Sounds like a wonderful success. It almost sounds like you're complaining... ??
Make your bush bars self from alu strip, make then 2 x the square diameter as from copper and you have even a lower resistance and it is a lot cheaper .

True ! but you was going for the cheapest options ! but if you compress your cheap lithium cells they do not have to be flexible , but i can be wrong.But not flexible, like these:
What can I say... I expected at least some fireworks, maybe something to write about/video. I did not expect this all to go this well - I mean as @tictag said at the beginning of this thread: "Buying the cheapest possible components and shoving 10,000W of electrical energy through them. Never has that before been problematic! "

What's your inverter brands/models (both high and low freq)?
edit: just think, if you wouldnt have replaced the high frequency inverter, you might have been able to cause fireworks eventually. ?
TOP! that is the spirit ! i got it ! never thought about this solution and i have an hammer , whahahaWell, I didn't really go for the absolute cheapest ones. I went for the cheapest stuff (under 10K in total) that had potential to be good (enough) to handle 10kW. I make those flexible bus bars myself, and they're not that expensive if you DIY actually: it's just copper braid (I think I got two meters if I remember correctly, for 6 Euro/meter) and copper pipe (for something like 15€/meter).
Does it have a built-in transfer switch? if not, Did you install a transfer switch? will it pass a/c through while it charges? That's a nice beefy inverter. Mine is only 4kw.
Congratulations on your success. I have been following your thread for along time now, and I have the same stuff as you, and it is good to hear of others doing it rightWell, I didn't really go for the absolute cheapest ones.

Do you have any form of energy monitoring/tracking?
Oh cool!I wrote the drivers for my components - they all have RS-485 interfaces. That said, I have to do this part better - it's not been a priority.
Sport Copter Vortex gyroplane,, Damn that was cool.I'm not sure you can even call it "counterfeiting." The Chinese have a whole different view of intellectual property. They are portrayed as bad actors for "stealing" intellectual property from other nations, but in their system it's considered fair game. Come up with a new idea? Great - better get it into production and make some money, not sit on it for 10 years waiting for the highest bidder, or use it for patent-trolling.
I play with electronics, and right now I'm working on a Chinese-made CB radio that's sold in the US as a ham transceiver. It's manufactured by Qixiang Electron Science & Technology Co., Ltd., and branded as Anytone, QYT, or BlueSkySea. In the US, it's sold under the Stryker brand. They all use the same PC board, stuffed with varying features by brand, but there's no guarantee the PC boards all come from the same place, or are stuffed with the same grade components. So far, the quality I'm seeing is much better than a few years ago, although some of the semiconductors are questionable counterfeits or mystery generics.
The scandals a few years ago concerning toxic drywall and baby formula seem to have awakened an understanding in China of the value of brands. The government is certainly sensitive to the damage done to the country's manufacturing image by bad products, and has prosecuted some company execs for the more egregious cases.
I believe that in the near term, the worst junk coming from China will have been manufactured to the specs of western importers looking for lowest cost, not driven by actual Chinese brands. They're trying to rise, but still have a long way to go. Chinese electronics quality is just catching up with what Japan was making in 1970, and in some product lines they're doing the same thing Japanese manufacturers used to do - pushing equipment with goofy, unwanted features poorly targeted to the needs of western markets.

The first case of intellectual property theft that I remember from history was when someone stole a silkworm from the Chinese.I'm not sure you can even call it "counterfeiting." The Chinese have a whole different view of intellectual property.
darn tootin, real life is use it or lose it. can't beg the law person to give me the muscles of my youth, why do it with ideas. lots of electronics in the USA that are considered to be very high end say designed in USA made in China.I'm not sure you can even call it "counterfeiting."

Wow! Nice work. And thanks for sharing.
I am tempted to copy this. Though I don’t think I would put my version on the roof. I’d need to opt for a stand-along shipping container energy station with an AC line to the cabin. This may tilt the scale.
