Richie`s Modular Powerwall (Germany) 21kWh+
#1
Lightbulb 
Hi all,

first of all many thanks for this forum and the helpful contributions :-)

Finally my project has started! Wohooo

For about a year I've been following the posts and had recycled
cells, read posts, recycled cells...
A half year and 2000+ Cells tested later i sold all used cells... puh!
I thought about it for a long time - I want to build a powerwall as long as possible - so I decided to build new cells.

My choice is the LG 18650 M36 3600mAh.

'Modular' because i start with a 14S60P Setup.

After everything works well i put 14x 60/120 more packs to the Setup.
Finaly im planing with round about 21-25kWh.

Hybrid Inverter: SolaX Hybrid II 3700 G2 feed from 14x 300W Panels
BMS: Batrium

But as always in life: First the work, then the pleasure :-)






The Powerwall is located in my Garage, Finished with Fermacell plates (non-combustible)







I added 2 140mm Fans + a Controller in the Housing, more Fans later







The housing is also equipped with Fermacell plates (two-layer). Safty first ;-)






 



All Packholders are ready and were produced by 3D printer.



Thats it for now - new Updates next week :-)

It was a final decision for new cells and not against used batteries. Used batteries will certainly work well in a DIY powerwall, but I wanted a powerwall that works as long as possible and trouble-free.

With regard to operational safety,
I also consider new cells to be better - but that is my personal opinion - it is as always in life, many roads lead to Rome. Smile


I live in Erkelenz, NRW, approx. 20km from Mönchengladbach.

Update:
Spotwelder (Sunkko 709A) arrived yesterday, i did some tests with some other cells and my 3A Glass Fuses to find a good welding setting.
Works well on Pulse 4P and Current set to 3.
Im wondering about that because Doromer used much higher current settings in his YT Videos.
I will do some more testing - maybe i do some Videos of this.
