What does the upper value mean, input voltage? If its 228v it should be safe for the S15 no? China uses 230v @50hz, like Europe.

at that shot  we were at 228  but it fluxes  as high as 243 as low as 220.

that transformer  attempts to flatten output to 220.  My testing shows it does that  pretty much spot on.

It is rated to do 22.7 amps  24/7/365  that is 22.7 x 220 = 4994  hence the 5000va rating

but  the input  power cord is 14 gauge  no way a 14 gauge  cable is going to handle 22.7 amps 24/7/365

I would trust it at 10-12 amps:

  so 10 x 220 = 2200 watts  
and 12 x 220 = 2640 watts

we are doing  about 1580 watts with it as I type.

the warehouse owner has a model in mind he is going to do that.

Next posts will show  new fan and  cleaned up wiring.

I will be doing some awesomeminer work with this setup.  For the next week or two.

Looks great philip. I think you said you can only run one s15 with transformer in the other thread ? Did you have an exhaust fan in mind already?

@ yankees  owner of warehouse said it got  warm  and now realizes that we will need at least 1 fan with a  good vent to the outdoors.

we are looking to see if we can install a 2 speed 10000cfm fan

Phil  NJ got warm  on Monday and on Tues  62f  then 67f

Did warehouse hold under 80f  or did it get too warm?

Got back from the build out.
Need to figure out how to download photos from my phone.

We added an s15
installed awesome miner

we are up to

 535th btc
    6.6gh ltc had to downclock gear.

we will need to add an external fan  as the 95000 square foot warehouse did get too warm when NJ weather reached 67f on tues.

actual solar install  will be  months from now.  Buysolar will apply to power company  to see what they want to allow the 300k-watt install

We are pulling about 60kwatts  which  is higher then the install will do when complete  say 300/7 = 42 kwatts an hour 24/7/365


but the 60kwatts  raises average quicker.

We will be looking for another m10  on thurs the 7th

and more m10's down the road.

per hour  24/7 on average.   or 24 x 42 = 1000 kwatts a day

ok yea that is much better. I am possibly selling 5 of my s9's and if that sale goes thru, I will be buying an S15 and an s11 or maybe 3 s11's not decided yet.

yes - the average is lower now - more like 30 to 35 kwh  and wait, your 1000 panels is only 42 kw per day? or do you mean per hour?

per hour  24/7 on average.   or 24 x 42 = 1000 kwatts a day

I wish my solar was more effective - 36 panels and only 40 to 45 kwh per day generated - it was supposed to be generating 60 to 70 per their damn sales pitch.

It is always hard to tell if they (installers) are any good.  So many reasons it could be that low.  but they mostly boil down to they lied or they installed it wrong.

Also it is the winter you will be much lower numbers now then May,June,July  If you are in northern hemisphere.

In NJ  we do 9 hours of light in winter and 15 hours of light in summer

average of 12 is not what you use.  as those 12 hours come to 5-6 hours of full sunshine  So we base NJ numbers at 5 hours a day

They could be using the high number for estimate 6 hours a day.

They could have mismatch inverter
They could have a bad wire job.

this build will be 1000 300 watt panels = 300,000watt or 300kwatt setup  but that is a peak number.  We divide the 300 by 7 to get 42 kwatt we round to 40kwatt this is very conservative.

The yearly average should be 40kwatt 24/7/365  A lot of installer would bs and say the system will generate 50kwatt 24/7/365  which is really possible but in practice it will be 39-45 24/7/365

we prefer to go low on estimates since customers are happy to do a little more than promised.

very nice phil! I am jealous - I need to get one of these put on my second lot lol

I can not wait till we get the solar up  in late spring.

Looks great, I actually love use of more natural cooling. Cross drafts, with overhangs in a shotgun form or simply a "copula" outlets  in a larger facility.

Great project philip.

Warehouse owner is liking what he sees at the moment.

He wants to talk about a second warehouse next week.

This warehouse was so perfect for what we did I hope the next warehouse is close to the same quality and setup.

If it is we will be over 1ph by the summer.  with ½ solar

by end of year entire 1ph would be solar.

Fingers are crossed this continues this well.

Sure beats a lot of fancy systems, hot/cold air alleys, etc. and the warehouse get free heating.

Yeah  we will need to tweak it , but we are doing 50kwatts  which is about 200000 btu 24/7/365.

When it warms we will add an outdoor vent to take air out.

This place is  about the size of a walmart  so it can use lots of heat.

As we  slowly upgrade to solar we will upgrade to all m10's or s15's

the solar  will give 40kwatt 24/7/365 on average  for free power.  Since the roof will have more then 300kwatts of panels.

I am excited this could be the first of 4-6 similar projects.

Great farm Phil.

I don't understand the air flow, care to elaborate on it?

Oh and what plugs are you using for the PDUs?

L6-30p

air flow is a work in progress.

the warehouse is massive and not heated.  Trucks open and close the large garage door the ceiling is at least 30 feet tall.

at the moment we are using two high speed fans to draw in cold air  and letting hot air simply rise.



you can see one of the two fans on left side of room
