exhaust clamp. I them fit a 1.5”ID flex exhaust pipe over the other end of the adapter and secure with another clamp. Then I run the flex pipe out through the side wall.

Watch the update video. It’s significantly quieter now. It was the best spot that worked for a structure like that.

@@cheetahb5I understand; I wasn't trying to be a smart ass because the shed was built like a home; beautiful. You have great skills; I am envious.

@@mannys4036 thanks. No offense taken. It was louder than I thought it would be when I did the first video. I realized the majority of that noise was the exhaust, which is why I went back to the drawing board and worked out the muffler setup. That worked great. The rattly noise you hear in the second was due to trying to use a concrete form as an insulator for the pipe in the through-wall fitting. It broke and the pieces are what’s rattling. Those are gone as I realized the brackets holding the muffler hold the pipe centers as well. I just stuffed rock wool in there since it’s fire proof. Much better now.

See the update video. I added a small muffler which significantly quiets things down.

I would have dug out a hole and buried the whole generator underground to get rid of all that noise pollution. I would have like to hear how much you can hear it inside.

@@mannys4036 With the muffler on it now, I barely hear it inside. When the AC shuts off and the ESC ramps the engine speed way down, I don’t even hear it. Up in my bedroom, only the faintest of base. The update video was running at half load, more than what I ran in the first video: th-cam.com/video/gAJTZCzZnao/w-d-xo.htmlsi=hOh6NyqHjd7O4eCS

Thanks!

A regular open frame generator yes. But this closed frame inverter has specific intakes and a specific exhaust which is being vented overboard. I could see more of a concern if this was say the primary power source for an off grid place, but when being used very frequently for short power outages, there doesn’t seem to be much in the way of a longevity impact.

Im not a good judge of distance 🤣

Check out my follow-on video. Much improved.

It can but you have to vent it properly. Since this gen is a closed frame, it has its own internal fan to pull cooling air in and expel it out the side. That’s why I duct that exhaust outside and provide large intakes on the sides of the gen.

Nah.

SSSSSSSSOOOOOOOOOO, he could of done cheaper & better to just run open tubing ( flex ) maybe underground to wxit at another location, thus NO change in back pressure

Thanks! Yeah I think the roof is over 100lbs. But I had the shingles laying around. Next tornado, I'm crawling in that thing. It's like a tank.

Thanks! Took a lot of design/redesigning on the fly.

Got it on Amazon. Has sensors on the main lines in my breaker box and sends data to the receiver so you can see the total load in the house. www.amazon.com/Efergy-4-0-Wireless-Electricity-Monitor/dp/B001Q1G4WK/ref=sr_1_31?crid=WZIW1BN84ZJZ&keywords=Wireless+power+meter&qid=1690948046&refinements=p_36%3A1253531011&rnid=1243644011&s=hi&sprefix=wireless+power+meter%2Caps%2C140&sr=1-31

I just sketched a design and bought the lumber at Menards. Pretty much everything was from there except for the exhaust fan which I ordered off Amazon. There are tons of those. It’s a 10” shuttered exhaust fan.

That gen was $2k. I built the shed for the additional weather protection and security. I prefer to keep it as unobtrusive as possible, hence the additional sound mitigations. All inverters this size have about the same noise level. I just wanted quieter.

Smart move. Makes servicing the gen easier too since it's at a comfortable height.

This is the monitor I use: www.amazon.com/gp/product/B001Q1G4WK/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 Hindsight is a bit 20/20, but the idea was with it running, it pulls additional cool air in via the two end vents which will help further cool the gen. The layout of these gens makes it a bit more challenging to get a good airflow setup.

​@@cheetahb5So, What is your dB at outside muffler ❓❓

@@Honestandtruth007 unfortunately, I don’t have a dB meter so I couldn’t tell ya. Based on what I’ve heard in other videos, I’d hazard a guess at upper 50s/very low 60s

With a closed frame gen like that, the exhaust air flow is significant in order to cool the engine. And it comes out quite hot. It would cost far more to make the shed bigger and put in more air intakes and more exhaust fans and that will just make it even more complex. Plus, the gen will be sucking in hotter air into its cooling intakes which will reduce the effectiveness and could lead to potential overheating, even with wall fans. Best solution is to dump the heat outside.

This one is a Harbor Freight Predator. It’s actually pretty quiet. This video I kinda did worst case where I had about 50% load with the ESC turned off so it was revving at full speed.

I used my AutoCAD to design the shed to fit the gen. The shed is 51” deep by 56” wide.

So I was running it without the ESC on, which makes it louder. I ran it recently with the ESC on and it was much quieter. I’m looking at adding a small muffler on the exhaust to help quiet it more.

Way too loud,mine is about 79 out of box

Thanks! It was a home grown design. Are you referring to the metal pipe above the small hood? That’s the engine exhaust and the hooded one is just a cooling fan. The intakes are on the sides of the shed, so I think they’re far enough away.

So I was running with the ESC control off in the video, so the gen was running at full rpm. Recently I ran it with ESC on and it’s much quieter. I’m thinking about adding a small muffler to the exhaust which will cut a lot more noise.
