Imars Mg5Ktl 2M Modbus Register 5632: Output Peak Power

Technical Definition

The register Output Peak Power at address 5632 is used to monitor output peak power on the Imars Mg5Ktl 2M.

• Protocol: Modbus RTU
• Data Type: U DWORD
• 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 Output Peak Power (Address: 5632)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=5632, 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: "Output Peak Power"
  address: 5632
  value_type: U_DWORD
  unit_of_measurement: "W"

💡 Engineer's Insight

Analysis: Maximum AC power output achieved by the inverter. Units: Watts (W).

Troubleshooting: Zero indicates no AC output or inverter protection trip. Check grid connection and inverter status.
