Understanding DC Coupled vs. AC Coupled Systems
DC coupled battery energy storage systems connect direct current (DC) energy sources, such as solar panels, directly to batteries, optimizing efficiency by minimizing conversion steps. This system contrasts with AC coupled setups, where direct current must first be converted to alternating current (AC) before being stored in batteries, resulting in higher energy losses. The discussion highlights that only one grid connection is needed for DC systems, while AC systems require additional infrastructure like step-up transformers and switchgear. As a result, DC coupled systems present a more streamlined and efficient solution for energy storage integration into the grid.
