Is BMS restricting Inverter Charge/Discharge
Have 9 x 4.8KW batteries and 2 8KW Inverters in parrallel and set to charge/discharge at 160 each toatal 320 amps but only ever charges at 220 amps.
When discharging at over 11KW ( 230 amps DC) Master inverter trips on - Fault 34 - AC_Overload_Fault and Slave shuts down on
Fault 41 - Parallel_System_Stop, and supply goes OFF.
LiBMS shows Charge urrent Limit: 220 amps Discharge urrent Limit: 230amps.
How can you change this?
Should not the inverters just use Grid supply rather than shut down?

data sheet shows below. I'm sure it's the battery temp trottling your charge and discharge Amps
