Commercial ESS

The new CPS ESS solution integrates 125/250 kW two-hour energy storage building blocks that can be easily expanded to meet any C&I project size. Modular design minimizes the impact of faults and their associated O&M costs. Rack-level management reduces mismatch losses between parallel battery cabinets, and also enables battery mixing and phased replacement. The CPS bi-directional power conversion system (PCS) acts as the mediator between the generation source, the grid, and the battery rack for commercial energy storage applications.
