May help with defining the state

  return hass.states["sensor.overall_state"].state == "0" ? "blue" :
  "transparent"
selector: '#standby'
type: fill

• bind: >-
  return hass.states["sensor.overall_state"].state == "1" ? "yellow" :
  "transparent"
  selector: '#selftest'
  type: fill
• bind: >-
  return hass.states["sensor.overall_state"].state == "2" ? "green" :
  "transparent"
  selector: '#normal'
  type: fill
• bind: >-
  return hass.states["sensor.overall_state"].state == "3" ? "orange" :
  "transparent"
  selector: '#alarm'
  type: fill
• bind: >-
  return hass.states["sensor.overall_state"].state == "4" ? "red" :
  "transparent"
  selector: '#fault'

Most of the energy total values sit over two registers. Your current config isn't reading these values correctly.
To read these correctly the value_type configuration parameter needs to be set to U_DWORD_R, i.e. by adding the line:
value_type: U_DWORD_R

Note that your lamda filter on this totals also needs to be corrected. It doesn't need to handle the negative values.

There is one parameter (Grid Import Total) where the values aren't on consecutive registers - 78 and 80. I don't know how to configure this & would need to read up in more detail.

I'm facing a poor performance getting data from the registers. Can you please explain the settings below and how they influence the behavior of the modbus connection?
I have continously "CRC Check failed" and "Duplicate modbus command" messages

modbus_update_interval: "5s"
settings_skipped_updates: "10"
query_throttle: "50ms"

Issue: When the load exceeds 5kwh, the battery entity exceeds 30 800%. Below screen grab:

Thanks for publishing this. I've been using your config to update mine.

The grid frequency sensor can have the device class set to "frequency". You may need to change the unit of measurement to "Hz" instead of "hz".

Hi
What do we need between the esp32 tx rx ports and the sunsynk rs485 port ?
Would that be a 3.3v rs232 to rs485 adapter ?
Possible to please elaborate and do you have a link of the hardware ?
Really appreciate it

I don't think this is a binary sesnor, but rather one that returns different values with different meanings.
This is my code for it.

  - platform: modbus_controller   # 244 Settings Energy Management Model
    modbus_controller_id: sunsynk
    name: "Energy management model"
    id: sunsynk_energy_model
    register_type: holding
    address: 244
    raw_encode: HEXBYTES
    lambda: |-
      uint16_t value = modbus_controller::word_from_hex_str(x, 0);
      switch (value) {
        case 0: return std::string("Selling First");
        case 1: return std::string("Zero Export and Limit to Load Only");
        case 2: return std::string("Zero Export");
        default: return std::string("Unknown");
      }
      return x;
