Modbus TCP
Sigenergy Sigen Hybrid (battery)
Sigenergy
Overview
The Sigenergy Sigen Hybrid is a residential and light-commercial hybrid inverter with integrated battery storage, combining PV management, AC grid connection, and battery control in a single unit. This Modbus TCP template reads battery power, cumulative energy throughput, and state of charge from the Sigen Hybrid, Sigen PV Max, and SigenStore EC, and writes a minimum-SOC limit setpoint via a holding register. Import it into ModbusCloud to track real-time battery behaviour, enforce discharge limits, and build historical energy reports without additional hardware.
Use cases
- Monitor battery state of charge continuously to verify the system stays above the configured discharge floor.
- Track cumulative energy throughput over months to detect capacity fade or abnormal cycling patterns.
- Alert on battery power dropping to zero unexpectedly to spot grid-connection or inverter faults early.
- Compare instantaneous battery power against site load data to verify self-consumption targets are being met.
