Yeaaahhh I can’t believe how fast you are, you installed everything in less than 12 minutes!!! Electricians would be jealous!!
Nice watching you getting out and making some different fun projects helping people out!!
12 weeks more like it lol I want to do this stuff more and more - pitty it's a two hour round trip - there are so many more projects i can do out there. HWS is next
@@HBPowerwall Love your videos but you have way to much time in those batteries, Lipo from the Ford EV is the way to go, or similar battery, each of my batteries are 3.7 volts at 27ah and have 150 amp discharge rate. Only positive i see with those is the stuff they are making for the 18650 is getting better, like wall mounts and holders. With all that said, i still like playing with my free 18650 batteries lmao
If i had access and finances to buy EV batteries I would in a heartbeat - but this project fits with my wifes budget lol
@@HBPowerwall How much money per KWh are you spending when you build these 18650 packs? On ebay Salvaged Volt, Bolt and other similar batteries are selling for really really inexpensive compared to cell prices I've seen.
really love the setup. complete wiring diagram and list of parts would be awesome as well. Awesome job Pete!
Sure - that'll be next after the HWS video :)
Thanks for the step by step video. I'm actually aiming to update my SLA battery bank to a Lithium power wall similar to this. Yours looks very neat with the custom wire length and breakers. Mine is a 48v array and I harvest 53v at 16amps at 1.31killowatts. Small but it powers plenty. I just need a bigger storage medium. I really need to buy a Batrium monitoring system to gauge what's going through
I much pleasure to see clean work and use pure technical electro parts.wow
I really love your channel. I am looking forward to all future videos. Especially when you process your cells from laptop batteries to your power wall I would like to see the the step by step process from shucking (though I have seen your shucking videos already) the cells, to testing to building the pack. I would also love to see how you build the power wall brackets. Anyway Thank you for your hard work ... or is it work, maybe you just play around with stuff all day and call it work :-) Thanks again!
Great looking setup!!! Don’t feel bad about the Batrium, I know everyone who does anything electronic has seen the magic white smoke more times than they will omit to. Thanks again for all your help,time, and information. The video on the new Batrium BMS you did is better than most commercials on TV.
Magic white smoke needs to be released it's a right of passage lol
*Pphhhfffftttt!*
Yes, I’ve seen it a few times.
You and Jehu are always my goto for this kind of stuff. Your content is top notch!!
Thank-You bud
hats off to you for sharing your mess up. been there, done that. thought I was connecting two 6v batteries in series and was actually shorting out the whole battery bank and melted the terminals off them! surprisingly easy to fix with a stud drilled into the post but it happens.
Yep mistakes are part of my learning. Sucks but it happens
If you’re accepting small criticisms, I would tie down those blue and red cables from the battery banks near the enclosure. If something heavy falls down and catches those cables, there’s a chance they’ll pull out of the screw clamps and make turn the inside of the shed into a pretty sparkler. (Never trust horizontal cable runs).
will do!! Doing it better is key! also have to install the shunt trip in that position so that'll take some horizontal real estate out of the equation
Looking good. I cant wait until Im up and running. Thanks for sharing
How far off are you?
@@HBPowerwall 1/3 almost. Check my vid. I posted it yesterday😁
Checked out/ subed/ & commented :)
@@HBPowerwall Thanks brother.
Amazing install mate. Thumbs up from the uk.
Thanks Pete
Nice job Pete. He will be much happier with the lithium!
For sure!
I really love this video. I have AGM batteries and wish so much I could have the 18650s here in Chile but it is a hard thing to find. So it is too bad you do not sell them! Jim in Chile.
International shipping would be killer and kinda goes agains the whole recycling/environmental thing we are doing with them.
Great job Pete - so satisfying to see one of your babies doing good...
Seriously chunky cables there!
(I think I would have left them a little long with a loop instead of cutting exactly to length, in case the boxes need rearranging later!)
I wanted to do this one as 'right' as possible - sparkie should be out in a few days to do all the final connections and move the breaker panel from the house to the battery shed.
@@HBPowerwall Look forward to seeing final results, just don't forget to do an update video!
Will do for sure!
Great i like what youve done
Helping out other people super good keep the good work up
It's been enjoyable!
Good Job mate !!! 👏👏👏
Thank-You Bud
Great video mate.
Thanks Bud
Very nice setup for off grid :)
Works very well so far but only in service 3 months (it took a while to edit lol)
Great video, do you have any photos/schematics of your parallel group design? Is each cell individually fused to the busbars on the positive end? I'm trying to find a sturdy safe design for 160p groups. These looks nice.
This video explains these ones i made - th-cam.com/video/QmFlyFwP8nY/w-d-xo.html
Amazed at how flexible those large gauge cables are. I don't think I have stuff that flexible here in the 'States.
I use fine strand welding cable. Its flexible by design, can carry 300amps continuous & is only $10/m here in australia so it's affordable & easily accessible. Would be nice if it was red and black tho
Nice....Very well done! Don't feel bad about the mishap, if makes you feel any better I burnt up a brand new K-Weld. The sad part I had the case for it sitting right there in front of me, got lazy and in a hurry the next thing I knew, ZAP.
It happens :( But moving on if I get another 100k more views on this video I'll be able to replace it lol
Nice work, impressive
Thanks John
That would hurt when you blew up the longmons and watchmon. I guess we can learn from that is to not get too comfortable and triple check our work. 10kw is a lot to have lying around. You must have built quite a number of packs.
You do make is look easy, the way you make all the cabling. I quess the right tool for the right job make a difference.
Good job again Pete.
there are countless hours of redoos in this video.. really wanted it done well.. now i want to redo it all over again after the hotwater went in lol
this dude can wire my house anytime if I ever covert to solar
I'll blow stuff up for ya lol
Don't worry about it Pete, sparky happens 😜
I think we've all done that "doh!" moment when we plug it in incorrectly. Live and learn, buddy, live and learn.
i don't like doh moments that end up like that ....
@@HBPowerwall Yeah, nor do I. Especially the expensive kind. But it's very nice and humble of you to have posted this mistake and your feelings on the matter for others to learn 😎😉
Awesome job.....👍😎🖖
Thank-You Sir
nice job!
Remembering that time you shared that meme:
"People are shocked to learn im not a very good electrician"
But im certain this wont be an issue haha
I didn't do any 'electrician' stuffs lol refuse to touch 240v I don't want to die!
@@HBPowerwall Ah! So THAT'S why such low volts! Too many cells in parallel for a config with second hand cells, even with individual fused lines. Jehu Garcia seems to have a much better method of building power walls. And by the way you die MUCH more easily with DC than AC - the current never gets interrupted on DC shocks. That's probably another reason to use 48 volts though right? 192 volts DC is more my idea of getting power from multiple batteries - just like my pro Riello 6kVA UPS! I can run universal power tools or any universal motor directly off that with no conversion and ampage losses.
@@boblewis5558 Jehu's is fantasitc for small jobs, but sucks for scale - seen many more issues with his packs than are public. BUT they are VERY good for small packs don't get me wrong - my next battery is bigger again and I will be adding another 1200 cells soon to this battery. It's been in service for almost a year now and is still super strong with out any signs of issues. Going to pull it out of service and retest each pack and see how it's holding up properly.
Merci pour cet exposé théorique, beaucoup de personnes ont les mêmes réflexions avec le même genre de matériel, mon avis est que le réchauffeur me semble compliqué à mettre en oeuvre, dans ton exemple il ne dispose que de très peu de volume d'eau et pas de circulation donc quand la résistance va être alimenté je pense que l'installation va très vite se trouver en surpression, je pense que la solution la plus évidente serait de la mettre dans le ballon, chez moi avec un 300l quand il est à température de moyenne c'est 2.7 kwh par jour à gagner donc pas tant que ça pour une installation de 3kwc qui peut produire 15kwh en été.
Outstanding!!
Thank-You Sir!
lately i been wanting to learn how do do this and been wanting to build
something. im JUST starting. helped clean a hoarders house which had 2
kobalt 80V lawn mower batteries which never saw use and degraded just
sitting in that rate hole. of the 40 cells i got 20 in good "physical"
condition.
before i even bother testing charger discharging ( and
buying all the relevant equipment) i need to start stocking up to make
it worth my time. any suggestions for where i can acquire sources? this
weekend im going to ask around at local Lowes/Home depots and see if
they are willing to allow me to give some of these battery packs a
second life.
Hey Pete. Thanks. I really appreciate your videos. I have a question or a request even. Could you elaborate, why you use a charge controller, when your inverter can charge your batteries as well (maybe you can go over that in a video???)? I have my first 7 packs ready and want to go ahead with ordering an inverter but I want to understand why you use a charge controller instead of the inverter to charge your packs. Thanks!!!
I use the MPP Solar PCM60X charger controllers cause they work! That's not an affiliated linked or sponsored comment it's the fact they really do work and stood the test of time. Its Heat... in summer it gets a touch hot over her in Aussie land so keeping head separate to the inverters is a great idea when an air-con gets left on for days and days at a time along with the normal house loads and cooking. THAT said it would be more efficient to use the internal charge controler as it's much more efficient as the PIP inverters will use solar power first so there is less energy 'inverted' so to speak. NOW this setup it's because of the limmited size of the PWM charger controller in the PIP2424HS & those fans are a touch too small for that unit.
@@HBPowerwall thanks for your response. So if I understand you correctly it is not necessary just recommended because of environmental conditions in Australia. I will try without and should I experience issues with heat I can integrate a separate charger. Thanks again for your feedback. Greetings from Canada.
It's an all round versatile unit that I trust so much of the rubbish others push (and my self in the past) isn't tested properly and just there for aff clicks don't care what happens in six weeks time.. It's time to change that train of though and do better where possible
Nice work man! It sucks right at the end you blow it up!
Sure did lol But it has changed my mates life with how well it works
@@HBPowerwall Cool man! aways nice when it works out at the end!
I'm curious. Why the PCM60x as opposed to using the charge controller built into the PIP? Capacity maybe?
Heat is a big reason but that inverter is 4 yr old and only have pwm controller and 30 amps max at 60v or something. So not efficient
Very good point, mine has that even the capacity is measured, but it's a programmable mppt, only thing i like is the read out he has on the laptop.
My newer pips have the same ability as the PCM60X but still prefer to keep them separate
Yes, a PWM charger is much less desirable. Mine has a built-MPPT charge controller. One advantage to using a built-in charger is efficiency. Solar can be converted directly to A/C within the PIP on demand (when solar is available). Sorry about your Watchmon, by the way.
Very informative and helpful,, great video!
By the way, it means that you are still human..... Big deal, ppl make mistakes lol,,, God bless you and your family!
I appreciate that!
great to see you help a friend. why a you afraid of the ac power lol
Its not legal to diy 220v in Australia
Could you explain the relationship between the solar charge inverter thinking it is charging a lead chemisty and how the batrium deals with that? Does the batrium know to feed dummy voltage data back to the charge controller to get it to back off etc?
charger controller is set to 4v per cell - so 0.2v under it's max safe voltage also CCCV is turned off. Has worked for me for 4 years so far. Batrium doesn't control the inverter at all. But does take care of balance and hws, & soon the shut trip will be fitted to stop all charging & discharging if there is a high/low or hot/cold issue with the batteries. There are 18-20 temp sensors in this setup.
@@HBPowerwall thanks for the detailed response!
Damn Good Video Man!!! BOOOOOOOM💥💥💥💥🤘
THANKS JOE!
AveRage Joe soooo much POWEEEEEEEERRR ohhh yeaahh
the humble feeling you may had after the break. if i srew something up and curs, i let it all out and after that i am humble again and start over and laugh about myself.. "stupid me".
:)
Took me two weeks to go back after that mistake i was so embarrassed and angry at my self. Poor guy needed to use the generator for two weeks cause i didn't want it running without bms
@@HBPowerwall i am feeling you - may bring him some beer? keep up the good work mate!
Did you have to change the floating voltage on the inverter for this?
I'm not using the inverter charger (yet - but you set the bulk & float to the top charge voltage - Currently it's 28v and working well still. Heading out this weekend to finish an upgrade and pull those batteries to test them after 12 month of service
Well done! (not the toasting part though)
Did your own bms survive.
Blew the ass out of the bms unfortuntally...
Hello HBPowerwall. This is first video, where i noticed that you are using metal plates instead of fuses on the cells. Why? How about fuses? Thank you.
Faster as trying to build the battery much faster, working well almost 12 months later
So sorry about the BMS
Don’t me sorry lol all my fault. As long as I don’t do it twice I’m good.
Can a 12v 100w solar panel charge a 24volt battery? What fuse can i use, and if i only use it for a 35 watt gadget, can i use it 24/7 without unplugging it. Please simplify. Thanks
what is the name of the tip you crimp on the fine wires
The are Bootlaces or ferrules ebay.to/2GJRtNI
Great video! Really sucks about the Batrium though :(
I agree but never minds - what is done is done..
so beautiful.!!!
I agree
The thing about these small cells in a large pack is if one cell goes bad how do you find it or replace it. I am thinking it is much easier to build packs using larger cells that are now available. Building packs with hundreds of 18650 cells seems tedious and unnecessary this day and age.
Don't forget i started this process 4 years ago. 18650 cells scale perfectly from 4 cells to 40,000 cells. Anyone from any economic group can build this to suit their needs from a led light to do home work in a remote town in Africa to a whole house setup because I can in Brisbane Australia. New large scale cells come with a high price tag that limmits their ROI.. My time is spent well building these. DIY is diy for a reason.
hi! my understanding is, there is an upside of using a zillion small cells in parallel instead of larger, more expensive units. when a few of these smaller capacity cells get weaker you wouldn need to find and replace them immediately coz overall you'll lose a fraction of an amp with a few weakened cells in a pack of hundreds of them. with time when your pack's cell death rate hits double digit percentage or overall capacity becomes too low only then you may need to rebuild.
5:25 Pardon the dumb question, but why do you have a breaker on both the positive and negative? (I know this video is old)
Apparently thats what you're meant to have... so I just run with it
heya that is a very good upgrade to bad you blow the batrium
Update - new batrium still running
Very Good
Thank-You

Can I ask why did you used 2 single mcb's and not a double pole mcb
Because that's all I had, upgrades will come with time.
So I’m New to this and am learning little by little but those little batteries can store up to 10kws which is 10,000 watts right?
watts has nothing to do with kw - watts usage, kw is storage..
Yes but 1,000 watts is 1 kw is it not? So if I’m doing math calculating how many watts i use in my home that will define how many solar panels i need right or wrong?
Why you use PCM60X and 24v MPPSolar (this one also has a built-in charger??) ?
It does, but was very low input from memory, PCM60X is an outstanding unit and that PIP2424HS over heated with just a 2000w load for 10 min, ad an SCC to the mix and it renders the inverter useless. NOW that i never used the internal charger that inverter is still running today.. Must be something to my thinking
@@HBPowerwall is this model better for all in one? www.ebay.com/itm/GK-3000w-24v-Solar-inverter-230v-80A-mppt-solar-charger-PV-input-500vdc/163718879615?epid=20032787170&hash=item261e67d97f:g:bckAAOSwNWdc9dUd

@@HBPowerwall For start I would only have 3 solar panels (store.bisol.com/premium-mono-305-wp-187.html)
Open voltage for one panel is 41v (41V x 3 panels serial = 123V only ???).
MPPT range is 120-450V. Is this enough just for very sunny days or even shady ones
Question, how come i didn't see any BMS in that system? Am a little new to this.
Umm there is a www.batrium.com bms... i even blew one up in the process of installing it
@@HBPowerwall ok Thanks.
Hey from the video u said u installed 14 250watt panels on the pcm60x thats 3500watts of solar. From the pcm60x manual its 3000watt charge controller... how does it deal with the extra wattage.... also from the manual it says its a 60amp charger so if you are charging a 24v battery you would only get alittle over 1500watts charging capacity from the pcm60x therefore you are never going to get the full 3500watts from the solar panels you are only getting half. Am i correct in assuming this is so? And if so why did you set up the system this way? Could have split up the panels between the pcm60x and the pip and you would get closer to the 3000watts charging power....
We have since moved some solar over to the pip inverter but all the panels lay flat on the roof and there is massive shading during winter
What was the max the pcm60x was giving you when you had the 3500watts connected? I am looking to do almost the same setup and was wondering if the pip and the pcm60x could handle 1620watts each... on a 24v setup
you might put drip loops next time, might save the day in a bad rainy day and a leaking roof ?
The change of getting water in that area would be so slim, but couldn't hurt for sure.
So cool
Was enjoyable & thanks for tunning in .
sweet setup . fried batrium loss come out of your pocket?
It did, It hurt ... three times - blowing it up, telling the wife - then paying for new one :(
@@HBPowerwall oh sh!t !!
Are you looking for Panasonic’s 18650’s ?
Always looking for cells
8:03 What is the purpose of the shunt and how is it being monitored if the input to the shunt only goes from the solar controller straight to the inverter and nowhere else? Isn't the purpose of the shunt to be able to measure battery charging current? This means you'd need to measure the voltage across the shunt itself, right? Is there a wire I can't see or am I missing something?
The shunt is for the Batrium BMS, takes care of all the SOC of the battery between solar, battery, inverter .
@@HBPowerwall
Yes but it can't physically do that unless there are wires on each side of the shunt going to the BMS. Where are they, especially the wires on the left side of the shunt. I can only see the thick wires going from solar to inverter. There is no wire going to BMS.
they are connected I assure you :) useless if they weren't - support.batrium.com/article/207-video-shuntmon-installation-hardware-and-software

Batruim bms has a problem in the connection wiring. They need to improve to make it more simple and safe.
I hope you contact with batrium team to solve wiring issues
I wired it wrong no issue on their part.
@@HBPowerwall
well yes, you wired it wrong.
however batrium probably mostly sells to the DIY market. so it would certainly be an improvement to make the connections fool proof. also the colour coding markers cannot be seen from all angles.
average joe destroyed his batrium control board, now you. and i am sure there are many others.
I guess if their product was in the millions of units not the 100s it would be cost-effective - but I can buy directional tires put them on the wrong side and it's not going to change how they make the tyres.
@@HBPowerwall
when average joe wrongly connected the data cables and the batrium control board blew,
they changed something so it would not do that anymore.
if it is designed from ground up to not self destruct, i don't think it would cost them all that much.
it is very easy to wrongly connect. it just happened to you, it happened to average joe and you guys are by far not the least knowledgeable guys.

There would be less resistance if you used solid silver 00 gauge wire in place of that copper 00 gauge wire.

Yep... want the last thing to turn off to be the thing that could tell me every bit of information about a failure as possible batrium works from 5v to 60v so even weeks after battery has failed i can still get logs
