Utility ESS Solution

Product Description

Relying on the advanced Lithium-ion Iron-Phosphate battery technology, BYD can provide large-scale energy storage systems, distributed energy storage systems and micro-grid systems. Based on these systems, BYD can provide a complete power solution realizing power output smoothing, peaking shaving, frequency regulation, transient active power responding and transient voltage supporting, to keep the power system running safely, stalely and reliably. These solutions can be used for frequency regulation, voltage compensation transition deferral and power quality management in the power system.


BYD mainly provides two kinds of indoor/outdoor solutions for on-grid, off-grid and hybrid use. BYD energy storage systems can be fit for various needs based on its flexible and modular design.
