With growth in the electric vehicle (EV) market slowing, global battery manufacturers are shifting their focus to the ESS (Energy Storage System) market. As renewable energy expands and demand for power grid stabilization increases, ESS is rapidly emerging as a next-generation core growth sector.

The era of “producing electricity and using it immediately” is coming to an end. Technologies that store surplus electricity and utilize it efficiently are now at the center of national energy strategies. This is where ESS (Energy Storage System) plays a critical role.

ESS acts as an intermediate storage hub connected to the power grid, bridging the time gap between power generation, storage, and consumption. Previously limited to peak-load support, ESS has evolved into a key system that stabilizes power quality when integrated with variable renewable energy sources such as solar and wind.

Qlight has established itself as an “energy safety signaling partner”, providing both visual and audible indication of key equipment status within ESS facilities and immediately alerting on-site personnel or remote operators to potential hazards.

ESS facilities consist of multiple power components such as PCS (Power Conditioning System), BAT (Battery Racks), and EMS. Visualization devices are an essential element for integrated control across these systems.

Qlight applies a wide range of technologies—including wireless control, remote alerts, high-brightness LEDs, and voice warnings—optimized for ESS environments. In the ESS sector, Qlight’s QPL and QEL series lighting solutions are already supplied to global companies such as BYD, proving their reliability and quality.
