Deye Inverter Entities Sensor Modbus Register 112: Name inverter name pv2 current

Technical Definition

The register name inverter name pv2 current at address 112 is used to monitor name inverter name pv2 current on the Deye 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 name inverter_name pv2 current (Address: 112)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=112, 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: "name inverter_name pv2 current"
  address: 112
  value_type: U_WORD
  unit_of_measurement: "A"

💡 Engineer's Insight

Analysis: PV2 input current (A). Current from the second solar panel string. Reflects power from the second array.

Troubleshooting: Zero current with voltage points to an issue on the second string. Inspect connections and wiring for faults.
