Sungrow
Overview
The Sungrow SH Series Hybrid Inverter is a residential PV hybrid inverter with integrated battery management, available in single-phase (SH-RS) and three-phase (SH-RT) variants. This ModbusCloud template communicates over Modbus TCP and reads battery state of charge, current, power, and cumulative discharge energy from the inverter's input registers. It also exposes write registers for EMS mode selection and forced charge or discharge commands, enabling active control of the battery. Installers and energy managers gain real-time battery visibility and remote dispatch capability without additional hardware.
Use cases
- Monitor battery state of charge continuously to detect gradual capacity decline across seasons.
- Track cumulative discharge energy to verify battery throughput against the manufacturer's cycle warranty.
- Alert on unexpected battery power readings that may indicate a firmware datatype change after an inverter update.
