For emergency preparedness you can now buy a solar recharged battery bank that output 5 and 12 volts. 20,000 mAh. Peak output is actually 20 watts. It weighs 1.04 pounds and comes with four solar panels. Larger units have up to 37,000 mAh @ 13 volts and solar panels that will completely recharge the battery bank in four hours. YOU can put together a nice .01 to 56 MHz wire antenna that weights less than 2 pounds. You can take it with you. For roughly 12 lbs. plus 25 pounds of bush crafting gear you can run away from home.

You positive and negative feed lines should be on opposite side of the battery bank. It makes an even draw across the batteries.

One thing I found early is that companies like VmaxTanks make batteries specifically designed for use with solar panels and charge controllers. They have the screw terminals and such that make it easy and safe to connect the large cables needed for the high currents found in 12 and 24 volt systems. Corrosion is practically a non issue with these batteries and their terminals. I also use a contact grease to insure that the terminals don't have issues in the future. The other plus with these batteries is that they are sealed and do not need to be topped off with water like cheaper batteries that are not designed for solar charging and use.

The diagram shows both out leads (from the same end of the batteries. Shouldn’t the leads be at each end of the battery banks? Explaining a little more: wire series parallel but at the opposite ends, the positive and negative to inverters vs positive/negative leaving from the same end of the batteries. This is so that the batteries discharge at the same rate? Just curious

good job!

I was brought up to lay our batteries on an insulator. Never directly on the ground. See for yourself. Watch the voltage drop when placed directly on the ground and watch the voltage hold better when its sat on an insulator. I've seen the difference. Setting them on the ground will prematurely wear out your batteries. Js

if in a pinch you can use even copper pipe (preferably two or three sizes (say 10mm, 12mm and 15mm) shoved into each other, flattened on both ends and drilled to mount onto your clamp terminal. I even used copper water pipe pieces for my lugs...very nice, very cheap and even better then your standard crimp on terminals since all of them are pure copper...

Good stuff m8.

if i have 4 x 12V batteries and want to do a 24V system, is it better to hook them up into: 2 in series + 2 in series and those in paralel or 2 parallel + 2 parallel and those in series ? as allways there are folks that say the first is better and other say the latter is better ...

I have to be honest, I think you should consider redoing this video from scratch and don't worry about the thin wires being included in the video at the beginning. I appreciate your effort, but it would improve the quality of your video if you did that 👍

I'm thinking what the resistance on the thick wire will be to each battery

How many watt of solar output is needed to keep that bank charged? And how do I do the math to figuring out myself? Thanks

I don,t see any battery fuses, one per battery, without them you could end up with a battery fire.

Hi why did you not also change wire from controller to battery bank? It look fairly thin?

This is useful but why didn't you use blocking diodes to prevent one battery from charging another?

Hello! I need your help. I’m a little lost on exactly how everything works. I copied the way you wired the 12 V batteries together for a 24 V system but am I wrong and understanding that one side will give you 12 V still and the other side will still produce 24 V?

How would you recommend that I test an AGM lead/acid, 75 kilowatt hour battery pack? I know that is pretty big, but I need to know how to test the thing before I buy it used to know its health.

Hi there! do it matter whether you wire your panels parallel or in series depending on the kind of solar controller you are going to? IE. PWM vs. MPPT?

i see a problem with your system, i connected my 20 battery in a row like yours, but ran a paralell line down the middle for a middle 12 volt leg, since i had 2 12 volt inverters and 24 volt charger, they make a balance to keep the legs balanced, the way you have yours you cold have uneven voltage in each of your 24volt series bundles. add a line down the middle to tie them together and get a balancer.

Question: I am running a 12v system with 8 batteries in parallel. Right now, I have the Power coming in the 1st + battery and the - last battery and I have the out power reversed. This is corrected or is there a better way to do it. Thank for any help

I have a question that I have never seen brought up on these multiple battery arrangements. Now I have no experience with solar but as a mechanic for 30+ years, diesel light trucks have two batteries. When one goes down it will take the other one down and if you only replace one thee other will take down the new one. Thus both batteries are replaced together. Now those are lead acid batteries, does the same happen when that solar battery pck has one short out or no?

24v inverter can you connect more than 2 batteries on its in series

why can't you use flat stock? Maybe 1in wide x 1/4 thick??

Nice video, I just wanna ask these few question, the EPEVER Tracer A Series MPPT Charge Controller is 10A (1) I want to know if it has minimum wattage of solar panel that can be used with it as it is only 10A i.e. can this 10A charge controller work with 1000watt solar panel (4 X 250watt solar panel) (2) I have one 200AH battery Deep Cycle battery 20A PWN charge controller. How many watt solar panel will i need (minimum) to work with it. (3) If I have a 12V system i.e. 12V inverter, 12V battery and 12/24V charge controller. can i use a 24V solar panel on this setup (4) How does how big the Amps of a charge controller affect the working of the charge controller positively Thanks

I have 24v 2000w inverter and I have 4 batteries 200ah each. I want to connect all these batteries into this inverter, it is possible for me to do so or how can you help me please

I think this battery connection has a problem. In my think outage will be 48V. Because this connection both (serial & parallel). am I right

Thank you the help I needed is can I do it to run 12v as all my item I have are 12v but was only running of a small 20w solar panel and 2 mobility scoter battery's BAT/UPG12-50 12500 50ah each but I had a good deal come up for the Great big 260w panel at only £109 and £107 for 2 new 125ah battery's great price for me in the UK

3 advice: bus bar, bus bar, bus bar. the way you connected the batteries (you chose well with the bigger sections of the cables) your batteries will never charge equally. the last one in the chain will always see a lower voltage because of the voltage drop over the length of the cables between the batteries. take a copper or aluminum bar, bring the main cable from the charger on that bar. from the bar you make one separate cable to each battery, all of the same length. In general, parallel batteries are never as good as bigger batteries. when you have to replace your bank (hopefully not soon) have a look at big capacity 6V batteries or even 2V cells.

i would not let you weed my garden ,i seen it and heard it all now ,clueless comes to mind .well i had a great laugh watching you at least if nothing else cheers.

Do you get any gas from the battries when charging

A word of caution, there should not be any flammables around your battery bank, noticed you had a gasoline container within 4 feet, I''m hoping it has never had gasoline in it. A spark will ignite gas fumes in an instant, and just hooking up batteries will cause a spark. Just trying to be safe so you can enjoy your time with your kids.

How many batteries can you connect to 1 charge controller?

What brand and type are your batteries?

I am looking for some help I will have 2x12v 110am battery's and I want to use it all on 12v but my new panel will be PMPP 260w VMPP 30.7v imp 8.50A 37.8V VOC UL 1703 600 UL 17031 5A can I do this for 12v please help

Hey mate way to much bloody crack, butt one hell of a good job ol chap

Why did you wire the batteries for 24 volt if you were going to only connect half of the "12" volt to the 12 volt inverter?

i laghed when i seen ur 16gage wires... im still laughing... inverters beeping. Load off at 10.7v (dumb)... lmao... then it would take u 3 days to get full charge again.. i thought i was hard on my battery bank.

Please let me to teach me for this lacture

30A 12-24V/48V Solar Regulator Solar Charge Controller this is it

Are you an electrician or an electrical engineer ?

Your hole setup looks like a def trap to me.

As soon as I saw this, I was taken back to the days of Kenny Everett's DIY man Reg Prescott: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FwBjLCAodLw.html

In you pucture in the beginning it only shows 8 batterys, but i the video you have 8 batterys

How the hell that didn't blow up I don't know

DYNAMIC Risk Assessment.. OMG it looks like you have the batteries up against the walls, is that wall metal?. If it is, that is a big health and safety concern to have the batteries and heavy gauge wiring near it in what looks like a big metal container along with liquids in close proximity. You have a cabinet on you right hand side with what also looks like liquid along with other loose junk up there. All it will take is one bump from you wile you working with the batteries for it all to come tumbling down with can start a domino effect of horror. Spark,fire and so on the what looks like wood under you batteries will only help the fire burn and spread faster then you can blink. If the explosion thus not kill you the smoke and the heat from the fire will.. any of this sinking in yet?. For others, if not for your own Safty, I hope my comments have shocked you enough for you to put Safty first when working on this type of project. By the looks of your setup, it’s a matter of life or death. I’m sry to say that this is a good video to show students what not to do wile working on these systems.

Lol safety checks? Look at your own video and you will see what I’m talking about. Are you trying to say I’m not seeing the danger, or are you just blind to it? the fact you can’t admit to it is a more scary situation, as this is the first step changing the wrongs

Please do not play power systems you sound you aren't qualified to be installing .. Especially when AC and DC charging .. Sounds like you been in the Reno game..

So amateurish on so many levels.

You need to take this video off, maybe try something else?

I have to say something here. I understand that your a stay at home dad and are sick. but asking for a new computer because you cant afford it? you shouldnt even be doing solar projects. I totally lost respect.
