According to an old thread, the patents are soon to expire on the LFP cell chemistry. Have anybody here tried to or heard about somebody that boldly manufactured a home made LiFePo4 Cell?
To me, finding relevant long lasting electric DIY friendly equipment that works together without collapsing world economy and bringing our species to the brink of extinction is a highly technical aspect.
Elon could have built a billion dollar battery factory in Chilean northern desert where the Lithium is Harvested, or anywhere on ship route upwards from there. He wouldn't have to hire slaves, cause wages are very low. Cleaner tech is coming. We should have cheap, earth abundant material...
He would probably disagree with you on that. Anyway, Elon has been Shanghaied by Beijing too so they can replace the current source code of Twitter with the source code of Chinese Wee-chat.
Actually Watts _Do_ care where you are:
In the USA / Canada / Mexico / North Latin America, you need a 120V / 60Hz inverter. Elsewhere that can be 230V /50Hz.(or 60 Hz)
How is the LiFePo electrolyte toxic? How bad is it? Lethal? Permanently Damaging? I know many of my "High school" curiculum chemical experiments needed to have that specially designed closet plexiglass like actively chimneyed and ventilated nische.
I saw some Youtube home-steader set up a relatively decent pv system.
There must be sunnier parts. I seem to recall warm childhood summers down in Cornwall.
This thread is about the geo-political context of DIY solar forum. I find it hard to find sustainable equipment to use here because Everything here is centered around China producing us into global mass extinction.
I need the Semi flex cells loose for manual solder as I am fitting them into a complex pattern on a home designed, home built experimental vessel. The flex cells sold on Aliexpress for sure look suspicious. The one I am looking to buy is called Maxeon c60, and is supposedly of a higher quality...
For me the price is less important than actually receiving equipment that work for a long time, and doesn't cause global annihilation. Will that yellow box charge a 24 or a 48 volt system?
There must be a better way to make these. Now all cells are made from baked Silicon ingots, that are sliced ultra-thin by some magic saw blade.
Then they have to be framed and soldered manually.
Before I start designing my off grid system it would be helpful to know if there are people out there that lost equipment caused by CME s, and similar. What resources are there to read up on? I tried google, etc but only grid based design problems come up. Apparently soil structure is a big...
Not true. Solar Edge f ex is Israeli but sadly proprietary. Sunpower is from Singapore, Rich Solar I believe is from India. I also believe there is Australian tech out there. For my Solar shed I can settle for cheap AGM batteries. I am also able to solder tohether my own MPPT solar charger if I...
SMA solar equipment seem to be high in demand now, judging from recent news, but shipping disruptions are affecting their sales figures.
So it's either Victron, or SMA?
A lot of sailors choose Victron, since they seem water resistant. and water resiliant. SMA does not really seem to target...
Victron is a highly respected brand. Thanks for sharing this. It's news for me! India is a democracy. Sadly, many European countries seemingly have forgotten how to make businesses grow exponentially, and that is what's needed to create true change.
Expensive SMA seems a bit overkill for my temporary solar work shed.
I think me DIY-ing together my whole system will do more for changing the geo political context of DIY Solar than Me pushing more money into SMA.
Also, this thread was supposed to be about D I Y solar forum and its responsibility towards not only US citizens, but all of us. By promoting us to buy from Autocracies, we arrive into living in an autocracy.
A Chinese Communist Party controlled national treasure?
He just sold of half of his Tesla shares, no wonder why. Elon is dope when it comes to bringing the world into the future, but Letting his new car company with all of its enthusiastic shareholders become shanghaied by Beijing was a major...
Outback got some really nice reviews on Youtube. However I seem to recall it's a rebranded China product. DIY means put together in your back yard. I will not invent a new way to do MPPT, and I will not invent a new way to convert DC to sinus AC. Loads of smart people have done this before me.
Example: First Tesla cars were ridiculously expensive and unreliable. Now their price have gone down to a reasonable level reliability has improved as well .
Li Fe Po Battery technology is toxic.
It has to be purchased and shipped from an autocratic China, with no laws protecting customers, and...
