Epever Inverter Entities Sensor Modbus Register 12558: Inverter name Load Output Power

Technical Definition

The register inverter name Load Output Power at address 12558 is used to monitor inverter name load output power on the Epever Inverter Entities Sensor.

• Protocol: Modbus RTU
• Data Type: U DWORD R
• Unit: W
• 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 inverter_name Load Output Power (Address: 12558)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=12558, 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: "inverter_name Load Output Power"
  address: 12558
  value_type: U_DWORD_R
  unit_of_measurement: "W"

💡 Engineer's Insight

Analysis: Indicates the real power consumed by the connected load. Measured in Watts (W).

Troubleshooting: Zero means no load is active or inverter is off. Verify load operation and inverter output status.
