Description
Sigenergy 25.0kW SigenStor Three Phase Controller
The Sigenergy 25.0 kW SigenStor Three Phase Controller is a fully integrated, AI-optimized hybrid inverter and energy management system in an IP66-rated enclosure. It combines solar conversion, bidirectional battery power conversion, EV DC-charger interface, battery-pack communication, and an embedded Energy Management System (EMS) into a single unit. With a continuous three-phase output of 25 kW, up to four independent MPPT trackers, multi-source black-start capability, and DC ground-fault protection, it delivers seamless on-grid/off-grid operation and rapid backup switching for residential and light-commercial solar-plus-storage installations
Key Features
5-in-1 All-In-One Design
Integrates solar inverter, EV DC-charger, battery PCS, battery-pack interface, and EMS into one streamlined system25 kW Continuous Three-Phase Output
Supplies up to 25 000 W of AC power (nominal) with short-term peak capability for high-demand loadsUp to Four MPPT Trackers
Four independent maximum power point trackers optimize energy harvest under shading or uneven array layoutsMulti-Source Black-Start
Coordinates battery storage, PV arrays, and backup generators to re-energize critical loads without external grid powerDC Ground-Fault Protection
Built-in detection and isolation meet safety standards without external leak-protection devicesIP66-Rated Durability
Fully dust-tight and protected against powerful water jets, suitable for indoor or outdoor installationAI-Optimized EMS
Embedded machine-learning algorithms enable intelligent peak shaving, time-of-use optimization, and system diagnostics via the mySigen appVehicle-to-Home & Vehicle-to-Grid Ready
EV integration allows the controller to work with bi-directional EV chargers for V2H/V2G applications, expanding virtual grid capacity
