Deye Inverter Entities Sensor Modbus Register 211: Name inverter name battery max discharge current

Technical Definition

The register name inverter name battery max discharge current at address 211 is used to monitor name inverter name battery max discharge current on the Deye Inverter Entities Sensor.

• Protocol: Modbus RTU
• Data Type: U WORD
• Unit: A
• 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 max discharge current (Address: 211)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=211, 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 max discharge current"
  address: 211
  value_type: U_WORD
  unit_of_measurement: "A"

💡 Engineer's Insight

Analysis: Maximum current (Amps) the battery can safely provide during discharge. Affects load handling capacity.

Troubleshooting: Zero implies discharge is disabled or a critical battery fault. Verify inverter settings and battery BMS status.
