Very nice, only one surgestion is to rubber mount the inverter to help with vibrations. I had one that was solid mounted and the vibrations over time ended up cracking the printed circuit board in side. But other than that excellent work.
Jim Miles Thanks Jim. If you look in the video, you will see 4 thick felt pads that I used when mounting the inverter to help dampen the vibrations. Foam rubber would be even better.
Remarkable build there! Slick use of part's.
I just love proud people.. "that I built from SCRATCH... and steel bar that I BENT BY HAND!" 😁... great job here!
Thanks for watching!

yeah well he had tools..hand tools..🐨🐻
I didn’t think anything of it. Props to him for the great workmanship 👍

All but the welding most competent people can do.
Simply amazing, true workmanship.
Great job!
Jeno Wagner Thanks! I have a couple other videos with this inverter generator setup.
ill check them out!
I use the same *small generator-battery- to inverter* system to power my house- and without wind or solar- it dropped my electric bill from $170 a month down to _seven dollars._ This _works._
BULLSHIT SPAMMERS
You are getting *ripped off* by your *utility companies.* I hardly am the only one making _that_ observation.
Thanks for watching!
so that setup costs around 2$ an hour to run so you only had it running for the total time of 3.5 houers that month.
A twelve-hundred watt generator, at _today's_ gas prices costs about _thirty _*_cents_* (American) an hour to run.
Such a nice setup. I’ve never had luck with Tecumseh engines. I have replaced the carb twice on my root tiller. I’m repowering it soon with a Honda clone.
Find a Briggs and Stratton mower with a broken deck and repower it.
Hi Stephen. I never had a problem with the engine. It ran great for the 5 years I used this system. I only paid $105 shipped for the new engine.

Thanks. This will put to use an old reliable mower and a high input alternator I got off a GMC maxi van.
Have fun making it!
Dude, you have too much free time on your hands, LOL. But, that setup and your workmanship is for the ages friend. I love it.

Upgrade to 200+ alternator and get a 3k inverter.
Love your video
Nice build quality. Two small things come to mind. 1) You would not have had to isolate the generator ground if you had mounted everything to wood instead of steel plate. 2) Your belt underneath doesn't have a lot of contact with the generator pulley, maybe 90 degrees of arc. Putting the tensioner on the inside would increase the pulling traction without adding stress to the belt. (think like using a smaller pulley on a supercharger, you need more surface area on the belt)
I changed the tensioner since this video was made, and there's much better traction on the belt now. :-)
Wood rots, it breaks down.
plastic then! @@KeyboardBuster
fantastic work, that is the most unique $1200 generator I have ever seen.
Paul G No, parts cost around $425
Yes it is very good! Only one little thing is the tension wheel is to far away causing power loss
Hey 9 out of 10 is very good!!
Really professionally made. Looks like it came from a factory.
Matthew Nelson Thanks Matt. :-) Be sure to check out my video playlists and share.
@brodie1709
No, I start the engine first, then turn on the alternator. It will not start under a load.
Just recently stumbled across your video and like the idea of it. Thought about using the old riding mower my dad gave me sincecthe transaxle went out for something similar.
You could mount a 5 gal gas can on the end of the frame and run a fuel line to the motor. Would be better then filling a factory 1/4-1 gal tank every few hours. Also if anybody needs to run high amps (100+) but don't want big bulky wires then check out Silicone Wire, 8 gauge Silicone Wire can handle 200 amps max.
After 8 yrs can u still reply me pls i will be happy
Worlds heaviest 1k generator. Looks good bud 🤩
Outstanding work. Very cleverly done.
Thanks Jim! I used it for around 5 years, then I moved and sold it. Be sure to look over my extensive video playlist below for other videos of interest to you, and most importantly share my channel with others.

I like your setup. Is no fuse to protect the alternator ? Overall you did a nice job .
Great video. I made mine using a 3/4 inch HDPE base and then used large fender washers to secure it to the base. I use all stainless steel bolts & casellated nuts & cotter pins & lockwashers. Stainless steel lasts forever. HDPE can last 20-30 years if left in the sun. Avoid plywood or steel plates. Steel is too damn heavy. a piece 3/4 HDPE is alot lighter, and will never rot or rust. HDPE can be bought new or salvaged from old boats.
I like HDPE(starboard), good stuff!
well done, i recently acquired a honda gx160 with a trash pump on it, no use for trash pump, want to convert to genny.
This is cool man. Props on being able to weld aluminum!

That's not aluminum it's galvanized steel conduit
Nice job! Where did you buy the inverter (power converter)?
Bought it in 1994 from JC Whitney.
Very nice job!
Thank you!
I love your building clean lines . . . .very nice.
Thanks! Glad you liked it. Be sure to rate thumbs up, check out my extensive video playlists, and share. :-)
I built a similar one and they work fine. I had seen it at a racetrack.
LOL. Go cart.
@@electronicsNmore ???
Though you were joking about it looking like a go cart.
@@electronicsNmore lol! Nah I had gone to a drag racetrack and I saw 2 of them there me they use them to restart engines or charge batteries because some of them don't run alternators on their racecars just for a quarter mile race to reduce load on engine. They are easy to build just need patience.
@@electronicsNmore I can look at something once and memorize what it's made of and build stuff. Ttyl, take care.
That’s actually pretty sick.
Great work! I have an older lawn mower with self propel and I attach a sending disc to one of the front wheels, but would like to make more uses out of it. what type of inverter did you use and cost?
Years ago they were expensive, but a 1200-1500w is ideal. If you need a link, just ask. Thanks for watching!
Very impressed. Your a talented guy for sure. Well done
l like those engines ..better than Honda..imo..
Great design and build..
Thank you! Be sure to rate thumbs up, share my channel with others, and check out my video playlists.
Do you still have it? Ever try to weld with it? Nice build.
Well being proactive instead of being lazy and clear the dead wood and brush if you choose to live in a harsh environment.. Good Luck Dmy.... HA HA
If you rotate how you mount the alternator by 180 degrees you could use less length for your cables and wouldn't have needed to cross them. It probably will not make a big difference, but its just my OCD side. 😁
It is pretty great setup. :D
did have efecient? did inverter generator using 3 phase convert to dc and step up to single phase again ?
Nice setup. I thought about building a similar one using a small horizontal shaft engine from harbor freight.
+Jeremy Lafary
They're certainly fun to make. :-) Thanks For Watching!
that plate steel makes it super light weight! xD
I made it heavier so the entire thing wouldn't vibrate and move around under load. Thanks for watching!
Really Nice Job !
Thanks!

@@electronicsNmore yes sure
Very nice construction but just a warning... Those delco-style alternators can be damaged if you run them without 12vdc wired to the BAT terminal on the rear.
+dontmesswiththeman
Not true. After 5 years of use, I would have noticed something. Disconnecting the wire off a (1) wire 10si alternator will not cause any damage. All that will happen is the rotor will spin without any current being supplied to it. I have used this alternator for years w/o any issues. I made my own regulator for this alternator which works much better. I have a video showing all the modifications.
Thanks For Watching

That about somes of me up!!! I just finished showing your setup to my friend who also shares our interest, He is also a welder and all around jack of all trades. He liked hte gen setup. Let me tell ya, if he complimented it, you have REALLY got something!
How do you control the field input of the alternator? Also, don't you need a voltage regulator between the alternator and the battery?

Now that is a beautiful setup.
DIY Solar and Wind Glad you liked it. :-) Be sure to check out my crank generators as well. Thanks!
Like your set up, just wondering why a 1000w is that the highest you can go with that alternator or can you go way higher than that. Tks for the videos.
You can go higher, but the pulley ratio would need to be adjusted to handle the inverter under load. Thanks for watching!
Ok thanks for the information good to know.
That is a professional build !!! Great job
alan koza Thanks for watching Alan. Be sure to check out my Automotive/mechanical video playlist, and Useful Tips video playlist also. Please be sure to share my channel with others. Thanks!
Excellent next would you consider making a wood gas device so that if there's a shortage in fuel that wood gas can be used instead.
Not wood, He probably make one to run off coal.
Can you make a parts and costs breakdown in video description? Good video, good job
Hard to do because the engine and alternator may vary, as well as the tensioner/pulley used. Thanks for watching!
I have a old alternator and some lawn mower engine thought this would be good use for it now seems like I'd be better off buying a used generator
does the motor ever kick back when you try to start it? or did you add some kind of extra flywheel to the engine. because any lawn mower engine that i have had without the blade on it would kick back when you try to pull start it.
Great job man, if you ever build another one you might try a couple capacitors between the battery and the inverter, like the 1 and 2 farad models used for 1000w+ stereo systems, i think it would eliminate the bogging, im curious to see if that would work
Thanks. I have another video showing a modification I made to the alternator's rotor. It worked like a charm when using heavy loads. It was made shortly after this video.
I was thinking about doing this, but I did have a concern and that is duty cycle of the lawn mower engine. Now I have not done the research yet but would guess that the lawn mower is not ment to be run for the same lengths of time as an actual generator? Maybe it is completely fine?
No problem at all, just make sure you use good quality oil(preferably synthetic). Be sure to look over my extensive video playlists for other great videos of interest to you and most importantly share my channel with others. Thanks!
@@electronicsNmore can do
If you bought the components new, how much would they cost compared to a 1000w generator? I realize you could shut the engine off and go for a while operating loads with the battery, which is an advantage over a store bought generator.
I didn't pay that much for everything. The inverted I had laying around, the engine was $100 shipped, and the battery was $75.
Yeah, that's a good deal. I have various components collected over the years and now not used for their full potential I could fashion to do similar. You've given me ideas for their potential.
For $89 you can buy a 900 watt generator at Habor Freight that is ready to use.
@@FloryJohann sure runs all the time horrible fuel consumption junk than if rated at 900 watts might deliver 300 watts lol
@@ronaldbrown9638
A 6.5 hp Tecumseh engine would use more fuel than the 2hp harborfreight engine anytime.
That 6.5 hp e ngine is over powered for that 1000 watt prowatt inverter and for the alternator.
Actually those harborfreight generators had a good rating back then and they where putting out 800 watts on continuous usage. They got replaced by another model since and cost more.
I like the concept of incorporating a inverter and a battery, but the battery need to be cycled or it will die early and batteries have a lifespan.
I'd want the smallest engine I could find with a large sprocket. On the alternator use a small sprocket so u could run the engine at the lowest idel possible. That way a gallon of gas could last much longer. Is this possible ?
A gasoline engine is more efficient wide open.
Thanks!..:-) I see your into the same things I am...Survival/guns...etc.

Doesn't everything want to survive ??? Lol. ;) good video , well presented
Nice work, thumbs up!
Thanks! Many great videos on this channel, so be sure to check out my video playlists, rate thumbs up, and share. :-)
I am thinking of building my own generator with old mower engine. Edit: the engine was on a self propelled mower with a drive pulley.
@lunarrn Thanks, using it now after the Hurricane.
Nice job. I literally built the same thing. Had a 3.5 Briggs and it was made for a self propel so it had a very belt above the blade. I easily bolted it and an alternator together. Engage ran perfect. Then I fielded the alternator and it died. . Do you think it's from what you were explaining at the end of the video,? Or was 3.5hp not enough for 120 amps?
3.5hp is kinda small, and yes, if the engine won't crank over, you could be experiencing the same issue. Thanks for watching!
You could generate way over 1000 watts with that setup. Or inverter 1000 watts . Right ?
Strictly inverter output 1000W, but I could use larger. Thanks for watching!
Very impressed dame good job

Hello sir Can I know what materials you used to create that for Research thesis product in my college degree
This is awwesome. nicely done.

You'll probably like the video below.
th-cam.com/video/s1omETrT54w/w-d-xo.html
what size is your pulley under engine shaft. it looks like I have same size but just be sure. Give me radius measurement, I have everything on hand except for frame. I have self propelled Yardman 6.5hp lawnmower that have spring loaded starter system ( no need electric starter), first time pull start the engine and let it run then cut off, engine winds up spring before dies out. Then press lever and it release energy from spring to start engine again without pull start. it's so damn cool. Former owner left her mower to me even I have my own Toro 6.5 hp self propelled and bought John Deere LT150 riding mower. So thought why not rip off engine from Yardman frame and modify for generator. Am thinking of getting 2 KW or 5 KW inverter. I can go to Pick N Pull to find 80 amp Alternator size of hand (ford fiesta and several small cars have those because smaller alternator, less drag from "electric braking" from power load). Two 12v batteries in Parallel would cover enuf juice to run 5 KW inverter while generator running, charging batteries. Just wanted to have enuf power to run lights and ref during blackout. I can buy 10kw LF inverter but am afraid that it won't be enuf to power entire house due to actual wattage limitation ( says 10KW but actual limit is 5KW, Chinese made).
so let me know of ur pulley size under engine
Hello. I no longer have the generator. I moved back to the USA, and sold it.
Nice. Very nice!

Nice work, I think I'll make one too.
Thanks. It was a fun project.
Great build !!
Thanks James! I had 5 1/2 years of very good, reliable use out of this generator. When I left the Bahamas, it was too much money to ship back to the states, so I sold it.
If it wasn't flooded from IRMA I'm sure someone is using it.
It's probably destroyed by now. I sold it almost 2 years ago. I got $375.00 for it, which isn't too far off from what it cost me to make, minus my labor. Most Bahamians don't take care of things. I'm sure it was left outside in the rain, and all rusted up by now.
Wow, very nice job! How long did it take you to build this?
hey are you still here
Although this is a nice set up, I am making one that runs a little differently, mine I am using an electric mower motor with an alternator with a small solar panel hooked up to it, then the battery and invertor hooked up to it...its a great set up that requires no fuel...hopefully it works...
+Jacob Yisrael
Based on what you said, it will not work. I'm just trying to save you a lot of time and money from trying it.
Thanks For Watching.
electronicsNmore
um no it will work sorry but I have seen it already working
Jacob Yisrael
Good luck with it.
+Jacob Yisrael gotta link?
Joe Yocom
there are plenty of videos right in here that shows it, just do a search
Maybe next time you would show more on how it works vers all the wasted time talking about how the wheels work and whether or not it is riveted on whether or not you hand them to steal. It is extremely nice built I'm not putting you down on that just wish you would spend a little bit more time
It was the 1st video I ever made. LOL
Looks great man.
Thanks
If you got a bigger battery you can turn this into a hybrid generator using solar panels with a charge controller, using primarily solar power when its sunny outside and the engine when there is a lack of sunshine
Wow very cool
if you have the parts laying around great idea but a 1500w 4stroke gas generator is less than $200 and runs twice as long on a gallon of gas.
This video was made 10 years ago! LOL
muito bom seu trabalho
you could run four of those alternators with that engine
Good luck with that. LOL. Try it out. When a load is placed on the alternator, the shaft becomes very hard to turn.
Well done.
good job! inspiring.
IamTheTuna Thanks For Watching
what size pulley do you suggest
You need to know what engine your running and what speed the alternator is rated for. Most alternators produce max power around 5,000RPM (will do 8k but you will burn it out) and most engines run around 3,600RPMs so to get them to match you need a pulley ratio of 0.75:1
he didn't mention how much it cost to build as opposed to just buying a generator or buying an invertor and attaching it to your car. I agree it's well built
It cost me around $400. Thanks for watching!
The point is to teach people how to make one.
Impressive

That's genial bro
great but how will you know NOT to over charge the battery?
The alternator takes care of that.
What size alt power wire are you runing
I think it was #4 or #2 stranded copper.
@@electronicsNmore ok cool
I thought so
Ty
may i have a idea as to what the total cost was ?
More than just to buy normal petrol generator from fb 😂

Very nice
Thank you!
Looks really solid and well made, considering how these usually are.
But having a gas generator running an alternator, to put through diodes, to make DC, to invert, to make AC, really bugs me.... There doesn't seem to be a good way to do this with an automotive alternator designed for low voltage output.
I can assure you it worked very well for years, especially after my mods. Thanks For Watching!
Nice work buddy. You rekon a 5hp B&S do the job too?
If the pulley ratio is right, it should be fine.
It has more todo with where you live and how much power you're looking to get out of it. I have a few of these. I've built 24 & 48V systems to do every thing from jump start my equipment to running a 10kW Con/30kW Burst. An engine loses about 3-5% of its power per 1,000ft of elevation. at 1 mile (denver), accounting for all the losses in the system (10% for the pulley, 50% for the alternator) max you can run is about a 1.5kW Alternator or 120Amp, One guy commented below about using a audio system capacitor... only ways to go if you don't have a battery in the system. The alternator will burn out quickly with out it!
How is ratio of the motor or what is the minimum rpm for the alternator
Thats awesome
@myvideoisonutube ah thanks, that should elminiate the problem i have had when i tried this.
i had a question how can i use two battery on a scooter and make sure they are charge
Why do that?
Dumb question
But 100amps x 14.7 volts dc isn't 1000 watts it's 1470watts ??
I am making the same kinda thing
I'm just gonna use a 160 amp gm alt
But cool job
The inverter is only 1000w
