Technical Definition

The register name inverter name ac output energy total duration at address 1063 is used to monitor name inverter name ac output energy total duration on the Device Sofar G3.

  • Protocol: Modbus RTU
  • Data Type: U DWORD
  • Unit: min
  • Access: Read Only

How to Read (Python pymodbus)

Use this code snippet to read this specific value via RS485:

from pymodbus.client.sync import ModbusSerialClient

client = ModbusSerialClient(method='rtu', port='/dev/ttyUSB0', baudrate=9600)
client.connect()

# Read name_inverter_name_ac_output_energy_total_duration (Address: 1063)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=1063, count=2, unit=1)

if not result.isError():
    print(f"Raw Value: {result.registers}")
else:
    print("Error reading register")

client.close()

Integration (Home Assistant)

Paste this into your configuration.yaml:

- platform: modbus_controller
  name: "name_inverter_name_ac_output_energy_total_duration"
  address: 1063
  value_type: U_DWORD
  unit_of_measurement: "min"

💡 Engineer's Insight

Analysis: Total cumulative duration of AC output energy generation. Units: Seconds or Minutes. Represents the total operational time since installation.

Troubleshooting: Static or zero value might indicate a system fault, lack of solar input, or inverter malfunction preventing operation.
