Solax X3 + Tesla 3 battery and Dala's Battery-Emulator

[Dala]

This happened to us several times before.
It was solved by connecting all GNDs. Solax, Lilygo (all on Lilygo), BAT.
Then it ran for 1 month without a fault.
The next time the battery was charged, the Battery on CAN was blocked,
and Liligo does not communicate on CAN, and PC USB,
MCP2515 communicates on Solax.
We don't know what the reason is.
I studied the Lilygo schematic and I don't like the power supply design.

The people on the Discord figured it out. It is due to not grounding properly:

Solax inverters

This software enables EV battery packs to be used for stationary storage in combination with solar inverters. - dalathegreat/Battery-Emulator

Hi @Dala
The system worked for 2 weeks, installed 2x lilygo v5.9.

Today there was a problem that the articles were being not balanced, see pictures.
The total voltage rose to 380V.
Previously, the maximum was 372V
The system shut down.
What could be the reason that the articles are not balanced correctly?
Thank you

The people on Discord had something related to this, would be better to talk to a Tesla LFP owner instead!
