The more recent EG4WP has a better BMS and can handle larger surges of inrush current. 200 amps continuous and surge to 400. I used one for my lawn tractor project. I don't think you can get them anymore. The other "golf cart" 48 volt batteries are 2 times as expensive. I wish I had bought 2 more when the were 1000$ since the other brands are $2000 and up for 105 amp/hr 48 volt, 5.2 kWh batteries.

Nice demo

Youre asuming a power factor of 1.0 wich is never the case...

Hi there First of all, I love your work 👍👍👍 One comment about your calculation or kWh/gallon (21:50'') I believe your home made generator is ways more efficient than you tried : Remember your engine generates around 5kwh And with even 3kwh you were ways of stalling. If you feel you have the time, a bigger alternator or a 2sd one in parallel could bring you above 3kwh ( at least 30% more efficiency per gallon which would bring you to 5.5kwh/gallon if not more) Let me know about your thoughts, and sorry for my English : I am french 😋

Good work! How did you secure the threaded rods in the ceiling? Did you use threaded rod ceiling flanges?

Great job!!👏👏

Where a been Dave ?

David - thanks for the video's. These Schneider low frequency inverters are great - but expensive. I wish I could run my house on one inverter (new house with 5 ton ac) but that is probably only wishful thinking. Stories out there about software glitches and poor support may be old news? Tough to beat two 6000XPs where you could throw them away every 5 years and still be money ahead. Or do you think one Schneider could do what two 6000xp could do?

Wonder how this could work with a automatic generator start system

Is there any way I can ask you a few questions? I set up a Chevy volt battery to a Trace sw5548. Just need help with bulk, float, minimum set points.

Hello, I have a solar installation with 3 inverters 5 kW mounted in parallel with a total single-phase output of 15 kw but I have a three-phase public network subscription of 15A per phase, I would like to know if it is possible to make the network injection of the 3 phases with a phase by inverter on the prallèle mono

what about freezing temperatures? will the solar damage your battery?

Great video..tq Just thinking out loud, Instead of petrol do you think we can run this via a battery and still charger the charger..full loop?

nice but not so precise efficiency comparison, you can't compare gasoline with diesel using only volume parameter, it's much more complex, but thanks for the video, it's great! I would like to know about thermal integration, using the heat from generator to warm water or something else, greetings from Brazil!

FIND A UKRAINE LIKE COUNTRY TO BECOME LEADER OF AND DEFEND LIKE ZELENSKI!

Thank you for this video ! I love micro heat storage system for home and apartments ! I d like to do a system like this this too !

lmao aluminum electrodes

Lo único malo es que ese tipo de inversores tienen un consumo muy alto 70w u 80w y eso al cabo de 24h son kw de perdías

Una pregunta porque te has decantado por ese bms ??

Pricing this out, I’m wondering if you bought the Schneider Inverter XW Pro but then went with non-Schneider everything else, would it work?

How many mins in today's 😅

Let's get a Discover AES Rackmount in your hands for evaluation!

4 gallons of gas to run a fridge 24 hours

Someone needs to make a direct DC quiet battery charging generator. Going through the inverter is inneficient

BMS on grid... Then the grid crash! Oup! no BMS

I have a question for ya dave. you said these have a built in charger. i was wondering if it functions like a transfer switch when the battery is full directing its grid power to the load? i dont have any panels but just need a UPS back up for my whole home. this inverter seems to have it all. im hoping it has a feature like that.

interested in a fuel economy test , very interesting test & wicked results. Also very informative with parts needed& where to get them also.

Is this unit still working ok for you

Hey David , what you mean can I use an 48V Alternator with 11kw and 480ah for my battery pack 32x 320ah 3,2V ? Or is that to strong? Greetings Oliver P.S. great videos I love them!! 👍

I was considering buying the Growatt 3500 Watts inverter/MPPT charge controller at 48V, but after talking to an installer who has experience with Growatt I changed my mind. He said that the inverter will shut down if the battery voltage drops below a certain threshold, but the MPPT will also shut off so the unit does not charge the batteries. He recommended that I get a separate MPPT charge controller and stay away from the All-in -one unit like the Growatt. Just saying.

Bro I wish I could be near u for I need a 3kva DIY LITHIUM BATTERY

Sir you did well , but can you make it run with out fuel?

What about heat buildup in the alt over a longer time running if it's running at a high output will it last

I wonder if you could keep the original diodes or AC to DC rectifier.

So much happened in that intro video i lost brain cells lol Bro went from teenage power tools to dad in 4 seconds.

Just found you video! Thank you for sharing your experience!

Buy a belt tensioner it will run any speed

Boil the black pipe in citric acid will clean it up

Can you make a bike generator +-200watt

That's awesome! You just confirmed proof of concept using a 12v automotive alternator could be configured to be a gas powered generator. Something i had only thought of building when i wanted a gas powered jump box. This project accomplished much more than that , of course.

But why ? Why would you take an alternator ? Those things are horrible, the have a really bad efficiency of about 50% or so. Instead use a big stepper motor, those should be about 90% efficient.

Question ❓, If they have a built in PV controller, why did you install the Victorian charge controller too.

Do you know how this battery is performing now...Still no issues? Thanks!

I know its a little late .. But how about an alternator intended for use on a Truck ..

They say it can't be done but those who say it can't be done or being interrupted by those who are doing it now I am wondering instead of using a gasoline motor what about an electric motor. Can we get that to pull off of an electric motor where it recycles off of the in a 220 volt motor motor that will turn the same RPMs is that that's needed for the alternator

change the alternator's stator to Delta from why connectionlp two double the output

David, I loved your project. By any standard it is a success. Reading the comments obviously you can optimise it in many ways, however, what strikes me as your project's greatest strength is that it is all a made from available parts. Arguably you could repair/keep this thing going in a zombie apocolypse! Anyone can go and spend $3k++ on something sophisticated, but can they repair and keep it going if their life depended on it. As a pragmatic engineer I say, if that was your goal then you 'hit the nail right on the head'. Keep up the good work.

how much can you sell it to me?
