Working on these for sometime. Happy to finally have something to bring to market.

New 300KW mini unit, 90 new gen miners.

These are some beautiful mining containers, i really like them and i don't think i have seen anything that was better built than this, good job.

I guess it could be in hardware section of mining.

So some fast questions.

Where are you shipping from? USA, China

I like it and could want one.

we have three phase 208 but I think the feed panel is 800amps of 480.

shoot me a pm.

My location is New Jersey.

Thanks for the positive feedback guys. We are based in Toronto, Canada - but I ship to the US often.

They can run on 480v if you miner supports 277v, but we need to put a small transformer in for the fans, lights, and network switches.  Alternatively they can be 415/240, or run 208v PDUs.

I'll shoot you a DM with more info. Happy to answer any other questions anyone has.

I have to check with my notes 📝 as I know we have a three phase and we have 800 amps

I don’t remember if we are 480 into 208 or some other drop down

we generally get 217 to 229 in our panels. once we break down from the 480 or what ever it is.

Once I know your setup I can let you know the final price. 208v PDUs cost more than the standard 415/240 PDU that comes with it, but not a massive amount.

I tried responding to your DM, but I'm limited to one message per hour lol.

I can't escape you Scott. Good work all around.

I'm everywhere lol.... I can't figure out how to change my username on here though lol  I signed up for this many moons ago lol

It's fairly common in the USA to have 480 phase to phase, and 277 from one phase to a neutral. There's usually a stepdown transformer to provide some 120/208 but then again, many things CAN run off 277/480. In commercial buildings that is.

Incorrect.
In the US, 480V service is the start of what is usually called "heavy power" and usually only available to industrial areas and large commercial developments such as malls and office buildings. In large buildings it runs HVAC and is also distributed throughout the building to feed local 120/208V transformers that feed power to different areas of a building.

The only common use for the direct 277V phase-to-neutral is for overhead lighting fixtures designed to accept the high line. The 3-phase of course supplies large 3-phase loads. For all virtually all other '200V' devices, they usually top out at a maximum input of 240V and WILL quickly fail when fed anything over 250V.

we are a ware house built pre wwii
our concrete slab is six feet of poured concrete. the orginal use was building military gear for wwii.
we have many panels for power and
I checked we are 480 and we are 3 phase

we usually run at 219 to 229 on each and every phase.

however there are two really large transformers inside the ware house that may help the 480 turn into three phase 208/220

I know there are three legs labeled a,b,c and each 30amp feed has a,b or a,c or b,c gives us 219 to 229 pretty steady.

There is no 'may' about it: those *are* the 480/220v step down xmfrs.  :)

yeah I was  pretty sure just worded it carefully. As I am far from expert when it comes to high power setups.

we could run a lot more gear but the fud caused by covid-19 has set us back a bit.

going to meet with warehouse owner this weekend and talk a bit.

I would like to run a mini pod with all s19 pro  maybe a mix of t19.

Do you have a video or data on the sound coming from a fully stacked pod?

It will be pretty hard to estimate how loud a fully stacked pod is just by watching a video so an exact decibel figure would be much more useful, but rest assured that it is indeed loud as hell, 70 new gen miners mean 280*6000rpm fans(70*4 fans per miner), that alone is a ton of noise which can't be suppressed, and add to it a single 240k cfm or 4*60k cfm fans, the sound level will be sky-high.

I always say this but let me repeat it, if noise is an issue you shouldn't be thinking about mining on any large scale.

I think one box has a 15k cfm fan
I think you can join four boxes 📦 and go to 60k cfm

we have one 13.8 k cfm fan it is not crazy loud as it has a four or five foot width. it does not spin super fast .
so it is deeper pitch and not terrible.

but like you said 70 units with four small fans each will make tons of high pitched noise way over 85db.

Impressive work on these.

How weather resistant are they? Do you ship to Europe?
