Description
SigenStor Energy Controller 25.0 kW 3-Phase
The SigenStor Energy Controller 25.0 kW 3-Phase is an advanced hybrid inverter and the central controller of the modular SigenStor system. This device combines a solar inverter and a battery inverter in one compact enclosure, specifically designed to optimize energy management in residential and small commercial installations.
Key Features
The controller is an integral part of a stackable system. It combines essential functions and serves as the foundation for a complete energy storage solution.
- Integrated Functions: Hybrid inverter for PV and battery.
- Modular Architecture: Seamless connection to SigenStor battery modules (6.0 kWh and 10.0 kWh) and an optional backup gateway.
- AI-driven EMS: Integrated smart Energy Management System (EMS) with AI optimization for efficient control of generation, storage, and consumption.
- 4 MPPTs: Equipped with four Maximum Power Point Trackers for maximum yield, even in partial shading.
- AC/DC Coupling: Suitable for both new DC-coupled installations and AC-coupled retrofits of existing systems.
