ZTT Battery Energy Storage System – Grid Side BESS

ZTT started on Optical Fiber Communications in 1992, accessed Smart Grid in 2002, and commenced work on the Renewable Energy field in 2012. With over 30 years of sustainable innovation, ZTT helps make a wide variety of products across industries. Ever since it first started developing the Lithium-ion battery and BESS, ZTT has expanded a new era of focusing on power delivery and energy storage optimization.

Grid-side BESS

Grid-side energy storage helps balance the supply and demand of power generation, distribution, and consumption. This avoids over-generation on the grid side and reduces the power supply gap in the grid. Moreover, it can improve the utilization efficiency of power generation equipment and reduce the investment in grid construction. Thus it provides a strong guarantee for the safe and stable operation of the grid system.

ZTT 6MWH BESS Project (Container type)

The system consists of three 500kW/2MWh subsystems. One subsystem is connected to a 630kVA booster transformer. And the other two subsystems are connected to a 1250kVA dual-split booster transformer, boosting to 10kV and connected to the grid.


As knows, it is for 10kV-side peak clipping, valley filling and load tracking in ZTT industrial park. Meanwhile, it combines with photovoltaic to effectively smooth PV output and improve power quality.
