Epever Inverter Entities Sensor Modbus Register 12557: Inverter name Load Output Current

Technical Definition

The register inverter name Load Output Current at address 12557 is used to monitor inverter name load output current on the Epever Inverter Entities Sensor.

• Protocol: Modbus RTU
• Data Type: U WORD
• Unit: A
• 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 Current (Address: 12557)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=12557, 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 Current"
  address: 12557
  value_type: U_WORD
  unit_of_measurement: "A"

💡 Engineer's Insight

Analysis: Represents the current flowing to the load connected to the inverter. Measured in Amperes (A).

Troubleshooting: Zero indicates no load connected, load circuit breaker tripped, or inverter fault. Check connections and load status.
