Pv Comm Epever Real Time Modbus Register 12562: Power components Temperature

Technical Definition

The register Power components Temperature at address 12562 is used to monitor power components Temperature on the Pv Comm Epever Real Time.

• Protocol: Modbus RTU
• Data Type: S WORD
• Unit: �C
• 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 Power components temperature (Address: 12562)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=12562, 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: "Power components temperature"
  address: 12562
  value_type: S_WORD
  unit_of_measurement: "�C"

💡 Engineer's Insight

Analysis: Power components Temperature (°C). Indicates the Temperature of internal power components.

Troubleshooting: Overheating suggests excessive load, poor ventilation, or component failure. Inspect heatsinks and airflow.
