Could you see any messages about ModBus communication errors in HA log file? And maybe there are some changes in register definitions. SH10RT-20 was unknown when the HA modbus definition was created. Could you try to get a new modus register definition from SunGrow? |

I guess the discussion title tells almost everything. Just installed and connected to a SH10RT-20 equipped with a 12.8 kWh Sungrow battery pack.
Any idea of what is wrong ?
