#TeslaPowerwall #DIY #40kWh
If are you wondering what's inside in a custom powerwall storage solution for PV system based on used batteries from a crashed Tesla Model S, take a look on this video.
This is the third day working to my DIY project based on Tesla Module S used batteries. In this video I finish almost all cable management and I prepare to finish all. Need to connect the batteries to the BMS and after that the only thing that need to be done is to power on the entire system.
In this video you will see all the cable management in his own case and all the fuses I used in oder to protect this batteries. I decide to put 2 contactor that is connected to SIMP Bms and in this way when the batteries is over-charger more than 4.2v the system will shut down this contactor for prevent over-charging.
What do you think about this project and please let me know in the comment area bellow you taught and your suggestions.
