In today's video we're going to learn and discuss about solar cryptocurrency mining and what parts will be required in case you wanted to follow along. This is going to be a really simple project that anybody can do and have their own backup off grid solar system mining cryptocurrency while you don't need it, until an emergency situation arises.

Backup power system that pays for itself!

I personally been mining cryptocurrencies for years and I love it! It's an awesome hobby and it's a lot of fun but one of the worst things is having to sell some of it to pay for your power but with this setup you'll never have to sell it anymore =)

interesting but why didn’t you get 300 watt panels instead of 100 watt? 300 watt seems to be the standard now

I personally use a grid tied setup to offset mining and bank power on the days that solar is running with optimal sunlight and temps. If you are off grid solar and batteries may be your only option, but for many people with grid tied systems,you might be better off just buying more solar panels or increasing the density with 300+ watt panels. I think batteries will become a viable option if John B. Goodenough gets his new solid state batteries to a point that they can be mass produced.

I actually had an older 280 I wanted to use for this project but due to living in the woods. I wanted to go ahead and max out the mpp all-in-one unit at 500 watts but I was going to have to order another panel.

Due to the mppt charge controller having a Max of 500 W, I couldn't order the exact same panel because it would put me over the 500 watt limit and then I wouldn't have the option of running it in parallel.

Just ordering two panels with shipping turned out to be more expensive than ordering the five 100 watt panel and they're more durable than the ones that are meant to be put on top of the house.

Grid tied is really one of the best options especially for large-scale mining and I've been using it for years but it does you no good those times that year when the grid is down. For the home systems, I've always recommended for people to have at least a couple of days of battery backup with there systems.

Although what makes this system a bit different than what I'm used to seeing and setting up. Is it can be set up in away that it's an off grid system only utilizing the grid as a backup so you don't have to stop mining when there's not enough power from the solar. Because the way it's configured you do not have to get any inspections and you can install it simple yourself.


For about $1,000 you can CPU mine for free for 8 to 10 years plus have an emergency backup power system that pays for itself.


John B. Goodenough is a legend and most people don't know that he invented RAM and the Lithium-ion batteries as we know it.

Great setup, and you can always expand your solar farm, your mppt is pretty good quality. But the Li-ion batteries, don't think they will run for 8 - 10 years, life cycle is much lower for them. You have to use them properly for them to last, do not withdraw all the juice from them, leave about 50% (in best scenario) then recharge, and up to 80% if you have to.  But anyways, good luck with your operation, watching this thread, let's see what will be your results  ;)

It's an interesting concept to build a off grid solar system and let a mining rig mining for years, but I have a question
Does it worth with the current prices, because I think the problem here is the cost of the batteries, I don't know exactly the lifespan of a battery

If you go with safe lithium iron phosphate (LiFePO4) it can be done. You can build your own for about $600 or buy them pre-built for about a thousand each or by the used ones like I did for about 300 to 350.

The big question is how much power do you use and how much battery do you really need? For example if you wanted to pull about 400 Watts 24 hours a day you would probably need about five or six of them (144 Ah).

As far as the battery life expectancy goes it could last anywhere from 10 to 20 years depending on how many times you depleted a recharge them. For an example if you were to mine with them and use all the energy and recharging everyday it would maintain more than 80% of its original charge capacity for about 10 years and probably only hold about another 60% of its original capacity over the next 5 years or so.

I hope this helps but did you give me a better idea what you're trying to do I can try to help you more.
