Description
Sigenergy 5.0kW SigenStor Single Phase Controller
The Sigenergy 5.0 kW SigenStor Single Phase Controller is a versatile hybrid inverter and energy management unit tailored for residential and light-commercial solar-plus-storage installations. It combines MPPT solar charging, battery bidirectional conversion, and an embedded Energy Management System (EMS) into a single IP66-rated enclosure. With up to 98 % efficiency, multi-source black-start capability, DC ground-fault protection, and remote monitoring via the MySigen app, this controller ensures reliable, safe, and optimized energy flow between PV arrays, battery banks, the grid, and backup loads
