Description

Product Description

• Centralized energy management controller designed for utility‑scale and commercial PV power plants, energy storage systems, and grid‑integrated installations.

• Supports large networks of connected equipment including inverters, trackers, weather stations, sensors, and meters for holistic plant control.

• Flexible networking with multiple communication protocols such as RS485, Ethernet, and MPLC for system connectivity and scalability.

• Built‑in web interface allows remote operations, maintenance (O&M), monitoring, and firmware updates to reduce onsite service needs.

• Fast reactive power dispatch (reactive control response within 30 ms) using protocols like GOOSE to support grid services and compliance with modern grid codes.

• IP66‑rated outdoor‑ready enclosure with electrical isolation and surge protection on communication ports for robust performance in harsh environments.

• Optional modular expansions such as PID & ISO control boxes, fiber switches, fiber splice boxes, and I/O modules enhance connectivity and system integration.
