this may have been touched in the thread, but with such a larger system 30Kwh,50Kwh how many inverters are needed or is there one main source? sorry if the answer is here already. totally new to this.

Hey Pete. A thing I want to ask you about your system. I've watched a lot of your vids (so maybe I've forgotten haha). If you've covered them already, please share a link, and I'll have a read, or a watch.

With regards to the Batrium BMS and Longmons - I think I have a handle on how they work, but what I don't understand is why you have to periodically disconnect the system and spend days balancing. Is this not what the Batrium system is supposed to do, or is it just the current capability of the Longmons isn't enough to keep up. Do packs only go majorly out of balance because of a faulty cell(s), mismatched cells, or are there other reasons?
My issue is load - We use a lot of energy and even with 9wk of solar it still doesn't charge the batteries every day so batteries don't balance ALSO these cells were really poorly built so some have now got heaters and the batteries them selves are very imbalanced these days (currently working on fixing this) I also have my WM4 setup so it doesn't waste too much energy so have it starting to balance at 4.1v if I changed that to 4.0 volts balance would be much better all the time. End of the day my build quality was and still is in a BETA state lol

is not the size of your storage it's the size of your load - 2x your max expected load and you'll have enough inverters

the download link of the CAD files for the mounting-system seems to be down, maybe because of the new forum software update?

Does anybody can provide the "normal" 80p version CAD files? I would like to ask around in my region if someone can do this kind of work

I reuploaded the CAD files I saw on page 1 as attachments. Can you please try again?

thank you.
I tried to build your mounting system for my own, without CAD

Hi
Thanks for the files for your powerwall bracket.
I didn't have idea to how to fix on my wall my 30 packs 13S10 ;-)

Thanks a lot
