Epever Scc Entities Sensor Modbus Register 13070: Scc name PV Generated Energy Month

Technical Definition

The register scc name PV Generated Energy Month at address 13070 is used to monitor scc name pv generated energy month 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 Month (Address: 13070)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=13070, 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 Month"
  address: 13070
  value_type: U_DWORD_R
  unit_of_measurement: "kWh"

💡 Engineer's Insight

Analysis: Energy generated by PV this month. Measured in Kilowatt-hours (kWh). Total solar energy produced within the current month.

Troubleshooting: Zero may indicate no solar production this month, or a fault/reset of the energy counter. Verify daily generation data.
