Sigenergy SigenStore EC (battery)
Sigenergy
Overview
The Sigenergy SigenStore EC is a modular LiFePO4 home and small-commercial energy storage controller, compatible with Sigen Hybrid and Sigen PV Max inverters. This template connects over Modbus TCP and reads the plant-level battery state of charge, ESS power flow (charge or discharge direction), and cumulative energy throughput. The writable minimum-SOC setpoint lets an external EMS hold a reserve for backup. With the ModbusCloud Gateway polling these registers, operators gain continuous visibility into storage behaviour across one or multiple sites.
Use cases
- Monitor real-time battery charge and discharge power to verify the SigenStore EC follows the expected EMS dispatch schedule.
- Track state of charge continuously to detect gradual capacity fade across months of operation.
- Alert on SOC dropping below a defined threshold during evening peak hours to catch grid-import overruns.
- Report cumulative energy throughput over time to validate warranty cycle-count claims for the SigenStore EC.
