Title: How many bitcoin miners can i have?
Post by: UnknownBTC on May 09, 2017, 11:29:48 PM
So yeah as the title says im about to start a "large" mining operation in South Florida and as im looking for a warehouse to put my miners i'm trying to figure based on the electrical set up of the place how many miners can i run i know that i need and electrician if i want proffesional help but i would like to have an idea before telling the guy to come as i have to pay him every time.

Thanks in Advance, i'm talking about S9's 13.5TH just in case

Sigh. Look at the Bitmain specs maybe?.....
Nice round ball park is 1,500w per-s9. Will need 208-240 volts and with that voltage the amps per-miner =  1500/voltage.
Your turn.

How about ordering just one unit then test it out at your place before going in bulk?

I already did that a long time ago now im ready to go in bulk

Thanks for the info making it clear for everybody else:

1W=1V.A

so

Amp per miner= 1500/240=6.25A ?

If you have already had it for a while, how come you don't know its consumption figure? By testing I didn't mean to just plug-and-play.

Certainly don't want to be rude and I'm not intending it so but if you are needing to ask on a forum how many miners you can have in a warehouse of a particular size, perhaps you need to think smaller for the near-term. Not sure what #'s you ran before. You will need to put more details in your post before you can get any useful info back.

My questions would be before I asked any electrician to come out in no particular order....

What is your budget?
What number of miners are you thinking total?
What size (aprox) warehouse are you looking at?
Will you be setting this up/monitoring/servicing this by yourself?
What is your electric cost going to be? Commercial rate or what?
How do you plan to provide cooling/dehumidifying etc.?
Security?

If I had more time to think of important questions I could prob come up with a few dozen more.

When you say, "I already did that a long time ago now im ready to go in bulk", what number of miners were you running? Were you running them at home?
Depending on your answer to the number of miners you ran before, you may want to think of running 10-20 in a space that can be expanded and (accommodate electrical expansion as well), before thinking in terms of 100 or whatever amount you are considering.

There are just too many questions that need to be solidified before thinking of putting out so much money and committing yourself to what could be a money-pit at the outset.

Also, if you want some more detailed info/feedback from here, you will need to provide much more info to get some reasonable/reliable/helpful answers.

I'm not saying any of this out of experience. The most miners I have run at once are seven, four S9's and three S7's. I'm just saying this as an IT guy who knows that anything being planned on a large scale needs to be planned for thoroughly and accounting for any and every possibility or problem. Because, as you probably know, anything that can go wrong, may go wrong all at the same time. LOL
Good luck.

P.S. Again not intending to sound rude, but if you are concerned about having to pay an electrician for just a visit to your potential site, perhaps you may need to reevaluate or down-size your plans.  :)

Actually your example should be 1W=1V*1A but yes 6.25A @ 240V. @208v the draw is 7.21A -- Always find what the minimum voltage to the area is and use that for sizing the service needed.

As mentioned elsewhere; 'pay for an electrician to look and give you a quote'? Um, find a different electrician/company! One does NOT pay for getting an initial estimate. Even if significant engineering is involved for changing/upgrading service there should still be no charge until you accept their proposal to do the work.

Hi! I think before you embark on the mining business, you have to do some feasibility study. Like for instance, how much money are you willing to shell out as an investment? With this question, you can now gauge the amount of space you can take in, how many miners you can employ, how many computers you can take in, and etc. Best of all, you will know as little as can be your possible operating costs. You need to be able to answer all these questions before you can focus on the electrical set up.

.

 Then derate the service by at least 20% (or add 25% to the consumption of each miner) for 24/7 usage.

 Given South Florida summers,  you want to be CONSERVATIVE on those estimates due to the heat.

 I'd be inclined to say "2 S9 = 20 amps on a 220 circuit" in a hot area like you're in.

You have now made a good decision to become a bitcoin miner, ... hope you succeed

You may want to consider the price of the electricity. Miners such up a ton of juice, and I imagine in south Florida, especially in the summer, you will need AC to keep the miners cool. Everybody will be using electricity, so summer mining may cost more than other seasons.

A lot of power companies also kick their rates up for 2-4 months during the summer, DUE to the load A/C puts on their systems.
