Data centers are extremely sensitive to switching times; what performance level does the selected 500kW STS achieve?

The optional 500kW STS features a switching time of under 3 to 5 milliseconds, far exceeding the international CBEMA curve standards for uninterrupted power supply to IT equipment, thereby guaranteeing absolutely seamless, zero-flicker switching for servers.

Does the system support remote monitoring and fault early warning?

Yes. The EMS supports 24-hour remote cloud monitoring. It utilizes AI algorithms to perform millisecond-level big data analysis on battery status, enabling early warnings for thermal runaway.

How long can the 4MWh energy storage capacity sustain data center operations?

It depends on the data center's actual IT load. The system is designed primarily to bridge the critical 15-second gap while diesel generators start up, and to provide sufficient time for technicians to perform system load shedding or data backups in the event of a sudden generator failure.

Project Overview

Project Background

Customer Needs

The center's critical server loads demand extremely high continuity of power supply. However, the local grid is unstable, frequently experiencing instantaneous voltage dips and sudden outages. Although the building is equipped with auto-start diesel generators, there is a 10-to-15-second power vacuum between the moment the diesel engine starts and the time it achieves stable, full-power output.

Solution Design

Integrated ESS Design For Site Operations

An LVK 4MWh fully integrated C&I energy storage container was deployed. The output power distribution core features a 500kW STS (Static Transfer System), acting as a high-power, seamless transfer hub capable of sub-second response, thereby perfectly bridging the power gap during the diesel generator's startup phase.
