Deye Inverter Entities Sensor Modbus Register 70: Name inverter name battery charging energy today

Technical Definition

The register name inverter name battery charging energy today at address 70 is used to monitor name inverter name battery charging 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 battery charging energy today (Address: 70)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=70, 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 energy today"
  address: 70
  value_type: U_WORD
  unit_of_measurement: "kWh"

💡 Engineer's Insight

Analysis: Total battery charging energy generated today by the inverter. Unit is typically kWh.

Troubleshooting: Zero value means no charging occurred today. Check battery status, charging source, and system operation.
