Deye Inverter Entities Sensor Modbus Register 175: Name inverter name ac output power

Technical Definition

The register name inverter name ac output power at address 175 is used to monitor name inverter name ac output power on the Deye Inverter Entities Sensor.

• Protocol: Modbus RTU
• Data Type: S WORD
• Unit: W
• 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 power (Address: 175)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=175, 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 power"
  address: 175
  value_type: S_WORD
  unit_of_measurement: "W"

💡 Engineer's Insight

Analysis: Instantaneous AC power output from the inverter to the grid or load. Units: Watts (W).

Troubleshooting: Zero if inverter is off, not producing power, or load is zero. Check inverter status and load.
