Sungrow
Overview
The Sungrow iHomeManager (iHM) is a residential home energy management system that coordinates PV generation, battery storage, EV charging, and load control within a Sungrow installation. This template reads the iHM's PV power register via Modbus TCP, giving the ModbusCloud Gateway a direct source for live solar yield data. When the iHM is installed, the connected inverter no longer exposes grid and generation data on its own Modbus interface, making direct iHM polling essential. Tracking PV power through this template keeps your portal's energy dashboards accurate without relying on the iSolarCloud API.
Use cases
- Monitor live PV generation power to verify that solar yield matches expected output for the installation size.
- Track daily PV power trends in the ModbusCloud portal to detect module soiling or shading that reduces yield.
- Alert on sustained low PV power during daylight hours to identify inverter communication or generation faults early.
