Hello from New Zealand (Blenheim)
#1
I've finally got the ball rolling on my own power wall, although it's based in a commercial UPS rack so power rack is more suiting.

So far:
5kw PV setup with Micro inverters
Solax Hybrid 100amp inverter/charger for integration of the power rack to house supply.

400-500 18650 cells so far. Ave Capacity of 2500mah

Safety is important on this install I am double fusing cells, a shunt trip for BMS and another for environmental monitoring, rack earth bonding, cell cooling and room ventilation are all planned.

Looking for other Kiwis and places to get cells from :-)

Ill be watching very closely as I plan something similar. I also have the solax charge controller and inverter settup.

PS where has your cell supply come from thus far? I have a free supply of cells that comes in at around 100 good cells a month. I am experimenting with supplimenting it to boost the speed of cell gathering by purchasing a bunch of battery packs from a computer shop for $6 a kg. will let you know how that turns out.

PS where did you get your rack from?

I am planning to build mine from custom wood and ply left over from our house build. my mantra for this project is SAFE, CLEAN and CHEAP.
