Hi
When my battery gets to an low SOC (13%) it starts outputting "Internal Failure" Error messages.
Between 15% and 10% SOC the error appears and disappears every few minutes.
At 5% SOC the error is continous until the battery is charged up againe.
My System:
8x Pylontech US3000C
3x Multiplus2 48/5000 in 3 Phase
2x MPPT250/100
1x Fronius symo 15kw
Cerbo GX
The System is connected to the grid running ESS.
Is this error normal at that low SOC?
The system is running for 3 months now without problems. It´s the first time now reaching these low SOC, so the error did not appear until now.
