Don't burn your house anon. Go with the lithium iron phosphate.Yes larger and heavier but irrelevant at home. They are also cheaper, safer and more durable.
That would make for unfeasibly high fire insurance rates. Not just because of the hazard it presents itself but because a fire from another source that set it off would insure total house destruction.

>if it's so simple and easy to save that kind of money or generate your own power and never worry about blackouts?
A solar setup and battery backup are most effective at saving money when you have expensive electricity or if blackouts are a meaningful concern where you are. Tons of people in places like California are going solar with backups for exactly this reason (and to be able to save money by using the system to offset their electricity consumption to take advantage of different pricing during off-peak hours)
If short term blackouts are your primary concern, then a generator and a couple cans of gas might be a more effective solution.

What if you live somewhere that is sunny 99% of the time, would it be worth it to set that kind of system up to put energy back into the grid and get a payout from the electric company rather than paying for it?
1 year ago
Anonymous
"it depends" because different places have radically different payout schemes with their power company. In my area you cannot receive a payout from the power company; you only get a credit towards your bill, and even that is at a cost recovery rate instead of retail price, and you can only have a maximum of 10kW.
There are other areas where you get paid more than retail rate when you sell power back to the grid, but this type of arrangement has become less and less common over the years as solar has become cheaper and more widespread.
Check with your local power company.
You can also look at calculators online to determine how long it would take your system to pay for itself based on your location, power usage, and local prices of electricity.

I too am doing the diy thing. I think for sub 3 grand i should be making power with 1kw of panels, with charging capability for 2.5k more. Pretty primitive 12v system with 400 amp hour of lfp batts. But i do everything with generators and a single 100w panel now so....
Hadnt put together to dump excess into "sunken cost" loads
Smart, ty
Most people have absolute 0 knowledge of power systems, and this one involves messing with hundreds of amps DC, as well as AC voltages, so it's not a super beginner friendly project. Still a lot safer than building a gigantic 18650 nickel pack though.
Also you need to have at least $.15/kWh total cost of electricity and decent sunlight hours to reach a ROI of 10-15 years.

The problem with his videos is that they are for the upper middle class. He goes on about how he was poor and homeless and he could easily go back to living like that. But now he has money that a lot of us never will. It changes people and it is funny when they say it doesn't. As he just bought an electric truck after saying he wouldn't because it wasn't worth the money.
The best poor man's setup I can think of is just a nice backup power system that allows you to keep one room with electricity and heating and cooling. The 8 bit guy system. You obviously can do more labor than he did to save money.

He's literally using the chinkshit garbage in his own home. He's not using $2000+ Victron. His inverters are still $2000+ because they are high power, however the same system with Victron would be $20k.
Obviously if you're dirt fricking poor then you can't afford a solar system, but that's not because solar is overpriced, it's because you're dirt poor. Depending on how you use power and how much you pay for electricity, you can reach a ROI of like <5 years if you cheese it.

My perspective was given the budget for conduit, wire, pedastal, machine time, and wrangling with the power company to connect to the grid, could you make your outlets work? I did it backwards from contractors where i built the house with hand tools, charged batts of solar, and started a generator anytime i needed more than 5 amps or so.
Is starting, maintaining and fuelling a generator when i want to vacuum a price im willing to pay for the payoff of no connection fee? For me, turns out at least for now the answer is yes.
If i wanna cry uncle at any time, the pole is always there. then i switch grounds and wires around and i have a ready to go paid for array and battery backup. Already wired up before gnarly ac amps come in. Sick.
While a chest freezer is still luxury, might as well take advantage. Ill get soft someday.

Tesla powerwall is well known nickel based. Tesla currently doesn't use LFP in anything. Even if it was LFP, it doesn't make any sense to use 18650 LFP as opposed to big prismatic cells, the 18650 is more expensive even.
There are deep cycle sealed lead acid batteries. That’s said I should probably not post as I don’t really know shit about shit about the topic (not that that’s actually stopped anyone here before).
That's already the deep cycle ones being compared. LFP is maybe 30-50% higher initial investment for 500%+ lifetime.
Though anon's numbers of 20,000 cycles are beyond spec, the spec is usually around 5000 cycles at 0.5C charge/discharge to 80% capacity. But even then, deep cycle lead acid can, at best, do 1000 cycles in similar conditions, probably less.
Of course, in a residential solar application you are usually under the spec, therefore 20k cycles isn't impossible, while lead acid will die after 1000 regardless.
To be honest - Lead Acid just does not hold a candle to LFP. LFP 20,000 (54 years) charge-discharge cycles if going a full discharge, you can make it 40,000 by doing a 1/2 discharge (109 years) whereas Lead Acid has a 5 to 7-year life span and will also self-discharge on you if you do not keep a trickle charge running to it.
In the end, you will pay more for Lead Acid than you will for LFP.
There are a lot of guys who build their own powerwalls with lifepo4 cells, if you search this you will find a lot of practical designs already done so you can choose or improve one of them
how do you pump the water to the top of the water tower? solar panels connected to a pump?
not a terrible idea
This only works if you have a large hill on your large property. The amount of water and the height difference you need is really big for storing one or two dozen kilowatthours, compared to buying $2000 worth of LFP batteries there's no way it's an efficient setup.
If you have a ~50 meter head, which most people don't, each cubic meter of water pumped can deliver about 0.1kWh of energy. With a 10 meter head, it's 25Wh. So you need to store about 40 000 liters with a 10 meter head difference for the same 1kWh storage capacity that a tiny 10x20x10cm 1kWh LFP battery can deliver for $100. Not to mention that the pump system will be considerably less efficient than the battery system.
Use prismatic cells instead. You can also just buy ready made battery packs that don't cost thousands. Power wall is a ripoff for stupid Californians with too much money
The guts were 1200 used and the batts have a 5 year warrantee (hah lol) and cost 16.
Ill have to buy a ground rod but all wire except the dryer cord from the inverter to panel came with the system.
Its really not that unattainable for most PrepHole folks if they realized what it was. Just 4/0 wires and 250 amp dc breakers seem "gnarly"
Sorry, i didnt realize how unconventional this was, it made sense to me.
Yeah, i put things where i wanted em, kitchen stuff together etc. its my house. Ive gotten that feedback a lot though.
Theres also a lot of future infrastructure that isnt in yet that i left wire for behind the panel that i tried to leave myself not-dumb room for. Theoretically that bottom right one will be the only loner, and its the service outlet right there. Other outlet is genny power in. Im not the guy that made the deadman schizo (they) thread tho.

Tesla powerwall is well known nickel based. Tesla currently doesn't use LFP in anything. Even if it was LFP, it doesn't make any sense to use 18650 LFP as opposed to big prismatic cells, the 18650 is more expensive even.
Better still, if he’s got the space (and his floors will support the wright), why not just lead-acid? Simple, proven tech.
Their life cycle stinks.
Get lifepo4 cells from US supplier and build your own 48v system and get a good inverter
There are deep cycle sealed lead acid batteries. That’s said I should probably not post as I don’t really know shit about shit about the topic (not that that’s actually stopped anyone here before).
That's already the deep cycle ones being compared. LFP is maybe 30-50% higher initial investment for 500%+ lifetime.
Though anon's numbers of 20,000 cycles are beyond spec, the spec is usually around 5000 cycles at 0.5C charge/discharge to 80% capacity. But even then, deep cycle lead acid can, at best, do 1000 cycles in similar conditions, probably less.
Of course, in a residential solar application you are usually under the spec, therefore 20k cycles isn't impossible, while lead acid will die after 1000 regardless.
To be honest - Lead Acid just does not hold a candle to LFP. LFP 20,000 (54 years) charge-discharge cycles if going a full discharge, you can make it 40,000 by doing a 1/2 discharge (109 years) whereas Lead Acid has a 5 to 7-year life span and will also self-discharge on you if you do not keep a trickle charge running to it.
In the end, you will pay more for Lead Acid than you will for LFP.
Interesting, thank you for educating me.
There are a lot of guys who build their own powerwalls with lifepo4 cells, if you search this you will find a lot of practical designs already done so you can choose or improve one of them
Just get a water tower and a turbine. Plus you get water storage
how do you pump the water to the top of the water tower? solar panels connected to a pump?
not a terrible idea
>how do you charge the power wall?
This only works if you have a large hill on your large property. The amount of water and the height difference you need is really big for storing one or two dozen kilowatthours, compared to buying $2000 worth of LFP batteries there's no way it's an efficient setup.
If you have a ~50 meter head, which most people don't, each cubic meter of water pumped can deliver about 0.1kWh of energy. With a 10 meter head, it's 25Wh. So you need to store about 40 000 liters with a 10 meter head difference for the same 1kWh storage capacity that a tiny 10x20x10cm 1kWh LFP battery can deliver for $100. Not to mention that the pump system will be considerably less efficient than the battery system.
That's a lot of spotwelds to frick up
Damn good at fricking up spot-welds myself
Enjoy building your own BMS, or at least post pictures when your house turns into a fiery portal to hell.
Use prismatic cells instead. You can also just buy ready made battery packs that don't cost thousands. Power wall is a ripoff for stupid Californians with too much money
You won't do it.
I will, and I just won't tell you about it
(Lie)
Tesla is using 21700s these days, not 18650s.
And, it's not the battery, it's the circuits to connect to the house with. Good luck.

Don't. I saw an electric car burst into flames today for no reason.
Use LFP and you will avoid most of these types of problems. Even electric cars are moving to LFP to get away from the cobalt.
The guts were 1200 used and the batts have a 5 year warrantee (hah lol) and cost 16.
Ill have to buy a ground rod but all wire except the dryer cord from the inverter to panel came with the system.
Its really not that unattainable for most PrepHole folks if they realized what it was. Just 4/0 wires and 250 amp dc breakers seem "gnarly"
>that breaker spacing
It’s fine per the code, but I’m triggered.
Sorry, i didnt realize how unconventional this was, it made sense to me.
Yeah, i put things where i wanted em, kitchen stuff together etc. its my house. Ive gotten that feedback a lot though.
Theres also a lot of future infrastructure that isnt in yet that i left wire for behind the panel that i tried to leave myself not-dumb room for. Theoretically that bottom right one will be the only loner, and its the service outlet right there. Other outlet is genny power in. Im not the guy that made the deadman schizo (they) thread tho.
>this moron saying Will Prowse is a shill that only says to buy the highest high end shit and gives bad advice while praising 8 bit guy's horrible setup
This is a gag thread right
It’s PrepHole my man, they’re all gag threads.
