Hey,

I have been watching you channel for a while and am in the middle of building my own 2P 7S (80P) bank and have taken a lot from they way you have and many others have done. This forum and your channel has been invaluable.
The one thing I have not found and am interested in is your shed, Did you build a dedicated shed for safety or for space and I would really like to know the materials and dimensions of your shed, I know this should be simple enough to work out and build, maybe you have ideas on how you would do it different or better.

Thanks again to everyone who contributes to this community, right now I'm just a leech and am not giving back, but hopefully one day I'll be in a position to provide feedback and assistance.

Thanks from South Africa.

Thank you Pete for sharing so much information about your powerwall! You have inspired me to build my own 10kwh wall to power my off grid tiny home!

Also thank you for sharing the files for the 80p cell mounts! I am able to get them made up locally and that will be a tremendous help with saving space. I sent you and mark each a thank you donation for you time and efforts. Look forward to seeing your future progression and being able to share my own within the community

Thanks for tuning in buddy, I don't think it's leaching if your learning. And you share your experiences later down the road for others to leach from Tongue

I will definitely be starting a build thread soon and share any build photos I take while getting the brackets done! I have 4 being cut out by a good friend as a sample run and we will be powder coating them in house, Id be happy to ship to anyone in the US for cost of materials and postage, I will get a total sum together once we are done. Thanks again!!

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?

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.

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
