Technical Definition

The register name inverter name grid charge battery current at address 230 is used to monitor name inverter name grid charge battery 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 grid charge battery current (Address: 230)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=230, 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 grid charge battery current"
  address: 230
  value_type: U_WORD
  unit_of_measurement: "A"

💡 Engineer's Insight

Analysis: Current (Amps) setting for charging the battery from the grid. Used for off-peak charging or grid services.

Troubleshooting: Zero means grid charging is disabled. Check inverter settings, grid availability, and battery charge enable flags.
