Great in theory, hard in practice due to the wire gauges involved in carrying the current to your miner.  Math:  13.5Th at 0.098w/GH = 1323 watts at 12V = 110.25 amps.  Would you really be willing to run 00 gauge wire to each miner and then break that down to (9) 6-pin connectors?

If you mine with solar power on batteries you will almost always come out worse off than if you just bought the power at residential retail rates. You have to factor in wear and tear on the batteries - which by itself can be greater than just buying the electricity. On another note - if mining on solar power skip the inverters and power supplys and use direct current DC converters.

That's a normal number.  You're fine.


MINE ON WITH KANO-SAN!

Please help, why so many are rejected? and what can be done to fix it? (screenshot) http://prntscr.com/j0b3rd

Getting excited. Received a notification that my S9 is coming tomorrow rather than next week.

My outlet arrives today so I'll be swapping out a breaker, running a line, and should have everything set up and ready to go as soon as it arrives.

Also chuckled when you said "a warehouse with a roof big enough".   Basic solar math, presuming you want to run on 13.5TH S9, with a real world consumption of around 1450 watts:

* (1) typical panel, lets say a 130W one, will produce about 4 hours of power a day at 80% of its rated rate (since the rated rate is optimal during noon soon in the tropics):  130*0.8*4=416 watts per panel per day
* Each miner therefore requires about 3.5 panels
* 1 megawatts of power = (690) 1450W miners = 2,145 panels at about a square meter each, so call it 21,450 square feet of roof space over a data center that doesn't need to be over 2000 square feet in size, likely larger.

But wait...  Nobody is going it invest that type of money to run miners for 4 hours a day, so lets add batteries and enough panels to run for a full 24 hours:  80% efficient charging batteries = 2145*6/0.8 = 16,100 panels.  So about $2M in panels.  Batteries to carry say, 3 days of clouds, will match that cost.  So now your at $4M.  Oh, but wait again... we only have enough panels to keep ourself running for 24 hours and now, after a cloudy day or three, we need to run AND charge those batteries.  Better double the array size (now $4M and 32,200 panels).  Plus battery chargers, inverters, etc.  Add at least another $2M.  

So, we have $6M in solar infrustructure to run 690 miner at something like $1300 each current pricing (sorry, Bitmain doesn't have 13.5's listed right now, which this math is based on); eg. ~$900K in miners.
At $0.10/kwh, and 1MW of required current, each hour cost $100.  So in about 7 years you will break even.  Except that your batteries will likely have been replaced once in that timeframe and likely be coming due for a second round, at $2M  a pop.  Good news, electronics are likely good for 10-15 years.

Oh, and since we now have 32,200 panels in our little setup, your going to need about 320,000 square feet of south facing roof.  That just a bit over 7 acres ON THE SOUTH SIDE.  So a 640,000 square foot warehouse of which you will be using around 2000 square feet.  Or perhaps you could find a 6000 square foot building and provide about 1% of your power for a mere $60,000 - but why bother.

Granted, you could grid tie, and eliminate the batteries and half the electronics, but then you need to deal with paying retail power rates and likely being credited wholesale power rates.   Not aware of many NEW grid tied solar contracts that allow for reversible meters like they use too.  They electric companies have wised up and paid off the right politicians to protect their turf.

I'm in the east coast of the US.  Is this the best setup?

primary: stratum+tcp://nya.kano.is:3333
2nd stratum+tcp://stratum.kano.is:3333

That's your miners fault or your networks fault ...
NYA hasn't had a fail over for a while and pool2 doesn't affect pool1.

Do I need a different setup for failover:   Pool 1: nya.kano.is
                                                       Pool 2: stratum.kano.is

I checked to make sure I stayed on Kano and it rolled to my third pool (no likey).....

Thanks

Oh also - I was about to post about a failover when I got sidetracked on the posts above

The LA half of the stratum.kano.is node did a double failover at 03:22 UTC (the 2nd time 4 minutes later)

So half the miners on stratum.kano.is will have failed over to their 2nd pool for about 10 minutes at 03:22
Hopefully you all have another *.kano.is node as the 2nd pool so you failed over to here also!

Mine On!

I gave away two 420s.

I could be coerced into giving one more of those away and a 220. I’m holding the last 420 for personal use.

The stipulation like the others I gave it to is id really like to see a receipt so I know they’re not getting sold. I trust just about everyone on this forum until they give me a reason not to.

PM me your bitmain email. I’m going to sleep now but when I wake I’ll ship a 420 and up to two 220s to you.

EDIT: I'm embarrassed.....but I feel it's necessary to bow my head in front of the tribunal and report my mistake. I prematurely completed the checkout to see how easy it was to apply the coupon to finish the order for an S9. Well, I'm still waiting on the rest of my BCH to be deposited from Coinbase and the goddamn order expired. It only gives you 1 hour to complete payment. When it does this, it DOES NOT GIVE YOU BACK THE COUPON!! 
I reached out to BITMAIN (as if that is really going to do anything) and explained, so we'll see if they will have any pity, but doubtful.

Took me 3 efforts to process my payment and I did it over OKEX and still took ages even though I think now they are across the street of each other (bitmain, okex). As I have heard bitmain was expelled from china mainland and now in Hong Kong. It also says expired but when they get coins they change it to paid. So you might need some patients  there.

They will give you the coupon back to use once you explain what happened, at least they did for me... but you will just have to reorder once they put it back into your account...

Not real user friendly when they make you have BCH (which I dont keep) or a wire transfer (which is also a hassle)  ...

I wonder why they dont take BTC?

They used to but jiggly with BTC "expiring" thingy.

Best of luck! 

Mine on with Kano!!
