Deye Inverter Entities Sensor Modbus Register 218: Name inverter name battery capacity restart

Technical Definition

The register name inverter name battery capacity restart at address 218 is used to monitor name inverter name battery capacity restart on the Deye Inverter Entities Sensor.

• Protocol: Modbus RTU
• Data Type: INT16
• Unit: %
• 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 capacity restart (Address: 218)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=218, 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 capacity restart"
  address: 218
  value_type: INT16
  unit_of_measurement: "%"

💡 Engineer's Insight

Analysis: Battery SoC (%) at which the inverter will restart charging or supplying power after a shutdown.

Troubleshooting: Zero might signify an issue with the restart condition or communication. Verify BMS and inverter settings.
