Epever Scc Entities Sensor Modbus Register 13074: Scc name PV Generated Energy Total

Technical Definition

The register scc name PV Generated Energy Total at address 13074 is used to monitor scc name pv generated energy total on the Epever Scc Entities Sensor.

• Protocol: Modbus RTU
• Data Type: U DWORD R
• Unit: kWh
• 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 PV Generated Energy Total (Address: 13074)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=13074, 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 PV Generated Energy Total"
  address: 13074
  value_type: U_DWORD_R
  unit_of_measurement: "kWh"

💡 Engineer's Insight

Analysis: Total energy generated by the solar charge controller (SCC) in kWh or MWh. Indicates cumulative system performance.

Troubleshooting: Zero value may indicate a new installation, a reset of the SCC, or a communication error preventing energy accumulation.
