Energy Storage — Power Conversion

The core of every
BESS installation

The PCS (Power Conversion System) is the critical link between battery storage and the electrical grid. It handles bidirectional DC/AC conversion — charging batteries from the grid or solar, and discharging stored energy back to the load or grid on demand.

Forte PCS systems feature a fully modular architecture. Start with a single 105kW cabinet and scale to 100MW+ by adding modules and cabinets — without redesigning the system. Every module is hot-swappable for maximum uptime.

With integrated EMS (Energy Management System), MPPT solar inputs, and on/off-grid switching within 20ms, Forte PCS delivers a complete power conversion solution for commercial, industrial and utility-scale energy storage.
