Hello everyone, I wanted to share some pictures of my powerwall build. I'll be adding a few more pictures of the mobile application I built to monitor this setup. Overall this project was a few months in the making and went very smooth. The only advice I can provide is to not rush and build when you have the time to spare.

The package consists of:

- 16 Valance Batteries
- 2 Eaton electrical panels on the cabinet exterior . (input and output AC)
- 1 small electrical enclose for 48v DC input/output on the cabinet exterior . (Will be used to connect 48v DC Generator)
- 1 Midnite Solar DC panel which contains: Main battery breaker, pre-charge contactor + resistor, main contactor, 48v to 12v converter (BMS and Contactor Power).
- 1 valence High Voltage BMS modified to monitor a low voltage pack.
- 1 Canbus adapter to monitor BMS and Batteries.
- 2 LV5048 inverters (One is yet to be installed in the cabinet.)
- 1 Old Stock Nortel Telephone Battery Cabinet
- Other - shelf fuses, copper busbars, pvc shelf covers, terminal standoffs etc.

This fantastic I am working on something sillier using 16 UEV1 18xp modules. And two EASUN 5kw Igrid sv in parrallel.How did you get the ubms reprogrammed? XML hash cracking or did you get the BMS config software working?
