Deye Inverter Entities Advanced Modbus Register 262: Name inverter name battery voltage timezone1

Technical Definition

The register name inverter name battery voltage timezone1 at address 262 is used to monitor name inverter name battery voltage timezone1 on the Deye Inverter Entities Advanced.

• Protocol: Modbus RTU
• Data Type: INT16
• Unit: V
• 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 voltage timezone1 (Address: 262)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=262, 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 voltage timezone1"
  address: 262
  value_type: INT16
  unit_of_measurement: "V"

💡 Engineer's Insight

Analysis: Represents the battery voltage setting for the first time zone (e.g., 0-24h). Units: Volts (V).

Troubleshooting: Zero indicates no configuration or a communication error. Check inverter settings and Modbus connectivity.
