Topic: New buildout with buysolar has entered stage 2. - page 6. (Read 4275 times)

that is full cost  

in my state winter rate is

9.1 for power
3.9 for delivery
13.0 total

summer is

12.8 for power
3.9 for delivery
16.7 total

if I adjust for heat benefits in winter and lower the 13 cents I mention it
if I adjust for more cooling costs in summer and raise the 16.7 I mention it.

we have 3 shared locations  for the solar

Clifton NJ
Howell NJ buysolar's office and home

I have my garage. for me mostly testing and setting gear up

my garage setup is 13 cents in winter and can drop heating bill so real cost is 13-2 say 11 cents

my garage setup is 16.7 cents in summer and can raise cooling bill so real cost is  16.7 + 1.3 = 18 cents

most of the time  I don't put in the heating benefits or cooling negatives

I go with 13.0  winter and 16.7 summer.

This winter I have not mined much in house/garage as it is all power company and most everything mines at a loss  at 13 cent power.

Many winters the garage/house was pulling 7kwatts 24/7/365
this winter  2kwatts more or less mostly from prepping gear to go to the bigger Clifton NJ build.

Buysolar also mines less at his home + office setup  as once he goes over 14kwatts he begins the 13 cent cost.

IN Clifton  we are building the foundation (power footprint) so to speak for the solar 300watt x 1000 panel install

the ware house has a 2 acre roof  and 1000 panel max fits.

I am always curious when people quote rates.  Is this the bottom line electricity bill number divided by the # of kWh you used, or is this the rate you pay on your electricity plan?

I ask because the 2 numbers can be drastically different.  For example, right now I'm on a plan that has high service charges, but low electrical rates.  I'm paying around $0.05/kWh on electrical usage, but the bottom line on my bill is closer to $0.10/kWh after fees, and lowers with the more electricity I use.

home depot sells it

I like using it with this fire/short blanket.

here are some videos using it

if you look you can see both the silver/sound proofing and the fire blankets

Can you tell us the name of the material? Is it a thermal/sound insulation material?

ouch, I now love my 5 cent power more after hearing that 13 cent number. lol

It is 1c and the room is okay.

At 60f and or 18c   It gets warm.

NJ weather means we have 2 months before we go above 60f a lot.

We will have an external fan sooner then that.

A two speed 5000cfm to 10000cfm with a thermastat.

36 inch .  Since we have about 50 units with 200 cfm fans.  I am pretty sure the two speed fan will do the job.

Keeping space cool won’t be an issue.

That mining room has :

208volt feed
240volt feed
480volt feed

We could pull 500kwatts from the feeds.

But  power cost is 13 cents.

The first 40kwatts is solar and next to free.

After that 13 cents.

Once setup we will have extra gear just in case of a run up in coin price
And tap into the high cost power.

Understandable that he didn't want to put any holes in the wall. I hadn't realized it was probably built as an existing electrical room originally.

Yeah I'm still stuck in winter mode and heat conservation  - hard mindset to break with a steady low of -30C lately.

I was wondering what does the overall build have for air intake besides the warehouse doors opening and closing? Probably wouldn't take much to maintain ambient if you have enough exhausts, likely even get away with no fans and natural circulation if you do use the high hats for removal.

I may get a vent to outside air source for intake.

I am pretty sure we won’t need it.

The room is 8 by 10 by 20.

No ceiling.

The warehouse is 200 by 450 by 30.

I am pretty sure that once the out take fan above the fire exit door is installed it will move a lot of air right out the building.

The roof also has three large high hats to pull air out.

The limit to this build is not heat
The limit to this build is not power available.
The limit is the roof size allows us to build 300 x 1000 panels = 300 kwatts or about 40kwatts 24/7/365

For “free “ power.

I quote free as it is reduced cost power due to USA and NJ rebates tax credits etc.

I will drive up this week and pull some s-7s put in some L3+

Hope to be at 520th btc. 8gh ltc by thurs.

I wish I could still get those cheaper m10s
At least I got 4 of them.

Would an air vent in the door be acceptable to the owner? It would seem less invasive and easy to replace in the future if needed.

this month I will be adding some sound deadening as well - can hear my miners from the road lol - but it should also help with insulation against the summer heat.

Just added more sound proofing on the floor Some rubber mats over  the same sound deadening material that is on the walls.

Drops sound down quite a bit.

Its a regulador de voltaje, that's what we call them here...

Something like this:



Regulador Sola Basic Xellence 3000,3kva,bifasico,220v,2 Años
$ 6,990

I think they call them voltage stabilizer in Europe.

Yes, input can be a varying range (169V ~ 271V), and the output is a fixed (220v). They usually do come with peak protection and timer delay if power goes out of range. The smaller 120v cousins are very common for PC use here (and in many parts they are a must have if you don't want to be replacing PSUs every 3 months).

yeah  But the owner does not want to cut that wall.

he is willing to put a fan to vent outside which will solve the issue for the summer.  today is cold 25f  so no issue.

And since build has both:

 btc 530 th
 ltc  6.6  gh

the price jump  yesterday  for both coins was very nice.

That build out looks nice. Super cool that the warehouse owner has another location for a continued expansion.

I only noticed the 1 fan in the picture showing the red door to the warehouse. Had you considered using floor level intakes to bring the air into the space. It would help create a nice steady in from the bottom out from the top air circulation. I'm not sure what the quality of floor level air is there, but I imagine it wouldn't be much worse than what's floating by the fan. You would also be grabbing what would likely be the coolest air in the warehouse, bonus if it's a nice solid concrete slab.

they have a 208 to 220 boost

which would boost 204 to 216

Mexico, and I meant as low as 204.

Thanks for the links.

stable clean power is a luxury in many parts of the world.

Are you USA located?

larsonelectronics has a lot of good gear.

No they are not the same. Strictly speaking a 'protection transformer' simply provides line isolation and a Farady shield between the primary and secondary windings to reduce the impact of noise and spikes as well as probably some other suppression components as well.

A stabilizer aka regulator actively adjusts the output voltage to keep it within a specific output range. Many/most will have suppression bits as well but like the one Phil has, the line-in and line-out are NOT isolated from each other.

You have the transformer on just a single S15 miner Phil?

And is this "Protection Transformer" the same as a "Voltage Stabilizer"?

I have 2 B1+ that keep going off and Tech support said to buy a voltage stabilizer, I do get 214-229 volts.

Also I think it will be too much of an investment if I can even find one to handle the 5000 watts from both miners.

Yea, I have my fan, I just need to install it. but kinda have not gotten to it because the cool weather. but it hit 80 today so I may need to do it soon.
