Epever Scc Entities Sensor Modbus Register 36867: Scc name Overvoltage Disconnect Voltage

Technical Definition

The register scc name Overvoltage Disconnect Voltage at address 36867 is used to monitor scc name overvoltage disconnect voltage on the Epever Scc Entities Sensor.

• Protocol: Modbus RTU
• Data Type: U WORD
• 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 scc_name Overvoltage Disconnect Voltage (Address: 36867)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=36867, 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: "scc_name Overvoltage Disconnect Voltage"
  address: 36867
  value_type: U_WORD
  unit_of_measurement: "V"

    PLC -- GND --> Device

💡 Engineer's Insight

Analysis: Voltage threshold (V) at which the SCC disconnects charging to prevent overvoltage damage to the battery.

Troubleshooting: If battery voltage reaches this point, it indicates overcharging. Check charging parameters or PV input.
