This panel can put out close to 100 watts kzread.infoUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.

To make it optimal, we could add a BMS (Battery Management System), with cooling controlled fans, vetilation holes, with screens, and below freezing temperature shut off. Oh, and don't forget a metal box... Looks cooool! Great video! Thanks for sharing!

Cool project, I always love DIY and people who share the knowledge. To everybody else on here, right or wrong, we should be thankful for people who take the time to do a good video and share their knowledge, even if it is wrong or we don't agree with it fully. You can either learn good things, bad things and takeway (if you choose) something from things like this. Having said that, I do disagree with a few things. First the price, you only mention the batteries, wood and glass as cost on your BOM. However, and you even link to these in the video, there are many other components on the BOM. For example, the battery holders link you provide, takes me to eBay where there are holders that hold 15 batteries for 5.99 each. To buy enough of these to hold 600 batteries, it would cost $239.60 just for the holders. On top of that, there are many other items, for example the fuses, buss bars, wiring, etc... Given that, and not even factoring in labor, I think your actual BOM is more like $600-$700 (and that is assuming you still use that overpriced piece of glass). Still not bad if you want to take on a project of this magnitude. Which brings me to another point, the labor. Do you care to share how much time it takes to pull apart all the laptop batteries, test them and then arrange/solder them all together into these packs? I would venture to guess it would take many, many days. Finally, as others have pointed out, there are things like UL listing, thermal and environmental concerns, etc... that are not factored in to your solution. I love DIY, but some things that may burn my house down, I tend to proceed with caution. By the way, if you burn your house down with something DIY like this (no UL listing, etc...) you may not even be covered by your home insurance. So, my summary, while the Powerwall is $3k-$3500, that is actually a good price when you factor the BOM, labor to build and other engineering concerns. Mike

I'm confused, did you go with 3s for 12v? 3s is really 10.8v or 11.1v. Most 12v inverters shutoff at 10.5v, meaning you probably will only see about a 50% capacity usage or less (depending on load) if you go with a 12v inverter. 24v inverter with 7S is a far better choice as the voltages are completely compatible.

The initial breakthrough of AC by Tesla a 100 years ago was to make electricity transmission possible. Now that solar panels have come so far, no need for power transmission lines. So, no need for AC-DC conversion portions of almost every electric circuit in every appliance (and the complimentary inefficiency!) Not only live on solar power, reduce the needed electric need by removing the DC-AC converters all over the house.

18650"s are fantastic on paper. The c rate is awesome, the lifespan is awesome. When you say lead is toxic I question what battery tech is more recyclable? I have not factored in the lifespan of lithium ion vs lead but i think the casing and electrolyte will become a small factor vs a 18650 cell packaging. Does anyone have any data that could draw a conclusion? Are there any recyclers that will pay for a core charge? I really think we should be looking for the next tech to fix both problems.

You need BMS, if your adding solar panels, you should also invest on MPPT charger controller. The inverter should be the size of whatever you plan on running continuously, take in consideration the surge power and it should be pure sine wave inverter. Good luck

You could add some "ultra capacitors" across the battery packs in each box if you have room. They have huge lifespan & can source hundreds of amps, so can ease load on batteries during startup of any electric motor or refrigerator loads especially in cold weather.

Liion does not explode infrequently, having Liion batteries like a 18650 charging with Positive facing down for a prolonged period of time is what causes batteries to explode as the heat has no where to go and will build up to dangerous temperatures which is what causes problem, not the technology itself. It is still well worth mentioning Liion requires proper precautions to ensure stability and proper operation ;but there is nothing about Liion as a technology that should be a cause for concern.

The right cable will be used once inverter is chosen, right now its a wooden box full of batteries with 2 cables sticking out of it.

LMAO. How long did it take to sort through 100-odd laptop batteries? I had not thought of this as a solution before, but it now seems reasonable to think one could power an off grid home on recovered laptop batteries. How much work is it to repair when cells fail? I assume there is an indicator on the fuse to let you see it's blown?

All good questions, all unknown until someone tries it out. Im hoping when cells go out they just trip the fuse and they are disconnected, not too much to worry unless too many of them start to fail, in practice who knows if thats going to be a pain. I have a 12v battery on my car built just like this, haven't had to worry about it for 2 years. So its a proven concept on a smaller scale so we'll see.

Very encouraging for a first time exposure to what it takes to produce and charge high capacity batteries at a reasonable price.

Great info! Love that microbus. I had a '59 23 window with the factory electric fan, and clock. No gas gauge though. Wish I still had it.

Dude, you have an amazing channel.

I really in love in such kind of stuff....... and like your channel and the idea. awesome work bro.

I have a friend that about 3 years ago had the Tesla wall battery house backup system installed OR almost installed. I would ask him every 3-4 months did the Tesla people ever get it in and running. He said not yet. I sent him an e-mail today, 3 years after my first asking him if it is up and running. Today, this afternoon, September 26, 2020 he e-mailed me back and said he cancelled the whole project. I don’t know if it’s the company that Tesla is using or Tesla itself. The point is his system got installed and working. I told him that Generac, the generator people have their system out and doing installs. They have been advertising their system all over the Houston area. I have a Generac 20KW natural gas whole house generator and it runs like a top. When the power goes out in 10 seconds the power comes right back on.

How many kilowatts do you need to run electricity in medium house? No AC no washing machine

Shared !! Can't wait to finish my own similar project on my channel!

Isn't it important to match all the cells performance?

Yes. He has no BMS installed. All electric vehicles with lithium batteries (and even phones and laptops) have some type of battery management system to monitor and balance the battery over time. Without that and with all of these random age cells thrown together, I think that long term some of the cells could get dangerously overcharged.

Brother you are a teacher, a skilled craftsman, a entrepreneur, a artist and all around model American Man! Thank you... i have subscribed... going to your channel now to catch up on all your videos! One request.. please name the components ("these guys") verbally or subtexts, either one would be fine.

i miss a BMS, that would greatly increase the battery life and safety.

Is plywood really a good material to store lithium batteries in?

Hi i'm interested in this power wall. If I want to charge this 600 battery pack the total pack capacity will be 1200 Ah and what is the most suitable charger to buy? As far as I know PowerLab 6 Charger can handle only up to 360Ah!!!. Please educate me. Thanks alot friend.

I love you. You are the future. Got here because of vice and you inspire me to learn about it and know about it because it’s something about the future we r gonna have to deal with

Would be interesting if you measured the actual battery capacity now that it's built... Curious to know how much it varies from the predicted capacity. Without that bit of information it's hard to know whether your strategy of using recycled laptop batteries worked. Personally I'm guessing your 2000mAh rating for each cell is off by a factor of at least 2. Also, stating the obvious here, but any lithium-ion battery bank is going need some circuitry to prevent over charging and over discharging. I'm curious what you'll use that can handle the amount of current this bank can provide. Not saying it doesn't exist of course, but without that bit of circuitry this isn't a functional battery bank yet. And I'd seriously consider using hardie board or similar for the backing (the side that touches your house) in case of failure. It's a cheap and easy way to at least somewhat compensate for the fact that unlike the PowerWall this has no thermal protection. And all that said, keep up the great work, love your videos!

NiMh batteries do not have issues with memory. That would be the NiCad batteries of the 80's and 90's. batteryuniversity.com/learn/article/memory_myth_or_fact

Awesome video, I am looking for a high capacity "whole house" UPS for computers/routers/switches etc. I wonder how I could wire a big pack to an off the shelf 24V UPS, or if there is another way.

That's my question... any answers??

No balance wire leads..? Also your description didn't list the "contact points" What kind of voltage is this? 52v?

Little 18650 or whatever have anywhere between 600 up to 2000 cycles Ignoring anything about BMS is bad But Bright idea and great DIY I'd really love to see this project continued

Where is the BMS, balancing?

Does it have a Battery Management System? Is there any software, which is deciding, if the battery is charged or discharged? Hope for you it does not fail and burn your house down! :D

You do need something to help it stick (flux or rosin core), as well as getting the metal tab up to the right temperature. Ideally it should only take a second or 2 to get it soldered, such that you don't transfer heat along the metal tab into the battery. And get a filter fan and ventilated room, because you'll be burning a lot of solder with hundreds of cells :)

Have you ever considered adding two alternators driven by the front wheels then connect a steppe transformer to help charge up the batteries for a longer charge life?
