Energy Storage Systems (ESS) store energy and stabilize electrical performance in large grid installations as well as medium commercial to residential establishments. Lithium-ion batteries are the basic building blocks of ESS and together with inverters or Power Conditioning Systems (PCS) help the ESS manage peak and off-peak power requirements of the locality or household.
Residential ESS found in smart homes come with wall-mounted batteries or modules and are coupled with AC/DC Inverters. For commercial or industrial establishments, several of these modules stack up to form racks while multiple such racks are arranged within a container which works as the commercial ESS for large smart grids. The excess power produced by renewable energy resources like solar and wind power are captured by ESS, avoiding massive frequency fluctuations, thereby boosting the reliability and power quality of the grid. Amphenol provides a range of high-power connectors and many more advanced interconnects for ESS.
