Single Pow Hvm62K 48V Lip Modbus Register 225: Inverter Loadname suffix

Technical Definition

The register Inverter Loadname suffix at address 225 is used to monitor inverter loadname suffix on the Single Pow Hvm62K 48V Lip.

• Protocol: Modbus RTU
• Data Type: S WORD
• Unit: %
• 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 Loadname_suffix (Address: 225)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=225, 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 Loadname_suffix"
  address: 225
  value_type: S_WORD
  unit_of_measurement: "%"

💡 Engineer's Insight

Analysis: Power consumed by the inverter's internal loads or auxiliary systems in Watts (W).

Troubleshooting: Non-zero is expected. 0 could indicate inverter shutdown or malfunction.
