Junlee's energy storage systems provide energy storage and output management in power generation. The lithium-ion battery technology and renewable energy power generation technology form a joint system. Through the high-level consistency of cells and the powerful computing of BMS, Junlee enables the power generation to restore a stable power grid, optimize the power output curve, reduce solar and wind curtailment, provide system inertia and the functions of frequency and peak modulation, increase the proportion of renewable energy in total power generation, and optimize the energy structure.
