Hi, I have a PV inverter on AC OUT with ESS and with “Optimized without battery life”, now im in off-grid. I am waiting for it to connect to the grid but the dynamic power limitation still shows 30 kW and nothing changing. Is this because the frequency control has a higher priority in off-grid than modbus?

So it only works when grid is connected?

CerboGx FW: v3.73, dynamic power limitation is enable and and communication is SunSpec with PV inverter
