Please properly detail your system, there is nothing here anyone can comment on due to the sheer lack of information.

Be clear, and specific.

You have 15kVA of inverter running off that small (unsupported) battery that is never going to work well.

Start by checking what the BMS is reporting.

What are the restart parameters set on the inverters?

What errors did/does the GX report?

What firmware on the cerbo/inverters?
