My Inverter%206 2Kw Jk Bms%20V15 V19 Modbus Register 4541: Inverter name Max Total Charging Current

Technical Definition

The register inverter name Max Total Charging Current at address 4541 is used to monitor inverter name max total charging current on the My Inverter%206 2Kw Jk Bms%20V15 V19.

• 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 Max Total Charging Current (Address: 4541)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=4541, 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 Max Total Charging Current"
  address: 4541
  value_type: U_WORD
  unit_of_measurement: "A"

💡 Engineer's Insight

Analysis: Specifies the maximum current allowed for charging batteries from all sources combined. Measured in Amperes (A).

Troubleshooting: Overcurrent protection triggered or setting too low for charging requirements. Check battery health and charger settings.
