Device Sofar Ktlg3 Modbus Register 26: Name inverter name ac output energy today duration

Technical Definition

The register name inverter name ac output energy today duration at address 26 is used to monitor name inverter name ac output energy today duration on the Device Sofar Ktlg3.

• Protocol: Modbus RTU
• Data Type: U WORD
• 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_today_duration (Address: 26)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=26, 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_today_duration"
  address: 26
  value_type: U_WORD
  unit_of_measurement: "min"

💡 Engineer's Insight

Analysis: Today's Energy Yield Duration (h). Operational hours recorded for the current day.

Troubleshooting: Tracks daily operating time. Zero suggests the inverter did not operate or was not online for the day.
