Epever Scc Entities Sensor Modbus Register 36871: Scc name Boost Charging Voltage

Technical Definition

The register scc name Boost Charging Voltage at address 36871 is used to monitor scc name boost charging voltage on the Epever Scc Entities Sensor.

• Protocol: Modbus RTU
• Data Type: U WORD
• Unit: V
• 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 scc_name Boost Charging Voltage (Address: 36871)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=36871, 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: "scc_name Boost Charging Voltage"
  address: 36871
  value_type: U_WORD
  unit_of_measurement: "V"

💡 Engineer's Insight

Analysis: Voltage setpoint (V) for the boost charging stage. Higher than float voltage to ensure full battery charge.

Troubleshooting: Incorrect value can result in incomplete charging or unnecessary stress on the battery. Match battery manufacturer recommendations.
