@@invictusfarmer7188 Engineering Explained. it's 10 seconds into the video
@@yellowood252 i seriously 100% missed it. thank you for fixing my ignorance lol
@@invictusfarmer7188 lol no worries
Jehu, I’m an engineer, I agree with your assessment however I did have one of my early battery packs I built flame up at 2am and almost burned down my storage /workshop . I even burned my foot putting the fire out . Lucky for me the pops of the exploding cells woke me up and I caught it early. I tried replacing a bad cell group with new cell and that was a bad idea.
I now pot all my battery packs with a good layer of GE Silicone II at the top and bottom to prevent thermal run away.
I have not had a problem since and the packs even last longer. I should have bought more silicone before the price doubled.
Justin a Grin Technologies is also experimenting with potting cells in resin completely eliminating the chance of a fire.
Locally in Chula Vista we had a Chevy Volt catch fire at 12 midnight, caught the Tesla next to it on fire and blew the garage door 50 feet onto the street. The kids room was above the garage but they were ok just shaken . They fire department got there quick and saved the house.
Maybe it’s a better idea having a truck parked in the driveway powering the house than a power wall in the garage. I would sleep better. I have a solar system and currently using golf cart lead acid batteries but I will be building a separate powershed separate from the house using lithium batteries..
be very careful building these packs . They don’t give you a second chance!!!
Keep up the good work!
Is lead acid safer than lithium?
@@uhjyuff2095 oh yes and the 6v Trojan batteries are the best for solar. I have 12 of them running 24 v because the panels output 24v.
Connected to a 24v to 110v sine wave inverter 5k watt for the house.
Lithium does hold a lot more energy and I will be building a separate power station not attached to the house to increase my power to 10k total watts.
I do love building these lithium packs. You just have to be very methodical and meticulous working on them.
I have a nice scar on my foot to remind me!!
I've always wonder if you have to pay extra insurance on your house or not with a powerwall. I know in energy storage they have serious fire suppression that you are not going to be putting in your house.
boy oh boy a Volt catching a Tesla on fire, the two worst cars known for randomly exploding
you put off a fire with your foot? wow!
Last I checked, you have to buy the upgraded version of the F150 to get the ability to use the battery as backup for your house. It's more like $90k.
@David McKee but you'd be betting that you won't need your warranty on this brand new type of truck from ford lmao
Plus cost to modify your home setup to accept charging.
Believe that is true, need to have Extended Battery for V2H. And the Ford EVSE.
Thanks for the video Jehu.
I do love engineering explained channel, because he knows his math, and always got to the bottom of things.
While watching his take on this problem, I told myself. "Ok the powerwall doesn't make economical sense, but I'm pretty sure, if you slap those jehu's battery pack together, you'll be way better off financially".
At the time I didn't realized that those tesla powerwall were 500$/kWh.
Thanks for the video as always!
Last power outage happened on Thanksgiving. I hooked up my 120v ryobi generator to my manual transfer switch on the main breaker and to my surprise the oven worked and I was able to keep using it. The oven was and fridge was on running off a little 1800watt inverter generator!
Having some sort of backup power in an off grid house is necessary but for on grid installations where excess power can either be used to backfeed the grid or charge a battery, truck or otherwise. A grid backup consisting of distributed batteries in evs or powerwalls could create a more reliable grid and possibly do away with peaker plants.
Dude, I’m SUPER ready for a simply explained video that will teach me how to build a wall. Lots of technical rambling’s that Joe average don’t understand. I’m trying to support your channel but you’ve gotta help me help.
You have to teach yourself about Volts*Amps=Watts and then understand the terminology like capacity=energy over a period of time=Amp Hours=Watt Hours and power=instant amount of energy=amps=watts.
Ohm's law would be the other thing I would recommend understanding as well since resistance is important and its a fairly simple concept.
Then understand the voltage ranges of common chemistries like NCM 3.6V/3.7V and LiFePO4 3.2V/3.3V. Then understand series and parallel in battery building and how 7S NCM is "24V" and 8S LFP is "24V" while 15S LFP is technically 48V nominal exactly the industry uses 16S 51.2V nominal for "48V". NCM "48V" can be 12S to 14S but that voltage range is quite wide with 12S barely being 48V at its full charge voltage (50.4V is max voltage at 4.2V per cell.....but its commonly used as 48V in the e-bike world. 13S is also used in the PEV industry for 48V but 14S is what most energy storage systems (ESS) consider "48V" despite having a max charge voltage of 58.8V)
Learn these basic concepts about electricity and how lithium packs are built (just the basic series for voltage and parallel to increase capacity and power output) and you can follow along to ANY of his videos.
Inverter jargon will follow along with all of this and solar charging isn't too far off....that involves being able to understand the terms on the back of a panel and how to series your panels up for the max voltage your MPPT can handle typically. PWM is a waste of money so don't even bother with it.
Wouldn't hurt to look at things like DC to DC converters (not DC to AC inverters) so you understand buck, boost and buck boost aka step down, step up and step down/step up voltage converters. Buck converters are usually most efficient (there are several common ways to build these DC to DC converters and efficiency varies) in the 90% to 95% range. Boost converters can be in the low 90% area when the voltage difference isn't extreme but when you are boosting 12V to 72V you might only get 78% efficiency at best. Buck boost converters are typically the least efficient as they allow you to go either direction but often end up in the mid to high 80% range under ideal conditions...sometimes they can be in the low 70's if you have large voltage differences.
Most of these Scooter and bike batteries are some flavor of NMC lithium battery chemistry. They are great for portable devices and portable power but the more of them you get together in one place the greater the chances of having a fault that causes a cell runaway condition. If a person uses these in their home solar installation they will likely need a separate conditioned shed to locate all the batteries in case one ever goes up in flames since they tend to get hot enough to spread to everything around them. A person may be able to get away with doing an inside build if they can build all the batteries into a heavy duty metal enclosure that separates a large pack into several smaller packs to reduce the number of packs that could be involved if one fails catastrophically. I don't even trust this chemistry in a vehicle since the chance of failure and thermal runaway is always looming overhead. Chemistries like LiFePO4 and LTO are far safer alternatives for home power wall storage.
There’s so much wrong with what you posted. I’ll make a video addressing your concerns.
When I first made 2 lunch box sized batteries from scooter battery cells For my electric lawnmower put them in fire proof bags and only charged them to 4v per cell. They weekly got beat up being on top of the lawnmower for a couple years. Never had a problem.
Now I have 5kwh of scooter batteries for a diy home backup. I charge them to 4.2v per cell and have them in an aluminum fire resistant box.
I now really feel these cells are safe if you are below 1/2 their C rating, never over charge them, don’t let them be physically damaged and have a decent case around them they are perfectly safe. But I also don’t think I would trust the small $10 bms that is on them. I want a voltage readout on every bank of cells so I can verify they never go over 4.2v.
The Ford Lightning seems like a pretty nice deal, also its a plus that Ford is not stringent with repairs and replacement parts, I can see myself owning and keeping one for a long stretch of time.
I used a 6-circuit manual transfer switch (designed for generators) to run an off-grid 48v LV6048 inverter with my 290AH 48V 18650 powerwall. Works great! 6 x 380watt panels keeps power running throughout the day and charges my battery which takes over at night. The transfer switch has several advantages to it.
Awesome
I think this is an excellent idea! Now all you need to figure out is how to charge them with the help of magnets so you can have free power.
That truck is 2× the price with the battery backup,,you said 40k it's about 80k
Victron and a few other companies make a split phase inverter, or you can hook 2 together (upto 6) and program them for split phase or more power. Around $2k for 5kv split phase. Also built in battery charger, and power boost (3kw gen+ 3kw inverter=6kw useable)
I really appreciate the "it does everything, so it can't do anything" comment. I have run into that same thing many times.
Good points on both sides of the argument. Other factors on either side. Must pay for monthly car insurance on truck. The truck has a resell option. The powerwall has software to do smart rate charging. If you need a new car anyways this may be the biggest factor. The truck may catch you house on fire if it anything like the chevy bolt, so far the GM track record not good, roll the dice at your own risk. The cost to integrate the power into your house is a cost factor: Grid tie vs. Fuse box mods vs. standalone options.
A lot of great points in your video. I was intrigued by this idea with the Ford Pickup but as you said, it's still not yet available and may not go for the 41K price when and if its available. BTW, most Electric Clothes Dryers are 220-240 volts and they out number Gas Dryers about 3 to 1 in the US. Also Electric ranges are usually 220-240 volt and edge out Gas ranges about 60% compared to 40% for Gas on average across the USA. Keep in mind, older areas will be be more Gas orient while newer areas will be more geared to electric. However, IMHO when given the choice, the best way to go has always been to go for natural gas in your ranges and dryers, since running at 110-120 volts is easier to manage. Also, in a full on black out your gas range top burners will still work to cook and provide some heat.
I watched that video earlier and came to the same conclusion. I have a ton of scooter packs and run my house off them, but what I would like is a 10s PCB so I can configure all my loose batteries and make everything 10S
thats easy
@@jehugarcia make a module that we can expand onto over and over with like a buss bar or something
Click in a ton of 18650s every now and then a kw at a time
I already have that czcams.com/play/PL2l32K1w0jp8s0_Ac5GkuA0PCGzdNuLWD.html
This idea would be great for powering the house at night....like window ac s,fridge,do laundry at night.(provided you still have enough juice to get you back and forth to work next day).Only thing is you'd need to have home solar charging and 2 ev batteries to swap one for the other alternate days.I recently read that solar batteries are $400-$850 per kwh whereas EV batts are down to $120-$140 per kwh so math tells me that even having 2 EV batts still cheaper than one solar battery. And if their throughputs(lifetime kwh production)are proportionate to battery capacity then it's a definite WIN.
Good videos Gentry solar makes a 6kw inverter that can be set up for 12-24-36-48-60 volt based in Michigan 👍🇺🇸😎
Thanks I’ll looks them up
One think most insurance will not cover in case of fire or fault if you use a diy power wall or a vehicle with vehicle to load functions. On the other hand the power wall is insurance.
I think it depends where you live. In Europe the first cases of arrested people because of the insurance companies deny covering the fire incidents , all costs are charged to the person who made the "powerwall" and then charged with other crimes.
YOU MY FREAKIN HERO, G! THIS IS DANK AF, MY DUDE! SERIOUSLY MAN THANK YOU, YOURE AN INSPIRATION!
I didn't know that in the USA there is a such problem with electricity, and you need to have your own backup power station, I thought everything is cheap and available there. In my country, Ukraine, there is a war going on and the most of power facilities are destroyed by missiles. This Powerwall system can be not only as backup but live(real) lifesaver!
Autonomous driving vehicle not just a battery! Love your channel…
I use my two 72v Cushman Hauler Pros for my emergency solar backup. I open my main breaker, power up my 15kw inverter, sync my 35kw grid tied solar inverters and regulate their output to carry my AC loads and maintain full charge on my batteries. No frequency shifting, rather continuously varying the solar inverters outputs to carry my AC loads and maintain battery SOC. I can run 2 houses, office and welding shop. Works great but I may average 1 or 2 utility outages per year so dual purpose battery usage is the only way that makes sense.
How do you sync your grid tied solar inverters and regulate their output? I have Tesla solar on my house with the grid tied inverter they installed with it, and I'm wondering how I can implement a DIY powerwall but somehow connect it to my solar energy coming from my roof and through the grid tie inverter...
@@sourcecreator2222 How technical are you? Simply put, you separate frome the grid, use a DC to AC inverter to generate 60hz to trick your grid tied solar inverter to start production. Most people use frequency shifting of their inverter to trip the solar inverter offline when the batteries reach full state of charge. Then when the battery charge drops the frequency is set back to 60hz and the solar comes back on. What I'm doing is dynamically and proportionally regulating my solar inverters using Modbus communications to control the inverters export limit. This way my batteries simply act as an accumulator to supply or absorb sudden changes in my home and shop loads. As I turn something on, the battery voltage drops, I proportionally increase the export limit and my solar output increases to supply the load, and the reverse. If the solar can't meet the load, the batteries carry it. No hard on and off. Much better system but more complicated and not yet adopted by inverter manufacturers. I really don't know why.
@@andyfeimsternfei8408 Wow, it sounds like you know what you're doing! I'm just an electrical engineering college senior dropout who really likes to DIY and aspire to create my own powerwall and connect it to my professionally installed solar system + inverter. I don't have too much technical background outside of my continual ventures in my DIY projects, which so far have been building an ebike (with a purchased electrical kit) and converting my central AC air handler from using an ECM (electronically communicated motor) X13 motor (which failed) to a PSC (permanent split capacitor) motor. Basic stuff but my next project is this powerwall since I can really save thousands of dollars and learn a TON if I do it myself. That's why I'm looking into inverters and asking you about how you hooked up and operate your system with grid-tie equipment. Thanks for your reply.
@@andyfeimsternfei8408 what's your background that led to your expertise in power systems?
@@sourcecreator2222 43 years in power plant design/build electrical, mechanical and civil. Mostly dams, solar, landfill gas...
It's minimum $20,000 more than the base model to upgrade to the larger battery, which is required to do the home power thing. So, roughly $60,000 minimum to have the lowest-specced truck with which you could do so.
AFAIK, waiting to order mine, is that it just comes for free with the bigger battery, but the smaller truck should be able to work with it too.
@@SnowIsMyTerrain They just announced this capability for the lower capacity battery like a day or two ago. Before that every bit of information which came from Ford up until that point had indicated that the larger battery was the only one which would work with V2H. Now they're backtracking because people like myself were pointing out the ridiculousness of the situation.
I just got my scooter batteries from JG35. Ponied up for the already awake ones just to be safe. Great deal for me and I already have the design to put them in series and parallel, yet charge them individually. There are so many great batteries available for reasonable prices.
As a ford technician, I can tell you for certain, new vehicles are lots problems, and expensive. I wouldn't buy for at least two years. They WILL have engineered, expensive problems. You can bet your bottom dollars on that.
Great vid, one point of correction - ford's automotive gross margin is around 7%. If they sell the f150 for 40k it's costing around 37k to build. Not 100% markup :)
I have a slightly different perspective, but it is based on my state incentives.
First of all, MA allows you to get a 0% APR loan on the power wall for ten years. You DO need to get the loan for whatever the power wall portion of your installation is privately, but theres a list of nearly 100 lenders that work with Tesla and MassSave to get it done.
After that, your utility will pay you to use the juice in your power wall during peak times to the tune of $1000 a year. They say peak times run between June and September and they will call for power no more than 60 times during that time period. The $18,000 0% ten year loan I took out for the 2 power walls I am having installed will be more than half paid off by the utility over the ten years I have the loan.
I know. Not everyone lives in MA. In fact, most people reading this do not. My POINT? We need to stop making blanket statements about what makes the best financial sense, and instead encourage people to do some basic research on what incentives and programs are available to them. You may have nothing close to what I mentioned or you may have something even better. The F150, as well as the option outlined here, is a worse option for me, in the long run (unless I am able to do my own work, which I decidedly am not).
I am a big fan of DIY. I think a lot of things are easier to do than people realize. My concern with something like a diy scooter battery home backup system is liability. I suspect, but can't say for sure, that a fire caused by a home made job is going to be looked at by your insurance company a bit strangely. At the very least, I would confirm that it is not a problem before proceeding. Last thing you want is your house to burn down and the insurance company to refuse coverage claiming it wasn't professionally done. That is not even mentioning risk of life involved.
Did you forget that the powerwalls has more incentives? And let’s not forget that in order to get the full battery from Ford, you have to get the more expensive trim at over 80k with dealer surges (maybe more) soooooo idk where you get your calculations from. A tesla power-wall can cost less than 10k maybe even 8k with credits (depending on where you live
Powerwall isn't the best use of your money. Even with incentives there are many better cost efficient options
i made an eskate and all i could find was a scooter battery, so thats what i used and it worked fine and at a great price
I just found your channel. Good job. Here is an idea for a video. For those of us who already installed a commercial battery (i.e., Tesla, Enphase), how to interconnect another DIY battery to increase capacity.
I need to get going on a small system for my outdoor shed, that should teach me the basics and not be very expensive. From my initial research, Long Island NY isn't very great for solar but maybe good enough?
This is a fantastic go to channel. You the man!
I love the Power to PR shirt!
Does the $41k include the installation of all the necessary materials and labor to hookup the truck to power the house? If so, it should include an automatic disconnect from the grid so as not to electrocute power line workers.
It doesn't. There's a whole gateway/inverter system from Ford.
One must use the Ford/ recommended ;charger' and the only time you can use the battery in the truck during a power outage! I read Ford info, and unless it changed, the battery can't simply be used as a power wall at any time.
the battery buy link goes to not found page..
It’ll be even more ironic once you end up with lightning power modules doing what you do with them.
Save the 20k on the truck by just getting the battery 😅
Nah you dont take it personally, you just dissed him for ignoring you lol
Very good response, I totally agree, except that I never had a doubt that Ford would deliver their promised prices. With Elon, on the other hand, I personally was skeptical of and think he's very often all talk. Freakin' walking a guy out in a suit and promising a robot in 2023, give me a break. But anyway.. I want a dedicated home power system, and don't want to put more wear on the EV battery. The DIY home system will be more sustainable and cheaper to maintain.
the 40k ford truck is a basic "work truck" there for its featureless. and it also has a smaller battery.
A powerwall can keep your grid tied solar producing electricity. A truck or a bare battery can’t.
Yeah, I would think that when the truck is connected to the house during the day time, the solar inverter could share the load to the house so the truck doesn't run its battery down... at least!
It’s easy to create a micro grid using most off grid inverters, your grid tie inverters will then turn on.
My understanding is if my solar is outputting 10kw and there is no where for that energy to go it will damage the micro inverters.
So if I just connect my 240v inverter yes my solar will turn back on but won’t have anyway of controlling the power output from the micro-inverters.
Is that not true?
But the more important question is, if you don’t have somewhere to put the energy why would you want the system on then? If you have a battery at less than 100% SOC it can take the energy from your solar panels.
So my electric car being unplugged is my worry. I set everything up house is pulling 1000w plus I’m charging my car at 6000w so I have about 7000w of solar turned on. Someone bumps the charge cable or something else happens and the electric car gets disconnected. Bammm all of my micro inverters are destroyed. That is more than a couple thousand dollars to fix.
If I had something like a power wall. The power wall would absorb that 6000w until it couldn’t then it would inform the micro inverters to back off and produce less electricity.
I got a diesel truck, a diesel generator and a diy power wall
I love 48v. I built my own DIY solar generator and made a yt video of it.
build a medium sized power wall for 100 per kwhr, and buy the truck if thats your thing, but people dont want to learn or work all the time, they want plug and play.
If you go down the scooter battery route to create a larger home battery - of the order of 10-20 kwh - you are faced with a fair bit of construction/assembly. Part of the attraction of dual-using an EV as storage is not only the assumption that you already own it (as transport) but that it is already assembled. A used Nissan Leaf is probably a better example for this.
I couldn't own an EV unless I purposely chose to charge up at some supercharger ~once a week because I live in a condo/townhouse, no garage (parking lot parking), and the roof is not mine (I have an upstairs neighbor and the exterior is owned by the HOA). EVs aren't going to be for everyone.
Usually when something does many things, they usually do nothing great!
I agree with you, except the iPhone is such an amazing camera that it has no time for being a phone
It will be very curious to see how the "diy" "powerwall" subject goes in the future, here, due to insurance companies rejecting coverage due to the presence of non certified devices such as diy powerwall or even store batteries, has already lead to some crime charges and some arrests because people just could not pay all the costs that the insurance company charged them with. Australia is ahead I think, they now have specific laws for the placement of a certain quantity of these batteries, so its not even legal to have them near houses, and also require inspection and certification even at the "legal required" distance from all house.
People's internet are still over copper, Australia is always behind the curve
@@AfifAhmad no not true, I have FTTP. There are times where we are ahead of the curve, we just have good, safe regulation.
@@Rubibi-saltwaterjim the US is rolling out 5Gb internet, meanwhile most Aussies can't get above 100Mb
Just imagine the insurance policy you'd need for a 98kwh diy lithium batterey, recurring cost. Just get the truck.
That's why I buy from jehu:) just bought another battery love this for my diy project! Thanks jehu, I can afford!
Hey Juhu, I'm pretty sure my wife has been working on this save money by spending more for a long time😂, cheers.
Reliable inverters are good,,I use them. If you contact the company they will build you a 36volt..they just adjust a 48v or 24v to 36v
I built my own 15kwh 18650 powerwall for about $70/kwh
do you save the backup energy for a blackout? And if so, what SOC level is your battery stored at?
@@uhjyuff2095 I use the battery nightly to power 6-circuits of my house (1 to 2Kwh) during peak hours. I charge it to 55v and discharge to 50v. That amount of charge has been enough to run my house for about 6 hours, which covers our peak electricity schedule (4 to 9 pm). It should also help the battery pack last longer because i'm not fully charging or discharging.
Jehu I've seen a lot of videos about going solar but I haven't found one with lithium or other newer technology batteries with a 2000 watt pure sine wave inverter for under 1000 dollars that I can buy anywhere in Canada for that price including shipping I did find one that does fit those specs unfortunately to keep the price down they use sealed lead acid battery fortunately I had watched rv utube videos on proper care and maintenance of sealed lead acid batteries and confirmed by taking apart my old black and decker and written right on the battery was do not discharge below 12.2 float charge is 13.4 and full charge is 14.8 and reconfirmed by what happened with my 2 everstart booster packs so I checked nature's generator and the same problem pepper reviews were great even on the Duracell 1440watt solar generator but that one had an additional problem which i learned from you Will David and the Professor a modified sine wave inverter but the nature's generator has good potential if they would fix the charging parameters the other flaws I can live with and the only way they'll change is if the big four reviewers would review their units you four have the clout to get them to change even with Will or you doing a tear down so we'd know if the pure sine wave inverter a good build quality and a pure sine wave but if I didn't know better I'd think you were all born into wealthy families you seem to think we can all just pay cash or borrow 8 grand to go solar but units like nature's generator have the ability to be a great starter unit with proper charging parameters it would be a good Entry level unit but change the pwm charge controller to mppt with 600 watt capacity and the ability to change the mppt to other chemistries and it would be a great starter unit add regulated 12 volt circuitry and USB quick-change and type C and it would be a very great entry level unit as it is I'm going to start cobling together something that will get me started
Inverter, BMS, charger if not part of the inverter... It's a shame that to get those scooter batteries into a more useful 7s or 14s configuration it requires tearing them down and rebuilding from the cell level. Remember that video and the truck comparison is for someone purchasing multiple tesla powerwalls. Probably someone like me.
I need to start a 2hp deep well pump. Specs say 14.1KW to start but about 10KW from a low frequency inverter will do it and then running is about 3kw. I have a sewage pump in the basement that is another 2kw running and I've never noticed the starting surge.
Piecing a system together with oddball components isn't practical, and then individual cells aren't worth the time and safety risk to me. I'm focused on big LiFePO4 blocks now, and considering an inverter upgrade. (I'm still rocking 1990s SW5548 from Trace before they sold to Siemens)
Hard to go anywhere if you're charging your house.
Jehu. This option is only valid for guys like you and me. We know a bit about everything and what we don't know we will youtube/google it until our brain hurts from all the different information. We will do the math and the science and most likely make it better than what the info provided because we know a bit about everything 😂. Not everyone has that tenacity and sheer determination to diy everything just so we could stick it to the big man😂. Greetings from Belgium, Europe.
a 500w bosch frame batt in the uk costs £700 fucking rip off and no one has managed to crack the can bus coms on the bms and newer ones are booby traped and die when power to the bms is cut pita!
A 12v 200ah chins or amperetime or similar is around $650 on amazon. I made a powerwall with 4 of them and growatt 3kw all in one inverter charger.
And with shipping - 100kwh of your batteries is $10,874.10 currently
thats a good price
Why, yes, of course. But most people aren't electrical engineers, they don't have boxes of batteries in their garage, nor they want to have. The price of a Powerwall includes installation, service and warranty. Almost nobody wants to tinker with high-power electrical equipment, people just want to install something that just works and can see pretty animations on their smartphone that show their power use from solar panels. I'd much rather get a Powerwall, though i could certanly pay you if you're willing to source, install, service and provide a smartphone app to monitor the system in realtime for many years.
I have more of a question than a comment. You were talking about the expense. Time and time again I here people say start small. Which is a great idea! My question is did you ever think about how large a system could be built from the current batteries but in such a way that a person could start small then add more here and more later so they could get to the bigger system for an end goal? It'd be awesome if someone was figuring that part out.
or connect a 4000 W inverter to your alternator👍
i know, i know... exit stage Left
It is the program that goes with the Tesla power wall that counts. It will cut the power spikes off of your load for your home reducing your utility bill. I don’t the exact kWh/$ will be saved, everyone’s power use is unique. Just saying it is more than just the battery in the Tesla powerwall.
Awesome
I can’t wait to see a build with the current batteries you have. Been watching your videos and want to build a power wall for my house. Still learning what I need to do.
Coming soon!
@@jehugarcia like tomorrow? Lol
Can’t wait
I find it funny that some people don’t realize much electricity they use till they want to build a off grid my best advice is learn about energy efficiency plus solar
Yep, installing smart devices or energy efficient appliances is also valid compared to installing solar. Although, once everyone uses EV I don't know how solar can be avoided.
There won't be anyone able to buy a Ford Lightning for $41,000. First that vehicle will have nothing in it, so when you add the power windows, etc, it will be $45/$50K. Then you get the dealer ridiculous mark-up and now your paying $60K...I will take the power wall and a cyber truck for $49K
To me, a 240v split phase inverter is table stakes. Gotta be able to run the furnace/hvac
ok, pay the big bucks then
I am waiting for the Gentry Solar 12k inverter…
then buy scooter batteries! :-)
Get 240v split phase /w scooter diy power wall!
Tell them the battery voltage requirement,
prior buying an inverter from them.
New 270 AH LiFePo4 grade A cells for $150 per KWh. Way more value in total cost of ownership, and far safer.
Let's do this!
The check out link took me to a battery clearinghouse error page.
click on the link on this video
@@jehugarcia I did. It took me to your site. I added 5 to the cart and clicked the "Buy Now" button. I was redirected to a battery clearinghouse error page.
Well shit, Apparently we can’t make a working website product page anymore , I keep telling myself we will figure this out one day…… yeah it’l happen
But how long do they last VS the Lightning battery. I bet not nearly as long. Plus you can tow 10k lbs and drive it. The thermal management for the truck is a great value at well. Will you need 10k in scooter batteries every 5 years. All my Escooters are dead after about 5 years and now I converted them to run on M18 batteries in series. 36v. Been meaning to try at 52 LOL
The cheapest model 3 the 35k car is currently 46,990 with a total price it says of 48,490....
Buy a fortress lithium batteries and sol-ark solar system
Link is going to BCH again.
Sorry, apparently we have no idea what we are doing anymore……
what about cooling though, scooter batteries arent designed for such loads?
I really want to build a battery bank . But I need to learn so much more 1st
Jehu- respectfully, iPhones (and Android phones) can multitask. So maybe this isn’t the best example.
The UI for this can be difficult to navigate, but in most cases it can be done. I routinely navigate and listen to streaming or even CZcams audio, and it switches back and forth between audio. In some cases you can tile the screen as well, but this is easier on a tablet.
Try listening to music while recording video….. try making a phone call while recording a Timelapse…. Try looking for directions or watching CZcams videos while flying a DJI drone….I can go on all day
@@jehugarcia point taken. I usually travel with a phone and a tablet, so I don’t hit these limits too often.
@@jehugarcia you shouldn't be watching youtube while flying a drone!
I was trying to watch a tutorial on how to fly my drone, but couldn’t because I was flying my drone
Is it true that you can only buy a Tesla power wall with Tesla solar panels now?
I really need to talk to you about 48 v system I need help in build something big enough to power 240v a stuff
Very cool. Something like this is in my future.
One thought. If there were two banks, each w 120V, with some inverter electronics for timing, could they supply 220 or 240V?
You being a factory, could probably build a truck frame, for less than $100, bare frame, but the cost to build a single one is very expensive, concidering the tooling cost, the material cost is very low.
Dang, we have Tesla Solar and Powerwall on order and I was about the cancel the order but our house is 100% electric with Heat Pump, Dryer, Range, Water Heater, EV to charge... Tesla Solar + power wall is quite a bit cheaper than the competition I've gotten quotes from so I'm not sure the DIY option would work for us. We're in San Diego so if you wanna stop by and rig something up for our 100% electric house, let me know ;)
Stick with what you’ve chosen, Tesla batteries are a bunch more reliable than any competition currently.

Sales person that tells the truth - how common is that? $100/KW can't beat it.
73K+ for 2022 lightning a year later.
There's no reason *I* wouldn't buy batteries and and MPP solar units for home backup... But you and I aren't the masses.
I have 10kw of grid tied solar with micro inverters. I can’t think of a reasonable way to keep the solar producing electricity during a power outage without a powerwall or other expensive device. So I just run the house off of 6kwh of scooter batteries until the grid comes back.
GS inverters will do 36 volts 6k low freq genetry solar
Genetry Solar is 120 and 240 volts low freq pure sine
GS 6k will do 8k by the way they have videos i have owned one for over a year way better than aims
you have 408k subs. you are not a nobody.
Jehu when are you making the video making a diy powerwall using the scooter packs you have in now ..The ones that come with with the little charging pcb????
I'm really looking at starting a project like this for backup power. I don't really want to go the gas generator route and would rather have a dyi powerwall to handle the occasional power outage. I've yet to see the power go out for more than 4 hours and checking my highest usage for A/C during the warmest month of the year I'm at an average of 56kwh a day.
Seeing that I can't run a central A/C unit I'm sure that average usage is even less.
I also hope to add on to it later with perhaps solar. But (and I'm hoping that this can be done) it would be done in stages vs dropping a ton of money on solar at one time (but I still expect to have it done within one year).
For 15 years Run 5 ton 6kw Load AC & 3Ton 4Kw XW4860 X 3 18 kw Pool & Hot Tub Too Very Little Load Shift In Summer Time .Add More Solar Panels 10kw To My Sys This Year @ Andreo Hope You Get It Done Too
With the low range, your wife will not be out of town with it.
It's such a shame they don't do much 36 volt equipment as it is the highest safe voltage for humans.
Nobody can get the Ford EV's without paying dealers 10k over the sticker price. There have been MANY reports on this!
i thought the truck was like 9.8 kwh for the truck vs 14.x kwh? in the wall? because the truck limits the max amount you can use in that mode...
But the 36V batteries make everything else hard. Is there a 36V UL Listed gridtie inverter?
Unlike certain channels you aren’t at the teat of OEMs…
100% agreed.
Yeah, I park my scooter outside
How can I get your battries in Nigerian
Hello can I replace 2 12v 7a battery of an ge ups with a 24v voltage scooter battery?
Yes, if you can find a 24v scooter battery, most of the ones I see are 36v
