Edit: The battery switch I used in this video is only rated for 48 Volts. So for 24 Volt batteries like in my case that's fine. If you are using it to disconnect solar panels however, the solar panels also cannot have more than 48 Volts!! A better choice to disconnect a solar panel from your solar system is if you use a DC breaker that disconnects both positive and negative wires. Get one that is rated 250Volts. Amperage depends on the size solar panels. But watch out with those DC breakers. If you wire them with the wrong polarity they will start burning. So always consult an electrician if you have doubts that you use the right components.

Hi, I'm a bit irritated about the electrical wiring and the protection. Maybe I got a bit confused. Isn't it that the MPPT takes up to 50A in from the panels but will only put 21A out at max with 24V? And the inverter got a 40A Fuse and your system is protected by a 100A fuse. Considering that a home circuit is only protected by a 16A fuse there seems to be a logical error here, or I got it wrong.
when there is no sun, some suoer inverter is better because it can be plugged to grid power and charge batteries. This way you have an uninterruptible power supply.
@@alfredkaserekasivanzire9488 ..If you're not already aware, may I caution you to make sure NOT to overcharge your batteries? Terms like "Trickle Charge" and "Float Charge" should be explored, as well as what's the minimum your batteries can tolerate discharge. (is it 11.5 volts per 12-volt battery?) Also, how to wire your positive lead to one end of your bank of batteries and your negative lead to the other end, so the 'charge' & 'discharge' cycles aren't from a single battery, alone...
I wish you all the best! A solar system is quite the investment in Money & Time, learning how to nurse & care for it...🇺🇸 😎👍☕

How can I buy andi stall my own solar pannells?
very useful video. no cuts. no editing. no bullshit. and she is really doing it. not showing only the results. congrats.
I am doing a similar project to keep all of my freezers running during a power outage. You are a clever girl.
I don’t know when it happened but congratulations on 1 million
You did a great job there, Lily.
I would just like to add something that I didn't notice you touch on in the video. It has to do with the hardware, the nuts, bolts, and washers.
#1 Regular steel hardware Has carbon in it. Carbon makes a high quality resistor. Never, ever use regular steel hardware. Be sure to always use stainless steel or brass hardware only.
#2 Never put washers between wire or component terminals, eg., between two wires or a cable and a fuseholder.
#3 Every connection has a volt drop or a little resistance. Reduce the number of connections to a minimum. Soldering wires to terminals reduces volt drop also.
I have seen components melted that came from the factory with improperly placed hardware. It did not take very long either. Attention to detail is very important, especially with high currents..
Beware of schysters that are copper plating aluminum for cheap cables and terminals.
Outstanding job Lilly, you did a better job than some electricians I use to know, I'm a disabled maintenance electrician in USA and I think you did a great job, you really did your homework, would like to know how well it works, but looks like it will do fine.
Hello jhon
My goodness I like how you explained each steps and it's not confusing. The other youtubers are usually males and they say it so fast, skips steps and do things fast making a newbie like myself get lost. Thank you for a great DIY video.
Nice project🥰
I would like if you can make a tour video of your lab tools and equipment.
Thanks ♥️
You were initially correct.
You did not need the thicker wire going from the inverter to the charge controller breaker.
There will only be 40 amps, not 100 amps flowing through it.
Being connected effectively to the battery doesn't mean all of the current is flowing through every wire connected to the battery.
Yes, I agree!
I would suggest going from the solar charger to the inverter connection is a bit strange, it works, but going from the charger to the battery makes more sense I think.
But yeah, there won't be going any 100A from inverter to the breaker that goes to the solar charger, that's for sure.
Exactly what I thought wire right the first time.
Exactly, at 22 minutes the wire size is right, as soon as that wire exceeds 50 amps the breaker will open, current will stop flowing and both wires on each side of the breaker are safe.
I love how you laid it out on a board, showing an easy schematic to follow, thanks!
Last week I learned a good lesson in Florida during Hurricane Ian. Always keep your solar charge system and battery at lest 4 feet off the floor. Also, make sure your solar charge system board has a shield that protects the electronic components from roof leaks.
Good advice! I keep mine at eye level (4-5 ft) so i can see my charge controller and monitor everything while sitting. Batteries are sealed lead/acid and only 6 inches from the ground. Greetings from Jamaica.
Hey Lilly! Just wanted to pop in and tell you how much I've loved your videos. I rarely comment on videos but got to tell you that you're such an amazing, very intelligent, strong, inspirational, and talented woman who I admire! Sending you MUCH LOVE FROM TEXAS! ❤️ And God Bless you
Wow Lilly, your work is so precise and AMAZING! What a great example you set!
She is great
I am jealous of all those tools you have!!! working with the right tools makes the job much easier!!!!!!!!! Great Job!!!!!!!!!!

Super video Lilly. I listen to you and Canadian prepper Nate. Keep up the great work! Thank you for all that you have taught me. Pete from Minnesota.
This lady did an impressive job!
Hats off! Her professionalism puts many other UA-camrs to SHAME.
VERY WELL DONE!
Excellent!
Nice nice nice! This video you should keep doing over and over. This will be the hugest life saver and it’s probably the easiest start to properly prepping. At minimal it allows you to store an expensive amount of meats without risking it going bad on a power outage.
Great Job well done and thanks for taking the time to show us.
Very good work Lilly, you are a good person to help your cousin. Your electrician will be pleased.
Huge amounts of off-grid solar power go to waste once batteries are charged. Water heating also stores that energy and can be direct DC. Lilly needs to design a diversion system, manual or automatic. I love her work in all fields.
In Canada you can hook up to the grid and sell the excess to the power companies.
@@Playingwith3D USA too with varying service charges and fees. Extra equipment costs plus price and rules changes justify caution when you're goal is survivability. You don't need to pay for power you don't buy. Do the math for your application.
I hooked ice maker to mine 🤓
@Teutonic Nordwind All true and worth doing. You will get a better return on your investment as most solar panels and batteries have a service life, age, and cycles. In your case, you probably adjust to conditions and power needs to get the most out of it. Charging all the new electric vehicles, lawn tractors, and such will increase your opportunities.
@Teutonic Nordwind You have the best kind of system, it meets your needs. The surplus solar power is easily converted directly to heat which you may have a use for, like hot water or heating soil or a concrete slab, things that have an inherent energy storage capacity. Just brainstorming here. Electric vehicles may soon take advantage of the surplus power.
Hi, Lilly. I'm from Puerto Rico Island. Thanks for your videos. God bless you!
This is my project for late spring 2023, so I am all over your video's, they are superb!
Please watch this video ua-cam.com/video/ZjATv33FwKk/v-deo.html
Wow, looks like you're planning ahead and writing about it.
P.E.A.C.E
@@SurvivalLilly If this video is named "(Part 1)", is the link you provided here considered (Part 2)???
Looks like you did an awesome job. It looks super safe to me.
Informative as always! I noticed how your skin is perfectly tanned, nice to see you in warm weather clothing. The summer will pass all to quickly!
Beautiful job Lilly. I just finished Will Prowse's book too. Awesome book. I have pulled together items for a 400W 12V 4.8K portable system for hurricane preparedness, to supplement my generators. If you can't get gas because no one has power you have to have a backup plan. Take this with a grain of salt as I am by no means that knowledgeable but the wire you ran from the controller to the inverter was probably fine as the controller is only using whatever amps it is rated for....no more. Also, tying the controller in above the fuse will had the controllers current to the overall current flowing toward the inverter and through the fuse. Maybe place it on the other end. I am sure folks will chime in and say I am FOS. I am glad I watched your video because you have a nice and neat layout to copy.
This is heaven. Yes i need to watch it a few times, but, i simply love the way you explained the details. Thku thku thku

WOW one of the best solar videos I have seen, very detailed information!!! thank you very much.
I have the very sam charge controller and it is AWESOME. You will love it. Just make sure you ALWAYS remove the solar 1st before turning of power. You can ruin that charge controller as I did. If you always do that I said you should never have any problems. I build my solar setup for my RV just the way Will Prowse says to. It has been working perfectly for 2 years now. You were So Smart to get Will's book. I did that same thing because I knew nothing about solar. Smart Woman. :)
Awesome.. Way to go Lilly⚡👍
The thinner wire on the circuit breaker is fine. It won't be supplying any more to the battery than the charge controller can output.
I thought so as well but Will Prowse is using a thicker wire too.
@@SurvivalLilly I don't know who will prowse is, but regardless, that wire is only carrying current between the charger and the inverter/battery. There will never be more than The 40A the charger can produce along that cable.
@@spr00sem00se i think you are right but maybe some codes require a thicker wire?
@@SurvivalLilly possibly codes require it. But if you have calcualted the length of the wire, and how much current the gauge used can take for the length, then its all good.
Ive got all my buck converters in house ready to make my peli case power pack / ham radio system......... son I will also be heading towards running refrigeration and hot water from solar :))
Hi Lilly thanks for being so detailed on your wire gauging. I love your videos.
I have some experience with batteries and such last 20 years making and fixing my Ebikes, but I learned a few additional things here, thank you for sharing your knowledge!
Best ive seen easy to follow.Clear explanation watching from NZ
Outstanding job Lilly definitely enjoyed it, full view and thumbs up,,👍
I worked at Best Buy as a MECP first class intaller and I am so impressed with your skills and attention to detail.
I was Sargeant general electrician at Walmart
@AgentOffice It's always a struggle when you work in the field between neat and fast. You always try to do the best work you can in the time frame you have allocated. Just beautiful to watch.
Very good illustration, and hands on explanation.
You are an electrician judging by the diversity of tools you have. Thanks for your well presented video 👏
From South Africa 👍
You are so smart Lilly, I could listen to you all day🤓
So smart and resourceful. Just love this!!
Great video!, I love your thoroughness and very detailed information. Also, love your hotness.
I love it how you have every tool for every job
Vielen Dank, du machst das wirklich sehr gut und auch gut nachvollziehbar da kann eigentlich nichts mehr schief gehen.Ich wünsche dir allzeit genug Strom, und einen schönen Tag 😉👍
Your electronical knowledge is just fascinating.
So good hearted to share this knowledge. I’m building one at the same time. Picked up some great safety ideas 💡 from watching this.
God bless
It’s fun to watch you mature. Really well done. A keeper.
As a tradesman from Australia who specialises in commercial kitchen fitouts and in-house manufacture, I'm humbled by your skills , your smarter than me , your tools are better than mine, I'm a long term sub of yours, and I own one of your first APO 1,s Thankyou
Thats because the project is planed and scripted, with all new tools with every new job.
You are such an Awesome cousin! Your family is blessed to have you 💞
on my early morning shift today (Sunday) randomly found your video... and literally bright my day !!! Thanks Lilly (Lilian?) .. Salute from London (a Chilean viewer )
Lily please upload the part 2 of your solar setup, I really like your part 1 which was done nicely 😀
Please watch this video ua-cam.com/video/ZjATv33FwKk/v-deo.html
I have built the similar setup as well. Specially, I used the similar DC transformer to transform upcoming DC voltage from the solar panels to 12V DC. I used 30A DC transformer. The only downside of this transformer is that you may lose some power between solar panels and inverter. Great Job.
Is there a Part 2 Lily? Thank you for sharing your knowledge and ALL the videos you have made over the years. Amazing woman you are. Cheers
Please watch this video ua-cam.com/video/ZjATv33FwKk/v-deo.html
@@SurvivalLilly Hi Lilly. What a wonderful work of art you have designed here. It is especially interesting to me, as I am building a system that is very similar to yours for my motorhome. The only difference is that at this point I am not using an inverter, so the breaker for that is also omitted. I am using a pair of 200AH LifePo4 batteries in series. The problem I'm having involves programming the Epever 40A controller with the proper values and settings in User mode. These are not well specified in the manual. I tried to access the video you link to in your response to another admirer in the comments. I am also very anxious to view a part 2 to this video and hope you will include your programming of the Epever in that video. Again, I'm very impressed with your talents. You Rock!
Best I have seen for beginners!! Thank you!
Agree w all the positive comments! Very informative and great to see the well explained step by step process. Thank u
Super job. I’ve built several similar basic systems. From the size of your board, I assume you will mount it vertically. You may want to check the inverter and charge controller manuals to see if vertical orientation is ok. The thrust bearings in the cooling fans in both devices are generally not designed for vertical orientation. Keep up the great work. Love your channel.
Wow , wow nice work you do,TO BAD YOU DON'T LIVE IN CODY WYO. I WOULD HIRE YOU TO HELP ME 👍🤠
Good point on fan orientation. I'm more familiar with larger equipment which is almost always designed for vertical orientation, as it aids in dissipating heat, esp from fans which will be oriented to blow up by manufacturer.
This is a great video. It gave me some important things to consider before build my own solar system. Thank you
Wow Lilly that was impressive. I've been off grid for 30 years in a northern climate. I really never thought much about refrigeration. People would always ask me well what you do for frigeration! And it was 40 below 0 outside! I'd just answer duh😮. But this is really good demonstration here because it's probably the most complicated part of setting up off grid. I like to keep things as simple as possible. AND I like your demo thanks❤
Hey Lilly, great work and great community you've attracted! You've earned a new sub, keep it up!!!
Very impressed !
Greaaaat video 👍 !
BRAVO!!! GREAT JOB! Thanks for sharing.
Beautiful work, Thumbs Up !
Absolutely loved watching this!! I’m currently building an off grid solar system to run everything in my house using lithium battery storage!! Thanks for the video
How many planets 🪐 will be there in your solar system?
@@ajarivas72 one- Uranus
@@ajarivas72😂
ok i have watched soi many videos on setting up solar and you by far made it easy to understand lol. thank you!
Wow excellent video, well explained ans simply described. Thank you.
That was a fabulous description & demonstration of everything. One little trick if people are wanting to reduce oxidation in the joins is you can put a little silicone inside the edge of the shrink tube & when it shrinks it squeezes the silicone out & makes an air tight seal. Very good for marine installations or areas you might have more moisture. For example i like to hose my batteries clean occasionally & it stops any moisture getting in.
Okay, I'll take one! LOL Nice job Lilly and awesome tutorial!
Very nice presentation. Good tutorial for anyone 👍
Thank you for this excellent video. It is an important project.
That looks great! The round metal terminals are called ferrules.
This is what I was looking for, yes. Thank you.
I like your videos Lilly because you are very smart. For me that makes you special, because not many people think the way you do.😊
Good staff,much appreciation
Excellent job! Thx for sharing
Nice work , I bought the same book a few months ago , will be watching fr0m Texas .
Excellent instructive video, Thank you.
Very clean Build Lilly!
Only thing I would change instead of dry crimping is to add solder due to fear of all the wires not touching as they should causing resistance additions in the Lines. Talked to my Buddy John ( Army Engineer ) He agrees as he works on Military builds ( 20 years experience ) I'd always trust his advice. Infrared camera did show a cooler wire condition and let us know what wires also need upgrades as we added loads to get close to 80% use of our system.
In this video your making it clear in my mind to understand hows to wiring from zero to working so i bookmarked this to my chrome to watched again and again everytime i open my pc, thank Lilly first time i see girls doing this interesting solar system
Thank you for a very informative video. Looking forward to part 2.

I was thinking that the wires looked too small even for a 24 volt system.
It looks like you chose good components.
Nice! Also there a whole group of DC low voltage standard products that will run with 24V dc directly. With some research one can find everything from ceiling fans to refrigerators that run directly from 24V batteries (less efficiency losses). Cheers!
excellent work Lilly, learned a lot watching this, I havev a 400w solar kit waiting to be put together... ty
Thank you very informative. Love your accent. I'm a newbie. And Will is great
Ps thanks from Canada
you do a pretty neat and systematic job
Just last night I put two spare Morningstar Sun Saver charge controllers into a double layered Faraday cage. These are lower cost, yet high quality and very reliable 12vdc charge controllers for smaller 400 watt systems that can charge two separate and different lead acid batteries at the same time. This way I have redundant systems, and several solar system designs that can adapt to different situations.
May I ask what the faraday cage is for? RFI protection?
@@bigdaadio.K2WW A Faraday Cage protects electronic devices from Electro Magnetic Pulse (EMP). EMP can be a result of the detination of a nuclear bomb, or CME (Coronal Mass Ejection). CME is a fairly regular occurrence that fortunately misses the earth more often than not.
Great content.
Thanks for your share.
In case of a zombie apocalypse...Lilly is on my team 😊
photovoltaic / solar thermal technician here: great shout out to Will Prowse and your video 👍
i am impress, you are a good student...good job lilly
willis book is great! Thx!
Excellent job 👍
#4 GA wire may still be a bit small for 24V and 2000 Watts. I have a 2000 Watt inverter with 48VDC input and have 1/0 welding cable inter-connects. Sie sind eine sehr talentierte Person, Lilly! It is also most important that your components are sided/rated for DC! Feel those cables when this is operating to make sure they are not running hot on your intended load. I have 3 freezers, 1 fridge, 2 computers and a pellet heater running of my system 24hrs/day on the freezers and Pellet heater & fridge and probably 12hrs/day for the computers.
super Job! Many greetings from Germany 🙂 ..am Ende des Videos habe ich gesehen das ich auch auf deutsch hätte danke sagen können 😁. Sauberer Aufbau. DANKE
Where did you buy your wire gauge? It looks VERY useful, and I would like to have one, too! BTW, Will Prowse's channel is awesome. I have been subscribed to it for over two years. I wish I had the funds - and an understanding better half - to do some of things he has demonstrated on his channel. I have been subsribed to your channel for maybe even longer. Great survival lessons and recommendations.
Those wires on both sides of the 50a circuit breaker are both protected by the breaker. They are in series. They will also have the same current flowing in them, on both sides of the breaker.
Kirchoff's law.
Good job, good tutorial, great information
That's an excellent set up! ♥️
Great vid.
I do have issues with the 100amp fuse but i am sure you will figure it out along the way.
You are amazing!
Wow, you're good. Enjoy the fruit of your labor
Nice work!!!
