Hey There,
i just wanted to show a bit of my diy powerwall beginning.
I got a bunch of cell of my work and i would like to unbundle them and combine them in a 24V or 48V combination with my existing pv system that has 5,61kWp. Maybe ill use a pip as a simple battery-charger. I think that would work
So this diyPW will become an ac-couppled system.
As you can see on the picture i have two chunks of those big blocks on the left. This are 10Ah LiFePo4 cells, so in total 360Ah == 1188Wh.
Im not sure how ill could implement them, im thinking about a buck/boost converter that lifts the voltage of this block to the "normal" lithium packs. Maybe anyone has done something similar? But thats futurework to do. right now im busy with charging and sorting all cells.
Regards
Carsten
