Sungrow New Hybrid 2024 SH15-25T Modbus RTU

Installation

1. 1Connect the ModbusCloud gateway RS-485 terminals (A and B) to the Sungrow Com2 connector pins A1 (positive) and B1 (negative).
2. 2Set the Modbus slave address on the Sungrow inverter to match the address configured in the ModbusCloud template (default is typically 1).
3. 3Verify the baud rate on the inverter is set to 9600, matching the template default.
4. 4Do not use the Winet S2 dongle for this template, as several registers are unavailable over Modbus TCP with current Sungrow firmware.
5. 5Import the Sungrow New Hybrid 2024 SH15-25T template in the ModbusCloud portal and assign it to your gateway.
6. 6Confirm data is appearing on the ModbusCloud dashboard by checking MPPT readings and battery state values.
