You are correct, it’s undersize.  But in economic terms, the grid is a much cheaper and bigger battery for normal everyday household consumption given current feed in tariffs.  

The battery is more about energy security.  Keep in mind most solar will be cut off when the grid goes down. People won’t be able to generate at all because the utility shuts down their solar remotely to stop them exporting.   The Tesla has a gateway to allow you to generate behind the battery.

Ok, so you're grid-tied with the ability to run your own power island if things go down off the batteries. My system is tied into a Sunny Boy 1800 for the grid which can be manually switched into a MPPT converter that can feed the battery bank in the event things go odd. Manual, but works. The batteries are in my work shed, which has about 320 watts of solar directly connected to it to keep the shed running and the batteries peaked.

I have thought about getting a Sunny Island or a Trace SW4024 so I can automatically switch between grid and solar, but another option would be to just break down and put the Matrix in the house and wire it up to a subpanel that runs the fridge and other stuff. I'll think about that, but a 700 watt inverter is enough to run the critical stuff including the microwave.

Solar panels *are* cheap these days, I bought mine at about $2 a watt used for the single crystal ones. Modern polycrystaline are a bit less efficient (take up more space and are *heavier*) but that's not too big of a deal. Will think about it.

This Covid-19 shit is starting to become a pandemic.

Absolutely surreal watching a game of Plague Inc. play out in real-time.

I'm starting to get the fear. Supposed to be traveling to Amsterdam, and Ireland in April.
For me it's like seeing "On the Beach" play out in real time. Yep, Oregon just went dark, party on!

Not sure where you live but we can get by on 14.5kw/h per day including two fridges, security systems etc.  

We run a 10kw system and it would be a rare day we get less than 15 kWh out of it, seeing as that is 1.5 hours at full load.  30 - 40 kw is more typical, peaking out around 60kw.

That is *very* good data to have, thank you. So on an average day you get about 4 solar hours of light, with a peak of 6 solar hours of light. That matches my observed values here with a much smaller system (~1kw) on a grid-tie/battery reserve.

I've noticed the fridges are the big power pullers (aside from AC, which in a disaster I am not running) not because they pull a lot of juice but because they pretty much always pull it. I should put a Kill-a-watt on the fridge again and see just how much power it pulls in a day, in fact I think I'll do that after measuring the idle current of Antminers (for another thread).

How big is your battery array? Mine currently is 200ah*24v or 4.8kw total. My solar array is about 1.2kw total (single crystal panels so pretty efficient) and my inverter right now is a 700 watt UPS converted to run on external batteries with a Matrix/5000 that can be used if I needed a really high drain load.

If I'm running my house in emergency mode it's about 4kw a day of power used. Which is on the edge for my system: Given I can only generate about 4kw of power a day with the panels I can run for a day with no solar power and even then it would be difficult for me to "catch up" and charge the batteries to 100% with solar alone.

My secret weapon for that is the car: A 1kw 12v battery inverter attached to a car can charge the batteries to full in a couple of hours. Having a hybrid in this case is *really* cool, as you can charge off the hybrid battery and the engine only has to fire up to charge the hybrid pack (which it can do quickly and more efficiently than running 100% just to spin the alternator). A bonus is you have a 10-20 gallon rolling fuel tank that you can also drive (at 40mpg) somewhere to tank up on fuel if needed.

So as long as civilization doesn't completely puke I'm ok. Really. Interesting. Stuff.

the lithiums have made impressive strides in energy density, outpacing your Trojans by a fair bit

that said, and I am quite aware of the dangers inherent in H2SO4, if I had one of those power walls it would be installed in an airtight bunker some distance from the dwelling...

when lithium decides to do the bad, it is really bad
True. For a house system weight and energy density aren't as big a problem as in a car (where you have to like move it). So L16 or T105 batteries can get you a lot of power for a reasonable price without the major fire problem of lithiums.

As for hydrogen I've never seen issues with lead, however I guy I knew did blow the bed off his battery powered truck with flooded NiCD batteries. Those last forever but really can gas hydrogen on charge. Oh well.

100ah AGM batteries are quite nice as well but a bit more pricey per AH. Any way you go, you need to figure out how much power you need per day, then build your solar panels to put that much power back in 1/2 day (factoring in cloudy days) with a battery capacity of at least 3-4 times your load for rainy days and the like. Thus if you want to run the fridge (200 watts*24=4.8kw) some lights (about 1kw a day) and a toaster (1,500 watts for an hour a day) you're at 7kw. Thus a 28kw battery pack and 14kw of solar will do it. Assuming 5 hours of sun per day (and you factored in the 2x oversize for solar) and you're talking a ~2kw array and if the batteries are 48v then a 500ah battery pack or 16 T105's.

Takes more power than you think.

Also remember redundancy can be expensive: When the power goes out you don't need to have a generator big enough to run your house for a month. What you need is enough power for the fridge, a lamp (really nice when it gets dark), the fans for your wood stove (in winter), cell phone charging (surprisingly little), a weber grill, and a coffee machine (because waiting in line for coffee sucks). I've done this for a week, it's really not that big of a deal and having cold beer, a light at night, and coffee in the morning goes a long way towards feeling civilized and appropriately smug at those without.

So.... Keep things in perspective. Try not to be part of the mass migration herd, either be the first one out (tricky to time) or wait a week till things settle down.

Or solar + a Tesla battery and pretty much run your household as normal

Even a Tesla battery has a limit, and to be honest a rack of T015's would work as well. The trick is how much you suck down and how quickly your panel array can reload.

In which case Bitcoin will not go up. Fiat will simply go down.

In other news, watch out: Latest Mozilla update wants to route your DNS queries through cloudflare. Which since it's an internet provider means the Govt will be able to see all of your queries without a warrant.

(Run your own DNS servers ffs)

Doesn't Mozilla obey to your OS network settings?
Used to, but apparently there is a new "feature" where DNS lookups are passed to the "cloud" rather than going through your local resolver.

Meantime it's fun to watch the stock markets implode. I wonder if Europe will do better/recover quicker as they are somewhat more intelligent than the current US leadership.

1,000 point stock market drop is a yawn when you have been HODLing bitcoin. Still I wonder when companies will start firing workers en masse.

Intriguing. I always pictured being a DNS server would require industrial grade infrastructure. Do you run a DNS server?

HEY! Maybe my Namecoin will be worth something someday. Smiley
Pair of them. Oddly enough I ran them on a Sun 386i back in the 1990's, think 25mhz 386 CPUs.

BIND is a bit of a pain to configure, but not really that bad once you start working on it.

You're shivering needlessly.  Your body is trying to warm you up to aid it in fighting the illness which is why you are shivering.  Instead of suffering like that, you could just get in a nice warm bath/shower.  It stops your body from shivering, relaxes your body (and mind), likely reduces any congestion you may be feeling and allows you to then curl up under the blankets and sleep like a baby.  Just don't let your temp go above 40.5°C (105°F) instantaneously or over 39.4 °C (103°F) for a longer than 48 hours.  Also it's best to have help getting in and out of the tub/shower as you may be dizzy.

Hm. I never thought of that. Thanks!

Wonder when the helicopters of money will start being dropped. My guess is it will only be on Red states, just prolonging the agony.

I guess if it goes really bad and lasts a bit, I might buy the house cheaper (still have a good chunk of cash fortunately, and mortgage rates are crazy low).

Pretty much. What saved me in 2008 was having a small metal box with some cheap shit silver coins, a couple of gold coins, and probably a K in cash. I ran my fingers through it and pretended to be a pirate. Thus I felt I had wealth and didn't sell my stocks and such.

Always have something you can draw down in a crisis so you don't have to panic sell everything. Looks like gold at the moment is holding at 1700 ish, so that's not too bad of a deal if you need some quick cash. Now, can the virus live on gold coins?

You will know it's bad (and this chart is accurate) when you hear Republicans suddenly clamoring for "early voting".

So my stock portfolio is going down. Most of it I can't do anything about it (company stock, must keep 5 years before selling, free stock as a compensation).

But my BTC portfolio is also going down !

Not that bad (for either) but still, I would have expected an inverse correlation, or at least BTC hodling better.

Gold is going up in the meantime, I know someone is gloating...
Welcome to 2008. I remember when Gold, stocks, and just about everything was going down. It was a fucked up time. And here we go again.

Still fail to see how that's worse than current default DNS hijacking by ISPs?
https://en.wikipedia.org/wiki/DNS_hijacking#Manipulation_by_ISPs
Centralized. FBI just goes to one source (Cloudflare) for all their shopping needs.

Also remember the golden dot.com rule: If you're not paying for the product, you are the product. CF isn't doing this for the love coming from their warm hearts.

is NextDNS any better?

Part of the problem is (in the US) *any* cloud service data can be demanded at any time without a warrant. This to me is annoying, but welcome to the warm delight that is the PATRIOT act. At least if you run your own DNS they will either have to hack it (pain to do), get a warrant (waah) or show up at your house with a battering ram.

Mileage may vary.

I'm watching ATARI 800 setups on ebay.  I don't know if anyone here is hip to M.U.L.E. but it is one of the best games of all time IMO and that is the best system for it.

MULE is good, but Star Raiders was without a doubt revolutionary. An excellent game for the ages.

1439  Bitcoin / Mining support / Re: Do antminers use power when on but not connected to the internet? on: February 27, 2020, 01:01:59 AM
Yes. Antminers run the boards with a certain amount of power even when not mining. The clocks are on as well, meaning it's pretty easy to find bad chips, but you also can't leave a board out of an antimer with +12 connected for a length of time otherwise it will get very very warm (BTDT with an S7 board)

If anyone's bored I can check the values but I recall it being about 200 watts per board.

Dragonmints do NOT do this, which makes finding bad chips a real pain in the ass.

Clean water would be my chief concern. Here's a good checklist in case you expect to be without power and/or clean water for a few weeks. It's a hurricane preparedness site but this is the stuff you'd need to think about...
https://hurricanesafety.org/prepare/hurricane-safety-checklists/

I used this last time I was in a hurricane, worked great, there are several similar products on the market...
https://www.amazon.com/gp/product/B00W2BQT4G

And of course, it's important that you know how to use all this stuff *before* you need to.
Water is a serious bitch, the stuff is heavy and takes up a *lot* of space. That said, 5 gallon jugs are not too expensive and every house has both a nice 40-50 gallon water tank, a couple of gallons in the pipes in the event things are really weird. I've tried rain barrels, but they fall apart after a few years and collect mosquitoes and odd things. Maybe a cistern.

If it rains where you live park your truck so water collects in the bed. Instant water for toilet flushing.

(Edit: That aquapod thing is a pretty good idea. I'll keep that in mind)
