Improved Energy Storage Systems with SiC Solutions from onsemi

ESS (Energy Storage System) is a crucial part on the path to net zero because it enables human store and control the renewable energy like solar and wind which is dynamic and unstable. A well-established energy storage system can store/ contribute energy for later use which reduces electricity cost/pressure during the valley/peak of electric consumption.
