Description
Sigenergy 20.0 kW SigenStor Three Phase Controller
The Sigenergy 20.0 kW SigenStor Three Phase Controller is a fully integrated, AI-optimized hybrid inverter and energy management system enclosed in an IP66-rated housing. It combines solar conversion, bidirectional battery power conversion, EV charging interface, battery pack communication, and an embedded Energy Management System (EMS) into a single, compact unit. With 20 kW continuous three-phase output, four independent MPPT trackers, multi-source black-start capability, and DC ground-fault protection, it delivers seamless on-grid/off-grid operation, rapid backup switching, and scalable modularity for residential and light-commercial solar-plus-storage installations.
Key Features
5-in-1 Integrated Design
Integrates solar inverter, EV DC charger, battery PCS, battery pack interface, and EMS into one intelligent system.20 kW Continuous Three-Phase Output
Supplies up to 20 000 W of AC power for self-consumption or backup, with a peak boost for short-term loads.Four Independent MPPT Trackers
Optimizes energy harvest under shading or complex PV layouts by managing four separate array inputs.Multi-Source Black-Start
Coordinates batteries, PV arrays, and generators to re-energize critical loads without external grid power.DC Ground-Fault Protection
Built-in detection and isolation eliminate the need for external leak-protection devices.On-Grid & Off-Grid Compatibility
Zero-millisecond transfer between grid, PV+ESS, and generator modes for uninterrupted operation.IP66-Rated Durability
Fully dust-tight and resistant to powerful water jets, suitable for indoor or outdoor installation.AI-Optimized EMS
Embedded AI-driven algorithms enable peak shaving, time-of-use optimization, and system diagnostics via the MySigen app
