Welcome! In 2012, my wife and I built our own super-insulated home. The house is one and a half stories, which includes two lofts. To some, it would be considered small, but it's perfect for us, and is even larger than most apartments we have lived in. The house is so well insulated that we don't even need to run a heater, save for a couple months out of the year. Join us to see how we built it and what projects we continue to do!
As our channel and website (www.davidpoz.com) grow we will put out more energy and efficiency related videos. We are constantly meeting like-minded people along the way who have their own twist on energy efficiency, which is awesome; the online community is great. We have even done an interview with another energy conscious homeowner and hope to do more in the future.
Thanks for stopping by!

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?
The battery has built-in protection for cold weather.
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!

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?
Also why all the DC breakers on the PDP and so few Ac? Any small cottage I guess will be adding subpanels for house wiring.
Sure, my friend, Chris, did that with his system. He is using a Midnite-Solar brand DC circuit breaker box. Here is a video with his property: kzread.info/dash/bejne/lnh7ubuAiLOZhJs.htmlsi=vido8inacRirnvHU
@@DavidPozEnergy Thanks so much! He used the Schneider MPPT. I'm seeing the value as I watch your Schneider playlist.
How many mins in today's 😅
Let's get a Discover AES Rackmount in your hands for evaluation!

Someone needs to make a direct DC quiet battery charging generator. Going through the inverter is inneficient
I agree. There are some on the market, made for yachts. Far too expensive for me.
@DavidPozEnergy I've seen guys hook a motor up to an alternator but they aren't meant to charge a fully discharged battery either and the motor isn't quiet. Maybe if you got a tractor trailer alternator it would work better. This would help those Living off grid
Sure. I've done that very thing: kzread.info/dash/bejne/dYBsuZehmdPHfLA.htmlsi=849FU4J4uM_dHjyW
BMS on grid... Then the grid crash! Oup! no BMS
I'm not sure what you mean.
@@DavidPozEnergy Sorry it's my bad, I tough it was a kind of subscription that was needed to connect the BMU "to some higher level computer" on the web. 3:37 "so the way this type of assembly works it does not have a true BMS or battery management system instead it has this which is a bmu or battery management unit it's collecting data and then sends that data up to some higher level computer which would have been one Central higher level computer" Some car need a subscription to use heating seat or the sound system already installed in the car, it's a new type of scam. Sorry '-)
OK, gotcha. This module would have originally been built to be part of some large system. For example, I've seen shipping containers with hundreds of these modules. The shipping container might have one central computer collecting data on all the individual modules. The system as a whole is a BMS, but the individual circuit board is the BMU. I replaced that with a stand-alone 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.
Yes. Each inverter has a built-in 60A (240V) relay to allow the grid to pass-though. Using this as a UPS is very common.
interested in a fuel economy test , very interesting test & wicked results. Also very informative with parts needed& where to get them also.
Thanks. In Video part 3 I fine-tuned the fuel economy with testing various loads and RPM's.
Is this unit still working ok for you
No, the Mr. Cool stopped working and the company stopped responding to my e-mails.
Thanks was considering trying one but might try something else
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'm sorry, I might not understand. If you are asking about using a 48V alternator, yes, that would be easier than using a 12V like I did.
@@DavidPozEnergy Does the inverter have to be as big as the battery, i.e. do I need 3x 12kw inverters or does it just have to be as big as the power I need?
Just big enough for your power needs: Size your inverter to handle the loads. Then the minimum size of the battery is what can supply the current needed for the inverter. You can always make the battery bigger.
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.
It's a great point. Having separate CC and inverters gives you more flexibility. Personally, I set my low Voltage cutoff fairly high (48V) and never had an issue. I ran my house Growatts for over a year. However, now I'm running on Schneider equipment.
@@DavidPozEnergy I really enjoy watching your videos, especially when you opened the Growatt to show the inside layout and components which I am mostly interested in. I am an Electronics repair/service technician and like to see the electronics side of inverters to judge their quality. I look mainly for toroidal transformers, high quality FETs and Capacitors. Also if the circuit boards are coated with acrylic conformal coating to prevent moisture damage. Thanks for your reply. 👍
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?
No, the engine needs fuel.
What about heat buildup in the alt over a longer time running if it's running at a high output will it last
Check out video part 2, I ran several thermal tests.
I wonder if you could keep the original diodes or AC to DC rectifier.
I didn't know the specifications of the original diodes, also, I wasn't sure about the bridge between the high-Voltage and low-Voltage sides being a problem or not. In video part 2, I dedicated a few minutes to discussing using the original rectifier. I figured the method I used (separate rectifier) was a safer option with so many unknowns.
@@DavidPozEnergy makes sense
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.
Your are correct that an alternator is not the most efficient thing out there. I did this because alternators are easy to get used and cheap, and I always wanted to try one. I suppose if I had a big enough stepper motor on hand, then I'd try that. Note, this particular alternator is a bit better than average at about 70% eff.
@@DavidPozEnergy 70% for an alternator is not shabby. Thanks for your explanation.
Question ❓, If they have a built in PV controller, why did you install the Victorian charge controller too.
Each inverter has one MPPT charge controller built in. I have 3 solar arrays in my backyard (videos on how I built them are on my channel). Two solar arrays feed the inverters, and the third array goes to the Victron CC.
Do you know how this battery is performing now...Still no issues? Thanks!
The battery held up well, but the BMS wasn't up to the task. The BMS is the battery management system inside the case. It BMS in this battery was limiting the current to the motor too much. We swapped it out for a battery about the same size (Ah) but with a larger BMS. Check the video out here: kzread.info/dash/bejne/fKJ1lrRqqNipmLg.htmlsi=WWLVq5KBoaGev7PS
@@DavidPozEnergy Okay thanks. I just ordered the egf 48v from signature so hopefully it’s the newer version. I see It is rated at max 200ah output and states the BMS is rated at 200a.
@@ajsfree Cool, were you able to use my link when you ordered it?
@@DavidPozEnergy yes on the battery but the charger did not pop up. I should have it installed within the week. Thanks again!
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.
Thank you, I appreciate this.
how much can you sell it to me?
I loved the upgrade as well.
Hi Dave try a KPP. Build this thing , It's the way to go.
Is it possible to make this system work with only a smart phone no lap top and a weak internet hotspot???
I think so, but I can't say 100% because I used a laptop. First, Schneider knows that a lot of customers don't have internet, so this is how you get around it. 1. Find internet somewhere (coffee shop, library, etc.) 2. Download the firmware file to your device. (laptop, tablet, etc) 3. Go to the insight home location. 4. connect to the insight home's wifi signal 5. Open the insight home using an internet browsing software (ie. Crome) 6. Follow the rest of the steps in the video to find the firmware file on your device.
@DavidPozEnergy I did get it working but will picking a laptop ASAP.
@DavidPozEnergy thanks for responding. Maybe I could put together a list of question's and you could do a video about solving these infantile issues as they arise. There are so many settings... I'm not used to this level of functionality. All my other systems where plug and play. But I can't argue with its performance! It's outstanding charging my Tesla and running my farm with one inverter! I do still wish they would sell a hard wired control panel though...
As a licensed electrician, I am very intrigued that these little alternators are simple 3 phase motors. I had no idea, and now I will be experimenting with this myself. Also, I have to say; I am very impressed at your cleanliness with your wiring, proper gauges (even when you weren't sure on the output amperage, you anticipated well!) Followed!
Excellent work. I too live off-grid and I have a similar size engine sitting in my workshop for over 2 years, just waiting for me to do exactly this. So it was great to see how you made yours. I think the only change I would make is to have the engine and alternator mounted on the same plate to stop the engine vibration affecting the belt. You've inpired me to get to work on my build!!
I agree with you. Check out video part 2 and 3. In part 2, I welded a steel base for both the engine and alternator, which took care of vibrations. I also did some thermal imaging tests. In part 3, I fine-tuned fuel efficiency.
dont use a charger. use a DC-DC konverter for your Battery voltage. LIFEPO Batterymanagement does the rest
I have watched your series on Schneider so many times, I can say your words! lol. Anyway, I came back to this video to see how you turned it on because today is the day I am turning mine on. I hope I won't see smoke! Thanks for all you have done in documenting this so others can learn from it.
Thanks for watching. How did commissioning go?
You should not add drain holes. Modern Air Conditioners use the condensate water to cool the hot outer coil. The outer fan has a ring which is used to splash water on the condenser coil. If you make holes to drain water, this can no longer work properly.
3:15 BRASS = very bad!
Does the LifePower battery have fire suppression? Are the cells any different in the LL battery?
The newest version of the battery does have fire suppression built in. The newest version is here: signaturesolar.com/eg4-ll-s-48v-100ah-server-rack-battery/?ref=4_rHcgZ9x-TiF- Please use discount code DAVIDPOZ50OFF at checkout.
Honestly, Buy Victron…. Cry it once and be done with it. My Victron system has all of this and much much much more.
