Newer homes  built in the US are more efficient and don't require amperage like the in the past. That's why you see 100 AMP service for a normal size 3 bedroom 2 bath house now. My house was built in the year 2000, which is considered new in the housing world and came with 100amp service. If the house was 20 years old, I bet it would have 200-300 amp panel in the basement.

FWIW I have never seen a 300A panel in a home.  200A is the highest I've come across and that's usually in McMansions.  Standard is 100A, and I've seen much, much older homes at 60A.

2000 watts(approxomate Neptune draw) / 110v = 18 amps per Neptune. (USA)
5 Neptunes would Max-out 100 amp service right there

100 amp service means 100 amps at 240v, so that would give 200 amps at 110v.  

I have 200 amp service and don't even have 220, I installed it myself under the direction of professional Electrical contractors, and the county inspector. I believe him.

Volts x amps = watts, Period. You can re-arrange that any way you like.
Watts / amps = Volts
Watts / Volts = amps

But if you really want to save $ on electric, you MUST get a Power factor correction Capacitor
it will save you 20-25% off the top if you are seriously mining
(The scam is electric companies actually charge by the volt-amp, and not by Kilowatt-hours) This corrects that.

Some of us installed 200 amp months ago.... Then, lightning struck... literally

That would be 100 amp service at 240V. You have two 120V phases coming into your house each at 100A. Five Neptunes is a lot; but, you make sure your running 3 on one phase and two on the other.

100A x 240V = 24000W

or

100A x 120V + 100A x120V = 24000W

Same power...two phases.

Yes, I agree... also if you use 220v to supply your Neptune, the amps will be 50% less, while the Wattage remains unchanged.

[butjust41day]

Well that I agree with.

[WastedLTC]

Neptune's arrived about five minutes ago - Batch#1 order paid for on the 26th November.

I'll let you guys know how they perform! Even though they are late (very late) I am a bit excited :-D



If it is preconfigured with any pool details I will let everyone know.

Coins per 24h at these conditions 0.1121 BTC
How much did you spend on it

In total 13 BTC at $900 per BTC (inc. shipping / taxes).

I've already bought back the 13 BTC at $500, I'm expecting the miner to ROI around 6 months on its own BTC investment but I also enjoy mining and it opens up opportunities for getting some returns on alt's from time to time.

Sorry but you wont make a roi in 6 months, the next difficulty jump is 13 to 17 so how do you work out 6 months to return your money?

agreed...but...
it's already nearly 30% with 4 and 1/2 days to go....     how'd you get 13 to 17?

https://bitcoinwisdom.com/bitcoin/difficulty

clearly says 28.8

Estimated Next Difficulty:   17,351,720,663 (+28.89%)

the 28.89 is the change from 13 to 17 is how much in percentage

no, 28.89 means the estimated next diffchange is upping by at least 28.9%, period....
soon to be higher
I have no clue where you are calculating this 13-17%?

OMG..  12 responses about 13-17!    Take a step back.  Look.   Seriously.  LOOK.    13,xxx,xxx,xxx  - 17,xxx,xxx,xxx.     There u go.   Still have no idea where the 13-17 came from?

uhh, no.. you can't actually arrange them anyway you want. Only the first and second of your equations are valid, the third should be ( Watts / Volts = Amps )

Do you have data for your installation that shows you are getting a benefit from a PFC?

Anyone want to buy a Neptune? https://bitcointalk.org/index.php?topic=664368.0

I don't believe you.

Volts x amps = watts, Period. You can re-arrange that any way you like.
Watts / amps = Volts
Watts / Volts = amps

That's only for DC and instantaneous AC power.  The proper way to calculate average AC Power is via

P_avg=V*I*cos(x)     cos(x) is the P.F.

PS: "Volts / watts = amps" is wrong.

You only need P.F. correction if you live in a area with shitty service.

or

100A x 120V + 100A x120V = 24000W

Same power...two phases.

^^^^This. With a modest ~2kw in equipment right now, my house is already above 10kw/h part of the day due to 100oF outside.
I started thinking about solar panels, but they are too darn expensive, like 15K for 5kw worth.
In Texas mining looks more and more like a winter "sport".

Yes but your pfc is fine already

Sorry for the off topic but when I restarted my October Saturn it just keeps rebooting after 5s being responsive to Ping's ... at the same time it resets the blue light flashes very quickly.

I found that If disconnect one of the asic board from the board the miner runs well with the remaining one. ... I already tried to connect the "bad" asic to other connectors on the controller board but the same thing happens. ...

Is there any logs that I could look to see what is going on?
Does anyone saw this behavior before? The miner was running for ~25 days 24x7 without any issue but now this happened......
Does it mean the board died?

thx!

[dogie]

If anyone wants to fire a unit my way to do a teardown setup guide then let me know.

what firmware are you running/ how many ports do you have on the controller board

[helmax]

anyone receive refund in last 2 weeks? pufff

I have 6 ports on the controller board and it is running firmware 1.01
Somehow, after rebooting the controller many times and factory reset the settings with the asics .. and the restoring one asic board per time is now working .... no idea what happened or what was the problem...

thx!

I missed the part including the begging. I can't take 100mp+ chip photos without a unit - I'm not magic.

I think you should demote their manufacturer trustworthiness on account they didn't send you one. D-
