Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

[tharani]

Solar panel can be used as long as it can supply you steady 1600W range to be plenty for 1 S9.
but steady power feed is needed to keep the miner up and running.

Can anybody tell me if the Antminer S9 can run on solar power . .

http://www.tatapowersolar.com/#

i can install and let my miner run on it.

i can ask the company to let me know how many hours of power supply it will provide.

That way i can get free electricity and don't have to worry about the power costs.

Ok i will enquire it with the company , to ask if i can get steady power supply in here , but it seems the best option since i cannot get free electricity.

Here is the calculator result for 2000 sq feet area.

Result - save upto 1,800* units per month.

I can make it directly connect to the miner so that power is supplied only to the miner.

Not directly if you want 24 hour power

1)Panels to inverter to psu to miner.  needs a grid tie in to skip batteries

2) Panels to charger to battery to inverter to psu to miner.

3) Panels to  dc voltage regulator to  miner is most direct but a bad idea as you could get dc flux up and down with clouds or rain.

this is a link to the setup I am a partner in.

ok then thanks i will research a bit more and also ask the company then.

can look up a manual or you people can help me set it up will take a few months.

Antminer S9 mines on DC right , ongrid solar power supply units supply power in AC so i will need an inverter.

Here's a link for ongrid system's.

Offgrid max is 1200 w What is the difference between ongrid and offgrid btw.??

Thanks a lot then.

for those of you wandering if this is the auto tune version.  This pic seems to be a stock 14TH model.  so it will be set to hash at 650M frequency by the firmware.

Has anyone tried the firmware from 11-19? I'm giving it a shot on one machine right now. Curious how it is working for others?

Fan speed is much better handled for me - slight variations in speed, gently ramped, instead of the bang-bang controller in the previous autotune FWs.

Seeing much lower reported temps (~10C lower) but I haven't dug into whether that is just a cosmetic change or a change in setpoint for target temp.

Hashrate is good - 13.904avg over 3025 hours on a batch 1 set to 650MHz (theoretical speed 14.004):

Nice of you to jump in, and still be following the thread.
but please, can we discuss the elephant in the room? wtf is with these fans
They idle so low one minute, and the next minute my neighbors can hear them.
I have no issue with noisy miners, but this seems like it's just unrequired noise.
One minute they blast at 110% the next they are cruising at 25%. than boom back up again.
If they idled Higher, at 60% maybe? they would need to spike as often, and this would help with the noise greatly.

The ROI on these with cheap power is sometimes mind boggeling.
You will never ROI with solar, so only do this for your home, NOT for mining.

I am not looking for roi if i take up form filling  for now i am gonna take data entry first and then practice and take up form filling in a few months, i can buy the Antminer S9 in 2-3 months after i take up form filling job.

It pays around 730 dollars a month.

Can check it's ok even it if mines 0.01 btc a day.

Can somebody say the exact value it will mine per day,  if ran for 12 hours and 24 hours respectively.

Should let it take a rest inbetween 12 - 24 hours continous mining will get repair it off soon.

the "elephant" for home-miners is the noise, and especially the strong modulation of the fans yes, and yes it is annoying. Before setting the miners in the actual racks where the noise is no problem, we always test them in the office for a while to make sure they run fine. Right now my ears would be ringing if I wouldnt be using earplugs. and they are still annoying.

Nice of you to jump in, and still be following the thread.
but please, can we discuss the elephant in the room? wtf is with these fans

I have no issue with noisy miners, but this seems like it's just unrequired noise.
One minute they blast at 110% the next they are cruising at 25%. than boom back up again.
If they idled Higher, at 60% maybe? they would need to spike as often, and this would help with the noise greatly.

If you read the thread, people even gave a solution to have them running more constantly. I.e. the followoing

there is a way to controll the fan speed. im sure the firmware can too they just dont want to allow that but the way im talking about requires an external device that connects to the pwm wire that sends the signal needed to spin the fan up and or down. i got a bunch of them a while ago to control the fan speed on delta fans that have 4 wires (12v, gnd, tac, pwm) and they work great. since pwm fans need the 12v power to be steady all that is needed is to hook the pwn wire from the fan connector and connect it to the little module. the module isnt made to handle tons of power through it that delta type fans use but since the 12v and gnd are still on the main controller that wont be an issue. i tested it with the pre autotune s9's and was hoping to use it with s7's when it got colder but it turns out it wasnt that loud so it wasnt needed. i can test it with the auto tune firmware s9's too but im pretty sure it will work just the same. you turn the pot on the device to raise and lower the fan speed. one would be needed for each fan and maybe 1 can run both fans im not sure. i tested it on 1 fan at a time though.

http://www.ebay.com/itm/Mini-Fan-Controller-Use-on-4pin-PWM-Fans-Only-/251310564631?hash=item3a8346e517%3Ag%3AD8QAAOxyPc5R8pd&nma=true&si=xc7ix74cLY6XzIvXO35N657fd3U%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557

that link is super old but thats the speed controller i used with delta server fans. it only shows a pic of the top side with the pot but the underside has the components that control the fan speed. they have other versions similar with a plastic shroud over it and should work the same way. i went with these because it was a simple design that attached to the fan itself instead of having a box hanging there. im not responsible for any wrong hookups though and even though its pretty simple to do make sure your removing and hooking up the right pin....

But the cause for the so-called "elephant" is a much bigger problem with the auto-tune S9s. And that is the extremely high range of frequency distribution over the 3 cards/boards/blades in a single S9, at least for the B22-11TH/s models we have. This in turn leads to miners breaking down rather soon (in my case one miner was bye bye after less than 24h), leading to repair/delivery costs (even in this case) and downtime of the miner. So, honestly, what is worse, a strong modulation of the fan speed ==> noise levels, or that Bitmain is selling faulty products to the its customers, which break down sooner than later.

There many possible causes for the bad frequency distribution, be it the faulty automatic-tuning firmware of Bitmain of the cards which leads to this distribution, or be it the greediness to use underperforming chips on the boards. Nonetheless, it is a problem introduced by Bitmain by selling faulty machines (be it firmware or hardware) to the customers (be it on purpose or by accident).

ya no one seems to read my posts very much lol. i agree the auto tune feature isnt much of a feature. it runs boards too hard and i personally would want to control the speed. idc so much about raising it but i would at least like the aility to lower the speed but with the new firmware your unable to. my post was just to give some sort of solution to those that wanted to solve 1 of the 2 issues which is fan speed control. if it helps folks great if it doesnt great lol. at least this way they can try to get a handle on the high temps when running these auto tune miners.

I read your post, just didn't fully understand what you were getting at, It also seems like it may not be the best option, If we set them at one point and it at some point needs more, no way to get that.
A software solution that won't let them go lower then a certain speed, but still ramp up if needed would be ideal.
But I will look into those controllers.
Did they do a fine job of tricking the s9 into thinking it still had control?
As I understand it, the thing shuts down if it thinks the fans stopped running.

takagari - This is what I posted about re: the 19 Nov firmware. For me, this firmware stops the fan cycling and replaces it with much subtler changes in speed. Higher average speed over all, but barely perceptable speed changes.

It's a big improvement on my S9, which is a Batch 1 / 14TH/s as BitmainWarranty suggested.

[wolfen]

Looks like it is the hashboard that is the autotune piece. I received a replacement board and installed it on an older s9 12.93 that had the autotune software
already installed and the new board autotuned but the others did not. Thought I was losing it.
Nov 19 firmware looks good.

[takagari]

Okay I'll google for the Nov 19th firmware, unless someone has a link?

It balances the noise out a bit? that's great.

It amazes me how I have to look at it to see if it's even running one minute, and the next minute yell to hear myself lol

As I understand it, the thing shuts down if it thinks the fans stopped running.

the 4th wire on the fan connector is the pwm wire. this is the wire the fan uses to control the fan speed. the adapter i sent allows you to control the fan speed of pwm fans. it cant handle high wattage loads thats why you would unhook the 4th wire (blue) from the fan connector and connect it to the 4th pin on thespeed controller i linked in my post. used a flathead screwdriver you can use the pot on the board to raise and lower the fan speed. i thought this was clear but wossry if this still isnt clear enough for you.

yes this method is not ideal and i even said a software method would be best but this is a solution. its to run the fans at a constant speed. you dont use this method to run them at the lowest posible speeds...this is to raise them up so the temps stay steady and dont run into the hundreds like the stock fan settings do. thats all this is good for.

[takagari]

Oh so you just tie in the one wire. Is it simply a pot? Or is there more involved in that adjustment? I can't find the one you purchased any longer, but I'm still looking.
Thanks

[NotFuzzyWarm]

The PWM signal is not analog (from a pot). It is digital Pulse Width Modulated signal, I think around 1kHz, that drives a switching circuit inside of the fan that handles the power side of the equation. The on-time vs off-time determines fans speed. Just to confuse the issues, there are 2 different schemes used... Most common one is no signal (always Lo) puts the fan at full speed in case the signal wire opens. Also seen is the reverse - no signal means slowest but usually not zero speed.

Query: What does the fan do with the blue wire disconnected? Full speed or slow?

At least, I am not sure that I got it.
It does have -all- marking, but what is autofreq-user?
I got two different 11.85th (summer) and 11th (fall) batches.
Are both of them autofreq or only later 11th?
