Glad to hear it is getting installed. This is very exciting news!

Indeed it is.  I'm told they're rolling out the software for energy arbitrage this month, so the timing is good.  However, I've also been told that I cannot accept a tax credit as a result of enabling the energy arbitrage feature (wasn't given a clear reason why), so while it would be in my personal best interests to take the large tax credit instead of enabling the energy arbitrage, that doesn't seem like it's in the best interests of NastyMining or the most fun.  Since $$$ isn't my goal here and fun is, I'm officially forgoing the tax credit for the opportunity to play with the energy arbitrage features.  Cool

P.S. As a result of the heavy moderation of this thread due to all the 1-liner posts from newbies, I've disabled email alerts for this thread.  I'll check back on it every so often, but if you ask a question here and I don't respond within a reasonable time frame, feel free to shoot me a PM and bring your post to my attention.

The Powerwall 2 is installed and has passed QC inspection.  It may be several weeks before the city gives the OK to flip the switch to activate it, but I do have current access to the "brain" of the system.  It's a bit cloudy at the moment and I'm doing some laundry, but here's a cropped clip from the iOS App showing some Tesla goodness.

TESLA POWERWALL 2



I would like to say a special thank you to Gunthar, the creator of Gunbot.  His sponsorship of this project is greatly responsible for making advancements like this possible.

Bad news.  The Tesla Powerwall has failed the final inspection with the city.  This was due to them not using the same breaker panel box listed in the application.  They will need to resubmit an updated application and schedule another inspection before the unit can be switched on.  Hopefully this happens relatively quickly.

Sorry to hear that.  Undecided
The bureaucracy is sometimes very strict.

This is a very cool project and as an electrician and electrical engineer student I'm getting a huge pleasure watching this.  Cheesy

They decided it would be faster to install the breaker box in the application than to start the process over from square one and are expecting to have the issue resolved next week.

Good to know.  I hope this will get sorted out soon.   It would be nice to have the power wall functional as it has been installed for a while now.  Will this be enough stored power to run the miners all night without tapping into the grid?

Looks like this should get resolved on Friday (crossing fingers).

We can't generate enough power to even sustain the operation during the day right now.  Once the powerwall is installed I will be looking into further energy production measures.  Possibly installing something like this if I can get a sponsor on board.  I may also look into selling off the lower performing miners (D3) to reduce power consumption.  The powerwall can currently only sustain the operation for about an hour at night or two hours during the day.  Adding an additional powerwall would be fairly easy (just costs $), and perhaps with another powerwall and some more solar/wind energy, going truly off the grid for long amounts of time may become a reality.  The biggest advancement still ahead would be an immersion cooling tank for the miners.  I've read that can reduce energy consumption by up to 40%!  If we had such a system, along with the planned solar/wind upgrades and an addtional powerwall or two, we could be looking at a powerhouse operation unlikely to be matched by anyone without a massive investment.

Based on my knowledge on electrical engineering this doesn't make sense to me.

Have you read some study or testing about this? Any sources?

I just can't buy that he is basicly saying that
  • S5, air cooling - 660W per machine
  • S5, immersion cooling - 360W - same hash rate

It must be an measurement error or something else.

Other studies show that you do not get the power efficiency ratio better with immersion cooling.
It just makes it possible to run the device with higher performance settings vs. air cooling.

Here is a fellow Finn, Niko Punin from Bitfury:

Or other explanation for this is that S5 is actually surprisingly good with power efficiency when you use immersion cooling,
but I see that as very small chance.

40% is definitely a bit of a wild claim, which is why I worded my statement the way I did.  There is undoubtedly efficiency savings from operating at a lower temperature and not using fans, but I would guess somewhere in the 5%-20% range.  Besides efficiency savings, the larger benefit would be the ability to operate more equipment, as cooling is currently what is stifling growth (if you figure in air conditioning costs, 40% savings could even be a low estimate in the summer).

Yeah those numbers are much closer to the actual savings that could be achieved.

You really can't ignore the air conditioning aspect when it comes to savings.  I estimate that using immersion cooling would save ~$1,500 annually on air conditioning costs (~15% efficiency improvement).  Not to mention cutting down on the impact of running an air conditioner would be a benefit for this project.

Yeah agreed AC is a no-go in mining.

I'm not ignoring those savings, but I was focusing on the miner power efficiency comparison.

I think that all in all we are pretty much on the same wavelength about all this.

The Tesla Powerwall 2 has passed inspection and is currently charging with sunlight!

The only remaining hurdle is that the operational software for the Powerwall needs an update for me to be able to adjust the operating procedure to be beneficial for this project.  I'm told that will be happening in the next 3 weeks.

How do you cool the mineral oil though?
You have to change it every now and then once it reaches a certain temperature?

The system I'm looking at uses a water line to cool the oil in a heat transfer unit.

Would you be running a cold water line coil through the oil tank on it's way to say your hot water tank? Or I guess more likely through an oil reservoir tank that cycles through the individual cooling tanks?

I just started following the thread and have some back reading to do but I love the idea of using all the energy and reducing it wherever you can.
