The installed capacity of the energy storage industry keeps expanding. Grid-forming energy storage and industrial & commercial energy storage PCS impose stricter requirements on power conversion efficiency and round-the-clock operational stability. Traditional silicon-based devices have relatively high operating losses, leading to massive electric energy waste in long-term operation and increasing the operating cost of energy storage power stations. With the material characteristics of high frequency, low loss and high voltage resistance, silicon carbide has become the preferred device for upgrading new-generation power conversion systems.

SiC devices can raise the overall conversion efficiency of PCS by 1.5%~3%. Large-scale energy storage power stations can obtain considerable benefits from increased power generation during long-term operation, which can fully offset the material cost premium of silicon carbide devices. The high-temperature resistance of SiC adapts to the sealed high-temperature environment of energy storage containers and reduces the probability of equipment shutdown triggered by overheat protection. Supported by the mature mass supply system of domestic SiC products, pin-to-pin replacement of original silicon devices can be realized without PCB revision, shortening the iteration cycle of energy storage products.

All delivered products pass energy-storage-specific reliability tests including long-term high-temperature durability, damp-heat cycling and lightning surge tests. They are applicable to household energy storage, industrial & commercial energy storage and large-scale grid-side energy storage scenarios. We provide sample testing and technical docking services to help energy storage manufacturers improve system energy efficiency and cut long-term operation and maintenance costs.
