Anyone crypto mining with purely solar power?

[doox00]

I have 10 extra 400 watt (500 watt with bifacial) panels after installing my solar system a few months ago. I have 3 eg4 6000xp inverters in parallel and ~170 kwh of battery storage with 60 400 watt (500 watt with bifacial) panels but want to keep this system separate. I am thinking of getting a 12000xp inverter and hooking the 10 extra panels I have to it, the only thing it will power are a few antminers (total of about 10k watts). I would run my battery bank to 12000xp also. I would not hook the grid up to the 12000xp at all, so the only time the miners would run is when there is enough juice in the batteries and probably only 6-8 months out of the year when there is enough solar to power everything.

Is anyone doing anything like this, how is your experience? Are the miners running fine on purely solar/battery/inverter power and respond okay with powering off and on when power is available to it? Which inverters are you running?

Lots and lots of juice required to run anywhere close to enough miners to make decent money.

yeah, 3 s19 pro's will do 15-20 a day, reason I would only run it with "free" solar power and no grid.

What sort of power do they require to run a day ... and is that $15-20?

I have an enormous amount spare during summer and have most panels disconnected as they are unnecessary most of the time.

the s19j pro's use about 2800-3200 watts each, each will produce (at price of btc right now) about 5-6 dollars per day, you can pick them up for 500-800 dollars used right now. So they use a ton of power and are not profitable unless you have super cheap electricity costs or free. Plus you have to keep them cool somehow as well. The newer antminers S21's which cost like 6-8k each new (the ones that run on 220v single phase) will do about 15-20 dollars a day using about 3500 watts.

It is not really about how much they produce per day unless you are trying to sell the btc right away for profit, its more about what the btc you mine will be worth in 1-10 years kinda thing. I just sold all my bitcoin throughout the 2nd half of 2024 (5 bitcoin total and 10 ethereum) that I had mined like 7 years ago. Now I want to mine on a small scale with the extra solar I will have ~half the year.

Thanks for the explanation and overview. Looks like the cost of the equipment is the stumbling block for me.

Like many things, the best time to get into them was 10 years ago (plus). And congrats on accruing 5 bitcoin and 10 ethereum, that must have been a awesome feeling having them in reserve ... and not a bad decision to convert them to dollars as well. I only bought into it about 6 years ago and have had a good increase ... but I'm not a trader ... just bought and held.

Keep us informed if you do go on using solar and in a small scale ... and good luck.

Yeah when I got into it 7 years ago I had wished I had gotten into it a few years prior lol. I just mined and held also, I only mined for about 6-8 months, I bought like 60-70 video cards at the time, spend like 30k on them, mined with them (all different alt coins and ethereum) and then converted them all to bitcoin and the 10 eth and held up to this point. Sold all the video cards and got like 15k back out of the 30k.. spent like 1200+ dollars a month on electricity and probably another 5-7k on setting the mining rigs up (motherboards/electronics/power supplies etc). I would guess I had about 30k invested all said and done after I was done with it.. ended up paying off thankfully. I kinda wish I did not sell all the crypto but I have a feeling another bear market is coming.. but who knows lol. I used the money to purchase a new home out in the country on some land and remodel/fixed it up some etc. Still have a decent chunk left that is just sitting in the bank earning about 5%.

If you have an extra 2000-3000 watts (you can put custom firmware on the miner and under clock or over clock the miners to hash faster or slower and use more or less power) of solar and pick up an antminer s19j pro for around 500 bucks I would jump on it, it will pay for itself in about 3-4 months (if you can run it 24/7) and then it is just free money for the most part after that if you already have solar up and going anyway.

Good on you man, love to hear stuff like this.

Goodness, I could drum up 5,000 - 10,000 watts during daylight hours for most of summer ... though winter time I pour all the spare I can into heating. Maybe I should look into it some more.

Does startup and shutdown cause problems or do they need to run 24 hours nonstop?

Yeah I will only run like 2 of them during the winter, will use one to heat my house and the other to heat the pole barn lol, turn off the mini splits then. Have to figure out a way to do that, these put off tons of heat and are really loud.

It is best that they run 24/7 without startup shutdown I am sure as most electronics prefer this, I am new to the asic miners myself so not super educated on them. I think for most of the summer I should be able to run them 24/7 unless we get many days of cloudy weather in a row kinda thing. I bought 5 miners total now, got them all for 500 shipped each, I am going to run them under clocked (lower hash rate then standard) and lower wattage, something around 2000-2300 watts each instead of the default of ~2900-3000 (model dependent on what the default wattage is) so they will hopefully last longer/run cooler.

Isn't anyone aware that BTC will be mined out and die? It's a time bomb.

Not in our lifetime it won't be.

Mining rewards include new btc issued AND transaction fees. As adoption grows transactions will increase to make up for the reduction from the 4 year halving….
