3 phase Quattro system shutdown with no explanation

System consists of

3 x Quattro 8000 in 3 phase config - Product Version 2655 Firmware 487

1 x SmartSolar RS 450/48/200 MPPT - Product ID 0xA111 Firmware v1.05

Cerbo GX with touch screen

6 x Revov R 100 Batteries

System goes completely dead once or twice a week without any explanation - usually mid-afternoon. No error codes and nothing written to the log.

It requires a full shut down and reboot to get it back again. Does not restart automatically.

Does anyone on this forum have any advice or suggestion ?

as a guess - I would be looking at the batteries BMS turning off because of a high cell voltage .


as mid afternoon would meen that the batteries are then full from the solar charging. maybe look at how your BMS is setup.

otherwise a far more detailed system setup and a diagram would be of help
