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?

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.

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
