Hey brad newbie here was wondering if you had the time to talk about mining solar, more in the aspect of electricity bills and the profitability from the solar, would love to hear from you soon brother thank you for the video
It's great for a small miner. An S21 will require 4.6kW of DC power. That's a lot of amps, but your idea is still solid. Just needs bigger parts. Should I design it?
Thanks for the content Brad. I am in the process of figuring all these out. Your video gives a really good idea of the fundamentals on the setup, and I really thank you for this. Currently at around 750-800watts, and my electric cost is crazy expensive (EU). More please!!?? 🤷🏻♂️😅
Yes you say true. Convert DC to AC and back to the Rig again with DC current this way too lost of power. Thanks for your idea direct use of DC power is the best.
I thought about doing this awhile ago but didn’t know mining mother boards didn’t use the 24 pin it must convert 12 volt to 5 volt 3.3 and 1.5 for the cpu in the board with a regulator I’m glad i found this video
wow man your a life saver! such a good idea. i have a 3.2kw solar system, your right the loss of power using ac power supply is terrible. ill have to get this MB and try this out
Hey Brad, I'm really impressed! This is exactly what I'm looking for. I would like to build this system by my self - usung your nice tips. Is it possible to get in contact with you directly?
great video, love seeing solar use while cutting out the inverter. I've been curious about running hashboards in series on the raw 48VDC (ie 4 12VDC hashboards in series)
Why wouldn’t you just parallel more of those batteries use those extra panels and run through the night instead of having to do all the turn on and turn off in the morning and night
I do have a larger setup that does just that. I just wanted to show people how easy, and inexpensive it is to get started. Also right now with how low profitability is, it's going to be hard for people to justify the cost of enough battery to run through the night. For example I have a system that runs through the night with three RTX a4000's it has 8kw of battery, that's the equivalent of 13 of those batteries in this video.
You should use a Fly back Diode for the Relay, because it can Store much Energy and if you diaconnect it it gives a big voltage Spike, witch can destroy the load stage of the solar charge controller
Yes this is normally desired, however this relay has a built-in economizer circuit that greatly minimizes the holding current, and includes the flyback diode on that circuit.
Brilliant analysis!! I'm researching & learning solar so I know mono-crystalline panels are best. Ever experimented with Cigs Amorphous panels for early morning late evening power that the mono and poly panels can't compete with? I realize we have 500 plus watt panels which are more efficient than Cigs but they are getting better again due to Texas Instruments and others. What I like is they perform in low light conditions where the crystalline panels are lacking. Would love to see a video on Cigs but don't go buy panels, maybe a company could loan you a panel or just review the market and tell us what you think.

Nice idea. You can go up as high as 14,4V if stacking a few old car batteries toghether, and those are pretty cheap to get now that everyone has Li-Ion and they are interchangeable if the event of a unit dying out, which can happen a lot depending on the age of the battery - but that's ok considering the low cost. The only thing to consider here would be that when the batteries go low the pc should power down before they are completely drained because low voltage can stress components and the batteries itself, some auto-turnoff feature is required. Note: Battery port will act just as Load port once batteries are drained, this is because the battery loads up as much as possible and at the same time gives out the required amperage of the components, if the output threshold is higher than the input, sooner or later the batter port will only act as if the load port was connected, therefore you would have to actively monitor the voltage and cut off when under a certain level bacause if you don't you risk component failure.
I have an older Power Boost MPPT 60A charge controller that didnt have Lithium or Lifepo battery option back then and a 100AH lifepo too which is not connected to the controller. Can I still use this system somehow to power a mining rig ? I have all these components (no mining rig yet) that are sitting being unused and would like to play around.
@@Zeuswashington Depends on the power draw of your rig. For example lets say your rig uses 300w continuously. Lets say you have a 100ah 12.8v battery. 100ah x 12.8v = 1280wh. So we take 1280wh and divide it by your rig power of 300w, and we get 4.2 hours or runtime. So not enough, but if we triple the battery capacity to 300ah we get 12.6 hours of runtime. So depending on the season, and your locay that might get you through the night so the solar can take over in the morning.
I have been thinking of this but my house is already wired via a 24V inverter. Except if there is a way to set the DC load back to 12V or 13V while the input power is 24V. If not, maybe DC to DC Converter will do the Job. My Rig takes up to 650W mining Kaspa. Is there any 1000W DC to DC converter? My Solar Panel is 300W x 4.
You can get 710w residential for about $180 (post-tax) as well new. Get 2-4. And ur steady for something decent. Im researching rn to start my first little dealio. Good luck to all. Dont sleep on this.

Where can I find a sizing guide for running a small ASIC 24/7? All I really know is the wattage of my ASIC, but I don't know how to size the rest of the system.
My setup burns 650 watts, that's comprises 3 cards plus about 30 watts for the rest of the system. I have plans to keep expanding, especially if I don't have to pay 100% of the power, and I want to run 24/7. I can supplement the overnight power needs with wind generators, but I will likely also need to switch to grid power from time to time. Got any recommendations on equipment for that?
Yes, I working on a simple grid fallback. So you run off solar when available, and fallback on the grid when not. The way I'm thinking might be super simple, and maybe no battery at all. Stay tuned.
I've always been an electrical tinkerer, even from a very young age. Yeah, I've pretty much realized this is not easy for everyone, and I'm actually trying to come up with some simpler plug-n-play solutions. Stay tuned!
hes right i found company that knocks down house to rebuild and i just asked him and he had huge lot full of them,so was getting 40 volt 300 watt panels for 40 dollars australianthe most costly thing is the higher voltage mttp charge controller that can do up to hundreds of volts but dont have to go that high 48 volt one be cpl hundred dollars
i even got a few 86 volt 150 to 180 watt for memory,they full commercial grade ,the cells are sandwhiched between two really thick 5mm sheets of glassand had really thick premolded cables comming out,wish id benn able to more of those the cell was printed on one whole sheet
Yup! BTW you can run them in parallel, and you wont have to have high voltage controller. You will however need to fuse, or use breakers on each parallel connection. Honestly I prefer to stay less than 100v to minimize arc faults.
Great video! Can I ask what the main purpose of the relay is? Can this same setup be done without the relay if I am looking to run enough batteries and panels for an always on rig?
The load port on the MPPT controller can only handle 10 amps (I think 15 max) which would limit power to the mining rig at 10a x 13.8v = 138w . Using that particular relay wired in allows 500amps, which is overkill but gets you well passed that 138w limit.
Thanks for the video! One thing i don't understand, how is that relay allowing you to get more than 15A from that DC output? What kind of relay is that? More explanation from that part would be much appreciated 🙏 Thanks again
@@BradCagleoh I’ll have to look into more coins, I’m actually building this Solar miner right now. I just got the relay and other parts today. I have one more questions, why did you use that copper bar from the relay to the busbar? Not just a wire?

Thank you Brad Cagle you have sparked an idea with this method of Solar Crypto for me that i will for sure try, will share later once i know it 100% Golden.

@@evilmario5649 Rad, I would love to see a video of it when you get it working. I did a video last year with a D3 running directly off 12v battery ruclips.net/video/xa5ChO0iynA/видео.html
Hi Brad. Great video. Thanks for that. 😀 I'm very curious if you can share little bit about your own complicated setup? I just wanted to get a picture how can we run many mining machines with this setup easiest way possible. Because the way you show can be a good solution but to run many machines at same time can be an issue, so therefor I would like to know, how do you do it? Thanks 🙂
The mother board he is yousing is mining board 12v version it was intended to be mined whit bitmain power supply and 12v power supply soo the 12v board is berfect candidate for DC mining
I suggest trying it on minimal hardware at first. less painful if you make a mistake :) When I'm setting one of these up I start with one gtx1060, or some older card, and let it run for a week to make sure everything is working properly.
was working fine for awhile but getting error code fault prompt dc output short circut. Took whole rig apart several times and put together any ideas on solution?
Just a question, 12v is the least efficient for running off solely the battery right, So if you ran this without the relay on a 24v the amps would be around 4 and 48v would be 2?
@@BradCagle awesome you got my like and sub and I'll be checking those out as well. Thank you! Game changer as I have half the equipment already. No lithium yet but decent 200ah agms
Can I run a simple 24 to 12 volt converter off Amazon and connect it to the load line... I want to run higher watts, even if it is only for 6 hours.... I commented a older video that showed your 48 to 12...
Yes, you can use the amazon 24 to 12v dcdc converters. However I personally would not trust my expensive GPUs with those. Reason being if they fail, your mining rig might get the full 24v. The best way to do it is to use galvanic isolated dc/dc converters, this means there is no direct link to the higher voltage, not even the ground. So look for this kind of converter. The ones I use in my other video you commented on are 48v to 12v 1/4 brick isolated DC/DC, they are modules used in telecom. This is the one www.mouser.com/ProductDetail/826-ADQ800-48S12B-4L Now these are modules, so you have to build a few supporting components around it (a few caps). You might google search "galvanic isolated dc/dc converters" and find something ready to go.
Thanks, Q. So how is this wired up? So power from the mppt battery outlet runs to the relay and the load power runs/connects whereto the relay awell somehow? I'll like it but I have no idea how they work ha ha, please help 😔.
I think running the gpus directly on battery voltage is a bad idea you should add a dcdc coverter to get stable 12v because the battery voltage is changeing with state of charge of the battery
So @19:30 you'll see I have set the upper, and lower voltage. Lower set to 12.40v, and charge is set to 13.70v This is the max high, and low voltage the equipment will see. So as long as you're comfortable running a bit higher than spec. Up to you, I've done it a lot myself without issue YMMV. I'm about to do another video that uses 48v, with a 48v to 12v Isolated DC/DC converter. This will be the safest, because an isolated DC/DC will not allow the higher 48v to reach your 12v equipment even if it shorts, etc.. Standard non-isolated DC/DC converters can easily short a MOSFET then deliver the higher side voltage to your lower voltage equipment.
Depends on the size of the battery, and the load. For example this 50Ah battery has 640Wh of energy when full, so if your load (miner) draws 320w tha battery would last 2hours
@@Vaba-Mees LOL, yes. This is why I suggest only mining during the day if you wan't to use solar. The battery investment is not worth it right now. Maybe when we're back in the bull market. The other option is to have it switch to grid when the sun it gone.
This is only 1 way to go but is it safer to put 1 good 12v PC power supply into the chain to just make things safer. I mean going like this straight is so risky?
Yeah, I'm not sure how to quantify the risk. Maybe it's as risky as taking a lighting strike to your grid? Some say it's risky just to mine on your gaming GPU's :) We must assume risk is always there, now what is the risk level? This is the question brave risk takers answer :) That being said my main fear is the charge controller shorting, and allowing the higher PV voltage through to the GPUs. I've had this happen on a different controller, no GPUs attached luckily, just battery at the time. You can use a device called "victron battery protect" it will disconnect if it detects voltage >16v, which still may be too high, but may save you. On my other larger system, I use 48v, and a 48v to 12v isolated DC/DC converter. The isolation makes it impossible for the higher voltage to reach the GPUs.
@@BradCagle As i said 1 gold plated pwr supply can resolve the issue dunno why the presenter didn't include one to the story, it would be great to see how it works. Pwr supplys have oc curent protection by them selfs so if soemthing happend they take a hit not the other components. Thats all!
@@blekibabic I'm the presenter, and I think you're missing the point. Let me clarify, If you use a PSU, you also need an inverter. These two components together will waste 20-40% of your power. The point of going direct is to minimize this wasted power. Is it more riskier? Possibly. As I said lack of isolation would be my concern. In the PSU you mentioned, it has isolation via the ac transformer, so presumably it may be more safe. At any rate, i'll continue with these experiments, and post videos as I come up with better solutions based on my results. Thanks

Hi Brad, very good video. I guess when it shutdowns just with a switch there are no issues. But not clear when it boots up, how it does auto mining...

I can supplement the overnight power needs with wind generators, but I will likely also need to switch to grid power from time to time. Got any recommendations on equipment for that?
Yes, I working on a simple grid fallback. So you run off solar when available, and fallback on the grid when not. The way I'm thinking might be super simple, and maybe no battery at all. Stay tuned.
@@BradCagle Ok, great. Thank you.

Do you have electrical background? I see a lot of cables looks a little more advanced not for a biginners
I've always been an electrical tinkerer, even from a very young age. Yeah, I've pretty much realized this is not easy for everyone, and I'm actually trying to come up with some simpler plug-n-play solutions. Stay tuned!
hes right i found company that knocks down house to rebuild and i just asked him and he had huge lot full of them,so was getting 40 volt 300 watt panels for 40 dollars australianthe most costly thing is the higher voltage mttp charge controller that can do up to hundreds of volts but dont have to go that high 48 volt one be cpl hundred dollars
i even got a few 86 volt 150 to 180 watt for memory,they full commercial grade ,the cells are sandwhiched between two really thick 5mm sheets of glassand had really thick premolded cables comming out,wish id benn able to more of those the cell was printed on one whole sheet
Yup! BTW you can run them in parallel, and you wont have to have high voltage controller. You will however need to fuse, or use breakers on each parallel connection. Honestly I prefer to stay less than 100v to minimize arc faults.
Great video! Can I ask what the main purpose of the relay is? Can this same setup be done without the relay if I am looking to run enough batteries and panels for an always on rig?
The load port on the MPPT controller can only handle 10 amps (I think 15 max) which would limit power to the mining rig at 10a x 13.8v = 138w . Using that particular relay wired in allows 500amps, which is overkill but gets you well passed that 138w limit.
will the battery last doing this everyday? Like its going to run out during night and then charge back up.. after 1 year will the battery be alive :D
I'm curious as to how you use 48 volts and convert it to 12 volts in your larger system? Are you using a buck converter and if so which one? Thank You
I want to know what a buck converter does turns DC to AC ? Lowers the volts? and make a consistent energy supply?
i am watching this video everyday,i enjoy it
Glad you enjoy it!

How long does it take to mine for 24 hours
turn up the memory to +1600 and set the core to 1000 fixed core. youll get better efficency should go upto 85mh at 90w, true ergonaut right here.
Thanks for the video! One thing i don't understand, how is that relay allowing you to get more than 15A from that DC output? What kind of relay is that? More explanation from that part would be much appreciated 🙏 Thanks again
Ok i read the selling page of that relay, now is a bit more clear, sorry for the stupid question.
How much did you earn for day?
Is Ergo what you primarily mine? Or are there other coins?
I've been mining mostly Dynex. I feel "proof of useful work" has a lot of potential. But I could be wrong :)
@@BradCagleoh I’ll have to look into more coins, I’m actually building this Solar miner right now. I just got the relay and other parts today. I have one more questions, why did you use that copper bar from the relay to the busbar? Not just a wire?
@@DominicRoyce It was mostly out of convenience, and I think I already had it form another project. Wire will be fine.
@@BradCaglehey sorry for all the questions, but I got the 60A version of the charger. Why am I not able to change all of my settings. I can only do: UV Recovery: 13.4V

OV Protection: 14.5V
I can’t change it past this, and I don’t know why.

Hi Brad. Great video. Thanks for that. 😀
I'm very curious if you can share little bit about your own complicated setup?
I just wanted to get a picture how can we run many mining machines with this setup easiest way possible.
Because the way you show can be a good solution but to run many machines at same time can be an issue, so therefor I would like to know, how do you do it? Thanks 🙂
The mother board he is yousing is mining board 12v version it was intended to be mined whit bitmain power supply and 12v power supply soo the 12v board is berfect candidate for DC mining
heyyyy!! brad excellent video very instructional high five! inspired me to go for it!
I suggest trying it on minimal hardware at first. less painful if you make a mistake :) When I'm setting one of these up I start with one gtx1060, or some older card, and let it run for a week to make sure everything is working properly.
was working fine for awhile but getting error code fault prompt dc output short circut. Took whole rig apart several times and put together any ideas on solution?
Are you saying converting dc to ac to power mining machine will result to alot of loss
Just a question, 12v is the least efficient for running off solely the battery right, So if you ran this without the relay on a 24v the amps would be around 4 and 48v would be 2?
Correct, but then you need a buck converter to bring the voltage back down to 12v. I have other videos doing this with 24v, and 48v.

Can I run a simple 24 to 12 volt converter off Amazon and connect it to the load line... I want to run higher watts, even if it is only for 6 hours.... I commented a older video that showed your 48 to 12...
Yes, you can use the amazon 24 to 12v dcdc converters. However I personally would not trust my expensive GPUs with those. Reason being if they fail, your mining rig might get the full 24v. The best way to do it is to use galvanic isolated dc/dc converters, this means there is no direct link to the higher voltage, not even the ground. So look for this kind of converter. The ones I use in my other video you commented on are 48v to 12v 1/4 brick isolated DC/DC, they are modules used in telecom. This is the one www.mouser.com/ProductDetail/826-ADQ800-48S12B-4L Now these are modules, so you have to build a few supporting components around it (a few caps). You might google search "galvanic isolated dc/dc converters" and find something ready to go.
well, 12v battery is 12.8v and fully charge at 14.6v.
So what we need to mine with 8 3070 that use 120w each.
how big amp battery i need to run 12hour night 1500w mining rig ? 200amp battery?
1400Ah so 7 of those 200Ah battery
@@BradCagle lol :)
Thanks, Q. So how is this wired up?
So power from the mppt battery outlet runs to the relay and the load power runs/connects whereto the relay awell somehow?
I'll like it but I have no idea how they work ha ha, please help 😔.
So your telling me using this solar panels you don’t pay no energy bill or con Edison?
Amazing video and eye opener thank uou boss

Great video!! Thanks for the content
Glad you enjoyed it!
is this usual 50a car battery?
No it's a LiFePO4 battery for energy storage. Car batteries are really only for cranking over the engine.
How do you convert the 48V you're getting from your solar panels down to 12V DC? Is that all taken care of via your solar charge controller?
Yes. The charge controller converts the PV voltage down to the battery voltage.
@@BradCagle Okay, thank you.
From the mppt charge controller ,it converted the 48 volt of the solar panel to 12 volt to charge the battery
I think running the gpus directly on battery voltage is a bad idea you should add a dcdc coverter to get stable 12v because the battery voltage is changeing with state of charge of the battery
So @19:30 you'll see I have set the upper, and lower voltage. Lower set to 12.40v, and charge is set to 13.70v This is the max high, and low voltage the equipment will see. So as long as you're comfortable running a bit higher than spec. Up to you, I've done it a lot myself without issue YMMV.
I'm about to do another video that uses 48v, with a 48v to 12v Isolated DC/DC converter. This will be the safest, because an isolated DC/DC will not allow the higher 48v to reach your 12v equipment even if it shorts, etc.. Standard non-isolated DC/DC converters can easily short a MOSFET then deliver the higher side voltage to your lower voltage equipment.
how long battery last if no sun?
Depends on the size of the battery, and the load. For example this 50Ah battery has 640Wh of energy when full, so if your load (miner) draws 320w tha battery would last 2hours

@@BradCagle i need some big battery´s :)
@@Vaba-Mees LOL, yes. This is why I suggest only mining during the day if you wan't to use solar. The battery investment is not worth it right now. Maybe when we're back in the bull market. The other option is to have it switch to grid when the sun it gone.

You can get rich, or you can't. So I choose stability and earn only on Crypton cryptocurrency.
This is only 1 way to go but is it safer to put 1 good 12v PC power supply into the chain to just make things safer. I mean going like this straight is so risky?
Yeah, I'm not sure how to quantify the risk. Maybe it's as risky as taking a lighting strike to your grid? Some say it's risky just to mine on your gaming GPU's :) We must assume risk is always there, now what is the risk level? This is the question brave risk takers answer :) That being said my main fear is the charge controller shorting, and allowing the higher PV voltage through to the GPUs. I've had this happen on a different controller, no GPUs attached luckily, just battery at the time. You can use a device called "victron battery protect" it will disconnect if it detects voltage >16v, which still may be too high, but may save you. On my other larger system, I use 48v, and a 48v to 12v isolated DC/DC converter. The isolation makes it impossible for the higher voltage to reach the GPUs.
@@BradCagle As i said 1 gold plated pwr supply can resolve the issue dunno why the presenter didn't include one to the story, it would be great to see how it works.
Pwr supplys have oc curent protection by them selfs so if soemthing happend they take a hit not the other components.
Thats all!
@@blekibabic I'm the presenter, and I think you're missing the point. Let me clarify, If you use a PSU, you also need an inverter. These two components together will waste 20-40% of your power. The point of going direct is to minimize this wasted power. Is it more riskier? Possibly. As I said lack of isolation would be my concern. In the PSU you mentioned, it has isolation via the ac transformer, so presumably it may be more safe. At any rate, i'll continue with these experiments, and post videos as I come up with better solutions based on my results. Thanks
