The modular PCS features modular expansion, Grid-forming control, international certification, and a non-China supply chain. Designed for energy storage, microgrids, AI data center backup power, C&I users, and future grid applications, it supports flexible parallel configuration, distributed deployment, future expansion, and critical load backup. Planned solutions include air-cooled 250kW and liquid-cooled 500kW models, with IP66 / NEMA 4X protection, THDi <3%, efficiency ≥98%, BMS / EMS communication, and multiple protection functions. Certification plans cover UL 1741, UL 1741 SB, IEEE 1547, IEEE 1547.1, and California Rule 21. TECO’s Grid-forming control upgrades PCS from “grid-following” to “grid-supporting,” enabling stable voltage and frequency, virtual inertia, frequency regulation, and voltage support for grid stability and renewable energy integration.
