Sigenergy SigenStore EC (grid)
Sigenergy
Overview
The Sigenergy SigenStore EC is a modular hybrid energy storage system combining a hybrid inverter, battery power conversion, and integrated energy management. Compatible with the Sigen Hybrid and Sigen PV Max, it connects to residential and small-commercial grids. This Modbus TCP template reads the grid connection point over function code 3, covering active power at the meter boundary, cumulative energy throughput, and per-phase currents on phases A, B, and C. The ModbusCloud Gateway polls slave address 247 on port 502, giving installers a live, per-phase view of import and export without manual data collection.
Use cases
- Monitor real-time grid active power to verify the system is staying within contracted import limits.
- Track cumulative grid energy to produce monthly import and export reports for billing reconciliation.
- Alert on sustained positive grid power during peak tariff hours to catch unexpected import events.
- Compare per-phase currents on A, B, and C to detect phase imbalance before it trips protection.
