this is my powerwall, consisting of 1400 cells in a 200p7s configuration, expandable as long as there's wall . Up and running since a few weeks, currently 9 days non-stop off-grid, still counting .
As you can see from the pics, I took the word powerwall literally and hung 70 packs of 20 cells on a wall in the basement. Connections are all made from copper water tubes (cheapest copper source in town) with a little bending and soldering work.
One vertical row is roughly 1kWh, overall 420Ah / 10kWh. Still in conjunction with my older battery setup (aka the tower of power), 8 sealed lead-acid solar batteries with 940Ah.
Any feedback appreciated
P.S.: This is my grid consumption for the current month so far, daily average now is 21W / <0.5kWh - so my house consumes as much power as a laptop :
