Deye Inverter Entities Sensor Modbus Register 72: Name inverter name battery charging total

Technical Definition

The register name inverter name battery charging total at address 72 is used to monitor name inverter name battery charging total on the Deye Inverter Entities Sensor.

• Protocol: Modbus RTU
• Data Type: U DWORD R
• 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 battery charging total (Address: 72)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=72, 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 battery charging total"
  address: 72
  value_type: U_DWORD_R
  unit_of_measurement: "kWh"

💡 Engineer's Insight

Analysis: Total accumulated energy charged into the battery (kWh). Indicates overall battery charging activity.

Troubleshooting: Zero value could mean battery is not charging, charging circuit fault, or sensor issue. Check inverter settings and battery status.
