Deye Inverter Entities Sensor Modbus Register 108: Name inverter name pv energy today

Technical Definition

The register name inverter name pv energy today at address 108 is used to monitor name inverter name pv energy today on the Deye Inverter Entities Sensor.

• Protocol: Modbus RTU
• Data Type: U WORD
• Unit: kWh
• 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 pv energy today (Address: 108)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=108, 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 pv energy today"
  address: 108
  value_type: U_WORD
  unit_of_measurement: "kWh"

💡 Engineer's Insight

Analysis: PV energy generated today (kWh). Daily energy production from solar panels. Tracks current day's performance.

Troubleshooting: Zero means no production today. Verify sunlight availability, panel condition, inverter operation, and grid availability. Check for shading.
