Grid‑Tied Energy Storage Backup Power BESS System for Critical Load Protection

This grid‑tied BESS backup power solution is designed for sites requiring critical‑load power protection. The system consists of utility grid, STS/ATS automatic transfer switch, PCS power conversion system and BESS battery energy storage system.

Under normal conditions, the utility grid supplies power to loads. Once grid failure occurs, STS/ATS will activate fast automatic switch‑over. BESS instantly takes over power supply via PCS to avoid power interruption for important devices. It raises power‑supply reliability and satisfies partial backup‑power demands.

Widely applied for critical infrastructure projects: data centers, hospitals, telecom base stations and other facilities that cannot afford power outages.
